Now, I’m going to turn it over to our guest, Doctor Gille. Do you mind sharing a bit about yourself before you start?
Marianela Gille 1:55
Of course. Hi, everybody. Nice to see you all. Thank you for making the time to join us this evening. I know you’ve had long days today, but hopefully this session will be very helpful to understand a little bit more about fertility and more than anything, when it’s important to start testing or when we need to start looking into things.
I’m Marianela Gille. I am originally from the border town of Matamoros, Mexico, and I’ve been in the United States pretty much since I was 18. I am an OB-GYN by training, and I’ve been here at Pozitivf Fertility for about a year and a half. I’m currently working out of the San Antonio location, and I go visit the Houston location about once a month, and I will soon be in the Austin, Texas location, which should hopefully be opening soon.
And I’ll go ahead and kick it off. So a lot of this is meant to be basics as far as just when to start looking into fertility workups, when is waiting too long, when should you keep trying on your own? So hopefully I can give you some tools today so that you can feel comfortable knowing like, am I okay to keep trying on my own? Or Do I need to start being more proactive?
So the traditional one year rule, if any of you have been to your OB-TYN and said, I’ve been trying to get pregnant, this is usually the criteria that they will use before they can determine if you should be getting any additional testing at that time or not. Now, this rule does not apply to everybody.
But in general, if you are under the age of 35 years young, you want to seek a fertility consult after 12 months of having intercourse. And it’s not having intercourse every day. If you’re having intercourse at least two to three times a week, you’re very likely covering the ovulation window.
Okay. So if it’s been a year and you still have not gotten pregnant, that’s a good time to start looking into additional workup. If you’re above the age of 35, then at that point, it is important to take action once you get to about the six month mark.
And why is that? It’s because we know that with age, the egg count, not only the quantity, but the quality will drop. And we’ll talk about that a little bit further shortly. So in general, that’s your general timeline, right? Less than 35 years young, you want it to be for a year of trying.
Over 35 years young, you want to go ahead and start looking into it if it’s been six months of trying.
Now, there are exceptions. If you have a history of endometriosis, of polycystic ovarian syndrome, of any other condition that could affect fertility, thyroid issues that are uncontrolled, you may want to look into it earlier.
So this again applies to patients that don’t have any significant medical history and are trying to get pregnant. But if there’s anything in your history that potentially could impact your fertility, it may be important to start looking into it sooner rather than later.
Unfortunately, like with many things in life, women don’t have, men have things a little bit easier. So their sperm can be good for a very long time. But as women, our quality and quantity of eggs does start dropping. So that is why we do need to be a little more proactive. Okay.
Now, why waiting isn’t always winning? At the end of the day, it can also take an emotional toll. Tracking your cycles, checking your temperatures, using the apps, negative tests month after month can be really exhausting and it could just overall be very overwhelming. In general, if you don’t necessarily need to wait the entire year before you even start getting a little bit of a workup, you can always start with something as simple as an AMH, which I’ll talk about in a little bit more detail right now. And at the end of the day, having information, right, knowledge is power. So that’ll help you to make a guided decision, like, okay, should we keep trying on our own, or do we need to be more proactive at this point?
Now, let’s talk about AMH first. AMH is a blood test that checks for a hormone called the anti-Mulverian hormone. Okay? It’s a blood test you could get done with your gynecologist. You can get it done here with us. And essentially, the AMH does not tell me if you’re going to get pregnant or you’re not going to get pregnant.
What it tells me is, or it gives me an idea of where your current egg account stands, okay?
At the end of the day, we know that for us women, our ovaries are like a little bank that holds all of the little eggs that we will have in our lifetime. And the AMH gives us an idea, are we at the average? Are we above the average we should be our age? Or are well below the average, okay? And then the AMH also does not tell me anything about the quality of the eggs. It’ll tell me a lot about the quantity, but that’s where age becomes a really important factor. And I’ll show you all a little graph right now that’ll help to depict this better, okay? So essentially the AMH is a way of getting a little bit of a baseline to get an idea of where we’re starting from.
Now, what happens during the standard workup? In a standard fertility workup, generally we do the AMH blood test, an ultrasound, which will usually check your ovaries, your tubes, and your uterus, and then also a semen analysis is really important.
OK, this can all be done within a day.
Now, I’m going to make fertility really simple. If any of you have been to one of our consults here, this is usually what we start with. It’s really important for our patients to understand what is going on with their body and to understand fertility. And the reality is a lot of people want to make fertility really complex, but fertility can be very straightforward. We need three things to get pregnant.
We need sperm, we need eggs, and we need a place for them to get together, which is the uterus. Now, in order to evaluate these three components, for the sperm, we do the semen analysis. For the eggs, we do the AMH that we just mentioned, that anti-Mullerian hormone, and the AFC, which is the follicle count.
And for the uterus and tubes, we do imaging, and I’ll go into each one of these in details.
So these are the general parameters of a normal semen analysis. When you send your partners in to get this done, we’ll go ahead and run through all of the results and see if there’s anything that would cause any issues. Different things that we check for, like the total volume, the concentration of the sperm, the motility, which is how the sperm moves.
The morphology, which is how the sperm looks. The sperm needs to have a very specific shape so that it could penetrate the egg. And then the total motile sperm combines all of these numbers and it gives us a general range. And this is again to get pregnant by nature. Even if your semen analysis results are not great, there’s also treatment options that can help with this.
Now, when we talk about eggs, this is a little depiction that shows that when we are born, we’ll look right here, we know that most women are born with anywhere between 1 to 2 million eggs on their day of birth. And then over their lifetime, that number will start to decrease. And by the time we hit menopause, that’s when we’re running out of eggs.
Now, if we’re born with about 1 to 2 million, by the time we get to our first period, we’re already at 400,000. We’ve lost more than half of our eggs without even having a period. After that, the number will continue to drop, and we start to see a faster decline after the age of 37.
So most of our patients that come and see us are anywhere from 35 to 42. There’s some younger, there’s some older, but let’s use 35 as a general reference. A woman that comes in at 35 years young, we know that she should have about 50,000 eggs. 50,000 sounds like a lot of eggs.
But it’s not like we can just use all of the eggs, right? Every month, the ovary gives us a batch of eggs to use, and our brain’s hormones and the ovarian hormones will coordinate to see if anything starts to develop, which would be like a little follicle growing and a little egg inside of it. When we start doing treatments like
IUI or IVF, the medicine that we give helps to get more of those follicles to develop at the same time.
Now. When you come in for an ultrasound, the other thing that we check for is the follicle count. So we’ll take a look at both ovaries and we’ll count all of the little circles that are on the ovary, which are the little follicles that the ovary has given your body that month to work with. Again, by nature, your body will usually pick one little follicle to grow so that it can release an egg. But there is a certain amount of follicles that we should see at any given time at a specific age range. So for example, at the age of 35 years young, we should see about 20 follicles, so about 10 on each ovary. If that number is lower, if we’re looking at 10 to 15, then we know that maybe you’re not at the 100,000 eggs. You might be lower than that, right? And at that point, sometimes it’s important to be more proactive about our fertility because we know that your egg count may be dropping faster than another woman at the age of 35. Now, the other thing we look at is that AMH, what we had discussed, right?
And that is also very age-based. At the age of 35 years young, the AMH should be somewhere between a 2 to a 3.5.
I can tell you when I used to practice general gynecology, we were always taught anything between a one to a four is normal. So if we had a 25 year old that had an AMH of 1.5, we were taught to say that is normal. But the reality is that the age of 25, an AMH of 1.5 can be very low.
Because if that woman were to wait another 5 to 10 years to have a baby, and that AMH drops below 1, that can make it a lot more difficult to get pregnant, especially if she’s trying to plan for a family of two or three kids. So it is very important to interpret AMH based off the age as well, okay?
Now, here’s the other component, right? One thing we said was the quantity of eggs. The quality of the eggs we know changes over time.
So as we age as women, these eggs have been in our body since we were in our mother’s womb. Okay? So for that 35-year young women, those eggs were created 36 years ago by her mother, which means that over time, there can be more genetic defects in the eggs that are there. So that’s why we know that as we increase with age, we see that the amount of abnormal eggs goes up. So about 35, we have about 20% of eggs that are normal, sorry, 20% of eggs that are abnormal.
80% will still be normal. Look at the big jump by the time we get to the age of 40. 50% of the eggs will be abnormal and 50% will be normal. And by the time you get to 42, we’re looking at about 70% abnormal. 45, we’re looking at about 90% abnormal.
So that’s why it is important to take action, especially if you’re considering a family of 10, two or three kids, because we can’t just think about that first pregnancy. We have to be thinking about second and third pregnancy as well when we’re doing our overall assessment and treatment plan.
Now, another component too that we see with direct correlation with age is that as women age, we know that the amount of miscarriages goes up. And that makes sense, right? If these eggs have been in her body for a longer period of time and start developing more genetic or chromosomal errors, then at that point, there’s a higher risk of miscarriage as we become older.
The third component that we mentioned was the uterus and the tubes, right? So generally the eggs are stored here in the ovary. And if we have normal menstrual cycles about once a month and we’re ovulating, that egg will get released from the ovary into the tube and it will try to make its way into the uterine cavity.
Sperm will be deposited in the vagina so that it could try to make its well into the cavity and the tube. And that’s where we generally create an embryo so that it could try to implant itself back inside of the uterus. So that’s why all of these components here are very important, okay?
Here at Pozitivf, we can do both tests within 10 to 20 minutes. It’s a simple procedure called a saline infusion sonogram and HyFoSy (hysterosalpingo-foam sonography). The saline infusion sonogram, basically what we do is that we put a little catheter right through the cervix. It’s a tiny little straw like the size of a spaghetti noodle. And we go ahead and fill the uterus up with water so that we can see the cavity and make sure that there isn’t any growths or abnormalities.
You’ll be able to see this in real time as it’s happening. And ideally, we want to make sure that the cavity is super smooth, kind of like this, so that there isn’t anything unusual.
What does it look like when there’s something unusual? I’ll show you out here. This is an example of a cavity that has either polyps or fibroids that are little growths inside of the uterus. And these can become problematic because if a little embryo is hanging around in the uterus and it tries to implant itself, and accidentally sticks onto a polyp or a fibroid, it may not get the nutrients or the blood that it needs in order to develop into a healthy baby, and those can end up in a miscarriage.
Generally, once we diagnose one of these, either a polyp or a fibroid, we recommend what’s called a hysteroscopy, which is a procedure to clean out the uterine cavities so that we can leave a really nice smooth surface, kind of like the one here on the left, so that the embryo can have a better chance of sticking right where it needs to.
Now, the high flow C is a different solution. So first we’ll put water in, or saline, just so that we can see inside the cavity. Then that saline will come out. And then we put another liquid that has a little bit of a foamy texture so that it can go into the tubes and determine if the fallopian tubes are open or not.
So it looks something like this. Again, you would be able to see this in real time as we’re doing it, so we get answers right away. And at the end of the day, there’s many patients that get to this point. We’ve done all the testing. The cavity looks normal. The tubes look normal. The ovarian count is normal and yet they’re still not able to get pregnant.
So that diagnosis is called unexplained infertility. And while it can be the most difficult diagnosis to process because you don’t have an explanation, it is also the most treatable diagnosis.
Why? Because there’s healthy eggs, there’s healthy sperm, and there’s a good uterus. The reality is that all of the testing that we do sees everything from a really big picture. We don’t know what’s going on at the microscopic level, right? We can have a healthy egg and a healthy sperm, but for some reason, maybe it just cannot penetrate the shell. We can have a healthy looking tube, but we don’t know what’s going on at the microscopic level inside of the tube, so that if the sperm and the egg aren’t able to find each other, that becomes a problem.
Ligia Popescu 17:51
We have a question, yes. Are both tests required?
Marianela Gille 17:51
Generally, you want to get an assessment of both, because if you don’t get both the tubes and the uterine cavity checked, you’re essentially getting only a piece of the puzzle. And when you’re trying to determine, like, do I need additional treatment, you want to make sure to have all of the answers before you start going down the path of something like an IUI or an IVF. I’ll give you an example.
If the tubes are blocked or closed and you did the saline and the cavity looks beautiful and everything looks great, and you try something like an IUI or conceding naturally, if those tubes are blocked, that sperm and egg are never going to find each other. So yes, I would say we definitely recommend both the saline and the HyFoSy.
More questions coming in.
Is unexplained infertility diagnosed before a laparoscopy? So yes, unexplained infertility can be diagnosed before a laparoscopy. There is some providers, because everybody has different ways of managing medicine, that believe that doing a laparoscopy to take a look inside the cavity to see if there’s any signs of conditions like endometriosis or something more complex.
But the reality is that while that can sometimes be the case, if all the components look normal and there’s no signs and symptoms of something like an endometriosis, you do not need a laparoscopy to make a diagnosis of unexplained infertility.
If anyone else has questions, please feel free to put them on the chat, send them through TikTok. We’re here to answer anything you all want to know.
Okay.
Very often when we have patients come in for their very first new patient appointment, we call it, they are nervous, of course. They’ve never been into a fertility practice. They don’t know what to expect. So just to give you a general reference, when patients come here to Pozitivf, we generally already have their blood work and their semen analysis results in.
So by the time you show up, we schedule you first for an ultrasound, and we’ll come in and do an ultrasound that takes about anywhere between 10 to 20 minutes, where we’ll do both the full follicle count, the saline, the HyFoSy.
And with that, we’re able to get all the components that we need to make an assessment and determine
what the cause is of infertility and what the best treatment outcome is. I can tell you most patients by the time we’re done with the ultrasound, tell me like, oh, that wasn’t as scary as I thought it was going to be.
Or patients that have previously had something called an HSG, which also looks at the tubes, will generally say like, wow, this was way less uncomfortable than I was expecting because HSGs can be a lot more uncomfortable. So if you’re normal or you’re scared, that’s very common. And don’t worry, we will always have somebody here to guide you through all of the steps so that you feel really comfortable through the process.
Okay, next question is, if all initial tests come back normal, does that mean that there is nothing wrong? So going back to the testing that we do, looks at everything very big picture. It’s really hard to see what’s going on at a microscopic level.
So it’s always very reassuring when we see that things look normal. And again, that is the best prognosis going forward because we know that we have good components so that we can work with the sperm, the eggs, and the uterus to help get to a healthy pregnancy. And again, I think it still is the hardest diagnosis because it’s usually easier when you have an explanation as to why something isn’t working out. It’s a lot harder when you’re like, well, I don’t know why it’s breaking out. You’re telling me everything is normal and now I need to get treatment.
Any other questions? Yeah. I have an endometioma and kissing ovaries, but can get pregnant. Can get pregnant with laparoscopy be next.
The question was, I have endometriosis and kissing ovaries. Would A laparoscopy be the next best step? The answer is it depends. If you can get pregnant and you’ve never tried to get pregnant before, there is a lot of women with endometriosis that carry completely healthy pregnancies.
One thing that patients with endometriosis will learn through their process and notice even before or after surgery is that sometimes the surgery can help to get rid of some of the endometrial tissue that’s stuck inside of the pelvis, or in the case of an endometrioma, it can remove the endometrioma.
But the surgery itself can also damage the ovaries and damage the egg reserve. So you generally A, want to get operated by somebody who’s really well versed with endometriosis, just so that they can make sure to guide your or to take care of your ovarian tissue as much as possible.
And additionally,I would say you don’t always necessarily need to get a surgery done before pregnancy. If you’re having difficulty getting pregnant, or if you’re having miscarriages, then at that point, a laparoscopy may be the best next step. Right?
Ligia Popescu 24:09
What would it mean if you came, if you had a sperm analysis and it was abnormal? What could you do about it?
Marianela Gille 24:17
Great. So, and that’s a great question. Thank you. And I’ll clarify. Men’s sperm does start to suffer a little bit with age. They just don’t run out of it, right? So a man could be 80 years old and still produce sperm. The quality is probably not going to be as great, or it’s definitely not going to be as great as somebody that’s 40 or somebody that’s 30.
So again, their quality will suffer a little bit, but the quantity maybe not as much. Now, let’s say that there is a sperm issue. It depends what type of a sperm issue it is. If the concentration is low or if there’s an issue with the motility, sometimes doing a treatment like IUI, intrauterine insemination, could be an option because maybe the sperm is just having difficulty getting all the way from the vagina into the tube. For us, it doesn’t look that far, right? For us, it’s like, oh, that’s like maybe 6, 7 centimeters. But for the sperm, it’s like running a full marathon. And the idea is that when you do an IUI, you take the sperm, first they do a wash so that they can get the best swimmers. And then they put those all the way inside of the uterus, close to where the egg is going to drop, it’s essentially like putting it right at the last mile before the end of the marathon, right? So that could be an option.
Now, if we start looking into other sperm issues like the morphology, which is how the sperm looks, right? If the sperm isn’t perfectly shaped to try to penetrate the egg, or if the concentration is really, really low to the point where it’s not going to be a good option to do an IUI, then sometimes the best next step is to do an IVF. Because with IVF, you don’t need the millions of sperm. You just need a few good swimmers. And essentially with IVF, what they’ll do is that they’ll also pick the best swimmers and they will put the sperm directly inside of the egg in a process called ICSI.
So that bypasses the morphology issue, right? It doesn’t need to be perfectly shaped to penetrate the egg because we’re forcing it directly inside of the egg. So those are two options of treatments that we can do.
Ligia Popescu 26:18
Wonderful. We do, yes. And we do have another question. When as an when an individual has endometriosis, is suppression before IVFFET recommended?
Marianela Gille 26:18
Great question. So the question is, if when patients have an endometriosis diagnosis, do they always need to be on suppression before the embryo transfer? And the answer is not necessarily. In fact, most patients with endometriosis will still get pregnant and carry a perfectly healthy pregnancy, without being on any suppression. And suppression is no joke, right?
For any of you that have ever been on suppression or heard of friends that have been on suppression, those hormones can really impact you, right? Essentially, you’re putting your body into a medical menopause, some people call it, or it’s even like medical puberty because your hormones are just not being produced.
You’re going to start feeling hot flashes, mood changes. And all in all, it is sometimes recommended, but not always. I would say if you have a stage 3, stage 4 endometriosis diagnosis, or you’re having really severe symptoms, it could be a strong consideration. If it’s a mild endometriosis or a stage one, stage two,..
Sometimes it’s better to go forward with the transfer.
Here’s the other thing, especially if you have multiple embryos. If you have only one embryo left and this is the only embryo you’re going to get a chance to do it with, then that can be another consideration for suppression. So I do think it’s very based off the patient and the full picture, not just one component.
But to answer your question, no, we don’t necessarily always need to put somebody on suppression before the transfer.
Ligia Popescu 28:02
Wonderful.
Marianela Gille 28:03
Question from TikTok. How did, how I, hello, I did my time intercourse procedure. How many days after the shot can I do a pregnancy test?
So we have somebody that’s been doing timed intercourse and she’s asking how many days after the shot to do the pregnancy test. I’m assuming that this is an HCG shot, which is an injection that tells your body to ovulate. And if that is the question, we would recommend doing a pregnancy test.
Maybe about, I would say 11 days afterwards, you may start to see some positives. Generally, whenever you would expect your next period is a good time to start testing.
I lost my left tube due to an ectopic and the right tube has a distal Tubal blockage – do I need IVF?
Yes, the question is, this patient lost her left tube due to a ectopic pregnancy, and the other tube has a blockage. Essentially, these tubes are damaged, right? One of them is not present. The other one that’s there has a damage to it. It’s going to be very difficult for that sperm and egg to find each other, if not almost impossible.
So yes, at that point, an IVF cycle is definitely the next best step.
Will I need meds if I already ovulate?
Well, the question is, will you need medication if you already ovulate? If you’re already ovulating and you’re trying to do timed intercourse, you don’t necessarily need to take medication. If you’re doing something like an IUI, we generally recommend medication. Why? Because you’re putting a lot of time and effort into something.
To have this be a month that you end up not ovulating. And it happens. Even if you have perfectly regular periods once a month, you may not necessarily ovulate every single time. So the medication sometimes helps to ensure that the ovulation is more likely to happen if you’ve already gone through the process of preparing for a procedure like this.
IUI. And for IVF, you definitely need medications. There is some ways to do it where you may not need them, but the reality is that it’s a really complex process. And without medication, at most, you’ll get one egg. And with one egg, that’s a really, really low guarantee that you would end up with a healthy baby.
Marianela Gille 30:32
Next question from the chat. I’m 39, not ready to have a baby and interested in freezing my eggs. What does the testing process look like for this? Would it make more sense to freeze egg now or try IVF in a few years if I have issues getting pregnant? This is a wonderful question.
Marianela Gille 30:52
At the age of 39 years young, I would strongly encourage you to consider freezing the eggs now.
Why is that? Let’s say you’re ready to have a baby in the next year, two years, three years. The difference from 39 to 42, even to 41, is pretty significant as far as quality. I can tell you patients that end up with eggs from 39 years young versus 41 years young have a way higher possibility of creating a healthy embryo.
Once you start getting past the 40s, it makes it a little bit more difficult. So if you have the time and you can, this is the best moment to do it.
In fact, we say the best time to freeze eggs is anywhere between 32 to 37. Of course, 39 is still a good time. You don’t want to wait too, too, too long. The faster you could do it, the better.
Marianela Gille 31:47
For egg freezing, because you’re not trying to do the full embryo transfer and the whole process, you don’t need to go through all of the testing that we discussed.
In fact, I would just recommend at that point doing an ultrasound to take a look here. Let me pull it up here to make it easier.
An ultrasound to take a look at the general uterus, ovaries, do a follicle count, and to also do your blood work, the AMH. With that, it’s enough for us to get an idea of at least how many eggs we’re going to get.
And we can start making puns like, do you need one round? Do you need 2 rounds? And the reality is that we never know until we actually go through the process itself.

Another question. Can you tell me what the live birth rate success in your clinic for women over 40?
Live birth rate for women over 40. I don’t know the exact number over 40, but our live birth rate is about a 55%, which is considered to be even above the national average .So overall we do have really good pregnancy rates and really good like birth rates as well.
Marianela Gille 33:08
Next question, I’ve had most of the work up along with my husband. Age is 39 for me. I guess my question is, would IVF be the go plan as opposed to IUI due to age and quality? Sorry, long question. No apologies. This is a great question.
And I’m sure a lot of other women are in similar situations.
So it depends how long you’ve been trying. If you’ve been trying to get pregnant for three months and all of your workup looks generally good, your AMH is okay, and you’re thinking about having one to two babies, you could still consider IUI.
However, let’s suppose that all of your workup looks great. Your hormone level looks great. We assume you have a normal egg count, and we decide to go with IUI. If you get pregnant, what a blessing, right? That’s incredible, but it might take one, two, 3 rounds to get there. And then if you do get pregnant, you spend the whole next
nine months pregnant, a year and a few months recovering. So let’s say two years later at 41, you’re considering baby #2, especially if you’re considering baby #3 later on.
At that point, it may be a lot more difficult to get pregnant. So I would not encourage waiting too long to try or taking action with one route or another.
And I think your biggest question that you need to ask yourself is, do we want one child or do we want the possibility of creating two or three? If your answer is two or three, you’re probably leaning more towards IVF.
Next question I have here. I have an AMH level of 0.16 40 years old and my partner has low semen volume. What procedure would be the best for our situation and what are the chances of having a successful pregnancy? So with an AMH level of 0.16, that does put us in a little bit of a difficult situation.
Why? Because we know that there’s eggs there, but there’s not as many as we want to have. And then being at 40, we know that the quality may also not be great. So let’s say 50% of the eggs are of good quality, 50% may not be good quality. The next best step is definitely IVF, and it’s doing it sooner rather than later. And
also with the low semen analysis, right, the volume. If you start going through a cycles of IUI, your pregnancy rate is honestly going to be pretty low. In fact, I have a really good graph here I can pull up.
Marianela Gille 35:48
So, here’s a really good graph that shows the IUI success rates based on age.
We know that at the age of 40 years young, that’s the yellow line, with one round of IUI, the pregnancy rate is a 10%. Two rounds of IUI, that’s a 17%. Three rounds or more, it’s a 20%. With a low AMH, these numbers may actually be lower, maybe even half of that or lower than that.
So I would say your next best option is probably going to be IVF at this point.
Next question I have here. I have an AMH of 6.25. Are there challenges with high AMH? I’m not sure if ovulation is happening each month. Is IVF the best option for me? Great question. An AMH of 6.25 is considered to be really high. The age is also a factor, but even if you’re as young as 25 or 30 and you have an AMH of 6.25, there is a good chance that there is some component or a possibility of something called Polycystic Ovarian Syndrome, which has actually recently been renamed to Polys or Poly, I’m blanking on the word, but it’s PMOS and essentially it encompasses a lot more conditions that we know are associated with PCOS.
However, PCOS is a term that’s been used for a very long time, and polymetabolic endocrine.
So all in all, AMH of 6.25 can be an indicator of that. And if that’s the case, you may not be ovulating every month. And if you do end up going through an IUI or an IVF round…We know that in a patient with this high of an AMH or this many follicles, you actually may end up with a lot of the follicles being of bad quality.
I’ll give you a really good example. I have a patient with PCOS who recently had 50 follicles extracted and we ended up with 45 eggs. 45 eggs sounds incredible. Once you actually put the sperm, fertilize them and try to develop them, we only ended up with about 20 embryos, which 20 embryos is still a lot, don’t get me wrong, but you wouldn’t expect to have, or sorry, 20% of them that were of good quality to fertilize.
If I take another patient that has 20 follicles, which is a normal amount at that age,
and we do the same process, we’ll probably end up with the same amount of embryos. Why is that? Because even though there was a bunch of eggs, a lot of them may not have been of the best quality because there were so many.
So generally with PCOS, it has become more common now to recommend IVF as first line so that you don’t spend too much time going through multiple rounds of IUI.
and not being able to get to the goal of a healthy embryo that could create a healthy baby. Now, if you’re not sure if you’re ovulating, another option is to try taking medicine to help you ovulate and see if you’re able to get pregnant on your own. That usually can be done through your OB-GYN. They’ll give you a medication such as Clomid or letrozole that can help the body ovulate to see if you can try it naturally.
Next question? Yes. I had an ovarian drilling. What are success rates after that procedure? So we had a patient ask about ovarian drilling and what success rates are after that. The reality is it depends where you started from.
If your ovarian count was very low, if the age is above 40 and especially above 45, ovarian drilling may not necessarily make that big of a difference. There is a theory that the drilling itself will kind of stimulate the ovary to start producing more follicles or release more eggs.
But it’s really dependent on the whole history of a picture. I can’t say just in general.
Next question we have here. Male 40-year-old partner with AZFC deletion and female 35 years old, two children from a previous marriage. Unable to conceive after five years. Currently seeking fertility care and we would like three to four children, God willing. Partner also shows blood varicocele blockage. Is it okay to push the repair to repair the blockage with or after before M testing? Should egg retrieval be timed? Do you see more success? Also, I have an AMH of 0.9. Children are 16 and 9. Do you recommend twin transfer? Okay, let’s take this by parts because there’s a lot of really good questions here.
Anytime we have a male that has this specific deletion and we need to do a testing, I would say the goal is to try to get, and I’ll leave this to the urologist to make the call, because usually we’ll send you to a urologist to decide if they want to repair the varicoceal before or not.
Generally, they like to go forward with the testing, but if there’s a big degree of damage, or if they don’t think that they’re going to find a lot of sperm because of the miracle seal, they may repair it first.
Now, when should the egg retrieval be timed? We will work with timing the egg retrieval and the testing on the same day, ideally. There are some practices that will do the testing ahead of time and freeze the sperm. If possible, we generally try to get it done on the same day, just so that we have fresh egg and fresh sperm that same day.
Now, with an AMH of 0.9, do we recommend, or AMH of 0.9, do we recommend twin transfer? That is a great question. The answer is we do not recommend twin transfer. Why is that? I have a great slide here to show that.
While twins can sound really fun, the reality is that they can be very dangerous pregnancies, okay? And I can tell you that most women, by the time they get to our office and have never had children before, and they’ve been trying for three, five, or 10 years, they just want to grow their family.
And I can’t tell you how many requests we get for twin transfers or to try to create twins. And this is what I generally tell them. If nature gives us twins, we roll with it, but we shouldn’t be trying to go against nature and trying to create two babies at the same time.
There’s also the possibility when you transfer one embryo that it can split into two and give you twins. And again, if that happens, we go with it.
But if you transfer 2 and theoretically one of them splits or both of them splits, you can end up with triplets or with quadruplets. Let’s not even go to the extreme. Let’s focus on twins. This way here shows the increases of risk to the baby, to the mother, and to the family unit with twin pregnancies.
Risk to the baby. Mortality is five times higher in twins. Cerebral palsy, five times higher. Severe handicap, two times higher, and congenital anomalies, two times higher. Risk to the mom. Hypertension, preeclampsia, diabetes, anemia, bleeding, surgery risks. And family unit.
This one, a lot of people giggle, but it’s real, increased rates of divorce due to the strain on the relationship. One child is a lot of strain. You put two in there, and at the end of the day, it can cause a lot more issues. So again, if nature gives it to us, what a blessing, and we roll with it. But we shouldn’t be actively trying to create twins.
Next question: I’ve had two C-sections. Two C-sections makes it even riskier to put two babies in there, because at the end of the day, the uterus is going to have to expand more. If you do start having early contractions or going into preterm labor, that is very common with twins. That can make that previous C-section scar weaker and that can increase the risk of what’s called a uterine rupture, which can be very dangerous. So all in all, you definitely don’t want to be trying to create two at the same time.
Question from TikTok. Trying to conceive for four months, I’m overweight, otherwise normal cycles. DBT rises 4 DPO spot, 12 DPO progesterone didn’t help.
Marianela Gille 44:17
Okay, so there’s a question about being overweight and trying to conceive.
Being overweight, it depends how overweight we’re talking. If you’re just a few pounds above what’s considered to be a healthy weight for that age or for that BMI or for that body frame, it shouldn’t make a big difference if you’re having regular periods approximately once a month and if you’re checking for ovulation.
But if you start getting into a BMI range above…30, 35, and especially 40, that can make it a lot more difficult to conceive, like a lot more. Not to mention that it can, if you do get to the point of conception, then that can make it a very dangerous pregnancy as well. So we generally do recommend getting to a healthy weight before conception happens.
I’ve had three C-sections and my youngest is 15. Is pregnancy still risky?
Patient that had three previous D-sections and it’s been 15 years from the last one, they’re asking if it is still safe to get pregnant.
With every C-section, risks start going up. That’s the reality, right? So once you get to three C-sections, yes, it does become riskier no matter how much time has passed. Because at the end of the day, the uterus itself, yes, it’s healed itself, but there’s still scar tissue and there’s still an area where there may be some weakness
from the previous incisions.
If the question is, is it possible to get pregnant? Yes, absolutely. Is it risky? Depends. What you can always do is reach out to the last person who did your surgery and see if they can go through the operative report and note if there was any severe adhesions or scar tissue in the belly.
If there was a lot of adhesions when they did the third C-section, then that means that very likely there was more adhesions that formed and that can make it riskier for an additional pregnancy. If they tell you that everything looked really clear and healthy and there wasn’t a lot of scar tissue, then that already puts you in a better place. So all in all, it’s definitely worth having that conversation or trying to get the records from the doctor that last operated on you.
What are your thoughts on metformin to support weight loss during IVF? There’s a question about metformin use during IVF to support weight loss. Metformin itself actually has a lot of research that shows that when you have PCOS, we can actually end up with a better quality and quantity of eggs if we are on metformin. So all in all, I’m very much in favor. In fact, any of our patients that come in here that are diagnosed with PCOS or diabetes, we like to put them on metformin because we know we see good results. So I do encourage.
I have a question here. For egg freezing, do I need to remove my next one on birth control? My periods are semi-irregular about every 30 to 45 days. So not necessarily. It is still possible to do an egg freeze while keeping their birth control. If you’re not currently sexually active or you’re already coming up to the end of your next one on or you want a little break from the hormones, its not a bad idea to remove it, do the egg freeze, and then get a new one.
But if you’re a year into your next one on, you really like it, you’re sexually active, you’re at risk of pregnancy, and you’re not ready for it right now, it’s better to not remove it.
Question? I have one here. I had weight loss surgery in September. I’m still above the recommended BMI. Do I need to wait to be post-op one year to begin IVF? And what BMI do you all require here? I know you mentioned recommended, but what is the highest you will work with? Okay, so regarding BMI, we generally like to wait a year after the surgery just to make sure that you’re not actively losing weight rapidly when you’re doing the process of the transfer itself.
Why is that? Because if you’re losing weight as our little embryo is trying to get nutrients, then that can cause some risk to the embryo itself.
Now, our BMI cutoff here to do IVF is a BMI of 45. That does not mean that we do not see you until, oh, sorry, of 40. That does not mean that we don’t see you if your BMI is above 40. We absolutely will see you. And we actually have a program here that’s called Fertility Fit. And for our patients that come in and are eager to get started and have a BMI above 40 and want to lose weight, we help them with trizepatide to see if we could try to get them down to the goal BMI so that we can get started with the IVF treatment as soon as possible.
And if we’re not ready necessarily to do the transfer at that point, It’s still a good option to start creating the embryos again, because younger eggs are going to form better embryos. And then in the future, once they’re ready to do the transfer, then we can go ahead and get them placed.
Well, question is, what is your opinion about DNA fragmentation? Opinion about DNA fragmentation. So DNA fragmentation is a test done on the semen, so it can determine if there is a lot of issues with the sperm itself. And it used to be really common because with the DNA fragmentation, they were trying to determine more than anything, does this patient need a process called ICSI or not? Okay. And at the end of the day, we do ICSI on all of our patients.
Why is that? Because if we didn’t do the ICSI, and the eggs didn’t fertilize, then that’s a lot of a process to go through for you to not end up with what you’re hoping to get to. So if in general in medicine, this is not just for DNA frag, but any test that you’re going to do needs to give you some guidance of what is the best next step.
If that test is not going to change the outcome, we do not recommend doing that test. And in general, the DNA fragmentation isn’t going to change the way that we practice medicine. We’re still going to take the sperm. We’re still going to put them through a filter to make sure that we get the best swimmers. And we’re still going to only transfer the sperm into the egg that we look, that looks healthy and that looks like it’s going to be viable.
The DNA frag test is not really going to change the outcome. So we wouldn’t want you to do a test that you’re going to spend time, money, energy, and paying for. That’s not going to really change the outcome.
Next question I see here. Can you be on tirzepatide GLP-1 during egg freezing or IVF? So generally we like to stop the tirzepatide 2 weeks before the egg retrieval. Why is that? Because we need your bodies to kind of wear it off a little bit before we’re putting you through some of the anesthesia medications.
If you’re not ready to transfer right away, then you can go ahead and get back on the tirzepatide the following week until you’re ready to do the transfer. If you’re trying to do that embryo transfer right away, it’s better to stay off the tirzepatide because we want you off the medication two months before you’re doing the embryo transfer.
Why is that? Same concept as the one that we talked about with the weight loss surgery. You don’t want to actively be losing weight when you’re starting a pregnancy, okay?
We’ll usually guide you until you when to stop it because we do have a lot of our patients that are on tirzepatide and we’ll tell them exactly when to stop it so we could start the stimulation medication and then bring them in for the procedure.
Yeah.
Do you recommend the Full Well Women’s Fertility Trio Vitamins while preparing for IVF?
Someone’s asking if I recommend the Full Well Women’s Trio vitamins. I don’t know that specific vitamin itself, but the general vitamin combo that we recommend is a prenatal vitamin. A question I do get a lot is, Dr. Gille, tell me exactly which one to buy. What is the best brand? There’s no best brand of vitamins.
The reality is that a lot of companies have put really nice marketing into some of the prenatal vitamins and driven up the cost and charge you twice as much for the same thing that you’re going to get from an HEB brand vitamin. So I generally recommend get a normal store-bought regular brand or Ritual is one of the fancier ones, but that’s if you really want to try something a little more natural. Nature Made is generally my go-to. Simple and straightforward, it has everything that you need, and it’s not going to break the bank.
I think we’re almost on time. We have time for maybe another two to three questions.
I cut my tubes 2 years ago and I want another baby next year. What is my best option? This is someone who had her tubes tied two years ago and she wants another baby and is asking what’s the best next step.
So if you think you’re going to want to have another baby anytime, whether it be now, a year or three years from now, the best thing to do is to start the IVF process so that you can create the embryos. Once you create the embryos, those are going to be in storage. And whether you choose to transfer them in six months, a year, or three years, you’re going to have a way better outcome than if you wait an entire year and then try to start creating embryos at that point. It’s also very age-based. If you’re 25 and you’re thinking about waiting until the age of 26, maybe not that big of a difference.
But if you’re 36 and thinking about waiting until the age of 37, one year, one year in your mid to upper 30s can start making a much bigger difference. So I definitely recommend start first with the egg freezing process. Leave them frozen, give yourself peace of mind, and when you’re ready, you just transfer the embryo.
Ligia Popescu 54:17
Nice.
Marianela Gille 54:19
How come I went through IVF for my first, then got pregnant naturally for my second, and now I’m trying for my third with IVF? So someone’s asking how come the first time they got pregnant they had to go through IVF, second time spontaneously got pregnant, and now they’re trying again for a third and they’re needing IVF again.
The reality is that no one can tell you you’re completely infertile, right? There’s…
many reasons as to why the pregnancy didn’t happen on its own the first time. We don’t know what it was. And the reality is that if you continue to try and wait, maybe you would have gotten there on your own, but maybe you wouldn’t have.
And it would have been another three years or four years, and that would have gotten you further away from your big picture, which is creating your family of these three children.
So all in all, IVF is for the moment that you’re ready to move forward. It’s not happening on its own. And it feels like it’s the right next step. And that’s what you and your doctor come up with. Do couples conceive naturally after IVF? Yes. I don’t see it all the time, but I do see it quite frequently.
I used to actually deliver babies a few years ago and those IVF babies, the moms would be like, I don’t need birth control. I did IVF. And I was like, you do need birth control because even though you think it can happen, there is a possibility. And I don’t know, every six months I would get one that would come and be like, yep, pregnant again. And it was only three months later and that wasn’t the plan.
So it could be also that through pregnancy, there’s hormonal shifts, your body shifts, the uterus shifts. It’s hard to say exactly what helped it happen that second time. But if you’re now trying for a third and it’s been some time and you still haven’t gotten to your goal, then yes, IVF is probably going to be your next best step.
A question here, is the price of surrogacy the same as IVF or more pricey? So the price of surrogacy is actually a lot more than IVF. Why? Because logistically, it’s a lot harder to coordinate, right? You have to plan that another person is going to be carrying this child. So there’s a lot of additional screening and process that
goes into having one person carry the baby of another person.
In fact, it’s a process that is so complex that we actually don’t offer it here at Pozitivf. Part of our services here is providing lower costs or more affordable fertility services. And once you start getting surrogacy involved, that involves lawyers, a lot of paperwork, a lot of clearance, and that can actually drag out the process and start getting the cost close to about 100,000, if not more. Whereas IVF is something that costs about 15 to 20,000, depending what you’re going for. So yes, it’s a lot more pricing.
It’s definitely something worth looking into if you cannot carry the child or if it’s not an option for you to be pregnant.
Okay, next question is, AMH is 0.03. My vitamin D is 26. Would including a D supplement help if I am about to start the IVF process? Not necessarily. The AMH itself is produced by the follicles in your ovary. So no matter how many supplements, vitamins you take.
In reality, there’s only one supplement that maybe has a very small chance of helping, which is the CoQ10. Your vitamin D level is a little bit low, right? 26 is below the standard. We like to see it at about 30 or above, but you’re not alone. I would say most women are probably around that range.
So increasing your vitamin D level is going to be better for the process of conception. I don’t think it’s necessarily going to make a big difference when it comes to changing your AMH or the quantity or quality of the egg itself.
Quite another question similar in the similar ballpark is can you increase your AMH? AMH in theory cannot be increased. There’s A caveat though. There’s many patients that will do, let’s say an AMH every six months just to see where it’s at. And they’ll see it drop a little and then sometimes it goes up a little and then it drops again.
The reality is that it shouldn’t fluctuate greatly, and it’s not always going to be the same number or dropping perfectly. But in theory, you cannot necessarily create more eggs, right? The eggs that you have were given to you by your mother when you were in her womb. So no matter what supplements, treatments, or products are offered out there…There’s nothing that can create new eggs at this point.
Ligia Popescu 59:01
So I think we need to pull up the closing slides. And yeah, we’re almost there. It was an exciting presentation. I loved all the questions.
Marianela Gille 59:06
Oh, sorry, yes.
Sorry, yes, let me pull it up here. I love answering questions, so I can keep going, but…
Let me see where we have it.
Let me find the slide.
Ligia Popescu 59:22
Thank you.
What I’m going to do right now is invite this audience to please join us again next Monday for our second installment, where we will be on the topic of IVF versus other options with Dr. Jaye Adams, another REI from Pozitivf fertility. So I’m going to put that information here.
Ligia Popescu 59:47
And then I also want to just share the contact information for Pozitivf. If anybody is interested in, you know, scheduling an appointment, you can go to, I’ll put this website in the chat. This is the link: pozitivf.com
And yes, so they’ve got many, many locations. So please give us a call. We’d love to have you come in and schedule your first appointment or your new patient appointment, whatever it is, we are going to respond to your questions. I’ll get a recording out to everyone.
Thank you for joining us. It was a really great time. Thank you so much, Dr. Gille, for joining us. Appreciate it.
Marianela Gille 1:00:32
Thank you so much everybody for taking the time to join us tonight
Ligia Popescu 1:00:33
Thank you.
Live Audience Questions and Answers
1. Are both the saline infusion sonogram and HyFoSy required?
Yes. Dr. Gille recommended assessing both the uterine cavity and the fallopian tubes so patients have the full picture before deciding on treatment such as IUI or IVF.
2. Is unexplained infertility diagnosed before a laparoscopy?
Yes. If the standard workup looks normal and there are no signs or symptoms of conditions such as endometriosis, unexplained infertility can be diagnosed without a laparoscopy.
3. If all initial tests come back normal, does that mean nothing is wrong?
Not necessarily. Standard tests look at the big picture, but they may not show microscopic issues affecting fertilization, embryo development, or implantation.
4. I have an endometrioma and kissing ovaries. Would laparoscopy be next?
It depends. Surgery may help in some cases, but it can also affect ovarian tissue and egg reserve, so the decision should be individualized and made with an experienced endometriosis surgeon.
5. What if a semen analysis is abnormal?
The next step depends on the abnormality. IUI may help with some concentration or motility issues, while IVF with ICSI may be recommended for severe count, motility, or morphology concerns.
6. With endometriosis, is suppression before IVF/FET recommended?
Not always. Suppression may be considered for more severe endometriosis, significant symptoms, or limited embryos, but many patients can proceed without suppression.
7. After a timed intercourse procedure with an HCG trigger shot, when can I take a pregnancy test?
Dr. Gille suggested testing around the time the next period is expected; some positives may appear around 11 days after the shot.
8. I lost one tube due to an ectopic pregnancy and the other has a distal tubal blockage. Do I need IVF?
Yes, IVF was recommended as the best next step because the tubes are damaged or absent, making it very difficult for sperm and egg to meet naturally.
9. Will I need medication if I already ovulate?
For timed intercourse, medication may not be needed if ovulation is regular. For IUI, medication is often recommended to improve the chance of ovulation during that cycle. IVF generally requires medication.
10. I’m 39 and not ready for a baby. Should I freeze eggs now or wait and try IVF later?
Dr. Gille strongly encouraged freezing eggs sooner because egg quality declines with age, especially after 40. Testing for egg freezing usually includes an ultrasound, follicle count, and AMH bloodwork.
11. What is the live birth success rate for women over 40 at the clinic?
Dr. Gille did not provide an exact number for women over 40, but stated the clinic’s overall live birth rate is about 55%.
12. At age 39, is IVF a better plan than IUI because of age and egg quality?
It depends on how long the patient has been trying, test results, and family goals. If the goal is more than one child, IVF may be favored because it can create embryos now for future use.
13. With AMH 0.16 at age 40 and low semen volume, what is the best procedure?
IVF was recommended sooner rather than later because both egg reserve and sperm factors may lower the chance of success with IUI.
14. Are there challenges with a high AMH, such as 6.25, and is IVF best?
A high AMH can be associated with PCOS or ovulation issues. IVF is often considered, but ovulation-induction medication with an OB-GYN may also be an option if ovulation is the main concern.
15. What are success rates after ovarian drilling?
Success depends on the patient’s overall history, age, and ovarian reserve. Dr. Gille could not give a general rate without that context.
16. With male AZFc deletion, varicocele, and AMH 0.9, how should sperm testing and egg retrieval be timed?
Dr. Gille recommended involving a urologist. Ideally, sperm retrieval/testing and egg retrieval are timed on the same day when possible, though some practices retrieve and freeze sperm beforehand.
17. Do you recommend twin transfer?
No. Dr. Gille discouraged intentionally trying for twins because twin pregnancies carry higher risks for the babies, the mother, and the family.
18. After two C-sections, is twin pregnancy riskier?
Yes. Prior C-sections can increase risk, and twin pregnancy can further raise concerns such as preterm labor and uterine rupture.
19. If I’m overweight but have normal cycles, can I still conceive?
It depends on the degree of excess weight. Higher BMI ranges can make conception more difficult and can increase pregnancy risks, so achieving a healthier weight is generally recommended.
20. After three C-sections, is pregnancy still risky if the youngest child is 15?
Yes, risk can still increase with each C-section regardless of time passed. Reviewing the prior operative report may help assess scar tissue and adhesions.
21. What are your thoughts on metformin for weight loss support during IVF?
Dr. Gille supports metformin use in patients with PCOS or diabetes because it may improve egg quality and quantity in that context.
22. For egg freezing, do I need to remove my Nexplanon birth control?
Not necessarily. Egg freezing may still be possible while keeping it in place, especially if the patient is sexually active and pregnancy prevention is important.
23. After weight loss surgery, do I need to wait one year before IVF, and what BMI is required?
The clinic generally prefers waiting about one year after surgery before transfer if weight loss is still rapid. Dr. Gille stated the clinic’s IVF BMI cutoff is 40, while also noting they see patients above that BMI and may help with weight-loss support.
24. What is your opinion about DNA fragmentation testing?
Dr. Gille said DNA fragmentation testing usually does not change their treatment approach because the clinic performs ICSI for IVF patients and selects the best-appearing sperm.
25. Can someone be on tirzepatide or a GLP-1 during egg freezing or IVF?
Dr. Gille said tirzepatide is generally stopped two weeks before egg retrieval and should be stopped about two months before embryo transfer.
26. Do you recommend FullWell Women’s Fertility Trio vitamins while preparing for IVF?
Dr. Gille was not familiar with that specific product and recommended a standard prenatal vitamin, noting that no brand is necessarily best.
27. I had my tubes tied two years ago and want another baby next year. What is my best option?
IVF was recommended, especially if the patient wants to create embryos now and transfer later. Timing depends heavily on age.
28. Why did I need IVF for my first child, conceive naturally for my second, and now need IVF again for a third?
Dr. Gille explained that fertility can vary over time. Natural conception after IVF can happen, but if pregnancy is not happening now, IVF may again be the best next step.
29. Is surrogacy the same price as IVF?
No. Surrogacy is typically much more expensive because it involves additional screening, legal work, coordination, and logistics.
30. With AMH 0.03 and vitamin D of 26, would vitamin D supplementation help before IVF?
Vitamin D supplementation may support overall conception health, but it is unlikely to increase AMH or change egg quantity or quality.
31. Can AMH be increased?
In theory, no. AMH may fluctuate slightly between tests, but supplements or treatments cannot create new eggs.

Hello, everyone. Welcome to the second of seven fertility awareness and education life webinars brought to you by Positive Fertility. Today, we will be talking about IVF versus other options. And with us is Dr. Jay Adams. She is an REI with Pozitivf Fertility.
Thank you all so much for sharing your evening with us and tuning in today.
We’re going to go to the next slide and take a look quickly at the agenda for today. We do have a set time set aside for question and answers, but feel free to ask questions anytime through the Q&A or the chat.
Audience members’ information is completely hidden, so your questions will be anonymous. We will be providing a recording of this presentation afterwards. If you have any questions at all, please feel free to e-mail me directly. I’m going to put my e-mail in the chat here in a moment.
But I just want to encourage you to use those audience reactions. We love to see those stars and hearts and claps. And please be willing to ask any questions. We’re ready to talk to you. So last week we talked about the first step in a fertility clinic. And today we’re going to talk a little bit more about the baseline of a lot of people’s anxieties when they think about walking in a fertility clinic. And that is navigating IVF versus all the other options available. So Dr. J, I’m going to turn it over to you. Could you please just tell us a little bit about yourself?
Jaye Adams 1:57
Thanks so much. Thanks so much, Ligia. I’m excited to be here today with our patients and our audience. I practiced as an OB-GYN for about 12 years before switching to reproductive endocrinology and infertility. And now I’ve been doing just fertility care for another 14 years.
Good grief, that sounds so long. I love what I do. I love helping couples build their family and I love the positive team. My husband and I are blessed with three young adult children that we might not have if it were not for the miracle of IVF for us. And by the way, we also did do ovulation induction with timed intercourse and IUI before we moved on to IBS.
Today, we’re going to break down a massive myth, the fear that walking into a fertility clinic means that you’re immediately forced into expensive, high-tech IVF treatments. That couldn’t be farther from the truth. When a patient walks through our doors at Pozitivf, our primary goal isn’t to sell a specific treatment, it’s to find answers.
We look at diagnostic testing as a diagnostic puzzle, not a predetermined ticket to the operating room. IVF is a phenomenal tool. It’s revolutionary, but it’s far from the only tool that we have.
I want you to shift your mindset. Fertility care is a ladder and not a single cliff. At the base of this ladder, we have what we call low-tech interventions. This includes timed intercourse combined with simple ovulation induction medications, medications like letrozole or clomiphene or clomid. These are inexpensive oral medications that help ensure a healthy egg is released at the same time.
Many patients achieve successful pregnancies right here at that very bottom of the ladder with minimal clinical intervention, no surgery, and very little stress on their daily schedules. Let’s look at level one. Ovulation induction combined with timed intercourse. For patients who have irregular cycles or who struggle to track their ovulation, this is an incredibly powerful first step.
We utilize these gentle oral medications, take them for just five days at the start of your cycle. These medications encourage your body to mature a healthy follicle. We pair this with light clinical monitoring like a quick ultrasound to identify when the follicle is ready. You may be able to detect ovulation on your own at home with ovulation predictor kits, or we can also have you take a trigger shot to time and ensure ovulation occurs. We then guide you on precisely when to have intercourse at home to maximize your natural success rate. It requires no surgery, minimal clinical visits, and is non-invasive. If we need to take the next step up, we move to level 2, intrauterine insemination, or IUI. I like to describe IUI as giving nature a well-timed head start. On the day of your ovulation, your partner or a donor provides a semen sample, or if you have frozen donor sperm, we can use that too. Our laboratory team then washes and prepares this sample, filtering out the immodal sperm, debris, cellular waste, and isolate a highly concentrated pool of the healthiest, most active sperm. Using a very thin, flexible catheter, we gently guide this sample directly into the uterus. The procedure is usually painless, takes about 5 minutes in an examination room, and requires absolutely no sedation. It cuts down the physical distance the sperm has to travel to meet the egg, giving you a clear and clinical boost.
IUI is an incredible tool, but it is highly diagnostic dependent. Who benefits the most from this level of care? First, unexplained infertility. When standard hormonal panels, semen analysis, and anatomy scans show that everything’s normal, but conception is still delayed, IUI is a logical low-stress starting point.
Second, mild male factor infertility. If there are slight compromises in sperm count or speed, our laboratory washing process maximizes the useful part of the sperm, giving those sperm a big head start. IUI is also an excellent treatment for male factor that involves problems with having intercourse.
Sometimes for medical reasons, having intercourse can be difficult for some couples or are hard to time. IUI can bypass some of these issues. For couples with geographic separation, it can also be combined with frozen sperm to allow conception efforts when the male partner cannot be present during the woman’s fertile window.
Third, in the setting of using donor sperm or other cervical factors, IUI is the gold standard, really baseline for single parents by choice or LGBTQ couples using donor sperm. It’s also ideal for bypassing any cervical scarring or hostile cervical mucus that might block natural travel.
Additionally, IUI is a nice boost to couples undergoing ovulation induction for PCOS, which is now PMOS, or ovulatory dysfunction. It’s often added to those ovulation induction cycles when ovulation induction alone has not yet resulted in a pregnancy.
Now let’s talk about level 3. When is IVF needed? While we always try to find the lowest rung on the ladder, there are times when bypassing the lower rungs is medically necessary or statistically smarter. IVF is an advanced care pathway where we retrieve mature eggs directly from the ovaries. We fertilize them with sperm inside our embryology laboratory.
We recommend IVF when there are absolute physical barriers, such as bilaterally blocked fallopian tubes, severe pelvic scarring, endometriosis, or severe male factor infertility or sperm counts are too low to succeed with IUI. IVF is also necessary when couples are planning embryo testing for chromosomes or for other genetic reasons and it’s highly recommended when lower tech treatments haven’t yet yielded success after a few attempts.
The reason IVF is so revolutionary comes down to the sheer level of scientific control and analysis it provides. First, bypassing physiological hurdles. Because fertilization happens in our state-of-the-art lab incubator, we bypass tubular damage, sperm-egg interaction concerns, pelvic inflammation, and cervical barriers completely.
Second, genetic screening or PGTA, pre-implantation genetic testing for aneuploidy. Before we can transfer, before we transfer an embryo back to the uterus, we have the ability to perform highly accurate chromosomal screening. This allows us to select embryos with the correct number of chromosomes, which may decrease miscarriage rates and increase the pregnancy rate per transfer by selecting the embryos most likely to be able to yield a pregnancy.
Third, preserving fertility, IVF allows us to freeze healthy embryos. This essentially pauses the biological age of those embryos, allowing you to build your family sequentially over several years, possibly extending your reproductive window for further family building later on.
And 4th, unparalleled efficiency. While IUI requires patience in multiple cycles, IVF does in fact yield the highest success probability per individual attempt.
Ligia Popescu 9:22
We have a question real quick. Is there generally a certain amount of times the IUI may have failed before you consider moving to IVF?
Jaye Adams 9:22
Ah, that’s a very, a very good question, Ligia. So that will differ per couple. We usually think that we’re going to max out our IUI cumulative success rate around three or four cycles of IUI. And doing the 6th, 7th, and 8th cycle of IUI, where those may yield additional pregnancies, the additional cumulative yield is pretty low. Most couples after two or three will consider moving to IVF depending on their level of patience, their age, financial resources.
Ligia Popescu 10:14
Absolutely.
Jaye Adams 10:15
Okay, let’s look directly at the data, because transparent expectations are key to a healthy fertility journey. On this chart, you can see that the average pregnancy success rates per single clinical cycle for patients under age 35. Keep that in mind, these numbers vary depending on the age of the woman in the couple. Natural timed intercourse or simple ovulation induction hovers around 5 to 10% per cycle.
Moving up to IUI boosts that rate to around 10 to 15% per cycle. IVF, however, jumps the success rate up to 55% or higher per individual cycle when taken into account the cumulative effect of transferring all available embryos that are usable.
There’s a question from TikTok Live. It says, my first IUI cycle ended in a miscarriage. So right now I’m 40 years old. Is it reasonable to go straight to IVF?
I’m so sorry for your loss. I know that must be heartbreaking for you. Being at age 40 is definitely makes these decisions a little bit tougher. You did get pregnant on your first IUI. The odds of getting pregnant again on an IUI at some future time are pretty good when that’s worked once.
However, even six months of chronological time could be a factor for you in your family building goals. And so I don’t know that I would spend too long doing multiple IUIs at age 40.
Another thing to consider is if you’re wanting more than one additional pregnancy, again, banking those embryos now may allow you the chance for not only a successful pregnancy now at 40, but maybe frozen embryo transfer at 42 and maybe another one at 44, depending on your family building goals.
One other question. We have 12 donor eggs from a 24 year old and my husband has excellent sperm. How many do you expect should I do PGTA?
So actually the guidelines are pretty clear on donor egg cycles. American Society of Reproductive Medicine actually does not recommend that PGTA is cost effective when using donor eggs. For a donor age 24, the euploid rate will be very high, maybe as high as 70% or a little bit higher.
And when you factor in the cost of donor egg, it’s probably most efficient to go ahead and use those embryos without testing. However, if you want to test them, I think that’s a very personal decision. Probably the majority will be euploid, certainly not every single one of them. So you may be able to filter out a couple of embryos that aren’t normal if you choose to test.
Okay, let’s see. Okay, I think we were talking a little bit about the success rate for these different treatments and keep in mind that while ovulation or 10 to 15 percent for IUI sounds pretty low, it is a highly repeatable low-cost procedure.
And you could try several rounds, again, two, three, maybe 4, for a fraction of the cost and for potentially a lower physical toll than a single IVF cycle. Remember, this is a marathon and not a sprint, as we all know on this journey. To help you weigh these decisions, we use this simple framework comparing invasiveness against investment.
With timed intercourse, your financial investment is minimal and the physical invasiveness is virtually 0, barring the ultrasounds.
But the timeline might be longer and the success rate is lower. With IUI, you have a moderate financial investment, usually around 1000 to 2500 per cycle, with a fairly low physical toll.
With IVF, the financial investment, of course, is much higher, typically 10 to 15,000 or more, depending on the medications and your choice about genetic testing. And the physical toll includes daily injections for 8 to 12 days and a sedated egg retrieval that requires some anesthesia. But you are investing in the absolute highest chance
of immediate success. There’s no wrong answer here. It’s about finding the balance between time, budget, and the emotional bandwidth that works for you.
I want to close the presentation with a quote that I share with every single one of my patients. Our goal is always to find the lowest rung on the ladder that safely get to a healthy baby. And if we can help, you can see with a simple $100 worth of medication and timed intercourse, that is a massive victory for us.
If we need to use IUI, wonderful. If we need the power of IVF, we have a world-class lab ready to support you. You should never feel pressured into a treatment that you’re not ready for. You’re the driver of your care pathway. You are in the driver’s seat. A good clinic, a good physician outlines the entire ladder for you transparently, showing you the pros, the cons, the costs, and the statistical odds, and then lets you
decide where you feel comfortable starting. And with that, I want to hand it back to Ligia so we can jump right into your questions.
Ligia Popescu 15:35
Thank you. So I’ve got another question here from the audience. My partner and I are dealing with male factor infertility, low sperm count. Is IUI even an option for us or do we go straight to IVF?
Jaye Adams 15:51
Ah, the short answer, it depends upon the degree of the low sperm count. Remember how I mentioned that we wash the sperm for an ideal IUI? During that wash process, we isolate the moving sperm. For an IUI to have the best chance of success, we generally want to see at least 10 million moving sperm after the wash is complete.
And 5 to 10 million motile sperm is reasonable for a couple in which the woman’s very young and their fertility has not been longstanding. If the count is slightly low, IUI is still a great cost-effective first option. However, if the count is very low, less than 5 million total motile or severely low, less than 1 million total motile sperm, IUI successes are pretty low. And in those more severe cases, we recommend IVF combined with ICSI. That’s where we inject a single sperm into an egg. And our embryologist manually selects the single modal normal looking sperm and puts it directly into the egg. This saves you time and heartbreak.
Ligia Popescu 16:54
You mentioned something about 8 injections with the IVF. So this audience question is related to that. I’m anxious about the injections. Can you talk about the difference in physical toll and medication protocols between an IUI and an IVF cycle?
Jaye Adams 17:11
That anxiety is completely valid. Needles are a major hurdle for many people. The physical difference between the two is night and day. An IUI cycle is pretty low intensity. It usually involves, as we mentioned, taking oral medications like Letrozole or Clomid for five days, one or two quick ultrasound checks.
And on occasion, a single trigger shot, which is a subcutaneous injection, can be given to lock in the ovulation timing. IVF, on the other hand, is a more intensive multi-week process. You’re looking at 8 to 12 days of injections, sometimes twice a day, at least once a day and sometimes twice a day.
These hormonal injections stimulate your ovaries to grow multiple eggs instead of just one, and it requires frequent clinic visits every two to three days for ultrasounds and sometimes blood work, culminating in the surgical egg retrieval under moderate sedation. So yes, IVF is significantly more physically demanding, which is why we love utilizing the lower rungs of the ladder whenever they’re clinically appropriate.
Yeah, I have a question from TikTok. After a loss, when is a good time to try again? Yeah, I think the answer to that question will vary a little bit on the details of the loss and how far along you were at the loss. Most losses occur in the first trimester. And typically, we will wait until the pregnancy has passed.
And usually release couples to begin attempting pregnancy again after the next spontaneous normal menstrual cycle after the loss has resolved.
So typically waiting just the interval from the loss until the next normal menses is enough. There was some older guidance when I was training that you had to wait two or three months before you could begin trying again, that the risk of a second loss might be higher if you conceived the next cycle. But in fact, that hasn’t been proven. And the rate of a second loss is not any higher if you conceive on the first cycle after loss versus 3 cycles later.
Emotionally, some couples need a little more time to process before they’re ready to jump right back and try again. So again, it would be a very personalized decision. Additionally, second trimester losses, sometimes there is some advice to wait a little bit longer for the uterus to fully involute and for you to recover from that more taxing physical experience.
Ligia Popescu 19:56
Sure. One more question here. My partner and I were diagnosed with unexplained infertility. Everything looks normal on paper, but we’re just not getting pregnant. Where do we even start on the fertility care ladder for that?
Jaye Adams 20:12
Unexplained infertility is incredibly frustrating because you don’t have a clear target to hit, but it’s actually very common. Probably 10% of couples that receive a full array of diagnostic testing will be diagnosed with unexplained infertility. About half of those couples that are unexplained may have an anatomic finding such as endometriosis or maltubal disease if they went to a surgical evaluation with laparoscopy.
However, in our modern day, we don’t recommend that laparoscopy is necessary as a diagnostic maneuver in these situations because the treatments have the same success rate moving forward, and it doesn’t really change what we offer the patients for treatment for unexplained.
For unexplained, the typical lesser before greater protocol is to start with three cycles of medicated IUI. And even though your testing looks normal, the oral medications give you a super ovulation boost. Maybe you get to release two healthy eggs instead of 1, and IUI bypasses any unseen cervical mucus barriers while timing the sperm delivery.
If those two to three cycles don’t work, it usually points to a subtle issue that standard testing can’t see, like egg sperm binding or functional tubal factor or pelvic adhesions or endometriosis or an embryo development problem. At that stage, moving to IVF serves as both a treatment and a diagnostic tool, because it lets us witness fertilization happening in real time. In truly unexplained subfertility, conception rates hover around 2% per cycle. They’re not zero, they’re just very, very low compared to what we expect.
An older but very classic study suggested that if you just add superovulation to those couples with unexplained subfertility, you might increase that conception rate to about 4% per cycle. Just adding IUI may also increase the pregnancy rate from 2% to 4%. When both superovulation and IUI were added in cases of unexplained subfertility, the pregnancy rate increased about fourfold from 2% overall to about 8 to 10%. per cycle. And that’s why this treatment is often recommended for unexplained infertility, because it may be helpful even when we’re not sure why pregnancy hasn’t occurred on its own yet.
Ligia Popescu 22:27
Great. So if IUI is so much cheaper, but it has a lower success rate, is it actually better financially to go straight to IVF or could you, because with one IVF, you could get 3 IUIs. So how do I make the decision on which?
Jaye Adams 22:49
I appreciate you bringing this up. We have to be realistic about financial considerations because financial stress is important and it impacts fertility stress. The math works out a little bit differently for everyone, but here is one way to look at it.
An IUI cycle is a fraction of the cost of IVF, often roughly 20% of that cost. If you do 3 cycles of IUI, you’re spending quite a bit less to give yourself a cumulative 30% chance of success. For many families, that’s highly accessible and a worthwhile gamble before taking on the large financial burden of IBF.
However, if you have fertility factors like damaged tube, very low sperm counts, severe endometriosis, or if female age is a concern where IUI success rates drop to much lower, say less than 5% per cycle, then repeating IUIs may not be an effective use of financial resources. And in those cases, saving your capital for the higher success rate of IVF is a smarter financial play. We always map out these exact financial math scenarios with you during your financial consultation.
Ligia Popescu 23:56
Another question. I’m terrified of having triplets or high order multiples. Doesn’t fertility treatment drastically increase the risk of multiples or is that risk higher with IUI or IVF?
Jaye Adams 24:11
This is a common fear, largely left over from the 1980s and 1990s Optimum era. Today, the reality might surprise you. Your risk of higher order multiples is actually higher with IUI than it is with modern IVF. And this is why, in an IUI cycle, if you take oral medication and mature three or four eggs, once we inseminate with sperm, we can’t control how many of those eggs fertilize.
If you release 3 eggs, you could theoretically have triplets. We do monitor you closely in this cycle and will sometimes recommend to cancel if too many eggs mature, but there’s still a risk. With modern IVF, we have a lot more control. Once we extract the eggs, fertilize them, and under modern guidelines, we almost always prefer what’s called a single embryo transfer, replacing just one embryo into the uterus at a time and storing or freezing extra embryos for later. An embryo might split into a twin gestation after transfer, but this is a very rare event, about 2% overall.
So the risk of higher order multiple rate is actually pretty close to 0, making IVF the safest choice if your goal is strictly one healthy baby at a time.
Ligia Popescu 25:25
Gotcha. Two more questions here. We’ve been trying timed intercourse with ovulation strips at home for a year, and it’s completely destroying our intimacy and mental health. Will moving to a clinic just make it feel even more clinical?
Jaye Adams 25:41
What you’re describing is incredibly common. We call it timed intercourse burnout. Trying to schedule your intimacy around the plastic stick every month turns a beautiful thing into a stressful chore. When you move to a clinic for something like IUI, yes, while it’s medicalized, it actually relieves the specific relationship burden.
We take over the tracking, the timing, the logistics. We tell you what day to show up. We handle the placement of the sperm. We take the pressure away from your bedroom. Many couples tell me that moving to IUI actually restored their relationship because sex could go back to just being an expression of love while the clinic took care of the baby making part of the science.
Ligia Popescu 26:24
Got it. Go ahead.
Jaye Adams 26:24. I have a question here from TikTok. It says, I’m 51 years old. I want to have a baby. What are my options?Thank you for that question.
So while people at 51 can and sometimes do get pregnant with their own eggs, it is extraordinarily rare. The main option for someone seeking to carry a baby at 51 involves using donor egg or potentially donor embryo.
And in some clinics, there’s an age limit for transfer of an embryo and occasionally even moving to a gestational carrier or surrogate for the safety of the pregnancy, depending on your health and the age limit for the clinic.
Ligia Popescu 27:15
So one last question. Before we even try the first rung of the ladder, how can lifestyle changes like diet or quitting vaping or supplements improve our chances to or of avoiding IVF?
Jaye Adams 27:33
Lifestyle changes are the foundational soil that the ladder stands on. They matter immensely, particularly for egg and sperm quality. While damage to eggs is not reversible, new sperm can develop in about 90 days. So making changes is particularly helpful for men and making changes for women to prevent any additional cumulative damage to their eggs is also very helpful
Cutting out toxins, most notably smoking and vaping, along with decreasing alcohol consumption is strongly recommended. Managing possible metabolic or inflammatory health concerns through diet changes, regular exercise, good sleep, which is more important than we realize, and possibly antioxidant supplements is also a good idea for general fertility. Particularly for very overweight couples, major changes in weight loss and health status can truly improve their semen analysis or ovulatory health into a range where natural conception or simple IUI becomes highly successful, allowing them to bypass IVF entirely.
Sometimes we have patients make overhauls in their diet, exercise, and lose a lot of weight and they get pregnant on their own before they can come back to seek fertility care with us because of these changes. So it’s why we always address lifestyle and wellness at the exact same time that we map out your medical.
Ligia Popescu 28:44
Yeah.
Another question from TikTokHow, What are the chances of having twins with donor eggs?
Well, fair question. So the chances of twins with donor eggs when we’re transferring a single embryo should be the same as the chances of twins if you’re using autologous eggs from the woman involved in the sense that if we’re transferring 1 embryo, regardless of the egg source.
The guidelines for donor egg transfer are fairly strict for the American Society of Reproductive Medicine. And because we follow age-related guidelines, at least in regards to female age. The younger a woman is when her embryos are created, the stronger the guidelines for transferring just one embryo at a time. So even if a woman is 43, if the embryo came from a donor egg source and the donor was 24, those guidelines would go towards her, that we would transfer one at a time, again, to maximize the chance of a single live birth and avoid a risky twin pregnancy. And for the baby who said that she had a, her baby was positive, how long should I wait to transfer my other embryos? Good question. We recommend waiting at least one year postpartum.
And certainly making sure that you’re done nursing if you’re nursing or lactating and that your cycles have resumed. Occasionally, we would defer to your OB-GYN, not occasionally, but usually we would refer to your OB-GYN’s advice. If you had a very complicated postpartum course or a cesarean that took a long time to heal, they might recommend even a little bit longer than a year. But about a year is probably a good time.
And we look forward to seeing you back in six months, or yeah, about 6 to 8 months. So we had the eight, this is another question, we had eight IUIs that didn’t work. What do you recommend for us now? We are 33 and 31.
Well, luckily, you’re still in a really good age range for meeting your fertility family building goals at 33 and 31. And I’m so sad to hear that you did 8 IUIs that haven’t yet worked. I think at that point, I would strongly recommend to move on to IVF if that’s within your within your ability to do so. IVF has a much higher success rate, and particularly after 8 unsuccessful IUIs, we would not want to continue doing further IUIs for you.
Another question is, My AMH is low. Could I still conceive with my own eggs? Yes, as long as you’re ovulating and releasing eggs. AMH is a measure of egg quantity. It’s a good marker for how many small follicles might be present, how many eggs we can get at one time in an IVF cycle, but it is not a marker of egg quantity.
quality. So particularly for younger women with a lower AMH, they have the same monthly chance of conceiving as any other woman their same age in a natural cycle. A low AMH doesn’t really predict the chance of conceiving on your own in a natural cycle.
Jaye Adams 32:48
Well, thank you everyone for tuning in. I appreciate your questions and your interest. And I really, really wish you all the best in your fertility journey. Come see us at Positive if we can help you with diagnostics and treatment. We’d love to get some of you going on your family building journey.
Oh, so somebody’s asking What is the, what is the BMI cut off? So for IVF, because there is pretty heavy analgesia and sedation for that surgical procedure, but you’re breathing on your own, your airway is unprotected in the meaning that you don’t have a breathing tube in, we have a BMI cut off of 40 for IVF for the office-based anesthesia.
I think for IUI, BMI over, we don’t really have a procedural cutoff, but when the BMI is over 45, would you recommend working on weight loss in parallel with treatment and having a consult to kind of go over the extra obstetrical and pregnancy risk related to being pregnant at a higher BMI?
Ligia Popescu 33:36
Right.
Ligia Popescu 34:02
I want to tell the audience that we have another webinar coming up August 3rd. This time, Dr. Anderson, who is our lab director at Positive, is going to be going behind the scenes, taking you into the IVF lab, sharing with you what’s happening back there to, you know, protect you and protect your embryos and eggs and sperm
Ligia Popescu 34:22. I’m going to put the registration link right here in the chat now.
Love to see you for that third webinar. And if you could advance to the next slide for a word from our sponsor.
So this webinar series is brought to you by Pozitivf Fertility. If you would like to schedule an appointment or give us a call, we would love to see you. We have an offer of $499 for a fertility workup. And we have just announced extended hours in our San Antonio and Houston offices.

Jaye Adams 35:16
Thank you. Wish you the very best. All right, take care. Thanks, everyone.
Audience Questions and Answers
1. Question: Is there generally a certain amount of times the IUI may have failed before you consider moving to IVF?
Answer: It differs by couple, but IUI cumulative success usually maxes out around three to four cycles. Many couples consider moving to IVF after two or three IUIs, depending on age, patience, and financial resources.
2. Question: My first IUI cycle ended in a miscarriage. I’m 40 years old. Is it reasonable to go straight to IVF?
Answer: Yes, IVF may be reasonable at age 40, especially if time and future family-building goals matter. Since IUI did result in pregnancy once, another IUI could work, but spending many months on repeated IUIs may not be ideal. IVF can also allow embryo banking for future pregnancies.
3. Question: We have 12 donor eggs from a 24-year-old and my husband has excellent sperm. How many embryos should we expect, and should I do PGT-A?
Answer: ASRM guidelines generally do not recommend PGT-A as cost-effective for donor egg cycles. With a 24-year-old donor, the euploid rate is expected to be high, possibly around 70% or higher. Testing remains a personal decision, but many embryos may already be chromosomally normal.
4. Question: My partner and I are dealing with male factor infertility and low sperm count. Is IUI even an option, or do we go straight to IVF?
Answer: It depends on the severity of the sperm count issue. IUI works best when there are at least about 10 million moving sperm after washing; 5 to 10 million may still be reasonable in some younger couples. With very low counts, especially under 5 million total motile sperm or under 1 million, IVF with ICSI is usually recommended.
5. Question: I’m anxious about injections. Can you talk about the difference in physical toll and medication protocols between an IUI and an IVF cycle?
Answer: IUI is usually low intensity, often involving oral medication for five days, one or two ultrasound checks, and sometimes one trigger shot. IVF is more physically demanding, typically requiring 8 to 12 days of injections, frequent monitoring, and a sedated egg retrieval.
6. Question: After a loss, when is a good time to try again?
Answer: For most first-trimester losses, patients are often released to try again after the pregnancy has passed and after the next normal menstrual cycle. Older guidance suggested waiting several months, but evidence does not show a higher loss rate if conception happens after the first cycle. Emotional readiness and the details of the loss should also guide timing.
7. Question: My partner and I were diagnosed with unexplained infertility. Everything looks normal on paper, but we’re just not getting pregnant. Where do we start on the fertility care ladder?
Answer: Unexplained infertility is common. A typical approach is to begin with about three cycles of medicated IUI. If those do not work, IVF may serve as both treatment and diagnosis because it allows the clinic to observe fertilization and embryo development directly.
8. Question: If IUI is cheaper but has a lower success rate, is it financially better to go straight to IVF, or try several IUIs first?
Answer: The best financial choice depends on diagnosis, age, and prognosis. Three IUI cycles may cost much less than IVF and may provide a worthwhile cumulative chance of success for some families. However, if factors such as damaged tubes, very low sperm count, severe endometriosis, or age make IUI success very low, saving funds for IVF may be smarter.
9. Question: I’m terrified of triplets or higher-order multiples. Does fertility treatment drastically increase the risk, and is that risk higher with IUI or IVF?
Answer: Higher-order multiple risk can be higher with IUI because more than one egg may ovulate and fertilization cannot be controlled. Modern IVF often uses single embryo transfer, which greatly reduces the risk of higher-order multiples. An embryo can split, but that is rare.
10. Question: We’ve been trying timed intercourse with ovulation strips at home for a year, and it’s hurting our intimacy and mental health. Will moving to a clinic make it feel even more clinical?
Answer: Moving to a clinic can actually relieve some of the relationship pressure. With IUI, the clinic takes over monitoring, timing, and sperm placement, allowing intimacy to feel less tied to conception logistics.
11. Question: I’m 51 years old and want to have a baby. What are my options?
Answer: Pregnancy with one’s own eggs at 51 is extraordinarily rare. Main options may include donor eggs, donor embryos, and in some situations a gestational carrier, depending on clinic policies, health considerations, and age limits.
12. Question: Before trying the first rung of the ladder, how can lifestyle changes like diet, quitting vaping, or supplements improve our chances of avoiding IVF?
Answer: Lifestyle changes can support egg and sperm quality. Quitting smoking and vaping, reducing alcohol, improving diet, exercising, sleeping well, and considering antioxidant support may help. Because sperm development takes about 90 days, lifestyle changes can be especially helpful for male factor concerns. Weight and metabolic improvements may also improve ovulation or semen analysis enough to make lower-tech options more successful.
13. Question: What are the chances of having twins with donor eggs?
Answer: With single embryo transfer, the chance of twins is similar regardless of whether embryos came from donor eggs or autologous eggs. Donor egg embryos are generally managed according to the donor’s age-related embryo transfer guidelines, which usually favor transferring one embryo at a time to reduce twin pregnancy risk.
14. Question: After having a baby, how long should I wait to transfer my other embryos?
Answer: The recommendation given was to wait at least one year postpartum, ensure nursing or lactation has ended if applicable, and confirm cycles have resumed. OB-GYN guidance may recommend longer after a complicated delivery or recovery.
15. Question: We had eight IUIs that didn’t work. What do you recommend now? We are 33 and 31.
Answer: At ages 33 and 31, there is still a favorable age range for fertility goals. After eight unsuccessful IUIs, IVF is strongly recommended if feasible, because continuing IUIs is unlikely to be productive.
16. Question: My AMH is low. Could I still conceive with my own eggs?
Answer: Yes, if ovulation is occurring. AMH reflects egg quantity, not egg quality. In younger women, low AMH does not necessarily predict the chance of natural conception in a given cycle.
17. Question: What is the BMI cutoff?
Answer: For IVF with office-based anesthesia, the stated BMI cutoff is 40 because of sedation and airway safety considerations. For IUI, there is not the same procedural cutoff, though BMI over 45 may prompt discussion of weight loss in parallel with treatment and counseling about pregnancy risks.

Hello, everyone, and welcome to IVF Lab Behind the Scenes, our third of our seven webinar series, fertility education and webinar series. And we’re happy to have you here today. Thank you for spending your time with us.
Our guest today is Brittany Garza. She’s an embryologist at Pozitivf Fertility.
And today she’s going to be giving us a very exciting presentation straight from the lab. So here is a quick look at our agenda.
Before we begin, though, I would like to just give you a few audience tips. We want to answer all of your questions, so please feel free to use the Q&A or put your question in the chat. We will get to as many questions as we can. We also encourage audience reactions. If you’d like something you hear or you want to give a shout out or thumbs up, please do. Also, a recording of this presentation will be sent out to everyone. And please ask your questions because here we have this time with this embryologist and I really want to make the best of it.
So last week, we talked about IVF versus other fertility treatment options. But today we’re going to go, like I said, step into the lab, and I’m going to turn it over to you, Brittney. But if you could just share a bit about yourself first, that would be great.
Brittney Garza 1:40
Hi everyone, my name is Brittney Garza and thank you so much for the opportunity to be here today. I’m really excited to connect with you and give you a behind the scenes look at what actually happens inside the embryology laboratory, especially here at Pozitivf. I’ve been with Pozitivf since 2023.
I’ve worked as a clinical embryologist since 2020.
But actually, my journey into embryology goes back to when I was a sophomore in high school. That’s when I decided to pursue this career. And I can honestly say that since then, my passion for this field has only grown. Because at the end of the day, this isn’t just science to us. This is people’s futures and their families and their biggest hopes.
So whether you are beginning your fertility journey, currently undergoing treatment, or just simply curious, I hope today gives you a better understanding of the level of care, precision, and teamwork that goes into each and every single step. Before we get started, I’ll briefly review my disclosures.
These are my current professional affiliations. I also want to note that any patient information or images, videos you’ll see today are my own. Personal medical information, which I’ve chosen to share for educational purposes. And with that, let’s get started.
So first, I want to take a step back into time to understand just how we got here. The dream of building a family has always existed, but July 25th, 1978, changed reproductive medicine forever. On that day, Leslie and John Brown welcomed their first IVF baby, Louise Joy.
Brown. Their success was only possible because they trusted three pioneers, which are pictured here at the top right. Those people are Patrick Steptoe, Bob Edwards, and Jean Purdy. And I always like to highlight Jean Purdy. She was one of the first embryologists whose work helped lay
the foundation for everything we do today.
But this was no overnight success. It actually took more than 100 treatment attempts before Luis was born. And just three years later, in 1981, Elizabeth Carr became the first IVF baby born in the United States after 48 attempts.
So let’s think about that for a second.
In 1978, IVF success rates were less than 1%. By 1981, they nearly doubled to 2%. Today, many fertility centers achieve pregnancy rates between 50 to as high as 60%. So what began as a bold experiment with almost impossible odds is now something that has helped millions of families worldwide.
More importantly, though, we are no longer asking, can this work? We are focused on doing better, safer, and more consistent IVF.
So the story did not end in 1978. It actually continues today. July 25th is now recognized as World Embryologist Day, a day we proudly celebrate as embryologists around the world. While IVF has evolved dramatically, one thing that has never changed
is it takes a dedicated team to help make the dream of building a family possible. Pictured here are our positive teams across Houston, San Antonio, and Austin. We are honored to continue the legacy of those early pioneers by partnering with our patients every step of the way.
How do we do this? Well, we ring it all together. At Pozitivf, our focus isn’t just on achieving success, it’s achieving it safely. At every clinic, patients ring a graduation bell when they complete their journey with us. When that bell rings, our entire team celebrates because we know
what it took to get there. The moment is built on collaboration, communication, and accountability. We start each day together believing that everyone has an idea and that every single role matters. Through clear communication, whether it’s verifying requisitions, confirming
patient’s identification or the documentation that it takes at every step, we follow what’s called our wingman contract, which reminds us to trust each other, speak up, and double check everything. Because we are just not individuals. We are a team of teams and patient safety.
is everyone’s responsibility. Success in IVF is not luck. It’s process, discipline, and teamwork done right.
Now, let’s step into the IVF app.
One of the first things we want to know is, how’s our swim team looking today? Here at Pozitivf, we give our swim team a thorough evaluation. We’ll look under the microscope. We use a Kasa system called the Lens Hook, which you can see here on the left side, which is basically like having a statistician for swimmers.
It helps us look at things like how many swimmers do we have? How well are they moving? Are they swimming in the right direction? What do they look like? That gives us important information about just sperm or specimen parameters in general. And the great thing is, is we can get those results
right back to our physicians and patients the same day.
So before our swim team ever gets a chance to meet the egg, we’ve already done a full scouting report to see exactly what we’re working with.
So once a patient is ready for IVF, the lab work actually starts before retrieval day. We call this day negative 1 or day minus 1. This is when we build multiple layers of protection around the patients and their specimens. Each patient gets a unique accession number, patient ID, along with detailed cycle paperwork,
confirming all the identifiers like name, date of birth, what color tape we’re using for quick visual identification. But on top of all of those layers, we’ve chosen to use RiWitness, which is our electronic witnessing system. Each patient has a unique tag that follows every single dish.
we place an RFID tag on, like specimen cups, insemination tubes, culture dishes, so everything is consistently tracked.
as simple checkpoints. So the right specimen always stays with the right patient. In IVF, we’re not just aiming for accuracy, but we are striving for perfection. And this is what those safety layers look like in our lab.
Day zero is retrieval day.
Our patients receive a wristband that includes their name, date of birth, and their partner’s information, and the plan for the cycle, whether that’s PGTA or classic IVF. The wristband is scanned electronically, linked to their swim team and to the dish their eggs and embryos will eventually grow in. So as we move
Ligia Popescu 9:15
Hey, Brittney, I’m going to, I just need you to pause real quick. Not everyone can see your presentation. Can you share it from your screen?
Brittney Garza 9:29
Sure.
Ligia Popescu 9:33
We can’t see all the fancy slides.
Just give us one second, folks.
Like I said, we are testing out a new format in the actual lab room.
Brittney Garza 9:52
Ice cream.
Ligia Popescu 9:53
Here you go.
Yeah.
There you are, oh, perfect.
Brittney Garza 10:20
So we were at our retrieval day, right?
Ligia Popescu 10:23
Yes, mhm.
Perfect.
Brittney Garza 10:35
All right.
Backing it up, day zero is our retrieval day. Our patient receives this wristband here. That includes their name, date of birth, and their partner’s information, as well as the plan for the cycle, whether it’s PGTA or classic IVF. In this case, it was IVF classic. That wristband is scanned electronically and linked to the swim team.
and the dishes that their eggs and embryos will be growing in. So as we move through each step, those identifiers continue to follow the patient and their specimens. During the retrieval, the physician is aspirating the fluid from each follicle. The follicular fluid comes directly to us in the lab.
where the embryologist begins to search for the eggs. And the really cool part is the patient’s family and friends can watch us find them in real time. Here is my personal video of when my family and friends watch my retrieval.
If you look on the video here, you can see two screens. One allows them to view the follicles that are being aspirated, while the other one is allowing them to see the eggs once we find it. On the right here, you can see that Ellie, one of our supervisors from Pozitivf San Antonio, is performing an egg retrieval and searching for those eggs.
And when I say searching, I mean searching.
We’re searching every tube, every drop, every follicle. We’re making sure that we find every egg that we possibly can. As each egg is found, we carefully move it into a holding medium where it stays protected and supported until the retrieval is complete.
In the lab, day zero really begins here, and where all of that preparation, communication, and accountability, and all of those layers of protection come to play.
So we are still on day zero. How do we know which ones are mature? Now that we found our eggs, it’s time to see. First, we have to clean them up. So right here is where we can see those eggs being
pipetted in and out of that pipettor. And we are doing this with an enzyme called hyaluronidase. And we’re also mechanically removing those excess granulosa and cumulus cells, which you can see happening here. Once they’re cleaned, we look for something that’s called a polar body.
like you see here. This right here is an example of a polar body and what would be what we call a mature egg. Now, a mature egg for us means that is ready for fertilization. Not every mature, not every egg that we retrieve will be mature. Typically about 60 to 80%
will be mature.
So now comes ICSI. It’s day zero. Now we know which eggs that are mature. It’s time to pick the MVP of our swim team. We are still on day zero, and this is when we perform ICSI, which stands for Intracytoplasmic Sperm Injection. At positive, we perform ICSI for every patient.
While at many clinics, this may be a recommended, this may be recommended after a failed conventional insemination cycle with additional costs, but we actually do this for all of our patients.
So, so here…
You can see the egg is being held.
and the polar body is right here at 6 o’clock. The egg is now being punctured, and we gently insert that needle and apply suction until that membrane actually breaks. You’ll see the sperm jump back right there. Once that happens, we gently move our pipette or our needle forward, releasing that lucky swimmer.
Ligia Popescu 14:30
And that little tiny dot is the swimmer. The little tiny dot, wow.
Brittney Garza 14:34
Correct.
Yeah, so there’s the swimmer going inside the egg. And on the right, that is just the microscope where embryologists perform our ICSI. After all that talk about a swim team, only one gets drafted for each mature egg.
Before we leave day zero, though, let’s see those layers of protection in action. This is one of our supervisors, Danielle, at our Pozitivf Houston location. She’s going to show us how the electronic witnessing system follows our specimens throughout the lab. What happens and what happens if there is ever a mismatch.
Ligia Popescu 15:24
I’m not sure we have the sound on this.
I don’t think we’re hearing it, but we’ll get the picture, I think, anyway.
Brittney Garza 15:43
So right here is when the culture dish is being introduced. That’s the correct sperm sample. Here we’re verifying that it’s the right patient with the right specimen.
Won’t prompt us unless we have the right patients.
Here you can see the exact workflow of those RFID tags being applied. We’re going to proceed forward and everything’s good to go for the insemination.
Now, let’s just say we accidentally have the wrong sperm. This is what happens next.
Prompted with items do not match, meaning we cannot proceed, and there is a huge alarm that goes off, so everyone will know.
Brittney Garza 16:28
And that is something we obviously never want to do. But it’s nice to see it live and in action, because I do know that that is a common question, right? We hear all of these stories on the news about patients having the wrong babies. This is a actual
live example of what would happen if that were to occur.
Ligia Popescu 16:52
It’s so fascinating that your actual equipment won’t let you do the procedure without that match.
Brittney Garza 16:59
Correct, yeah. We’re thankful for it. Now that we’ve made it through day zero, though, it’s time to let our embryos do their thing. From here, they’ll stay nice and cozy in our incubator, and we actually won’t pull their dish out again until day five. But let’s fast forward through what’s happening while we wait.
Starting at this top left, we are seeing that these two circles here, which we call pronuclei, we get one from mom and one from dad. A 2PN is what we traditionally look for as a sign of normal fertilization. Next to it, you can see here
There is a 1PN and a 3PN. Those are considered abnormally fertilized. In some labs, these actually may not even continue in culture. But research and literature has shown, has demonstrated to us that embryos with abnormal fertilization can still have reproductive potential.
And this is why we try not to disturb our embryos unnecessarily. Every time that dish comes out of the incubator, we’re exposing it to changes in temperature and pH. So sometimes the best thing an embryologist can do is simply leave them alone and let them grow. Moving across the bottom here,
You can see.
that we have a four cell, which is usually around day two.
Here is a day three embryo, which is around 8 cells. And here is what we called a compacting morula. Now, on day two and day three, these cells are actually called blastomeres. And when they start to come together, they like to compact. And this is what we call the morula, which actually got its name from mulberry.
And a fun fact, back in the earlier days of IVF, we actually used to transfer a lot of early staged embryos or cleavage stage embryos, which is one of the reasons why IVF used to be associated with much higher chance of multiples. Now,
Most clinics, including ourselves, do day flaps.
Over here is one of our incubators, their home away from home. And while all of that growth is happening.
This incubator is going to be monitored. You can see a little computer here, giving us the statistics on how that incubator is actually functioning. So we’ve made it through days one through 4 without disturbing them. Now it’s time to see what they’ve been up to on day five.
This is when we begin assessing for blastocyst development. If an embryo needs a little more time, we’ll continue their growth through day six and sometimes day seven. At the blastocyst stage, we can see two important cell types. The compact ball of cells, which I have highlighted in yellow here, is the inner cell mass. These are the cells that will actually become
the baby’s body and the surrounding trophectoderm cells will contribute to the placenta. Everything is surrounded in this shell. The shell actually is called the zona pellucida and it originates from the egg. On the right here, this is what’s called the gardener grading system.
This is how we grade our embryos based on their development of the inner cell mass and trophectogerm. But I want to remind you that embryo grading is not everything. It can be subjective and it varies between clinics. We’ve seen lower graded embryos become beautiful and healthy babies.
For patients that don’t opt to do PGT, which is pre-implantation genetic testing, this is also the stage where we began putting our embryos into a biological pause. Here at positive, we began freezing embryos at the blastocyst stage, which we represent here with the three.
As the embryo develops and gets much bigger, the grading number increases to reflect the growth and the expansion of the blastocyst.
And I want everyone here to remember that IVF is a funnel. We might start off with 12 eggs. Out of those 12, we might have 10 mature. Out of those 10 mature, maybe about 8 fertilized.
After those eight that fertilize, maybe we’ll have 4 blastocysts, and around 2 will be genetically normal. So when an embryo mates it all the way up into this point, a blastocyst, that’s a pretty big accomplishment for something that’s so tiny.
For patients that undergo PGT, our embryos have three more stops along the way. The first stop is going to be the cell sampling, where we take a few of the trophectoderm cells from the embryo. The next step is going to be the tubing, where those tiny cells are carefully placed into small PCR tubes.
and sent off for genetic testing. And finally, when the embryo enters A biological pause where we safely freeze and preserve the embryo until we await the results. Those results give us a look at the embryo’s chromosomes, helping us identify which embryos have the correct number. PGTA can
also tell us the genders for each embryo. And here at Pozitivf, patients can use that information for family balancing or gender selection when choosing which embryo to transfer.
Brittney Garza 22:54
So.
So now that we know what the workflow looks like for patients that opt to do PGT, let’s look at how we do it.
Over here on the left, you can see an example of cell sampling or an embryo biopsy. You see those tiny cells in the micropipette there? We’re carefully going to take them off.
And after we get those cells from the embryo, that is when they’re placed into this next tube here.
They’re washed and put in this tiny PCR tube. And when I say they’re tiny, I mean they are tiny. We’re working very carefully here. I mean, we’re even wearing gloves to prevent any type of contamination. Each tube is actually labeled with the patient’s initials as well as that embryo specific number. And when it goes into this kit here, this kit is actually an extra
layer of identification. It has the patient name on there as well as their unique accession number, which you can see right up here. Then off to the genetics lab it goes. We typically get those results back within 10 business days. And one thing I always like to point out about PGTA is it is a selection tool.
especially with patients that are greater than 35. Now, it doesn’t necessarily mean that it increases your pregnancy rate, but what it does help with is to prioritize which embryo to transfer first and ultimately will help time to pregnancy.
So now that our embryos are in a biological pause, how do we keep them and our eggs and our swim team safe? Remember all of those layers of protection that we talked about. They don’t stop once an embryo is frozen. They continue throughout storage too. On the left, you can see that the embryo is clearly labeled with
patient name, date of birth, the PGT number, if they have one, a freeze date, and how young the embryo is. Each embryo also has a unique barcode that’s linked back to the original dish it came from, the patient’s wristband, and even the swim team. Keeping every step of the process secure,
and connected. The embryo devices are then placed in a storage goblet, which holds multiple embryos. The color-coded tag at the top is assigned based on the patient’s last name, allowing our team to quickly and safely locate the correct embryos whenever they are needed. It’s just one layer of protection.
Because in our lab, precision isn’t optimal, it’s essential. The next time these embryos leave storage will be for one of the most exciting milestones in the IVF journey, the embryo transfer. At that time, the embryo’s barcode is once again matched to the patient’s wristband, adding another verification step.
to ensure the right embryo is transferred to the right patient. So over here is our tank where all of those beautiful embryos are stored and all of those colors represent a last name here. So we are able to identify those embryos as quick as we can.
And now it’s finally time for one of our embryos to come out of biological pause for transfer day. We begin by warming our solutions to make sure they’re at the perfect temperature. And then with multiple team members witnessing every step, we carefully retrieve one of those embryos from the storage and gently thaw it.
Once that embryo has reawakened, we take a photograph and meet with the patient to share the special moment. We show them their embryo. We explain how beautifully it looks and how it survived the thought. And then comes the moment everyone has been waiting for, which is the embryo transfer.
Just like every step before, the entire process is carefully documented and witnessed to ensure the highest level of safety and accuracy.
From egg retrieval to fertilization to blast development to the biopsy to the freezing and now the thawing, every step has led to this moment. And after the transfer, we send our patients home with this special keepsake. The little culture dish that once held their embryo, we like to call it the embryo’s first crib.
A small reminder of where their family’s journey began.
So we followed our eggs and embryos in swim tune their entire journey, but even when we’re not physically in the lab, our job doesn’t stop. Embryologists are actually on call 24-7, 365 days out of the year because keeping these specimens safe is truly an around-the-clock responsibility.
On the left here, you can see one of our systems we use to continuously monitor our equipment, with temperature readings being recorded almost every minute and alarms that alert us if something is wrong. On the right here, we can see, we can take a look at those readings and trends over time. This helps us recognize when something may start to change,
before it actually becomes a problem.
That allows us to be more proactive than reactive and continuously evaluates how our systems and equipments are performing. Because even when the lab is quiet, we are still watching.
And here’s another example of how we protect every specimen around the plot. This is our Boreas system, our liquid nitrogen tank monitoring system. It continuously monitors the weight of our tanks, helping us make sure they stay properly filled at all times. On this graph here, we can see how full a tank is, track the evaporation rate over time, and know exactly when we would
reach a low weight alarm. It allows us to identify trends between different tanks or locations before they become a problem. This right here is actually true advanced modern technology. These systems require a much greater investment than conventional
monitoring. But here at Pozitivf, we truly believe that when it comes to the quality and patient safety, we absolutely have to do the most. And that’s something we’re truly proud of. We offer state-of-the-art technology while continuing to make IVF as cost-effective and accessible as possible.
After all of that work, it’s finally time to wrap up our day in the lab. Before anyone heads home, we do one last walkthrough, we clean down our surfaces, make sure our equipment is turned off, and give every tank one last check to make sure everything looks exactly how it would. Then we take a look at what’s coming tomorrow, get ourselves organized and prepared to do it
all over again. Because in the IVF lab, today may be finished, but there’s always another egg-citing day waiting for us tomorrow.
And after all of that, this is the part that makes everything worth it. We followed our swim team, our eggs, all of our embryos, and the next time we get to see them, you can say they look a little different. Throughout the year, positive host events like pictures with Santa or baby reunions, and even the Walk of Hope,
These are moments when we get to meet our beautiful babies we once knew as just a few tiny cells under a microscope. I also want to take a moment to recognize our incredible lab teams at all of our locations and our lab director, Dr. Tony Anderson. Everything you saw today takes an entire team working together behind the scenes, and I’m incredibly grateful.
for the dedication and the care they bring to our patients every single day. It really brings everything full circle and reminds us just why we do what we do. T
Thank you all for coming behind the scenes with me today. I hope you gained just a little more insight into the IVF lab and just how much science, Teamwork, heart goes into helping build a family.
And here at Pozitivf, we believe a child having a child is having is a universal human right.
Anyone have a question here? What is the favorite part of your job? This part, getting to see those beautiful babies and smiles and even the cries. This is my favorite job. Favorite part of your job, though.
Ligia Popescu 31:52
I have a question here from the live audience. How do you choose which embryo to transfer first if you have multiple embryos?
Brittney Garza 32:03
That’s a great question. So we will look at embryo age. We prioritize our day five embryos over day six or day seven, simply because they were ready first.
And secondary to that, I would say if they’re not PGT, we would look at embryo grade.
But if they are PGT, we’d obviously go with which ones are you deployed first. And sometimes it’s a combination of all three of those parameters.
Ligia Popescu 32:31
And what does euploid mean?
Brittney Garza 32:34
Euploid is an average karyotype of the embryo that is the right number. So we get 23 from mom, 23 from dad. Anything more or less than that would be considered aneuploid.
Ligia Popescu 32:47
Gotcha. Another question here. What special steps are taken if we have very few eggs or swimmers?
Brittney Garza 32:58
There are no special steps. No matter your egg number, we treat all eggs the same. There is nothing, we do everything we can for each egg that we get in the lab. It doesn’t matter if you retrieve 50 or one, it’s treated the exact same way.
Ligia Popescu 33:14
Another question, are embryos damaged during the biopsy?
Brittney Garza 33:25
Embryos are not damaged. When embryos do not survive a biopsy, it’s likely due to the quality.
My thoughts on embryo glue is you can get patients pregnant with the correct media and with the correct technique and an awesome doctor. I don’t think it depends on one solution to get a patient pregnant.
Ligia Popescu 34:05
Another question here, how do you ensure that the egg actually, that the fertilization process actually happens after you drop off the swimmer?
Brittney Garza 34:18
Yep, so that is probably referring to a fertilization check. And that is something that we do not do here at Positive. What we consider to be fertilized are eggs that cleave or they divide. So anything greater than A1 cell will be an indication for us that fertilization did occur.
So we won’t see that until around day five.
Ligia Popescu 34:43
Another question here, why do some eggs or embryos arrest?
Brittney Garza 34:52
That’s a great question, so…
Some of the embryos are rest because in the beginning, from day zero to day three, that embryo is dependent on the maternal DNA. After day three, it actually is dependent on the embryo to kick that energy in and continue the growth.
Now, most embryos actually do a rest on day three because of that.
lack of activation that occurs. So that is honestly why most embryos rest. But ultimately, in order for me really to assess that question, I need to look at the embryology records and ultimately see why the embryo did not continue.
Ligia Popescu 35:35
I have a question. We talked about the incubators, the home away from home, and how exactly are embryos protected outside of the body?
What is happening in there?
Brittney Garza 35:51
Yeah, many things. So we have a special media. It has all the components to get to keep the embryo preserved and growing. And we have state-of-the-art oil. That oil, you know, protects those embryos at all costs, pulling anything that could be a contaminant to the embryo. It actually stops it at the surface before it even reaches the drop.
And on top of that, it’s keeping them in the incubator safe and sound with nobody grabbing their dish and putting them at risk for anything. It’s truly about keeping those embryos preserved and safe and away from light and trying to really mimic what they would be doing in the human body.
Brittney, I have a question. Is a 5BB embryo better than a 4AB?
If they were both euploid, meaning they had the correct chromosomal normality and there was not a gender preference, I would likely go with the 5 BB because it is at a later stage of development, meaning it was likely ready.
Both are euploid. One is the 5BB, one has a better score, but the five is representing that the embryo is further in development and survival of the fittest. That embryo was ready first. It is in my opinion that we should transfer it first.
Ligia Popescu 37:30
Another question. What is the survival rate of embryos during the thawing process?
Brittney Garza 37:30
Ohh. If we create the embryos and we thaw them 99.5%, maybe 99%.
If we get them from another clinic, and depending on what their vitrification steps, if there was a less young embryo where, you know, we weren’t doing vitrification, it could vary for sure.
Ligia Popescu 37:57
And then also, sorry, what is the, how long do you normally store embryos?
Brittney Garza 37:59
As long as the patient wants to date, there is no, you know, you can’t leave an embryo stored X amount of years.
We’re setting the record almost every year for the less young embryo to be transferred and create a live birth. There has not been to date an expiration as to how long you can keep your embryo stored.
or eggs or sperm. Swim team, sorry.
I got a question. I’m using donor sperm and eggs and euploid embryos. What are the chances that my body injects it because it’s not mine?
I would say that is very in detailed and depth question.
Me? Yes.
The question is, is what is…
It’s not any higher than if it was yours.
So the question is, is I’m using donor sperm and…
eggs and embryos, what is the likelihood that my embryos won’t stick around because they are not mine? And my answer to that question is it’s not any less likely than if they were yours, if the endometrium looks great, if the embryo is truly euploid.
And if all of the other parameters are treated equivalently, then it should not hinder anything. It might actually be better determining or depending on how young the patient is.
Ligia Popescu 40:00
I have a question here about vitrification. How do you prevent ice crystals?
From for me.
Brittney Garza 40:10
So how we prevent ice crystals from forming or recrystallization is when that embryo goes under the biological pause or the freezing state, these solutions are designed to pull out any water that is taking up the blastocele. Okay, so once that fluid comes out of the embryo throughout the vitrification process, there should be no water in the embryo to go ahead and create crystals if you are following your protocol correctly.
Ligia Popescu 40:44
Crystallize.
Ligia Popescu 40:51
Does A genetically normal embryo guarantee a live birth?
Brittney Garza 40:57
No.
know that there is no test or assessment that we can do to guarantee a live birth. If there was, we would absolutely do it, but the PGT is simply a tool to allow us to transfer the most competent embryos to help us achieve a live
It helps with time to pregnancy.
Fall embryo, stop progressing at day three, absolutely.
Ligia Popescu 41:35
Can you repeat the question?

So…
The question was, is if all of my embryos are rested around day three, is it worth it to keep trying? And my answer is absolutely.
I think what sets Pozitivf apart is IVF in general is a gamble. There is no guarantees. But what Pozitivf does is allow you more rolls at the dice. It’s a numbers game. So by keeping the cost lower, we can provide more rolls at the dice for our patients who truly need them.
And if you are someone out there where your embryos have arrested on day three and you are losing hope, this is your sign to lock back in and give us one more chance or give us one more chance because that is just maybe one batch and one batch closer to getting you to your dreams.
Ligia Popescu 42:34
And with that, I’m going to go ahead and share the next upcoming webinar that we have is exactly around that topic. Brittney, how do you go about even paying for your journey? You know, there’s lots of elements involved. There’s lots of questions involved. There’s anxiety around
the topic, but we’re just going to break it apart and we’re going to cover everything. I’m going to put the information in the chat as soon as I get done with this next slide, which is, thank you so much to Pozitivf Fertility, where Brittney is sitting right now and where I’m sitting right now.
We have multiple locations. We are offering a $499 fertility workup and new evening hours in San Antonio and in our Houston offices. So please give us a call. We would love to talk to you. Please reach out. And thank you so much to everyone for joining us.
And we hope you join us for our next one. Thank you.
Bye, everyone.

Hello, everyone, and welcome to IVF Lab Behind the Scenes, our third of our seven webinar series, fertility education and webinar series. And we’re happy to have you here today. Thank you for spending your time with us.
Our guest today is Brittany Garza. She’s an embryologist at Pozitivf Fertility.
And today she’s going to be giving us a very exciting presentation straight from the lab. So here is a quick look at our agenda.
Before we begin, though, I would like to just give you a few audience tips. We want to answer all of your questions, so please feel free to use the Q&A or put your question in the chat. We will get to as many questions as we can. We also encourage audience reactions. If you’d like something you hear or you want to give a shout out or thumbs up, please do. Also, a recording of this presentation will be sent out to everyone. And please ask your questions because here we have this time with this embryologist and I really want to make the best of it.
So last week, we talked about IVF versus other fertility treatment options. But today we’re going to go, like I said, step into the lab, and I’m going to turn it over to you, Brittney. But if you could just share a bit about yourself first, that would be great.
Brittney Garza 1:40
Hi everyone, my name is Brittney Garza and thank you so much for the opportunity to be here today. I’m really excited to connect with you and give you a behind the scenes look at what actually happens inside the embryology laboratory, especially here at Pozitivf. I’ve been with Pozitivf since 2023.
I’ve worked as a clinical embryologist since 2020.
But actually, my journey into embryology goes back to when I was a sophomore in high school. That’s when I decided to pursue this career. And I can honestly say that since then, my passion for this field has only grown. Because at the end of the day, this isn’t just science to us. This is people’s futures and their families and their biggest hopes.
So whether you are beginning your fertility journey, currently undergoing treatment, or just simply curious, I hope today gives you a better understanding of the level of care, precision, and teamwork that goes into each and every single step. Before we get started, I’ll briefly review my disclosures.
These are my current professional affiliations. I also want to note that any patient information or images, videos you’ll see today are my own. Personal medical information, which I’ve chosen to share for educational purposes. And with that, let’s get started.
So first, I want to take a step back into time to understand just how we got here. The dream of building a family has always existed, but July 25th, 1978, changed reproductive medicine forever. On that day, Leslie and John Brown welcomed their first IVF baby, Louise Joy.
Brown. Their success was only possible because they trusted three pioneers, which are pictured here at the top right. Those people are Patrick Steptoe, Bob Edwards, and Jean Purdy. And I always like to highlight Jean Purdy. She was one of the first embryologists whose work helped lay
the foundation for everything we do today.
But this was no overnight success. It actually took more than 100 treatment attempts before Luis was born. And just three years later, in 1981, Elizabeth Carr became the first IVF baby born in the United States after 48 attempts.
So let’s think about that for a second.
In 1978, IVF success rates were less than 1%. By 1981, they nearly doubled to 2%. Today, many fertility centers achieve pregnancy rates between 50 to as high as 60%. So what began as a bold experiment with almost impossible odds is now something that has helped millions of families worldwide.
More importantly, though, we are no longer asking, can this work? We are focused on doing better, safer, and more consistent IVF.
So the story did not end in 1978. It actually continues today. July 25th is now recognized as World Embryologist Day, a day we proudly celebrate as embryologists around the world. While IVF has evolved dramatically, one thing that has never changed
is it takes a dedicated team to help make the dream of building a family possible. Pictured here are our positive teams across Houston, San Antonio, and Austin. We are honored to continue the legacy of those early pioneers by partnering with our patients every step of the way.
How do we do this? Well, we ring it all together. At Pozitivf, our focus isn’t just on achieving success, it’s achieving it safely. At every clinic, patients ring a graduation bell when they complete their journey with us. When that bell rings, our entire team celebrates because we know
what it took to get there. The moment is built on collaboration, communication, and accountability. We start each day together believing that everyone has an idea and that every single role matters. Through clear communication, whether it’s verifying requisitions, confirming
patient’s identification or the documentation that it takes at every step, we follow what’s called our wingman contract, which reminds us to trust each other, speak up, and double check everything. Because we are just not individuals. We are a team of teams and patient safety.
is everyone’s responsibility. Success in IVF is not luck. It’s process, discipline, and teamwork done right.
Now, let’s step into the IVF app.
One of the first things we want to know is, how’s our swim team looking today? Here at Pozitivf, we give our swim team a thorough evaluation. We’ll look under the microscope. We use a Kasa system called the Lens Hook, which you can see here on the left side, which is basically like having a statistician for swimmers.
It helps us look at things like how many swimmers do we have? How well are they moving? Are they swimming in the right direction? What do they look like? That gives us important information about just sperm or specimen parameters in general. And the great thing is, is we can get those results
right back to our physicians and patients the same day.
So before our swim team ever gets a chance to meet the egg, we’ve already done a full scouting report to see exactly what we’re working with.
So once a patient is ready for IVF, the lab work actually starts before retrieval day. We call this day negative 1 or day minus 1. This is when we build multiple layers of protection around the patients and their specimens. Each patient gets a unique accession number, patient ID, along with detailed cycle paperwork,
confirming all the identifiers like name, date of birth, what color tape we’re using for quick visual identification. But on top of all of those layers, we’ve chosen to use RiWitness, which is our electronic witnessing system. Each patient has a unique tag that follows every single dish.
we place an RFID tag on, like specimen cups, insemination tubes, culture dishes, so everything is consistently tracked.
as simple checkpoints. So the right specimen always stays with the right patient. In IVF, we’re not just aiming for accuracy, but we are striving for perfection. And this is what those safety layers look like in our lab.
Day zero is retrieval day.
Our patients receive a wristband that includes their name, date of birth, and their partner’s information, and the plan for the cycle, whether that’s PGTA or classic IVF. The wristband is scanned electronically, linked to their swim team and to the dish their eggs and embryos will eventually grow in. So as we move
Ligia Popescu 9:15
Hey, Brittney, I’m going to, I just need you to pause real quick. Not everyone can see your presentation. Can you share it from your screen?
Brittney Garza 9:29
Sure.
Ligia Popescu 9:33
We can’t see all the fancy slides.
Just give us one second, folks.
Like I said, we are testing out a new format in the actual lab room.
Brittney Garza 9:52
Ice cream.
Ligia Popescu 9:53
Here you go.
Yeah.
There you are, oh, perfect.
Brittney Garza 10:20
So we were at our retrieval day, right?
Ligia Popescu 10:23
Yes, mhm.
Perfect.
Brittney Garza 10:35
All right.
Backing it up, day zero is our retrieval day. Our patient receives this wristband here. That includes their name, date of birth, and their partner’s information, as well as the plan for the cycle, whether it’s PGTA or classic IVF. In this case, it was IVF classic. That wristband is scanned electronically and linked to the swim team.
and the dishes that their eggs and embryos will be growing in. So as we move through each step, those identifiers continue to follow the patient and their specimens. During the retrieval, the physician is aspirating the fluid from each follicle. The follicular fluid comes directly to us in the lab.
where the embryologist begins to search for the eggs. And the really cool part is the patient’s family and friends can watch us find them in real time. Here is my personal video of when my family and friends watch my retrieval.
If you look on the video here, you can see two screens. One allows them to view the follicles that are being aspirated, while the other one is allowing them to see the eggs once we find it. On the right here, you can see that Ellie, one of our supervisors from Pozitivf San Antonio, is performing an egg retrieval and searching for those eggs.
And when I say searching, I mean searching.
We’re searching every tube, every drop, every follicle. We’re making sure that we find every egg that we possibly can. As each egg is found, we carefully move it into a holding medium where it stays protected and supported until the retrieval is complete.
In the lab, day zero really begins here, and where all of that preparation, communication, and accountability, and all of those layers of protection come to play.
So we are still on day zero. How do we know which ones are mature? Now that we found our eggs, it’s time to see. First, we have to clean them up. So right here is where we can see those eggs being
pipetted in and out of that pipettor. And we are doing this with an enzyme called hyaluronidase. And we’re also mechanically removing those excess granulosa and cumulus cells, which you can see happening here. Once they’re cleaned, we look for something that’s called a polar body.
like you see here. This right here is an example of a polar body and what would be what we call a mature egg. Now, a mature egg for us means that is ready for fertilization. Not every mature, not every egg that we retrieve will be mature. Typically about 60 to 80%
will be mature.
So now comes ICSI. It’s day zero. Now we know which eggs that are mature. It’s time to pick the MVP of our swim team. We are still on day zero, and this is when we perform ICSI, which stands for Intracytoplasmic Sperm Injection. At positive, we perform ICSI for every patient.
While at many clinics, this may be a recommended, this may be recommended after a failed conventional insemination cycle with additional costs, but we actually do this for all of our patients.
So, so here…
You can see the egg is being held.
and the polar body is right here at 6 o’clock. The egg is now being punctured, and we gently insert that needle and apply suction until that membrane actually breaks. You’ll see the sperm jump back right there. Once that happens, we gently move our pipette or our needle forward, releasing that lucky swimmer.
Ligia Popescu 14:30
And that little tiny dot is the swimmer. The little tiny dot, wow.
Brittney Garza 14:34
Correct.
Yeah, so there’s the swimmer going inside the egg. And on the right, that is just the microscope where embryologists perform our ICSI. After all that talk about a swim team, only one gets drafted for each mature egg.
Before we leave day zero, though, let’s see those layers of protection in action. This is one of our supervisors, Danielle, at our Pozitivf Houston location. She’s going to show us how the electronic witnessing system follows our specimens throughout the lab. What happens and what happens if there is ever a mismatch.
Ligia Popescu 15:24
I’m not sure we have the sound on this.
I don’t think we’re hearing it, but we’ll get the picture, I think, anyway.
Brittney Garza 15:43
So right here is when the culture dish is being introduced. That’s the correct sperm sample. Here we’re verifying that it’s the right patient with the right specimen.
Won’t prompt us unless we have the right patients.
Here you can see the exact workflow of those RFID tags being applied. We’re going to proceed forward and everything’s good to go for the insemination.
Now, let’s just say we accidentally have the wrong sperm. This is what happens next.
Prompted with items do not match, meaning we cannot proceed, and there is a huge alarm that goes off, so everyone will know.
Brittney Garza 16:28
And that is something we obviously never want to do. But it’s nice to see it live and in action, because I do know that that is a common question, right? We hear all of these stories on the news about patients having the wrong babies. This is a actual
live example of what would happen if that were to occur.
Ligia Popescu 16:52
It’s so fascinating that your actual equipment won’t let you do the procedure without that match.
Brittney Garza 16:59
Correct, yeah. We’re thankful for it. Now that we’ve made it through day zero, though, it’s time to let our embryos do their thing. From here, they’ll stay nice and cozy in our incubator, and we actually won’t pull their dish out again until day five. But let’s fast forward through what’s happening while we wait.
Starting at this top left, we are seeing that these two circles here, which we call pronuclei, we get one from mom and one from dad. A 2PN is what we traditionally look for as a sign of normal fertilization. Next to it, you can see here
There is a 1PN and a 3PN. Those are considered abnormally fertilized. In some labs, these actually may not even continue in culture. But research and literature has shown, has demonstrated to us that embryos with abnormal fertilization can still have reproductive potential.
And this is why we try not to disturb our embryos unnecessarily. Every time that dish comes out of the incubator, we’re exposing it to changes in temperature and pH. So sometimes the best thing an embryologist can do is simply leave them alone and let them grow. Moving across the bottom here,
You can see.
that we have a four cell, which is usually around day two.
Here is a day three embryo, which is around 8 cells. And here is what we called a compacting morula. Now, on day two and day three, these cells are actually called blastomeres. And when they start to come together, they like to compact. And this is what we call the morula, which actually got its name from mulberry.
And a fun fact, back in the earlier days of IVF, we actually used to transfer a lot of early staged embryos or cleavage stage embryos, which is one of the reasons why IVF used to be associated with much higher chance of multiples. Now,
Most clinics, including ourselves, do day flaps.
Over here is one of our incubators, their home away from home. And while all of that growth is happening.
This incubator is going to be monitored. You can see a little computer here, giving us the statistics on how that incubator is actually functioning. So we’ve made it through days one through 4 without disturbing them. Now it’s time to see what they’ve been up to on day five.
This is when we begin assessing for blastocyst development. If an embryo needs a little more time, we’ll continue their growth through day six and sometimes day seven. At the blastocyst stage, we can see two important cell types. The compact ball of cells, which I have highlighted in yellow here, is the inner cell mass. These are the cells that will actually become
the baby’s body and the surrounding trophectoderm cells will contribute to the placenta. Everything is surrounded in this shell. The shell actually is called the zona pellucida and it originates from the egg. On the right here, this is what’s called the gardener grading system.
This is how we grade our embryos based on their development of the inner cell mass and trophectogerm. But I want to remind you that embryo grading is not everything. It can be subjective and it varies between clinics. We’ve seen lower graded embryos become beautiful and healthy babies.
For patients that don’t opt to do PGT, which is pre-implantation genetic testing, this is also the stage where we began putting our embryos into a biological pause. Here at positive, we began freezing embryos at the blastocyst stage, which we represent here with the three.
As the embryo develops and gets much bigger, the grading number increases to reflect the growth and the expansion of the blastocyst.
And I want everyone here to remember that IVF is a funnel. We might start off with 12 eggs. Out of those 12, we might have 10 mature. Out of those 10 mature, maybe about 8 fertilized.
After those eight that fertilize, maybe we’ll have 4 blastocysts, and around 2 will be genetically normal. So when an embryo mates it all the way up into this point, a blastocyst, that’s a pretty big accomplishment for something that’s so tiny.
For patients that undergo PGT, our embryos have three more stops along the way. The first stop is going to be the cell sampling, where we take a few of the trophectoderm cells from the embryo. The next step is going to be the tubing, where those tiny cells are carefully placed into small PCR tubes.
and sent off for genetic testing. And finally, when the embryo enters A biological pause where we safely freeze and preserve the embryo until we await the results. Those results give us a look at the embryo’s chromosomes, helping us identify which embryos have the correct number. PGTA can
also tell us the genders for each embryo. And here at Pozitivf, patients can use that information for family balancing or gender selection when choosing which embryo to transfer.
Brittney Garza 22:54
So.
So now that we know what the workflow looks like for patients that opt to do PGT, let’s look at how we do it.
Over here on the left, you can see an example of cell sampling or an embryo biopsy. You see those tiny cells in the micropipette there? We’re carefully going to take them off.
And after we get those cells from the embryo, that is when they’re placed into this next tube here.
They’re washed and put in this tiny PCR tube. And when I say they’re tiny, I mean they are tiny. We’re working very carefully here. I mean, we’re even wearing gloves to prevent any type of contamination. Each tube is actually labeled with the patient’s initials as well as that embryo specific number. And when it goes into this kit here, this kit is actually an extra
layer of identification. It has the patient name on there as well as their unique accession number, which you can see right up here. Then off to the genetics lab it goes. We typically get those results back within 10 business days. And one thing I always like to point out about PGTA is it is a selection tool.
especially with patients that are greater than 35. Now, it doesn’t necessarily mean that it increases your pregnancy rate, but what it does help with is to prioritize which embryo to transfer first and ultimately will help time to pregnancy.
So now that our embryos are in a biological pause, how do we keep them and our eggs and our swim team safe? Remember all of those layers of protection that we talked about. They don’t stop once an embryo is frozen. They continue throughout storage too. On the left, you can see that the embryo is clearly labeled with
patient name, date of birth, the PGT number, if they have one, a freeze date, and how young the embryo is. Each embryo also has a unique barcode that’s linked back to the original dish it came from, the patient’s wristband, and even the swim team. Keeping every step of the process secure,
and connected. The embryo devices are then placed in a storage goblet, which holds multiple embryos. The color-coded tag at the top is assigned based on the patient’s last name, allowing our team to quickly and safely locate the correct embryos whenever they are needed. It’s just one layer of protection.
Because in our lab, precision isn’t optimal, it’s essential. The next time these embryos leave storage will be for one of the most exciting milestones in the IVF journey, the embryo transfer. At that time, the embryo’s barcode is once again matched to the patient’s wristband, adding another verification step.
to ensure the right embryo is transferred to the right patient. So over here is our tank where all of those beautiful embryos are stored and all of those colors represent a last name here. So we are able to identify those embryos as quick as we can.
And now it’s finally time for one of our embryos to come out of biological pause for transfer day. We begin by warming our solutions to make sure they’re at the perfect temperature. And then with multiple team members witnessing every step, we carefully retrieve one of those embryos from the storage and gently thaw it.
Once that embryo has reawakened, we take a photograph and meet with the patient to share the special moment. We show them their embryo. We explain how beautifully it looks and how it survived the thought. And then comes the moment everyone has been waiting for, which is the embryo transfer.
Just like every step before, the entire process is carefully documented and witnessed to ensure the highest level of safety and accuracy.
From egg retrieval to fertilization to blast development to the biopsy to the freezing and now the thawing, every step has led to this moment. And after the transfer, we send our patients home with this special keepsake. The little culture dish that once held their embryo, we like to call it the embryo’s first crib.
A small reminder of where their family’s journey began.
So we followed our eggs and embryos in swim tune their entire journey, but even when we’re not physically in the lab, our job doesn’t stop. Embryologists are actually on call 24-7, 365 days out of the year because keeping these specimens safe is truly an around-the-clock responsibility.
On the left here, you can see one of our systems we use to continuously monitor our equipment, with temperature readings being recorded almost every minute and alarms that alert us if something is wrong. On the right here, we can see, we can take a look at those readings and trends over time. This helps us recognize when something may start to change,
before it actually becomes a problem.
That allows us to be more proactive than reactive and continuously evaluates how our systems and equipments are performing. Because even when the lab is quiet, we are still watching.
And here’s another example of how we protect every specimen around the plot. This is our Boreas system, our liquid nitrogen tank monitoring system. It continuously monitors the weight of our tanks, helping us make sure they stay properly filled at all times. On this graph here, we can see how full a tank is, track the evaporation rate over time, and know exactly when we would
reach a low weight alarm. It allows us to identify trends between different tanks or locations before they become a problem. This right here is actually true advanced modern technology. These systems require a much greater investment than conventional
monitoring. But here at Pozitivf, we truly believe that when it comes to the quality and patient safety, we absolutely have to do the most. And that’s something we’re truly proud of. We offer state-of-the-art technology while continuing to make IVF as cost-effective and accessible as possible.
After all of that work, it’s finally time to wrap up our day in the lab. Before anyone heads home, we do one last walkthrough, we clean down our surfaces, make sure our equipment is turned off, and give every tank one last check to make sure everything looks exactly how it would. Then we take a look at what’s coming tomorrow, get ourselves organized and prepared to do it
all over again. Because in the IVF lab, today may be finished, but there’s always another egg-citing day waiting for us tomorrow.
And after all of that, this is the part that makes everything worth it. We followed our swim team, our eggs, all of our embryos, and the next time we get to see them, you can say they look a little different. Throughout the year, positive host events like pictures with Santa or baby reunions, and even the Walk of Hope,
These are moments when we get to meet our beautiful babies we once knew as just a few tiny cells under a microscope. I also want to take a moment to recognize our incredible lab teams at all of our locations and our lab director, Dr. Tony Anderson. Everything you saw today takes an entire team working together behind the scenes, and I’m incredibly grateful.
for the dedication and the care they bring to our patients every single day. It really brings everything full circle and reminds us just why we do what we do. T
Thank you all for coming behind the scenes with me today. I hope you gained just a little more insight into the IVF lab and just how much science, Teamwork, heart goes into helping build a family.
And here at Pozitivf, we believe a child having a child is having is a universal human right.
Anyone have a question here? What is the favorite part of your job? This part, getting to see those beautiful babies and smiles and even the cries. This is my favorite job. Favorite part of your job, though.
Ligia Popescu 31:52
I have a question here from the live audience. How do you choose which embryo to transfer first if you have multiple embryos?
Brittney Garza 32:03
That’s a great question. So we will look at embryo age. We prioritize our day five embryos over day six or day seven, simply because they were ready first.
And secondary to that, I would say if they’re not PGT, we would look at embryo grade.
But if they are PGT, we’d obviously go with which ones are you deployed first. And sometimes it’s a combination of all three of those parameters.
Ligia Popescu 32:31
And what does euploid mean?
Brittney Garza 32:34
Euploid is an average karyotype of the embryo that is the right number. So we get 23 from mom, 23 from dad. Anything more or less than that would be considered aneuploid.
Ligia Popescu 32:47
Gotcha. Another question here. What special steps are taken if we have very few eggs or swimmers?
Brittney Garza 32:58
There are no special steps. No matter your egg number, we treat all eggs the same. There is nothing, we do everything we can for each egg that we get in the lab. It doesn’t matter if you retrieve 50 or one, it’s treated the exact same way.
Ligia Popescu 33:14
Another question, are embryos damaged during the biopsy?
Brittney Garza 33:25
Embryos are not damaged. When embryos do not survive a biopsy, it’s likely due to the quality.
My thoughts on embryo glue is you can get patients pregnant with the correct media and with the correct technique and an awesome doctor. I don’t think it depends on one solution to get a patient pregnant.
Ligia Popescu 34:05
Another question here, how do you ensure that the egg actually, that the fertilization process actually happens after you drop off the swimmer?
Brittney Garza 34:18
Yep, so that is probably referring to a fertilization check. And that is something that we do not do here at Positive. What we consider to be fertilized are eggs that cleave or they divide. So anything greater than A1 cell will be an indication for us that fertilization did occur.
So we won’t see that until around day five.
Ligia Popescu 34:43
Another question here, why do some eggs or embryos arrest?
Brittney Garza 34:52
That’s a great question, so…
Some of the embryos are rest because in the beginning, from day zero to day three, that embryo is dependent on the maternal DNA. After day three, it actually is dependent on the embryo to kick that energy in and continue the growth.
Now, most embryos actually do a rest on day three because of that.
lack of activation that occurs. So that is honestly why most embryos rest. But ultimately, in order for me really to assess that question, I need to look at the embryology records and ultimately see why the embryo did not continue.
Ligia Popescu 35:35
I have a question. We talked about the incubators, the home away from home, and how exactly are embryos protected outside of the body?
What is happening in there?
Brittney Garza 35:51
Yeah, many things. So we have a special media. It has all the components to get to keep the embryo preserved and growing. And we have state-of-the-art oil. That oil, you know, protects those embryos at all costs, pulling anything that could be a contaminant to the embryo. It actually stops it at the surface before it even reaches the drop.
And on top of that, it’s keeping them in the incubator safe and sound with nobody grabbing their dish and putting them at risk for anything. It’s truly about keeping those embryos preserved and safe and away from light and trying to really mimic what they would be doing in the human body.
Brittney, I have a question. Is a 5BB embryo better than a 4AB?
If they were both euploid, meaning they had the correct chromosomal normality and there was not a gender preference, I would likely go with the 5 BB because it is at a later stage of development, meaning it was likely ready.
Both are euploid. One is the 5BB, one has a better score, but the five is representing that the embryo is further in development and survival of the fittest. That embryo was ready first. It is in my opinion that we should transfer it first.
Ligia Popescu 37:30
Another question. What is the survival rate of embryos during the thawing process?
Brittney Garza 37:30
Ohh. If we create the embryos and we thaw them 99.5%, maybe 99%.
If we get them from another clinic, and depending on what their vitrification steps, if there was a less young embryo where, you know, we weren’t doing vitrification, it could vary for sure.
Ligia Popescu 37:57
And then also, sorry, what is the, how long do you normally store embryos?
Brittney Garza 37:59
As long as the patient wants to date, there is no, you know, you can’t leave an embryo stored X amount of years.
We’re setting the record almost every year for the less young embryo to be transferred and create a live birth. There has not been to date an expiration as to how long you can keep your embryo stored.
or eggs or sperm. Swim team, sorry.
I got a question. I’m using donor sperm and eggs and euploid embryos. What are the chances that my body injects it because it’s not mine?
I would say that is very in detailed and depth question.
Me? Yes.
The question is, is what is…
It’s not any higher than if it was yours.
So the question is, is I’m using donor sperm and…
eggs and embryos, what is the likelihood that my embryos won’t stick around because they are not mine? And my answer to that question is it’s not any less likely than if they were yours, if the endometrium looks great, if the embryo is truly euploid.
And if all of the other parameters are treated equivalently, then it should not hinder anything. It might actually be better determining or depending on how young the patient is.
Ligia Popescu 40:00
I have a question here about vitrification. How do you prevent ice crystals?
From for me.
Brittney Garza 40:10
So how we prevent ice crystals from forming or recrystallization is when that embryo goes under the biological pause or the freezing state, these solutions are designed to pull out any water that is taking up the blastocele. Okay, so once that fluid comes out of the embryo throughout the vitrification process, there should be no water in the embryo to go ahead and create crystals if you are following your protocol correctly.
Ligia Popescu 40:44
Crystallize.
Ligia Popescu 40:51
Does A genetically normal embryo guarantee a live birth?
Brittney Garza 40:57
No.
know that there is no test or assessment that we can do to guarantee a live birth. If there was, we would absolutely do it, but the PGT is simply a tool to allow us to transfer the most competent embryos to help us achieve a live
