IVF Success Rates in Texas — What to Expect at Pozitivf

Q: Why do success rates vary so much between clinics?

Patient mix is the biggest variable. Clinics treating young, good-prognosis patients have higher rates than those treating older or more complex cases. Embryo transfer policy and PGT-A use also affect reported rates.

Q: What is a good success rate for IVF?

For a 35-year-old with favorable diagnosis, a live birth rate per transfer of 40% or higher is in line with leading clinics. For patients 38+, 25%+ per transfer with own eggs is reasonable.

When you’re considering IVF, the single most important number isn’t the price — it’s the probability that this cycle will result in a healthy baby. That number depends heavily on your age, your diagnosis, and the clinic you choose.

This page lays out the honest data: national IVF success rates by age, the methodology behind those numbers, and how Pozitivf’s outcomes compare.

National IVF Success Rates by Age (CDC + SART, 2022 data)

These are the most recent national benchmarks reported by the CDC’s Assisted Reproductive Technology National Summary and the Society for Assisted Reproductive Technology (SART). The data reflects autologous (own-egg) IVF cycles using fresh or frozen embryos.

Age Group	Live Birth Rate per Egg Retrieval	Live Birth Rate per Embryo Transfer
Under 35	50.0%	47.0%
35–37	38.1%	39.2%
38–40	24.8%	31.5%
41–42	12.4%	21.7%
Over 42	3.7%	13.1%

How to Read These Numbers

These are per-cycle rates. Cumulative rates across multiple cycles are higher:
– A patient under 35 with two IVF cycles has approximately a 70–75% chance of a live birth.
– A patient under 35 with three IVF cycles has approximately an 80% cumulative chance.
– For patients 38–40, three cycles cumulative rate is approximately 50–55%.

These rates assume good-prognosis diagnoses (no severe male factor, normal uterine anatomy, adequate ovarian reserve for age). Specific diagnoses change the numbers significantly:
– Diminished ovarian reserve (DOR): Rates drop 20–30%
– Severe male factor with ICSI: Comparable to age-matched controls
– Endometriosis stage III–IV: Rates drop 10–20%
– Repeated implantation failure: Rates drop significantly without intervention

What Drives Success Rates — Beyond Age

Age is the single biggest factor, but four other factors matter substantially:

1. Egg quality and quantity. AMH (Anti-Müllerian Hormone) levels predict how many eggs your ovaries will produce in stimulation. Lower AMH = fewer eggs retrieved = fewer embryos available for transfer = lower per-cycle rates. AMH testing is part of every Pozitivf workup ($75 standalone, included in the Baseline Fertility Evaluation).

2. Sperm quality. Concentration, motility, and morphology all matter. Severe male factor cases are addressed with intracytoplasmic sperm injection (ICSI), which directly injects sperm into eggs. ICSI rates are comparable to standard IVF for age-matched controls.

3. Uterine receptivity. A healthy endometrial lining, normal uterine anatomy (no fibroids, polyps, or scarring), and proper hormonal preparation all affect implantation. Saline ultrasound or HyFoSy ($395) is part of pre-treatment screening.

4. Embryo quality and genetic status. Embryos that have been genetically tested (PGT-A — preimplantation genetic testing for aneuploidy) and confirmed chromosomally normal implant at significantly higher rates than untested embryos in patients 35 and older. PGT-A adds $5,500–$6,500 to the cycle cost but typically improves per-transfer success rates by 15–25% in older patients.

How Pozitivf Optimizes for Success

Personalized stimulation protocols. Not every patient responds the same way to standard medications. Dr. Arredondo customizes ovarian stimulation based on AMH, prior response (if known), age, and underlying diagnosis.

Embryology lab quality. Pozitivf uses advanced incubation (time-lapse where applicable) and vitrification (flash-freezing) for embryos. Lab quality directly affects embryo development and survival of frozen embryos at thaw.

Single-embryo transfer (SET) as the default. Transferring one embryo at a time minimizes twin/triplet pregnancies, which carry significantly higher health risks. Cumulative success across multiple SET cycles is similar to (or better than) dual transfers, with lower complications.

Frozen Embryo Transfer (FET) for many patients. FET rates in many recent studies exceed fresh transfer rates because they allow the uterus to recover from stimulation before implantation. Pozitivf uses FET as the primary embryo transfer approach for patients with adequate embryos to freeze.

Realistic Expectations by Profile

Profile 1: 30-year-old with unexplained infertility, normal AMH (3.0+), partner with normal sperm.
– Per-cycle live birth rate: ~50%
– Three-cycle cumulative: ~85%
– Realistic plan: 1–2 cycles total, with embryos likely banked for siblings.

Profile 2: 36-year-old with PCOS, AMH 5.5, partner normal sperm.
– Per-cycle live birth rate: ~40%
– Three-cycle cumulative: ~75%
– Realistic plan: 1–2 cycles, with potential to bank embryos.

Profile 3: 39-year-old with diminished ovarian reserve, AMH 0.8, no other factors.
– Per-cycle live birth rate: ~15–20%
– Three-cycle cumulative: ~40–50%
– Realistic plan: 3–4 cycles, often with PGT-A. Donor egg consideration if cycles unsuccessful.

Profile 4: 33-year-old with severe male factor (TMSC 1 million), normal female workup.
– Per-cycle live birth rate: ~45% (with ICSI)
– Three-cycle cumulative: ~75%
– Realistic plan: 1–2 cycles, banking embryos.

Your consultation will produce a personalized estimate based on your actual workup, not a generic profile.

What “Success” Means — Definitions Matter

Different clinics and reports use different definitions. When comparing rates, be sure you’re comparing apples to apples:

Clinical pregnancy rate: Detectable pregnancy on ultrasound (gestational sac with heartbeat). This is the highest reported number and is not the same as a live birth.
Live birth rate: Pregnancy carried to delivery of a live baby. This is the meaningful number for patients.
Per-cycle rate vs. per-transfer rate: “Per-cycle” includes cycles where no transfer happened (no embryos to transfer). “Per-transfer” only counts cycles where an embryo was transferred — making this number higher.
Cumulative rate: Includes all transfers (fresh + frozen) from a single egg retrieval. This is often the most patient-relevant number.

Pozitivf reports live birth rate per embryo transfer as the primary outcome measure, with secondary reporting on cumulative rate per egg retrieval.

How to Compare Clinics Honestly

If you’re evaluating multiple Texas fertility clinics, ask each for:

Live birth rate per embryo transfer by age group, sourced from SART or CDC reporting (not from clinic marketing materials).
Cumulative live birth rate per egg retrieval for the past two reporting years.
Diagnosis mix of their patient population (a clinic that primarily treats young, healthy patients will look better on paper than one that treats complex cases).
Single embryo transfer (SET) rate — higher SET rates indicate clinical responsibility around twin/triplet risks.
Whether clinic publishes outcomes by SART standards. A clinic that does not report to SART or refuses to discuss methodology is a red flag.

Frequently Asked Questions

Why do success rates vary so much between clinics?
Patient mix is the biggest variable. A clinic treating mostly young, good-prognosis patients will have higher rates than one treating older or more complex cases. Embryo transfer policy (single vs. dual) and PGT-A use also affect reported rates.

What’s the difference between SART rates and CDC rates?
SART (Society for Assisted Reproductive Technology) is an industry organization that publishes voluntary clinic-by-clinic outcomes. CDC’s ART National Summary is mandatory federal reporting. Both use similar methodology but SART is updated more frequently and offers detailed clinic comparisons.

Does insurance affect success rates?
Not directly. But clinics that primarily serve insurance-covered patients may have different demographics (often younger, more aggressive treatment) compared to clinics like Pozitivf that primarily serve self-pay patients. The medical outcomes themselves are based on biology, protocols, and lab quality — not payment method.

What is a “good” success rate for IVF?
For a 35-year-old with a favorable diagnosis, a live birth rate per transfer of 40% or higher is in line with national leading clinics. For patients 38+, 25%+ per transfer with own eggs is reasonable. The most important comparison is your specific age and diagnosis against published benchmarks.

Does Pozitivf publish individual cycle outcomes?
We are building a multi-year dataset and will publish detailed outcomes by SART standards starting with the 2026 reporting cycle. In the interim, your consultation with Dr. Arredondo will include a personalized estimate based on national benchmarks adjusted for your specific factors.

What if my cycle fails?
Pozitivf does not offer money-back guarantees on IVF (the few clinics that do typically charge significantly more upfront to cover the guarantee). If a cycle fails, Dr. Arredondo will review what happened (egg/embryo quality, response to stimulation, transfer conditions) and recommend next steps — which may be a protocol adjustment for the next cycle, escalation to PGT-A, or consideration of donor egg.
