Success rates vary significantly by clinic. A clinic with strong lab quality and experienced embryologists can improve your individual odds beyond national averages. We're building a clinic directory with verified SART data and real patient reviews.

What affects IVF success rates?
A woman's age at egg retrieval is the single biggest factor. Egg quality and quantity decline with age. Women under 35 have significantly better outcomes than women 38 and older. This is why many doctors recommend freezing eggs before 35 if you're planning to delay childbearing.
Anti-Mullerian Hormone reflects the number of egg follicles remaining. A higher AMH means more eggs are available to retrieve per cycle, which increases the chance of having at least one viable embryo. Very low AMH (under 0.5 ng/mL) may mean fewer eggs retrieved per cycle, though egg quality is still primarily determined by age.
Obesity (BMI above 30) is associated with lower IVF success rates — roughly a 5–10% reduction in live birth probability per cycle. This is thought to be related to hormonal imbalances and reduced embryo implantation rates. Being underweight (BMI below 18.5) also slightly reduces success rates. A BMI between 20–27 is generally considered optimal for fertility treatment.
The reason for IVF matters. Male factor infertility and unexplained infertility tend to have better outcomes because the female partner's eggs and uterus are typically healthy. Diminished ovarian reserve and uterine factors tend to have lower success rates. PCOS and tubal factor are intermediate.
Having had a prior pregnancy or live birth is a positive prognostic sign — it demonstrates that implantation and pregnancy can occur. This is a moderate positive factor in the model.
Methodology
This tool uses the SART 2022 National Summary Report's published live birth rates per egg retrieval cycle, stratified by patient age band. It then applies evidence-based adjustment multipliers for BMI, AMH level, infertility diagnosis, and pregnancy history.
This is a simplified approximation. SART's own published predictor uses a proprietary regression model trained on patient-level records from thousands of U.S. clinics. Our model uses aggregate statistics and published research on modifier effect sizes.
