Success Rates

Our patients achieve pregnancy at rates consistently higher than the national average.

With more than 30 years of advanced fertility care, the Washington University Fertility and Reproductive Medicine Center is the region’s trusted source in developing precise fertility treatment options that consistently lead to high success rates.

All of our physicians are fellowship-trained, board-certified reproductive endocrinologists. In fact, the Washington University Fertility and Reproductive Medicine Center is the only clinic in the St. Louis area providing in vitro fertilization (IVF) that is a member of the Society for Assisted Reproductive Technology (SART). SART membership requires we meet the highest standards of quality, safety and patient care.

Our IVF pregnancy rates are higher than the national average

Our pregnancy rates continue to be the highest in the St. Louis region, whether examining live birth rate, pregnancy rate per cycle, or pregnancy rate per transfer*. Our success rates also continue to be higher than the national average.

Common questions

Do you have any questions not answered below? Please let us know.

How do you measure success?

IVF success rates can be difficult to compare. In addition to variations in each patient’s age, overall health and infertility factor, treatment approaches may differ from clinic to clinic.

Still, pregnancy rates among women who are 35 years and younger can serve as a benchmark for comparing the success rates of multiple clinics. We can examine this by looking at the Centers for Disease Control and Prevention (CDC) Assisted Reproductive Technology reports by clinic.

How do age and diagnosis affect IVF success?

Age is still the best predictor of success with IVF. As a result, pregnancy rates are highest among women who are age 37 and below. Pregnancy rates using one’s own eggs decline significantly after 41. Using donor eggs provides a greater chance of success.

Why is live birth rate lower than pregnancy rate?

Pregnancy rate is the percentage of cycles that results in a pregnancy that is seen on ultrasound. About 15% of pregnancies that are seen on ultrasound (aka: “clinical pregnancy”) can result in miscarriage. The most common cause of miscarriage is due to chromosomal abnormalities within the embryo.

How do I interpret a center’s multiple gestation rate?

Our center is committed to keeping the multiple gestation rate down, and our triplet and higher live birth rate is <1%. Our lab has become increasingly adept at using techniques that allow us to pick the embryo that is most likely to result in a live birth. As a result, patients under the age of 37 are eligible for having a single embryo placed to drastically reduce the rate of twins with little significant decrease in success.

What is ICSI and do I need it?

Intracytoplasmic sperm injection (ICSI) is a technique in which the sperm is directly injected into the egg. Evidence supports reserving this technique for couples dealing with male infertility. Some centers perform ICSI on all patients regardless of diagnosis. In general we reserve ICSI for male factor infertility.
