IVF Success Rates

We are proud of the Reproductive Science Center of the San Francisco Bay Area’s record of success. RSC is fortunate to have experienced doctors whose pioneering efforts in IVF have helped create many families since we were founded in 1983. In addition, our doctors and IVF laboratory staff alike are constantly improving their skills and our state-of-the-art facilities to increase your likelihood of becoming a parent through in vitro fertilization or other infertility treatments.

As we continue to improve our pregnancy rates at RSC, we remain steadfast in promoting single embryo transfers to reduce multiple pregnancies. In 2012, 31 percent of women using their own embryos – 38 years of age and younger – elected to transfer one egg while the clinical pregnancy rate was 61 percent. For the same year, 49 percent of women using donor eggs elected single embryo transfer resulting in a clinical pregnancy rate of 73 percent.

Our IVF success rates are very competitive nationally, and our donor egg and frozen embryo cycles are above national average in live births per transfer. These numbers represent our high standard of treatment excellence, which gives you a better chance of successfully conceiving and taking home a baby.  These statistics only apply to retrievals and transfers performed by RSC physicians. Please contact your infertility practice to discuss their success rates.

Please read Making Sense of ART Statistics to help you understand the meaning of these statistics.

The statistics below represent the most up-to-date information from the Centers for Disease Control and Prevention (CDC) and the Society for Assisted Reproductive Technologies (SART), which collect and report statistics for U.S. fertility clinics.

NOTE: “A comparison of clinic success rates may not be meaningful because patient medical characteristics, treatment approaches and entrance criteria for ART may vary from clinic to clinic.”

* Cycles with retrieval but no transfer due to freeze because of:

1. Planned PGS cycle (most)
2. OHSS
3. This uterine lining
