IVF Success Rates

Making sense of IVF success rates

We are proud of the Reproductive Science Center of the San Francisco Bay Area’s record of success. RSC of the SF Bay Area 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 are constantly staying abreast of the latest clinical trends in vitro fertilization or other infertility treatments. Our embryologists are experts in their field, who follow the latest laboratory protocols and ensure we offer state-of-the-art equipment and facilities.

As we continue to improve our pregnancy rates at RSC, we remain steadfast in promoting single embryo transfers (eSET) to reduce multiple pregnancies.

Learn about ESET

Our IVF success rates are very competitive nationally, and our donor egg and frozen embryo cycles are well 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.
