Success Rates

Conceptions has consistently achieved among the highest IVF pregnancy rates in the United States.

Since 1992, IVF clinics in the U.S. have been required to report their pregnancy and live birth rates for all assisted reproductive technology (ART) cycles to the Center for Disease Control (CDC). The CDC tracks this information and publishes it annually.

The most currently available live birth rates (LBR) are from 2017.

A Better IVF Protocol

The Conceptions CCS IVF program, pioneered at Conceptions Reproductive Associates, offers the most effective evaluation, assessment, and treatment options in a single IVF cycle. Following this protocol, we are able to achieve among the highest success rates available at any fertility clinic in the world.

It is cost effective in comparison to the multiple cycles often required to achieve success at other centers, and provides greater insight about your fertility. The Conceptions CCS IVF program is a cost effective way to take home a healthy baby.
