Fertility Success Rates
Since reported pregnancy success rates from established programs may vary, it is important to understand how various statistics are computed and presented. Efficacy rates depend not only on the skills of the practitioners, but on individual patient characteristics such as age, indication for IVF and number of eggs retrieved and fertilized. Reported results may include patients of all ages and indication, or they may be categorized by age and indication.
Our pregnancy success rates are tracked for both clinical pregnancy/transfer and for liveborn/transfer. We disaggregate our results by age group as well as by IVF success rates, egg donor success rates and cryopreservation (egg freezing) successes. In an effort to reduce the risk of triplet and quadruplet pregnancy, we limit the number of embryos transferred to 2 below age 38 in most cases. This has been successful in reducing the multiple pregnancy risk, while at the same time maintaining high pregnancy rates.
