Success Rates

Shady Grove Fertility offers three types of anonymous donor egg treatment options including the traditional one donor to one recipient option as well as shared donor options where one donor is shared between one or two other recipient couples. The shared options are designed to reduce the cost of treatment by spreading the expenses between two or three couples.

But what impact does egg sharing have on success rates?

Extensive retrospective research of over 800 donor egg cycles proved that one donor typically produces enough eggs (12 on average) to share among two to three recipients without compromising success rates. While this was our theory, based on good solid data and scientific evidence, it has also played out in actual success rate data based on over 2,000 shared donor cycles that have been performed from since 2007. Today, four out of five couples are choosing the Shared Donor Egg options over traditional donor egg.

Elective Single Embryo Transfer vs. Multiple Embryo Transfer

Physicians at Shady Grove Fertility are leaders in the field of infertility in promoting elective Single Embryo Transfer (eSET). By electing to transfer one blastocyst instead of two in patients with good prognosis, our data demonstrates that twin pregnancy, with its greater risk to mother and infants, can be nearly eliminated without compromising pregnancy success rates.
