High cumulative live births in oocyte donation cycles with cryopreservation of all embryos.

Background: Cryopreservation of all embryos in stimulated IVF cycles is occasionally necessary. Although it is known that frozen embryo transfer results in lower live birth rates per transfer, there is limited information regarding expected cumulative live birth rates for patients who are in this particular scenario.

Methods: The objective was to evaluate long-term outcomes in cycles undergoing pronuclear cryopreservation of all embryos utilizing a retrospective analysis of 154 consecutive recipients from 1995 to 2006.
