Often, couples have excess embryos after an in vitro fertilization (IVF) cycle that they have cryopreserved for future use. Embryo cryopreservation has become a routine practice within advanced reproductive technology (ART) clinics. Vitrification, which is the newer technology for embryo cryopreservation, has significantly improved the pregnancy outcomes achieved with frozen embryos compared to the older freezing methods. In fact, frozen embryo transfer cycle success rates are now equal to the success rates of fresh embryo transfer cycles.

During a frozen embryo transfer cycle, both estrogen and progesterone hormones are used to prepare the uterus to be more receptive. This hormonal preparation usually takes 3-4 weeks of time. During this 3-4-week period of time, we ensure optimal uterine receptivity by monitoring the hormone levels and the uterine lining. Cryopreserved embryos are then thawed and transferred back into the uterus. Approximately 95% of embryos will usually survive the freeze-thaw process. 10 days after the embryo transfer, pregnancy testing occurs.
