Since in a typical IVF cycle, multiple embryos are created and our standard of care is elective single embryo transfer (eSET), there is usually a surplus of embryos. These embryos, if viable and of adequate quality, can be frozen for future use in a frozen embryo transfer (FET) cycle.
Pregnancy rates are significantly higher in women who undergo a frozen embryo transfer cycle using embryos that have undergone PGT-A compared to fresh embryos. This allows for the transfer of a single embryo, thereby reducing the risk of multiple pregnancies. Multiple pregnancies increase the risk of complications for the mother and fetus. Remaining frozen embryos can also be used for subsequent pregnancies thereby reducing the overall cost for each pregnancy attempt.
Other reasons for cryopreservation of embryos include freezing all embryos in patients concerned that their future fertility potential might be reduced due to necessary medical treatment (e.g., cancer therapy or surgery).
