Embryo Cryopreservation
What is Embryo Cryopreservation?
Embryo cryopreservation is the process of freezing and preserving embryos at an early stage, prior to implantation, to use for future pregnancies.
Who Should Consider Embryo Cryopreservation?
Patients undergoing IVF may consider embryo cryopreservation if they wish to attempt pregnancy in the future or avoid repeating a full IVF cycle. Additionally, those with extra embryos after a successful IVF may store them for future use or donation.
Methods of Embryo Cryopreservation
Embryo freezing can be done via two primary methods: vitrification and slow programmable freezing (SPF). Vitrification, a rapid-freezing technique, helps reduce DNA damage compared to slower freezing methods.
Pregnancy Outcomes with Frozen Embryos
Research shows that using cryopreserved embryos does not increase the risk of birth defects or developmental abnormalities. In fact, frozen embryo transfers are associated with higher pregnancy rates and improved perinatal outcomes compared to transfers done during the ovarian stimulation cycle.
