Oocyte cryopreservation

Oocyte cryopreservation (commonly referred to as OC or egg freezing) is a form of assisted reproductive technology (ART) used to preserve human eggs (oocytes). The technique is often used to protect against future infertility or delaying childbearing: when pregnancy is desired, the eggs can be thawed, fertilized, and transferred to the uterus as embryos. The procedure's success rate varies depending on factors such as the individual's age (with higher odds of success in younger individuals), overall health, and genetic factors. The first human birth of oocyte cryopreservation was reported in 1986. Although embryo cryopreservation is the most established method of fertility preservation, oocyte cryopreservation is often the best option for single reproductive-age women in need of delaying childbearing for any reason.
