Oocyte cryopreservation is a procedure to preserve a woman's eggs (oocytes). This technique is often used to delay pregnancy. When pregnancy is desired, the eggs can be thawed, fertilized, and transferred to the uterus as embryos. Several studies have shown that most infertility problems are due to germ cell deterioration related to aging.[1] The procedure's success rate varies depending on the woman's age (with higher odds of success in younger women), health, and genetic factors. The first human birth of oocyte cryopreservation was reported in 1986.[2]
