Oocyte cryopreservation

ICSI sperm injection into oocyte

Oocyte cryopreservation is a procedure to preserve a woman's eggs (oocytes). This technique has been used to postpone 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 age of the woman, (with the odds of success being higher in younger women), as well as depending on health and genetic indicators. In 1986, the first human birth of oocyte cryopreservation was reported.
