Due increasing of cancer among young women, the risk of premature ovarian insufficiency with subsequent infertility has been raised. Fertility preservation restores reproductive potential along with increasing life expectancy in these patients. Given the articles on new options in the treatment of cancerous women, we searched the keywords including fertility preservation, in vitro maturation, and ovarian cryopreservation. This review focuses on the currently available procedure including in vitro maturation (IVM) of retrieved immature oocytes, oocyte, embryo, and ovarian tissue (OT) cryopreservation. OTC was a useful procedure that allows restoring ovarian function and natural pregnancy. Also, we summarized the literature that reported the qualification of using the aforementioned procedures, comparing the cryopreservation methods including vitrification and slow freezing. Due to the impressive clinical development of OTC in cancerous patients, it is recommended as a standard treatment in cryopreservation strategy.
