Abstract: The methods of female fertility preservation includes embryo cryopreservation, occyte freezing and ovarian tissue cryopreservation. The embryo freezing technology has been well developed with the survival rate over 90%. The oocyte freezing technology has also yielded progress in recent years. The ovarian tissue cryopreservation and transplantation has a predominance in the preservation of both endocrine function and reproductive function. Currently, human ovarian transplantation mainly consists of the orthotopic and heterotopic transplantation of fresh or cryopreserved ovarian tissue. The factors related to ovarian transplantation include the process of cryopreservation, transplantation site and pretreatment before transplantation, etc. With the increasingly improved technology of organ freezing and microsurgery, cryopreservation and transplantation of whole ovary have been the trend of ovarian preservation. However, the whole ovary transplantation is still at the stage of animal experiments. There are not the standard procedure of cryopreservation and thawing. The research progress of ovarian cryopreservation and transplantation was reviewed.
