Research Progress of Ovarian Tissue Cryopreservation and Transplantation

Age, disease and anti-tumor treatment may cause the decline or even loss of female fertility. Embryo cryopreservation, oocyte cryopreservation and ovarian tissue cryopreservation are commonly used at present. Cryopreservation and transplantation of ovarian tissue has become a fertility preservation method with medical indications in clinic, which is helpful for patients to successfully complete fertility through this technology. This paper reviews the international research progress on ovarian cryopreservation and transplantation in recent years. Despite the rapid development of ovarian tissue cryopreservation and transplantation technology, it still faces challenges such as how to reduce the loss of follicular reserve and thus prolong the effectiveness of ovarian tissue transplantation. More basic and clinical research is needed to promote the progress and development of ovarian tissue cryopreservation and transplantation technology.
