Objective:
This article reports the second live birth in China after frozen-thawed ovarian tissue transplantation to prevent iatrogenic premature ovarian insufficiency (POI).
Method:
A patient with aplastic anemia received ovarian tissue cryopreservation before hematopoietic stem cell transplantation, and four ovarian cortex strips were thawed and transplanted into her peritoneal pocket 18 months later.
Results:
Pregnancy occurred spontaneously 5 years after grafting, and a healthy girl was born at 39 weeks of gestation. Until now, the child has developed normally without any major diseases.
Conclusion:
Ovarian tissue cryopreservation and transplantation (OTCT) can be assessed as a successful method especially to prevent iatrogenic POI. In our cryobank for OTCT, which is the first official one in China, intensive research to improve this method has been performed, and we propose after our success for the second pregnancy in China to include this method in the official guidelines for prevention and treatment of (especially iatrogenic) POI.
