Abstract
A 15-year-old female with Hodgkin's lymphoma underwent ovarian tissue cryopreservation for preserving fertility in Reproductive Department of Sir Run Run Shaw Hospital, Zhejiang University School of Medical after receiving one course of chemotherapy. During the ovarian tissue cryopreservation, one MⅡmature oocyte and three germinal vesicle oocytes were found. The three immature oocytes underwent in vitro maturation but failed. Ultimately, one mature oocyte and 12 ovarian cortex slices were cryopreserved using vitrification. This case indicates that for patients with established gonadal axis feedback, ovarian tissue cryopreservation may not be the only method for fertility preservation. It is advisable to consider ovarian stimulation and oocyte retrieval for oocyte cryopreservation. Alternatively, for individuals in the ovulation phase of their menstrual cycle, attempting oocyte retrieval before ovarian tissue cryopreservation to obtain mature oocytes from the natural cycle, followed by oocyte cryopreservation, may enhance the likelihood of successful fertility preservation.
