Abstract：Ovarian tissue vitrification and transplantation techniques are crucial for fertility preservation,especially for young women with the cancer requiring gonadotoxic treatments and for prepubertal children.This technique involves multiple factors that affect the outcomes of cryopreservation and transplantation.In terms of cryoprotectant selection,the composition,concentration and equilibration time have significant effects on the freezing outcome.The processing of ovarian tissue and the choice of freezing carrier are also crucial factors influencing the success of cryopreservation and transplantation.During thawing and recovery,the removal rate of cryoprotectants must be carefully controlled to prevent cellular damage.The choice of transplantation site can be determined,based on the patient's actual needs.Ischemia,hypoxia and oxidative stress during the initial period after transplantation are important factors leading to follicular loss,which can be improved by the use of angiogenic factors,stem cells,antioxidants,and other interventions.Additionally,clinical factors such as the age,number of transplantations and mode of conception can also impact the pregnancy rates following transplantation.These factors provide a scientific basis and practical guidance for optimizing the success rate of ovarian tissue cryopreservation and transplantation,offering new insights and directions for future research and clinical practice.
