Objective: To analyze the characteristics of the males undergoing autologous sperm preservation (ASP), and provide some reference for human sperm banks to offer targeted service for those undergoing ASP.
Methods: We statistically analyzed the demographic features, reasons for ASP, and other relevant factors of the men applying for ASP in Chongqing from January 2016 to December 2019.
Results: Within 4 years, a total of 76 males applied for ASP, of whom about 63.2% came from Chongqing, 52.6% were aged 20－30 years old, 51.3% were undergraduates or above, 36.8% worked in government offices and public institutions, 61.9% were unmarried, nearly 80% acted by the doctor's advice, and 59.2% did it due to diseases, mainly including testis cancer, lymphoma and colon cancer, particularly before radio- or chemotherapy. Testicular sperm extraction (TESE) was successfully performed in 61 (80.3%) of the males. Of the 355 semen samples obtained, 83.1% were found with normal semen parameters, 60.5% cryopreserved successfully, and 4.3% of the frozen samples used for assisted reproduction.
Conclusions: ASP is comparatively a novel practice, with only a few participants. Full use of the aggregation characteristics of the population undergoing ASP should be made, and targeted service provided for the key subjects identified so as to benefit more people in need.
