BACKGROUND: Although few studies have reported fertility outcomes, no study has reported risk factors that might predict sperm retrieval and pregnancy in azoospermic men with a history of cryptorchidism in a large series.
OBJECTIVES: To investigate fertility outcomes and predictors for successful sperm retrieval and pregnancy in azoospermic men with a history of cryptorchidism who underwent microdissection testicular sperm extraction (mTESE).
MATERIALS AND METHODS: This retrospective observational study included 327 azoospermic men with a history of cryptorchidism who underwent mTESE. Fertility outcomes including sperm retrieval, fertilization rate, number of transferred embryos, pregnancy, miscarriage, and live birth rates were recorded.
RESULTS: Sperm retrieval was observed in 172 (52.6%) of the patients. The mean fertilization, pregnancy, and live birth rates were 55.2%±20.5, 53.5%, and 44.8%, respectively. The sperm retrieval rate was significantly higher at the orchidopexy age of ≤ 9.5 years (70.8%) than the orchidopexy age of > 9.5 years (42.1%) (P = .000). Patients with total testicular volume of ≥ 13.75 mL had significantly higher sperm retrieval rate (65.2%) than the patients with total testicular volume of < 13.75 mL (45.5%) (P = .001). Patients with total testosterone level of ≥ 300.5 ng/dL had significantly higher sperm retrieval rate (65.6%) than the patients with total testosterone level of < 300.5 ng/dL (40.3%) (P = .000). Patients with follicle-stimulating hormone (FSH) level of ≤ 17.25 mIU/ml had significantly higher sperm retrieval rate (72.3%) than the patients with FSH level of > 17.25 mIU/mL (44.4%) (P = .000). Younger male and female ages, and higher fertilization rates were the parameters that might predict pregnancy.
CONCLUSIONS: Infertile azoospermic men with a history of cryptorchidism have high sperm retrieval rate with mTESE. Patients who had orchidopexy at the age of ≤ 9.5 years, and having total testicular volumes of ≥ 13.75 mL with total testosterone level of > 300.5 ng/dL and FSH level of ≤ 17.25 mIU/mL have higher success rate for sperm retrieval.
