Fertility outcomes and predictors for successful sperm retrieval and pregnancy in 327 azoospermic men with a history of cryptorchidism who underwent microdissection testicular sperm extraction.

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.
