A case of azoospermia due to genitourinary tuberculosis is reported with discussion on the treatment of infertility in such a case. A 38-year-old man visited us complaining of 4-year sterility. We suspected obstructive azoospermia due to previous genitourinary tuberculosis because of his treatment history, calcifications in the seminal vesicles and nodules in the right epididymis. After microsurgical epididymal sperm aspiration (MESA) was performed twice without success, we extracted sperm from his testis (testicular sperm extraction, TESE) and fertilized his wife's egg by intracytoplasmic sperm injection.
