Testicular Sperm Extraction TESE
Testicular sperm aspiration (TESA) is a procedure performed for men who are having sperm retrieved for in vitro fertilization/intracytoplasmic sperm injection (IVF/ICSI). It is done under general anaesthetic in the operating room or with LOCAL anaesthetic in the office, and is coordinated with their wife’s egg retrieval.
Non-obstructive azoospermia (or abnormal sperm production) is a very common cause of male infertility. We usually recommend microsurgical testicular sperm extraction (microTESE) for non-obstructive azoospermia for these reasons:
· If a man has an adequate level of testosterone in sperm test results*
· If he has had testosterone levels corrected for at least four months and remains azoospermic
Sperm is found approximately 70% of the time in the micro TESE procedure.
