Microsurgical testicular sperm extraction (microTESE)
Microsurgical testicular sperm extraction (microTESE) – A surgical procedure used to retrieve sperm from the seminiferous tubules of a male’s testes. It’s used for men with non-obstructive azoospermia, which is when a man cannot produce enough sperm to have a detectable amount in his semen — a common cause of male infertility. Doctors will usually recommend microTESE in these cases:
- If a man has an adequate level of testosterone in his blood after a hormone test and has other exams indicating that his testicles are not making normal amounts of sperm.
- If a man remains azoospermic even though he has received treatment and his testosterone levels have been normal for at least four months.
