microdissection testicular sperm extraction (mTESE)

Microdissection testicular sperm extraction (mTESE) is a surgical procedure used to retrieve sperm directly from the testes in men with very low or no sperm in their semen. The process involves making a small incision and using a microscope to carefully examine the testicular tissue, identifying and removing only the areas likely to contain healthy sperm. This targeted approach maximizes sperm retrieval while minimizing tissue damage. mTESE is often employed for men with conditions like non-obstructive azoospermia, providing a chance for biological fatherhood when other methods have failed.
