Microdissection TESE: Finding Sperm When It Matters Most

mTESE is a highly specialized surgery used to find sperm in men with non-obstructive azoospermia (NOA) - a condition where no sperm is found in the semen. By carefully identifying and extracting the few sperm-producing tubules in the testicle, this technique gives many men the opportunity for biological parenthood.

What is mTESE?

Microdissection testicular sperm extraction (mTESE) is a surgical technique that uses a high-powered operating microscope to locate and retrieve sperm directly from testicular tissue. It’s often used when no sperm is found in a semen sample due to severely impaired sperm production.
