Microdissection TESE (microTESE) is a specialised surgical technique used to retrieve sperm from the testicular tissue. This procedure is recommended for men with non-obstructive azoospermia, where the testicular tissue is unable to produce sperm naturally.

We may recommend microTESE if you experience any of these conditions:

• You do not have ejaculated sperm, and there are no signs of blockage.
• You have an extremely low number of ejaculated sperm.
• You have tried other methods of sperm extraction that have failed.

The goals of the microTESE procedure are to:

• Obtain the best quality sperm.
• Get enough sperm to fertilize a healthy female reproductive cell (egg).
• Minimize damage to your reproductive organs.

During a microTESE procedure, the fertility specialist makes a small incision in your scrotum and, using a microscope, dissects and removes small samples of testicular tissue carefully. The sample tissues are then examined under a microscope to identify and retrieve any viable sperm.

MicroTESE is a more complex and delicate procedure than traditional TESE. It has a success rate of around 50% to 70% in men with non-obstructive azoospermia. Highly skilled fertility specialists generally perform it with extensive experience in microsurgical techniques.
