What is TESA? It is a technique used to remove sperm directly from the testes.
When do you do TESA? For men who don’t have sperm in their semen (azoospermia) or have difficulty in collecting semen, TESA is performed. Commonly used for Obstructive Azoospermia – when something is stopping sperm from coming out.
(True Azoospermia is when there are no sperm being produced. This requires donor sperm)

*What is the difference between TESA and PESA?
If there is no sperm in the Epididymis during the PESA procedure, the needle is inserted into the testicle to collect the sperm. This is known as TESA.
