Testicular sperm aspiration (TESA), is a method where sperm is retrieved directly from the testicles and is commonly used for men with non-disruptive azoospermia. With this condition, no sperm can be retrieved from the epididymis.

It involves passing a fine needle through the skin directly into the testes and retrieving a small number of the seminiferous tubules themselves. The tubules are then dissected in the laboratory and the contents searched for the presence of sperm.

This procedure can be performed under either local anaesthetic or sedation.
