TESA (Testicular Sperm Aspiration)

It is a procedure in which a needle is inserted into the testicle and small tissues are removed by aspiration to obtain sperm. Sometimes an open testicular biopsy may be needed if this procedure does not provide enough tissue or sperm. It is performed under local anesthesia and since the needle is applied without seeing through the skin, it brings risks such as not obtaining sperm or obtaining a small number of sperm and bleeding.

Who is it applied to?

Men who have had a vasectomy (vasectomy: a surgical contraceptive method in which the sperm ducts are cut, tied or sealed)

Obstructive azoospermia due to infection

Obstruction due to trauma or previous surgery

Those with undescended testicles

Previous infection (mumps)

Those without congenital vas deferens (sperm ducts). It is especially seen in cystic fibrosis carriers.
