Obstructive Azoospermia

Obstructive Azoospermia occurs when sperm is being produced in the testes but cannot be found in the semen because of a blockage in the male reproductive tract. In most cases of obstructive azoospermia, sperm can still be retrieved by a form of surgical sperm retrieval or SSR procedure such as Testicular Sperm Aspiration or TESA.

Causes of obstructive azoospermia can include sexually transmitted disease, scar tissue, congenital or genetic conditions or previous surgeries.
