TESA (TEsticular Sperm Aspiration)

Testicular sperm aspiration (TESA) is a procedure performed for men who are having sperm retrieved for in vitro fertilization/intracytoplasmic sperm injection (IVF/ICSI). It is done with local anesthesia in the operating room or office and is coordinated with their female partner’s egg retrieval. A needle is inserted in the testicle and tissue/sperm are aspirated. TESA is performed for men with obstructive azoospermia (s/p vasectomy). Often TESA doesn’t provide enough tissue/sperm and an open testis biopsy is needed.
