Testicular Sperm Aspiration (TESA)
Is a procedure done for men who are having sperm retrieved for in vitro fertilization/intra-cytoplasmic sperm injection (IVF/ICSI).It is done with local anesthesia in the operating room and is done at the same time with their female partner’s egg retrieval. A needle is inserted in the testicle and tissue/sperm are aspirated. TESA is done for men with obstructive azoospermia or who had vasectomy. If TESA doesn’t provide enough tissue/sperm, an open testis biopsy is needed.
