PESA is a procedure performed for men who are having sperm retrieved for 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 is aspirated. TESA is performed for men with obstructive azoospermia (s/p vasectomy). Occasionally, TESA doesn’t provide enough tissue/sperm and an open testis biopsy is needed.
