PESA (Percutaneous Epididymal Sperm Aspiration)
PESA is a procedure performed for men who are having sperm retrieved for in vitro fertilization/intracytoplasmic sperm injection (IVF/ICSI) who have obstructive azoospermia from either a prior vasectomy or infection. It is done with local anesthesia in the operating room or office and is coordinated with their female partner’s egg retrieval.
