Extracting Sperm Before and After Cancer Treatment

VIDEO | 6:00

Dr. John Mulhall, director of the Male Sexual and Reproductive Medicine Program at Memorial Sloan Kettering Cancer Center, describes a 10-minute procedure called electroejaculation, which is used to extract sperm from men or boys who are unable to ejaculate on their own. Doctors may use another procedure, called testicular sperm extraction (TESE), to obtain sperm from testicular tissue in men who undergo electroejaculation but produce poor-quality or low concentrations of sperm. Nearly half of cancer patients who undergo TESE can later have intracytoplasmic sperm injection (ICSI), in which sperm is injected into an egg to form an embryo.
