Question: a man has a vasectomy?
Answer: Vasectomy is minor surgery to block sperm from reaching the semen that is ejaculated from the penis. Semen still exists, but it has no sperm in it. After a vasectomy the testes still make sperm, but they are soaked up by the body. Each year, more than 500,000 men in the U.S. choose vasectomy for birth control.
