Vasectomy

A vasectomy (pronounced va-SEK-tuh-mee) is a surgical procedure performed as a method of birth control in men. It involves cutting the tubes (the vas deferens, pronounced VAS DEF-uh-renz) that carry sperm from the testicles.

Only about 15 of every 10,000 couples get pregnant in the year after the man has a vasectomy.

As part of a program of research on the safety and effectiveness of male contraceptives, the NICHD supports studies and other activities advancing understanding of vasectomy.
