Skip sharing on social media links
Share this:

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.

Vasectomy is one of the most effective forms of birth control. 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.
