Vasectomy

A vasectomy is a male sterilization surgery that involves snipping the vas deferens, which is the reproductive tube that carries sperm from a male's epididymis all of the way to this man's prostate. More than 500,000 men each year in the U.S. get vasectomies for birth control purposes, and one out of every 2,000 vasectomies subsequently ends up failing.
