Vasectomy for Male Sterilization

A vasectomy is a surgery that works to inhibit reproduction by interrupting the passage of sperm through the vas deferens, a tube in the male reproductive system. The procedure is a method of inhibiting an individual's ability to cause pregnancy through sexual intercourse without altering the other functions of the penis and testes. In the US, into the early 1900s, proponents of eugenics, the belief that human populations can be made better by selecting for so-called desirable traits, used the procedure to forcibly sterilize people whom they deemed undesirable. Despite its early associations with eugenics, physicians' use of vasectomy eventually transitioned into an option for elective contraception. Even with the various shifts in motivation for performing vasectomies, as of 2024, individuals have the choice to undergo a sterilization procedure if they want to restrict their own ability to have children.
