"vasectomy" の定義と意味

What is a "vasectomy"?

A vasectomy is a surgical procedure that makes men infertile by cutting or blocking the tubes that carry sperm from the testicles, known as the vas deferens. This procedure is typically performed as a permanent method of preventing pregnancy. During a vasectomy, a small cut is made in the pouch that holds the testicles, known as the scrotum, to access the vas deferens and either cut, tie, or block it to prevent sperm from entering the fluid released during ejaculation. This procedure does not affect sexual function or hormone production but prevents sperm from being released during ejaculation, thereby preventing pregnancy. While vasectomies can sometimes be reversed through another surgery, reversals are not always successful, and the chances of regaining fertility decrease over time. Therefore, even though a vasectomy is considered a safe and effective method of birth control with minimal complications, it should be carefully considered because it can be a permanent solution.
