A vasoectomy, more commonly referred to as a vasectomy, is a surgical procedure for male sterilization that involves cutting and sealing the vas deferens, the tubes that carry sperm from the testicles to the urethra. This procedure prevents sperm from mixing with semen during ejaculation, effectively preventing pregnancy. Vasectomies are usually considered a permanent form of contraception, though reversal is possible in some cases. The procedure is typically quick, minimally invasive, and performed under local anesthesia.
