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 prevents sperm from mixing with semen during ejaculation, effectively rendering the man infertile. The procedure is typically considered a permanent form of Birth Control, although reversals can be attempted in some cases. It is usually performed under local anesthesia and has a relatively quick recovery time.
