A vasectomy is a surgical procedure for permanent male contraception. It involves cutting or sealing the vas deferens, the tubes that carry sperm from the testicles to the urethra, preventing sperm from being ejaculated during sexual intercourse.
While it doesn’t affect a man’s ability to produce semen or have sexual pleasure, it makes him sterile, as sperm can no longer reach the ejaculate.
Vasectomy is a safe and effective method of birth control and is considered permanent, although reversal procedures are available but may not always be successful.
