Vasectomy (Male sterilization)

   A vasectomy is a form of male sterilization that involves surgically cutting or blocking the vas deferens, the tubes that carry sperm from the testicles to the urethra. This procedure is a permanent method of birth control and is considered a highly effective and safe form of contraception.

​

   During a vasectomy, a small incision is made in the scrotum, and the vas deferens is cut, tied, or sealed to prevent the release of sperm during ejaculation. The procedure can be performed under local anesthesia in a doctor's office or clinic and typically takes less than 30 minutes to complete.

​

   After a vasectomy, it may take several months and several ejaculations for all remaining sperm to clear from the vas deferens. Therefore, couples must use an alternative form of birth control until a follow-up sperm count confirms that no viable sperm remain.

​

   Vasectomy is a highly effective and safe form of contraception, with a failure rate of less than 1%. It does not affect a man's sexual function or libido, and there is no change in the appearance or sensation of ejaculation. However, it is important to note that vasectomy does not protect against sexually transmitted infections.
