How Does a Vasectomy Work?

a vasectomy

A vasectomy is a surgical procedure to cut or seal the tubes that carry a man’s sperm to permanently prevent pregnancy. It is usually carried out under local anaesthetic, where you are awake but don’t feel any pain, and takes about 15 minutes. In rare cases, you may have a general anaesthetic, where you are asleep during the operation.

 

Quick Facts About a Vasectomy

  • A vasectomy is more than 99% effective.
  • It is considered permanent, so once it is done you don’t have to think about contraception again.
  • It doesn’t affect your sex drive or ability to enjoy sex. You will still have erections and ejaculate, but your semen won’t contain sperm.
  • You will need to use contraception for at least 8 to 12 weeks after the operation because sperm will still be in the tubes leading to the penis.
  • Up to 2 semen tests are done after the operation to make sure that all the sperm have gone.
  • Your ball sack may become bruised, swollen, or painful – some men have ongoing pain in their testicles.
  • As with any surgery, there is a small risk of infection.
  • You can reverse a vasectomy however this is a more difficult procedure, so be sure it is right for you.
  • A vasectomy doesn’t protect against sexually transmitted infections, so you may need to use condoms as well.

How it Works

A vasectomy works by stopping sperm getting into a man’s semen, the fluid that he ejaculates. The tubes that carry sperm from a man’s testicles to the penis are cut, blocked or sealed with heat. This means that when a man ejaculates, the semen has no sperm in it and a woman’s egg cannot be fertilised.
