Male Sterilisation (Vasectomy)

A permanent method of contraception, where the tubes (vas deferens) that carry sperm from the testicles to the penis are cut, sealed, or tied.

Overall failure rate is 1 in 2000



  • Not easily reversed
  • Once it has worked, you do not have to use contraception again
  • Usually performed under local anaesthetic


  • Contraception must be used until a semen test shows no sperm are left
  • Some people may experience ongoing testicle pain, but this is uncommon
  • No protection against STI’s


  • Needs careful consideration/counselling to ensure there is no doubt that this is the best method prior to the operation
  • May experience discomfort/pain after sterilisation
