How it works

The tubes (vas deferens) that carry sperm from the testicles to the penis are cut, sealed or tied.

Usually performed under a local anaesthetic.

Contraception must be used until a semen test shows no sperm are left. This can take at least eight weeks.

  • Almost 100% effective.
  • This is a permanent method, suitable for people who are sure they never want children or do not want more children.
  • It does not interrupt sex.
  • Once the operation has worked, you don’t have to think about contraception.
  • It cannot easily be reversed.
  • Some men may experience on going testicle pain but this is not common.
    Treatment for this is often unsuccessful.
  • Should not be chosen if in any doubt, and counselling is important.
  • You may experience discomfort or some pain for a short time after sterilisation.

It is important to rest and avoid strenuous activity for a while after the procedure.
