Female and Male Sterilisation

What is female and male sterilisation?

The fallopian tubes (carry an egg from the ovary to the womb) in women are cut, sealed or blocked. The vas deferens (the tube that carries sperm from the testicles to the penis) in men are cut, sealed or blocked.

How effective are they?

  • The failure rate of female sterilisation is 1 in 200.
  • The failure rate for male sterilisation is 1 in 2000.


  • Sterilisation is permanent with no long or short term serious side effects.
  • It does not interrupt sex.


  • Should not be chosen if you have any doubts about having children in the future.
  • It takes at least two months for male sterilisation to be effective.
  • It does not protect you against Sexually Transmitted Infections.
