Female sterilisation

Female sterilisation


Other names: tubal occlusion


What is female sterilisation?

Female sterilisation, also known as tubal occlusion, is an procedure permanently prevent pregnancy and involves cutting, sealing, or blocking the fallopian tubes which carry an egg from the ovary to the uterus (womb). It is a non-reversible form of birth control, so it is only a choice for women who never want to have children, or who don't wish to have any more.


A note on gender


Gender identification is a personal journey. Not everyone with a male body is a man and not everyone with a female body is a woman. This information is for people of all genders including transgender, non-binary and intersex individuals.

Female sterilisation


Female sterilisation is a type of permanent method of contraception


Female sterilisation belongs to a category of contraception known as permanent contraception. These methods are permanent and can’t usually be reversed.

How does female sterilisation prevent pregnancy?


During female sterilisation, the fallopian tubes (the tubes that carry the eggs) are blocked or sealed.


This prevents the eggs from reaching the sperm and becoming fertilised.

How effective Is female sterilisation?

Apart from abstinence, female sterilisation is the most effective method of contraception. Female sterilisation is more than 99% effective at preventing pregnancy. It’s rare for a tubal occlusion to fail. Sterilisation may fail if the tubes that carry the sperm or eggs rejoin, straight away or some years later.

    No. Female Sterilisation is hormone-free.

    Sterilisation should only be considered by women who do not want any more children or do not want children at all. You may also want to explore whether another method of contraception which is also highly effective may suit you, such as long-acting reversible contraception (LARC) like an implant, IUS or IUD.
