Sterilisation

What is it?

Sterilisation is a permanent method of contraception, which works either by blocking the woman's fallopian tubes (the tubes in which the egg travels from the ovary to the womb) or by blocking the man's vas deferens (vasectomy), (the tube that sperm travel in from the testicles to the penis).

Sterilisation is only suitable for people who are sure they never want children or do not want any more children.

There are other long-term methods of contraception which are as effective as sterilisation but not permanent. Ask your doctor, nurse or sexual health staff for advice.

How effective is sterilisation?

Male sterilisation (vasectomy) - About 1 in 2,000 male sterilisations fail.

Female sterilisation - About 1 in 200 sterilisations fail.

There is always a risk that sterilisation will fail. The tubes can rejoin after sterilisation. This can happen immediately or years after the operation has taken place. If you ever believe a pregnancy is possible, see a doctor or nurse as soon as possible.

Where can I go for information on sterilisation?

Your GP or practice nurse can all give you advice on sterilisation. If you prefer not to use your own GP, or they don't provide contraceptive services, you can come to your local Sandyford clinic. All treatment is confidential and free.


What are the advantages of sterilisation?

  • It does not interrupt sex.
  • After being sterilised you do not have to use any contraception to prevent pregnancy. Although you may still want to use condoms to protect you from sexually transmitted infections.


What are the disadvantages of sterilisation?

  • Although uncommon tubes may rejoin and you will become fertile again.
  • Reversal of sterilisation has a low success rate and is not available on the NHS.
  • Sterilisation does not protect you against sexually transmitted infections.
  • It takes a minimum of 3 months for a male sterilisation to be effective.
