Sterilisation and vasectomy

A vasectomy is not reliable contraception immediately after the procedure. Another method is needed until follow-up confirms that it has worked. Both vasectomy and sterilisation are intended to be permanent. Take time to discuss the decision and follow-up plan before surgery.

What each procedure changes

The procedure often called female sterilisation blocks or cuts the fallopian tubes, which connect the ovaries to the womb. This stops sperm meeting an egg. You may also hear the term tubal ligation. Vasectomy, sometimes called male sterilisation, prevents sperm from being ejaculated from the penis.

Tubal sterilisation does not change your hormone levels, and periods continue. If you previously used hormonal contraception that made bleeding lighter, stopping that contraception can change your periods. That is separate from the effect of the operation on the tubes.

Tubal surgery may involve keyhole surgery, called laparoscopy, or a mini-laparotomy using larger cuts in the tummy. Recovery can take longer after the larger-cut procedure. Ask which approach is planned and what help you may need afterwards.

Vasectomy is usually done with local anaesthetic. The NHS says there is no evidence of a long-term effect on sexual performance or enjoyment. Neither vasectomy nor tubal sterilisation protects against STIs; condoms can reduce that risk.

Deciding about permanence

These methods may suit you if you do not want children, or do not want any more. You do not have to have had children already. NHS guidance calls for counselling before female sterilisation, including an explanation of the options and risks.

You can discuss the possibility of changing your mind without having to defend your choice. The FDA says permanent surgery may not be right if you are uncertain about future children. Reversal needs another operation and may not work. The NHS also says vasectomy reversal does not always succeed and is not usually available on the NHS.

CDC recommends discussing long-acting reversible alternatives too. You can compare how each option fits your wishes, including how you feel about an operation intended to be irreversible. Take unresolved questions back to the clinician before agreeing to surgery.

How effective the methods are

The NHS describes female sterilisation as more than 99% effective. US CDC guidance gives 0.5 out of 100 tubal-surgery users becoming pregnant in the first year of typical use, and a vasectomy failure rate of 0.15 per 100 users in the first year of typical use. The sources report effectiveness in different ways.

Pregnancy can still happen after permanent contraception, including many years after tubal surgery. These methods are highly effective, but permanence does not guarantee protection against pregnancy. If pregnancy happens after tubal sterilisation, there is a higher chance that it is an ectopic pregnancy.

Waiting for confirmation after vasectomy

Continue another method until a doctor confirms the vasectomy has been successful. Confirmation involves semen analysis. The NHS describes this as usually taking around 12 weeks; CDC recommends semen analysis at 8–16 weeks. Follow your service’s appointment and sample instructions.

You still need confirmation, however much time has passed. Ask how to provide the sample, how results will reach you and who will confirm when you can rely on the procedure. The number of ejaculations cannot reliably tell you whether the semen test will confirm success.

Aftercare advice differs between countries

For female sterilisation, NHS guidance says usual contraception needs to continue temporarily after the operation, with exceptions depending on the existing method. CDC says laparoscopic and abdominal tubal surgery can be relied on immediately. Follow the surgical team’s instructions for your procedure and any prescribed contraception; do not apply another country’s advice to change the plan yourself.

Before discharge after tubal surgery, the team explains wound care and return to everyday activities. After vasectomy, some testicular pain and swelling are common during recovery. Long-term testicular pain is an uncommon complication worth discussing before the procedure.

When to contact the team

Call 999 now (UK) or 911 (US), or your local emergency number, for severe difficulty breathing or chest or upper-back pain after tubal surgery, or sudden severe abdominal pain with marked dizziness or fainting.

Contact your surgical team or NHS 111 urgently today (UK), or your surgeon or urgent care service (US and elsewhere), after tubal surgery for a high temperature, a swollen painful wound or wound leakage, a swollen painful leg, or abdominal pain with vomiting.

Get urgent medical advice now from a GP or NHS 111 (UK), or an urgent medical service (US and elsewhere), for lower abdominal pain, unusual vaginal bleeding or shoulder-tip pain if pregnancy is possible after tubal sterilisation, even without a positive test. Do not wait for a positive test.

Contact your surgical team, an urgent GP service or NHS 111 today in the UK, or your surgeon or urgent care service in the US and elsewhere, after vasectomy if pain or swelling suddenly worsens or is not improving after a few days. A high temperature, wound leakage or a growing scrotal lump also needs urgent advice.

For a discussion before deciding, book with a GP or sexual health clinic in the UK, or your healthcare provider in the US and elsewhere. Bring your questions about permanence and alternatives. Ask what recovery involves and how the team will confirm that the procedure has worked.
