Vasectomy

SUMMARY

A vasectomy is a minor surgical procedure where a doctor cuts, blocks, or seals the tubes that carry sperm from the testicles into the semen.

How it works

Prevents sperm from mixing with semen, so sperm can’t leave the penis or reach an egg.
Semen is still produced, but it won’t contain sperm.

More than 99% effective.
It can take up to 3 months after the procedure for all sperm to clear from the tubes, so another form of contraception is needed until a test confirms it’s working.

You’ll need a semen test about 3 months after the procedure to confirm it’s worked.
Does not protect against STIs, so condoms may still be needed.
Some short-term discomfort, swelling, or bruising can happen after the procedure.

No, a vasectomy cannot be tampered with once it has been done.
