What is a vasectomy?

A diagram showing a side-on view of the penis and testicles and the tube that carries sperm from the testicles (sperm duct).
  • Vasectomy, also called male sterilisation, is a permanent method of contraception.
  • It’s a procedure that stops sperm being ejaculated from the penis during sex.
  • It’s usually carried out under local anaesthetic and takes around 30 minutes. It’s common to feel some pain for 1 to 2 weeks afterwards.
  • Vasectomy is available on the NHS. There is usually a waiting list.
  • It may be possible to reverse a vasectomy, but this does not always work. Reversal is not usually available on the NHS.
Information:

A vasectomy does not stop you getting and passing on sexually transmitted infections (STIs). Use a condom every time you have sex to protect you and your partner against STIs, including HIV.
