How does a no-scalpel vasectomy work?

Vasectomy is a simple surgical procedure where a surgeon seals the sperm-carrying tubes (called vas deferens) to prevent sperm entering the fluid a man ejaculates.

It takes about 15 minutes, and is one of the most effective methods of contraception that exists – the failure rate is about 1 man in 2000. After a vasectomy the testicles will continue to produce sperm as normal, but the sperm cannot enter the tubes and is simply absorbed into the body. You will still form an ejaculate after a vasectomy, but it will not contain sperm.

There are two methods of vasectomy: no-scalpel (cautery) and cut & tie. Marie Stopes UK provides the no-scalpel (cautery) method only as it offers faster recovery, and still has the same efficacy as cut & tie. A no-scalpel (cautery) vasectomy is performed as follows:

  • A fast acting local anaesthetic is given before the procedure, which numbs the area.
  • A small incision is then made in the scrotum to locate and heat seal the vas deferens (sperm carrying tubes). The incision is very small and no scalpel or stitches are needed, except in very rare cases.
  • The small incision is then protected via a dressing and the procedure is complete.
