Vasectomy or 'male sterilisation' is a simple and reliable method of contraception. It is usually considered permanent, although in some cases the procedure can be reversed - for example, if the male decides to have children later on in life.

How does a vasectomy work?

Sperm is prevented from reaching the semen ejaculated from a man's penis during sex. It is a quick and relatively painless surgical procedure, usually carried out under local anaesthetic. In most cases, you will be able to return home the same day as your procedure.

A vasectomy has no effect on sex drive or ability to enjoy sex. You will still have erections and ejaculate normally. The only difference is that your semen will not contain sperm.

How long will I have to wait?

In most parts of the UK, a vasectomy is available free of charge under the NHS. However, waiting lists can be several months, depending on where you live.

Speak to your GP about availability of vasectomies in your area. As waiting lists for vasectomies can be long, some men choose to pay to have the procedure carried out privately.

What are the benefits?

A vasectomy may be appropriate when a couple do not want more children, or have decided not to have any at all. It may be chosen as a simpler, safer and more reliable alternative to female sterilisation.

A vasectomy is normally permanent, so once it has been carried out successfully and semen tests have shown there is no sperm present, long-term partners may not need to use other forms of contraception.

However, a vasectomy does not protect against HIV infection or any other sexually transmitted infection, so you should continue to protect yourself by using condoms with any new partner.

Will it affect my sex drive?

After a successful vasectomy, your testicles will continue to produce the male hormone (testosterone) just as they did before the procedure. Your sex drive, sensation and ability to have an erection won’t be affected. The only difference is that there will be no sperm in your semen. Your body still produces sperm, but they are reabsorbed without harm.
