Local anaesthetic is injected into the skin of the scrotum with minimal discomfort. Once the local starts working you should feel no pain. Afterwards you may feel some discomfort for a number of days and you may need to take some paracetamol. Discomfort is significantly less with the no-scalpel method because there is less injury to tissue.

Usually the procedure takes no longer than 30 to 40 minutes, however you can expect to be in the surgery for approximately 60 minutes.

No. However it is desirable that you talk it over with your GP who is familiar with your medical history. If you wish to see us directly we may ask your permission to contact your doctor to ensure that there is no medical reason that would make it unsafe or unwise to have a vasectomy.

It is estimated that after a vasectomy there is less than a 1 in 2000 chance of pregnancy.

Most men feel sore and tender for a few days after the operation, and will usually experience some bruising and swelling on or around their scrotum.

However, in some cases, a vasectomy can cause more serious problems, some of which are outlined below.

Haematoma – a haematoma is when blood collects and clots in the tissue surrounding a broken blood vessel. Following a vasectomy, you may develop a haematoma inside your scrotum.

Haematomas are mostly small (pea-sized), but can occasionally be large (filling the scrotum) and, rarely, they can be very large. This can cause your scrotum to become very swollen and painful. In severe cases, you may need further surgery to treat the blood clot.

Sperm granulomas – when the tubes that carry sperm from your testicles are cut, sperm can sometimes leak from them. In rare cases, sperm can collect in the surrounding tissue, forming hard lumps that are known as sperm granulomas.

Your groin or scrotum may become painful and swollen either immediately or a few months after the procedure. The lumps are not usually painful and can often be treated using anti-inflammatory medication, which your GP will prescribe. If the granulomas are particularly large or painful, they may have to be surgically removed.

Infection – after a vasectomy, you may be at risk of developing an infection as a result of bacteria entering through the cuts made in your scrotum. Therefore, after the operation, it is important to keep your genital area clean and dry to keep the risk of infection as low as you can.

Long-term testicle pain – some men get pain in one or both of their testicles after a vasectomy. It can happen immediately, a few months or a few years after the operation. It may be occasional or quite frequent, and vary from a constant dull ache to episodes of sharp, intense pain. For most men, however, any pain is quite mild and they do not need further help for it.

Long-term testicular pain affects less than one in 100 men after vasectomy and is associated with older methods of vasectomy. The pain can be the result of a pinched nerve or scarring that occurred during the operation. Medication usually helps but if pain persists, you may be advised to undergo further surgery to repair the injury and to help minimise further pain.

Testicles feeling full – after a vasectomy, some men may develop the sensation that their testicles are “fuller” than normal. This is usually caused by the epididymis becoming filled with stored sperm. The epididymis is the long, coiled tube that rests on the back of each testicle. It helps to transport and store sperm.

Any such feelings should pass naturally within a few weeks. However, speak to your GP if you are still experiencing fullness after this time.

Fertility – in a very small number of vasectomy cases, the vas deferens reconnects over a period of time. This means that the vasectomy will no longer be an effective form of contraception. However, it is rare for this to happen.

Yes, it is safe, but as with all surgery complications such as bruising, bleeding, infection, and scarring are possible. Serious complications are very rare. Less than 1 in 100 cases has even a minor problem.

You must be sure you do not want to father a child under any circumstances. It is important you talk to your partner and make this decision together.

It may not be right for you if you are very young, your relationship is not stable, you are under a lot of stress, or you are having the vasectomy just to please your partner.
