Vasectomy (male sterilisation)

These are very rare.

• There is a risk that sterilisation will not work.
• The tubes that carry the sperm can re-join after sterilisation. This can happen immediately or some years after the operation has been carried out.
• A haematoma can form. A haematoma is when blood collects and clots in the tissue surrounding a broken blood vessel. Haematomas are mostly small (pea-sized) but can occasionally be large. In severe cases, you may need further surgery to treat the blood clot.
• Sperm granulomas, when leaked sperm from the cuts can collect in the surrounding tissue, forming hard lumps that are known as sperm granulomas. 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.
• 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. Any such feelings should pass naturally within a few weeks, however, speak to your GP if you are still experiencing a dull ache 3 weeks after the procedure.

Yes, vasectomy is available on the NHS.

Wearing close-fitting clean underwear, such as Y-fronts, during the day and at night will help to support your scrotum and will also help ease any discomfort or swelling.

Most men will be fit to return to work 1 or 2 days after their vasectomy, but you should avoid sport and heavy lifting for at least 1 week after the operation.

Your GP or local sexual health clinic.

It is a big decision to end the part of your life where you could father a child. If you feel anxious or uncomfortable about the procedure, or if you think you would suffer mentally from being infertile, then it is not the best type of contraception for you.

You can discuss alternatives with your GP or with a professional at a contraception clinic (sometimes called a family planning clinic).

Vasectomy does not affect your hormone levels or sex drive.

Although prostate cancer and testicular cancer can occur in men who have had a vasectomy, research suggests that vasectomy does not increase your risk of cancer.

The surgeon will discuss the risks and benefits of both methods with you.

The tubes that carry sperm from a man's testicles to the penis are cut, blocked or sealed with heat. There are 2 types of vasectomy procedure:

Conventional

The skin of your scrotum is numbed with local anaesthetic. The doctor makes 2 small cuts, about 1 cm long, on each side of your scrotum to access the tubes that carry sperm from your testicles. Each tube is cut, and a small section removed. The ends of the tubes are then closed, either by tying them or sealing them using heat.

The incisions are stitched, usually using dissolvable stitches, which will disappear naturally within about a week.

No-scalpel vasectomy

Usually carried out under local anaesthetic. The doctor will feel for the vas deferens tubes (the tubes that carry sperm) underneath the skin of your scrotum and then hold them in place using a small clamp.

A special instrument is then used to make a tiny puncture hole in the skin of the scrotum. A small pair of forceps is used to open up the hole, allowing the surgeon to access the vas deferens without needing to cut the skin with a scalpel. The tubes are then closed in the same way as in a conventional vasectomy, either by being tied or sealed.

During a no-scalpel vasectomy, there will be little bleeding and no stitches. The procedure is also thought to be less painful and less likely to cause complications than a conventional vasectomy.

It is considered permanent. It can be reversed but is not always successful and is not usually available on the NHS.

After vasectomy it will take up to 20 ejaculations to clear the sperm from the tubes and during this time there is still a risk of pregnancy. At least 8 weeks after the procedure you will need to produce a semen sample which will be checked for sperm. You will need to use another method of contraception until you have 2 clear semen tests.
