The tubes that carry sperm from a man's testicles to the penis are cut, blocked or sealed with heat. There are two types of vasectomy procedure:
The skin of your scrotum is numbed with local anaesthetic. The doctor makes two small cuts, about 1cm 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.
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.
