The vas deferens is the tube which runs from each testicle to the penis, hence the name vasectomy

As there is a vas on each side, both will need to be cut

The “No-Scalpel” technique uses a diathermy instrument (electrosurgery) and is the preferred method due to its low rate of infection and bruising

The procedure is performed by first examining the area to make sure the procedure can be done

An injection of a local anaesthetic is given to the middle of the scrotum and the vas using a very fine needle

The vas is fixed using a special pair of ring forceps, and a small split is made in the skin (less than 1cm) and the vas is hooked out and approximately 2cm is destroyed using the diathermy and the vas is divided

This is then repeated on the other side through the same split

In most cases there is very little bleeding and no stitches are required; however 1 in 100 cases may require a stitch

Having a vasectomy has no effect on a man’s sex drive as this depends on Testosterone (the male sex hormone) which is produced by the testes and enters the blood stream directly. 

Ejaculation should not be affected as semen, which accounts for most of the ejaculate liquid, is produced by the seminal vesicles.
