How is a vasectomy done?

A vasectomy, also known as male sterilization, is a quick and virtually painless surgical procedure. The tubes that carry sperm from the testicles to the penis are sealed preventing pregnancy. The procedure is effective and permanent and you will be able to return home the same day.

In the male genitalia, there are two tubes, called vas deferens which carry sperm that to the penis. A vasectomy disrupts each vas deferens preventing sperm entering and activating semen.

So, what happen to the sperm? Sperm cells stay in your testicles and are absorbed by your body. After 3 months of vasectomy, your semen won’t contain any sperm, so it can’t cause pregnancy. But this does not mean that you are not going to have semen. You can still ejaculate semen without the sperm.

Vasectomies at the Cadogan Clinic are carried out as a day case surgery under local anesthetic. This means that only your scrotum will be numbed, and you will be awake for the procedure. You will not feel any pain, although it may feel slightly uncomfortable.

Occasionally patients prefer a general anaesthetic, but it is still a day case procedure. At the Cadogan Clinic we use TIVA (Total IntraVenous Anaesthesia) which is light and allows you to go home early.
