How Does A Vasectomy Work?

Vasectomy is the most effective method of male sterilisation. It involves the removal of a small section of the tube (vas deferens) that carries the sperm cells from the testicle such that the seminal fluid will no longer contain sperm cells. Most of the ejaculatory volume comes from the prostate, which won’t be affected by vasectomy, it simply won’t contain sperm cells. 

The procedure is usually relatively quick (15-20 minutes) and is most often performed under local anaesthetic. Sometimes, however, a general anaesthetic may be recommended by the surgeon or requested by the patient.

What happens after the procedure?

Naturally, there will be some swelling and soreness, with feelings of discomfort often lasting a few days whilst the healing process takes place. It’s also important to follow the doctor’s instructions and limit activities, such as sports and any sexual activity for at least a week. In some cases the surgeon may ask that you wear a scrotal support for a short time after surgery.

You may also need to apply an ice pack to the scrotum to reduce any swelling. If you experience increasing pain or continued swelling, you should seek medical attention as this could be a sign the incision has become infected.

How long after the procedure will the treatment become effective?

It’s advised that at least 12 weeks must pass, and you have over 20 ejaculations, before you will cease to pass sperm. Up until this point, if you wish to continue sexual activity, you will need to use other forms of contraception. You will still be able to ejaculate, though this will just be seminal fluid. 

You will also be required to attend a post-op semen test to make sure that no sperm is present in your semen. You will be asked to bring in a sample 12 weeks after the procedure to be sent to the lab for analysis. This is included in the cost of the procedure and is the only way to be sure the procedure has been a success.

Vasectomy FAQs

Before having the vasectomy treatment, it’s important to learn as much about the procedure as possible. To help you understand vasectomies in more depth, here are some of the most frequently asked questions surrounding the treatment.


How long will a vasectomy last?

The procedure can take anywhere from 10 to 30 minutes, with the effects of the treatment being permanent. You won’t be sterile immediately after the surgery, though the end result will last for the rest of your life.

Will a vasectomy affect my sex drive?

A vasectomy won’t affect your sex drive as it won’t change the way your body produces testosterone, so your testicles will continue to work in exactly the same way. Nothing about the sensation of sex or your ability to get an erection will be changed by a vasectomy.

Can a vasectomy increase the risk of cancer?

Both men who have had a vasectomy and those who haven’t are susceptible to prostate cancer. There is no evidence to suggest that a vasectomy can increase the risk of cancer, and as a vasectomy doesn’t alter your testicles or sperm production, it is unlikely this would be the case.

Will a vasectomy affect my mental health?

Nothing about the procedure will affect how your brain works in a chemical sense. However, it is normal to feel anxious about the procedure if you’re not completely sure it’s the right decision. If you’re confident that a vasectomy is for you, it is likely you’ll feel relief once the treatment is complete.

Is a vasectomy painful?

Before the surgery is carried out, you will be given either local or general anaesthetic beforehand to ensure you experience no pain. If you’re having the surgery under local anaesthetic, it is common to experience discomfort, but this shouldn’t be painful.

Once the anaesthetic has worn off, usually around 4-6 hours after the operation, you may experience some pain during the healing process.

How do I clean after a vasectomy?

To aid the healing process, it is important that you avoid showering for at least 24 hours after the surgery, as the incision area needs to be kept dry. Once initial healing has taken place, you may carefully clean the area, avoiding any substantial pressure to prevent the wound from reopening.

Will I still produce sperm after a vasectomy?

Having a vasectomy doesn’t stop your body from producing sperm, it simply prevents it from being expelled from the body during ejaculation. Natural production of sperm will still take place in the testicles, however, it is absorbed by the body as it cannot be passed through the vas deferens.
