10 Frequently Asked Questions About Having a Vasectomy

Vasectomy  •  2 July 2022  • 4 min read



A Vasectomy is a popular method of family planning, a contraceptive method that is suitable for people who are sure they don’t want any, or any more, children. It’s safe, effective and offers a permanent solution to your contraceptive needs. The procedure takes about 15 minutes, and is one of the most effective methods of contraception that exists.

In this blog, we have collected 10 of the most commonly asked questions about having a vasectomy.

1. How does a vasectomy work?

Our expert surgeons use the non-scalpel technique. It is effective, should cause very little bleeding, stitches are rarely needed, and there is a low complication rate.

During the procedure, which takes around 15 minutes, a surgeon will seal the sperm-carrying tubes (vas deferens) to prevent sperm entering the fluid which a man ejaculates.

2. Does a vasectomy work straight away?

No. There will be some sperm left in your tubes after your procedure, so you will need to use another method of contraception until we have confirmed the success of your vasectomy. We will test your semen no earlier than 16 weeks after your procedure. After we have received your sample, we will write to inform you if your vasectomy has been successful and that you can stop using contraception. In some cases, this can take several tests.

3. Is a vasectomy 100% effective?

A vasectomy is a very effective way to prevent a pregnancy. We do not use scalpels as part of the vasectomy procedure. This is called the non-scalpel technique. The reason why we offer the non-scalpel procedure is because it is thought to be less painful. It is also less likely to cause complications. A non-scalpel vasectomy should cause very little bleeding, and stitches are rarely needed.

4. Will I still be able to ejaculate?

Yes. Vasectomy does not affect orgasm or the appearance of your semen.

5. Will a vasectomy affect my sex life?

Having a vasectomy will not affect your sex drive. After a vasectomy, the testicles will still produce the hormone testosterone, which is the male sex hormone. Many couples say that they enjoy sex more after a vasectomy. This is because they can choose to have sex more spontaneously, without worrying about an unintended pregnancy.

6. When can I have sex after my vasectomy?

You can resume sexual activity whenever you feel comfortable. We advise you refrain from sexual intercourse for 48-72 hours after the procedure. Make sure to use contraception until we confirm in writing that your vasectomy has been successful.

7. How long will it take to recover after having a vasectomy?

You should take a few days to relax and rest up after the procedure. If you have a job that involves physical strain then we advise that you take a couple of weeks off. Avoid heavy lifting or contact sports. We advise that you recline as much as possible during your recovery.

8. Can I play sports after my vasectomy?

Avoid sports and physical exercise for at least 2 weeks following the procedure. This includes swimming and golf. Heavy physical exercise and contact sports should be avoided for 4 weeks. Examples include rugby, football, squash, cycling, skiing and going to the gym.

You can judge your recovery by how quickly your wound is healing and how fast any swelling or pain goes away.

9. How will I know if my vasectomy has been successful?

To make sure that your vasectomy procedure has been successful, we need to test your semen in a laboratory. After your vasectomy procedure, you will be given a semen-testing kit, which comes with instructions and a return envelope. After testing the sample, we will write to you to confirm that your vasectomy has been successful. Until you receive confirmation, you should use another form of contraception to prevent pregnancy.

10. Can I reverse my vasectomy if I change my mind?

Vasectomy reversal is possible, but success is not guaranteed and depends largely on how long ago it was done. It is much better to consider vasectomy a permanent procedure.
