Are Vasectomies Safe?

Looking for a permanent method of contraception? Then a vasectomy might be for you! This surgical procedure, which involves blocking the vas deferens, prevents the sperm from passing into the semen and therefore prevents fertilisation. What are the advantages and drawbacks of this type of contraception? Read on to find out!

In the UK, vasectomies have been covered on the NHS since 1974. It is considered a permanent method of contraception, available to any adult male after a mandatory reflection period and a thorough medical consultation. This step aims to ensure that the decision is well thought out and freely consented to, without the involvement of external pressure.

There are two types of vasectomy:

  • Conventional vasectomy: An incision is made on both sides of the scrotum to cut the vas deferens.
  • No-scalpel vasectomy: The doctor makes small puncture holes in the scrotum to reach the vas deferens. This technique is less painful and less invasive than traditional vasectomy, and the risk of postoperative complications is minimal. It is also just as effective.

In any case, a vasectomy is a quick procedure that lasts between 15 and 20 minutes. The procedure can be performed at a hospital or a clinic, and the scrotum is numbed using a local anaesthetic. The patient is normally discharged the very same day, and recovery tends to be quick and simple.

What Are the Advantages and Drawbacks of a Vasectomy?

A vasectomy allows a man to take charge of their own contraception and to free their partners from restrictive contraceptive methods (birth control pills, IUD, etc.). This safe method of contraception allows couples to enjoy a fulfilling sex life, free from the fear of pregnancy.

As with any form of contraception, vasectomies come with certain benefits, but also some limitations that you should be aware of, before undergoing the procedure. You should weigh up the pros and cons with relation to your personal situation, your future plans and your relationship.

The advantages of a vasectomy

  • Peace of mind: You don't have to worry about your partner forgetting to take her pill or condom breakage. You’ll both feel freer! For some couples, vasectomies can even out the mental burden of contraception. The man taking charge of this part of intimacy can help to reinforce feelings of shared responsibility within a relationship.
  • Effectiveness: With a 99% success rate, vasectomy is the most effective method of contraception.
  • Low risk: The procedure is simple and does not require a general anaesthetic. Patients can return to their everyday life very quickly.
  • Covered by the NHS: Your vasectomy should be covered by the NHS. However, the wait list may be long.
Advantages
LOVE Team Tip
A vasectomy will not protect you against sexually transmitted diseases (STDs) or sexually transmitted infections (STIs). Keep using condoms if you’re having sex with an unfamiliar partner.

The drawbacks of a vasectomy

  • Post-operative pain: You may feel some moderate pain in the scrotum. This should disappear quickly with the right medication.
  • Delayed sexual activity: You should wait until you have fully recovered before having sex again.
  • Elimination of live sperm: Sperm should disappear within three months of the operation. You won’t be immediately infertile, and during this period you’ll need to use another method of contraception to prevent pregnancy. Follow-up tests (seminograms) are usually prescribed after the procedure to confirm the total absence of sperm in the semen. Until this result has been formally established, the vasectomy should not be considered fully effective.

Are Vasectomies Reversible?

Vasectomy is more or less irreversible depending on the country in which it is performed.

  • In the UK, a vasectomy cannot be easily reversed. Plus, while the operation itself is usually covered by the NHS, a reversal will not be.
  • In other countries (like Australia) : reversibility is possible because of different surgical techniques and legislation. However, reversibility is never completely guaranteed and it is important to remember that vasovasostomy is not 100% effective.

It’s important that you don’t go into the procedure using the idea of it being reversible as a back-up option. The chances of reversal being a success diminish the more time passes after the initial procedure, and results vary massively from one individual to another.

Before undergoing any surgery, you should discuss the issue carefully with your doctor and ask yourself whether you’re absolutely sure that you don’t want children. If you’re on the fence, don't take any risks and use another method of contraception.

How Will a Vasectomy Affect Your Sex Life?

The answer to this question is, of course, crucial for all men who are thinking about using this method of contraception.

  • Ejaculation and semen texture: You won't notice any difference before or after the procedure. Your ejaculations and the texture of your semen will be exactly the same. Your semen will simply not contain any sperm (which is the point of the operation!)
  • Erections and libido: Again, nothing will change! Your sexual desire will be completely unaffected by your vasectomy, as will your erectile capacity.
  • Feelings and pleasure: Your sexual pleasure will remain the same. You may even enjoy yourself more, as you’ll no longer have the hassle of contraception to think of.
How does vasectomy affect your life

The vasectomy will not affect your libido or your pleasure. It will have no negative effect on your sex life and will not prevent you from enjoying intense and satisfying sexual activity.

Vasectomies may be a great contraceptive option for some men and/or couples, provided that it’s something that’s been carefully decided upon beforehand. An open discussion with your health professional is crucial if you want to ensure that you make an informed choice that is aligned with your desires, values and future.
