Vasectomy

A male vasectomy, also called male sterilisation or ‘the snip’, is a simple procedure that blocks or seals the tubes carrying sperm from the testicles. This prevents sperm from being present in semen, providing a permanent form of contraception.

The procedure does not affect your hormones, sex drive, ability to get an erection or sexual pleasure. It's a reliable, long-term solution to prevent pregnancy, giving peace of mind for men who are certain they don’t want (more) children.

Why you might choose male sterilisation 

Deciding to have a vasectomy is a very personal choice, and it can be influenced by your life circumstances and family plans.

You might consider a vasectomy if you’ve already fathered children and feel your family is complete, or if you have decided you don’t want to become a father. Some people choose the procedure because they and their partner want a reliable, long-term method of contraception that removes the risk of unintended pregnancy.

For many men, a vasectomy brings peace of mind and a sense of control over their future. It’s a highly effective procedure, with only around 1 in 2,000 men who have a vasectomy impregnating a partner.

Is a vasectomy right for you?

A vasectomy is a permanent form of contraception, so it’s important to be confident it fits with your future plans. It’s not suitable if you think you might want children later or are unsure about your decision.

While vasectomy reversal surgery does exist, its success isn’t guaranteed and the procedure is more complex than a vasectomy itself. For this reason, it’s best to view a vasectomy as a permanent choice rather than something that can reliably be undone later.

At Spire Healthcare, our experienced urologists take the time to understand your personal circumstances. During your consultation, they’ll talk you through how the procedure works, what you can expect before and after surgery, and the potential risks and limitations — including what reversal can realistically achieve. This helps you make a decision that feels safe, informed and right for you.

Does getting a vasectomy impact sex life?

It’s natural to wonder how a vasectomy might change your sex life. It’s reassuring to know that, for most men, nothing about intimacy or sexual pleasure is affected.

A vasectomy doesn’t change your hormones, sex drive or ability to get and maintain an erection. You’ll still ejaculate as normal and orgasms will feel the same. Many people are surprised by how little difference they notice once they’ve recovered.

You will need to continue using another form of contraception until a follow-up semen test confirms that no sperm are present. This is an important step to make sure the procedure has been fully effective.

While a vasectomy prevents pregnancy, it doesn’t protect against sexually transmitted infections. If you or your partner could be at risk, using condoms is the best way to keep both of you safe.

Overall, most men report feeling more relaxed and confident during sex once they no longer need to worry about unintended pregnancy, helping intimacy feel more natural and enjoyable.

A vasectomy is a short, carefully performed procedure, and our team is here to help you feel at ease from the moment you arrive.

You’ll be given a local anaesthetic so the area is completely numb. Although you’ll remain awake, most people only feel a gentle pressure rather than any discomfort. The procedure lasts around 20 minutes.

During the procedure, your surgeon makes a very small opening on each side of the scrotum to reach the tubes (vas deferens) that transport sperm. A small segment of each tube is removed, and the ends are then sealed or tied to stop sperm from entering the semen.

Before the procedure

Before your appointment, you’ll meet with your consultant to talk through the procedure, ask questions, and discuss anything that may be on your mind. This is also when your surgeon will review your medical history, current medications, and any relevant health conditions to ensure the procedure is tailored to you.

We’ll give you clear instructions on how to get ready — from simple lifestyle steps to practical instructions for the day of surgery — to help everything run smoothly and support your recovery.

Preparing in advance

In the weeks leading up to your vasectomy, you may be advised to:

• Make healthy lifestyle choices, such as stopping smoking, reducing alcohol and maintaining a healthy weight
• Keep your blood sugar levels well controlled if you have diabetes
• Share your full medication list so your doctor can confirm if anything needs to be adjusted
• Support your general wellbeing with regular exercise and good hydration

Food and drink

Most vasectomies are carried out under local anaesthetic, which means you generally won’t need to fast. If your surgeon advises otherwise — for example, if a general anaesthetic is planned — they’ll give you clear, personalised instructions on when to stop eating and drinking.

Preparing on the day

On the day of the procedure, we recommend:

• Arriving in plenty of time so you can relax before your appointment
• Taking a bath or shower, ensuring the scrotal area is clean
• Wearing comfortable, supportive underwear

When you come in, you’ll meet the team looking after you and have the chance to ask questions.

Who will be involved?

Your care is led by a consultant urologist with specialist experience in vasectomies. They’re supported by an expert team of nurses and, where needed, an anaesthetist.

All of our doctors are highly trained, GMC-registered, and experienced in delivering safe, patient-centred care.

From your first consultation to your final check-up, our team will be there to reassure you, explain what to expect, and provide personalised advice every step of the way.

The procedure

How long does the procedure take?

A vasectomy usually takes around 20 minutes, though this can vary slightly depending on your anatomy and the surgical technique used.

Anaesthetic choices

Most people have a local anaesthetic, so you’ll be awake but the area will be completely numb and pain-free. If your surgeon recommends a general anaesthetic, this will be discussed with you in advance.

Hair removal

Hair around the surgical site may need to be removed so the surgeon can access the area. This is usually done in theatre with electric clippers, though occasionally a depilatory cream may be used the night before.

Clothing

You’ll wear a gown and disposable underwear so the surgical team can access the site and attach monitors if needed.

Pain during and after surgery

With a local anaesthetic, you shouldn’t feel any pain during the procedure, just a sense of pressure or gentle tugging. Afterwards, it’s normal to experience some mild discomfort, swelling or bruising. Your care team will offer pain relief and advice on how to stay comfortable at home.

What happens straight after surgery

Once the procedure is complete, you’ll rest for a short time while our team checks that you are feeling well and comfortable. Most people are ready to go home soon after.

Because you may feel light-headed or sore, it’s important to have someone with you to take you home. This helps ensure you get back safely and can focus on resting for the remainder of the day.

Most men recover quickly after a vasectomy. Your scrotum may feel sore for 1–3 weeks, but most men can return to light, day-to-day activities in 2–3 days.

Short-term side effects of a vasectomy

After a vasectomy, mild swelling, bruising, tenderness, or slight redness around the cuts is normal and usually settles in a few days. You may also notice blood in your semen during the first few ejaculations.

Serious complications are rare, but contact your healthcare team if you notice increasing pain, heavy swelling, bleeding, or signs of infection.

First 24 hours recovery

After your vasectomy, you may feel some pain as the anaesthetic wears off. You’ll usually be able to go home the same day and can take paracetamol to ease the pain.

During the first 24 hours, it’s important to take things slowly:

• Avoid driving, using tools or machinery, or anything that requires full alertness
• Hold off on drinking alcohol or making big decisions until you feel back to normal
• Make sure someone can take you home and stay with you, if needed

Managing your recovery at home 

After resting for the first 24 hours, it’s important to keep moving gently to support healing and reduce the risk of complications. Some discomfort, swelling, or bruising in the testicles is normal for a few days, and over-the-counter painkillers can help.

Applying a cold pack and wearing supportive underwear can also ease swelling and improve comfort as you recover. Follow any instructions from your healthcare team to ensure a smooth and safe recovery.

Wound care

The small cuts are usually covered with a light dressing, which can be removed or will fall away in a day or two. Keep the area clean and dry, wash gently, pat dry, and wear supportive underwear to protect the scrotum and aid healing.

Pain relief 

Over-the-counter painkillers, such as paracetamol, are usually sufficient. Follow the recommended dose and speak to your doctor if you need stronger medication.

Smoking

Avoid smoking as it can delay healing.

Driving

Only resume driving once you feel comfortable and are no longer taking strong painkillers that could affect your reaction times.

Time off work

Most people take 1–2 days off, depending on the nature of their job. Those with physically demanding roles may need a longer break.

Resuming normal activities

Most individuals feel well enough to return to light, day-to-day activities in a couple of days. Work involving physical effort, sport, or heavy lifting should generally be avoided for about a week to allow the area to heal fully. Gentle walking is encouraged to aid recovery and circulation.

Resuming sexual activity

You can usually resume sexual activity about a week after the procedure, once any discomfort has eased. It’s important to continue using another form of contraception until your follow-up semen test confirms that no sperm are present, which is usually 8–12 weeks after surgery. This is because sperm may remain in the tubes for weeks or months after the procedure. It is estimated that around 20 ejaculations are needed to clear all the sperm and confirm sterility.

Although complications after a vasectomy are uncommon, you may experience swelling, bruising, or a lumpy feeling around the wound that lasts for weeks. Mild aches or twinges may continue for up to 6 months.

Infection is rare but can be treated with antibiotics. Contact your healthcare team promptly if you notice:

• Bleeding or discharge around the cuts
• Chest symptoms such as cough, shortness of breath, or pain
• Difficulty passing urine
• High fever, chills or increasing pain
• Redness and/or swelling
• Increasing pain
• Unexplained calf swelling

The only other reliable form of contraception for men is using condoms. Condoms not only prevent pregnancy but also protect against sexually transmitted infections (STIs).

Vasectomy reversal

A vasectomy can sometimes be reversed through a surgical procedure. However, success is not guaranteed, and the likelihood of restoring fertility varies depending on your circumstances and how long ago you had your vasectomy.
