Treatment Overview
About Vasectomy (male sterilisation)
A vasectomy is a minor, routine procedure designed to be a permanent form of contraception for men. It works by preventing sperm from reaching the semen that you ejaculate. During the procedure, the two small tubes (the vas deferens) that carry sperm from the testicles are cut and sealed. It is usually carried out under local anaesthesia (numbing injections).
Your specialist makes a tiny incision in the skin of the scrotum to reach the tubes. This is a highly effective form of contraception, with a fast recovery. You will still be able to ejaculate and enjoy the same sex drive and sensations—the only difference is that the fluid will no longer contain sperm.
Safety Information
Benefits, Risks & Side Effects
01
Benefits
A vasectomy is one of the most reliable forms of contraception in the world, with a success rate of over 99.9%.
Quick & Simple: The procedure usually takes just 15-30 minutes.
Fast Recovery: Most men are back to light daily activities within 2 days.
Partner Support: It removes the need for your partner to use hormonal birth control or for either of you to rely on barrier methods like condoms.
Permanent Solution: It is a one-time procedure that provides a lifetime of protection.
02
Risks
While a vasectomy is the most effective method of male sterilisation and follows best-practice standards, it is important to understand the potential risks.
🟡 Occasional (Between 1 in 10 and 1 in 50 patients)
Significant Swelling: A risk of significant bruising and scrotal swelling that is severe enough to require surgical drainage.
Infection: Developing epididymo-orchitis, which is an infection or inflammation of the testicle that may require treatment.
Hospital-Acquired Infection: A general risk (4–6%) of acquiring an infection such as MRSA during a hospital stay.
🔴 Rare (Between 1 in 50 and 1 in 250 patients)
Chronic Testicular Pain: Between 1% and 2% of patients (1 in 50 to 1 in 100) may develop troublesome chronic pain that is severe enough to affect day-to-day activities.
Early Failure: In approximately 1 in 250 cases, post-operative tests show persistent sperm, meaning the procedure was not immediately successful in achieving sterility.
Late Failure: A very rare risk (1 in 2,000) where the ends of the tubes re-join themselves long after initial negative sperm counts, potentially leading to a later pregnancy.
General Medical Issues: Rare complications related to anesthesia or the heart, such as blood clots or chest infections.
03
Side Effects
To help you prepare for your recovery, we use the following traffic light system to outline common after-effects. These are typically self-limiting and settle as your body heals.
🟢 Common (More than 1 in 10 patients)
Bruising and Swelling: Almost all patients experience mild bruising and scrotal swelling, which may include the seepage of clear yellow fluid from the wound after a few days.
Blood in Semen: It is very common to notice blood in your semen the first few times you ejaculate after the procedure.
Temporary Procedure Sensations: When the surgeon handles each tube during the operation, you may feel a moment of discomfort that can make you feel light-headed, sweaty, or slightly sick; this usually passes very quickly.
Stitch Irritation: Absorbable stitches are used to close the skin; these can feel slightly irritating but will typically disappear within two to three weeks.
Patient Journey
What to Expect
A step-by-step guide through your Vasectomy (male sterilisation) journey—from preparation and what happens during the procedure to recovery and aftercare.
01/ 03
Before Procedure
Your journey begins with a consultation to ensure you are comfortable with the permanent nature of the procedure.
You will have a pre-assessment to make sure that you are fit for any procedure.
You will need to sign your consent form and make sure that you understand the risks of the operation.
Fasting: As the procedure is usually done under local anaesthesia, fasting is not always necessary. If you are having a general anaesthetic (where you are asleep), you must not eat or drink for 6 hours beforehand.
02/ 03
During Procedure
The procedure is typically performed while you are awake using a local anaesthetic to numb the area, or under general anaesthetic. This will have been discussed with you in the clinic.
The specialist numbs the skin and the tubes.
As small incision is made in the skin of the scrotum
Each tube is gently lifted, the ends are sealed using ties or heat, and a small section may be removed.
One or two stitches may be used to close the skin.
03/ 03
After Procedure
Rest is your priority for the first 48 hours. Using an ice pack (or a bag of frozen peas wrapped in a towel) for 10 minutes at a time can help keep swelling down.
Crucial Rule: You are not sterile immediately. You must continue using another form of contraception until you provide a semen sample (usually 16 weeks later) that confirms no sperm are present, and your specialist has informed you that this is the situation.
Activity: Avoid heavy lifting, gym sessions, or cycling for 7 days.
Sex: You can resume sexual activity after about a week, as soon as you feel comfortable, but remember to keep using protection until your 'all-clear' test results arrive.

Frequently Asked Questions
Common questions about this treatment and what to expect.
3 questions
No. There will still be 'leftover' sperm in the tubes above the site where they were cut. It typically takes about 20 to 30 ejaculations over 12 to 16 weeks to clear these out. You **must** continue using another form of contraception until you have a semen analysis that proves your count is zero. Prematurely stopping contraception is the most common cause of 'failed' vasectomy pregnancies.

Absolutely not. A vasectomy only blocks the passage of sperm. It does not affect the production of testosterone (the hormone responsible for sex drive) or the blood flow required for erections. Your semen will look, smell, and feel the same as before; the only difference is that it will no longer contain microscopic sperm cells.

A vasectomy should be viewed as a permanent decision. While reversal surgery is possible, it is a complex 'microsurgical' operation that is rarely available on the NHS and often costs £5,000+. Success rates for reversal decrease significantly the longer it has been since the original vasectomy. If you have any doubts about wanting more children, it is better to wait.
