Vasectomy: The Complete Guide to Male Sterilisation
A definitive, safe, and minimally invasive form of permanent contraception. Below, I explain what vasectomy involves, what to expect, and how I care for you throughout.
Quick Overview
What You Need to Know
If You Are Looking For
Definitive family planning — vasectomy is the most effective long-term contraceptive option for men who are certain their family is complete.
The Procedure
I use a modern no-scalpel access approach. This reduces tissue trauma, minimises bleeding and speeds up recovery. In around 70% of cases, I can perform the procedure through a single small access point.
What Is a Vasectomy?
A vasectomy is a straightforward surgical procedure that provides permanent contraception. It works by blocking the vas deferens — the tubes that carry sperm from your testicles — so sperm can no longer be released during ejaculation.
Vasectomy does not affect testosterone, erections, orgasm, or sexual sensation — it does not affect testosterone production, erections, orgasm, or sexual sensation. Your testicles keep producing testosterone normally. You'll still ejaculate; the only difference is that your semen won't contain sperm.
Understanding the Anatomy
The vas deferens are two tubes, each about 30cm long, that transport sperm from the testicles where they're produced to join the rest of the seminal fluid.
The reproductive anatomy involves several key structures:
The Testicles (Testes): These produce both sperm and testosterone. Sperm production continues after vasectomy, but the sperm are simply reabsorbed by your body – a natural process that happens safely and without any adverse effects.
The Epididymis: A coiled tube behind each testicle where sperm mature and are stored. This structure remains intact during vasectomy.
The Vas Deferens: These are the tubes I block during vasectomy. Each vas deferens runs from the epididymis up through the inguinal canal, eventually joining with the seminal vesicles to form the ejaculatory ducts.
The Seminal Vesicles and Prostate: These glands produce the fluid that makes up most of your ejaculate. They continue functioning normally after vasectomy, which is why you'll notice no difference in ejaculation volume – sperm account for only about 2-5% of ejaculate volume.
Important to Know: During vasectomy, I make a tiny opening in the scrotum to access each vas deferens, cut a small section, and seal the ends. This creates a permanent blockage whilst leaving all other structures completely intact. The no-scalpel access technique I use means this is done through an opening smaller than a traditional surgical incision, resulting in less discomfort and faster healing.
Vasectomy suits men who are certain they don't want to father children in the future. During our consultation, I'll explore your circumstances, relationships, and long-term family planning goals to make sure it's the right decision for you.
I won't proceed if I feel you're being pressured. This needs to be your decision.
Critical Consideration: Permanence
Whilst vasectomy reversal is technically possible, success rates vary considerably and reversal is a more complex procedure with no guarantee of restoring fertility. I always counsel patients to approach vasectomy as a permanent decision. If there's any uncertainty about future fertility desires, I'll discuss alternative contraceptive options that offer more flexibility.
Who Is Vasectomy Suitable For?
Vasectomy is appropriate for men who:
Are completely certain they don't want to father children in the future
Have reached this decision independently, without pressure or coercion
Understand the procedure is permanent
Are in good general health
Who May Not Be Suitable?
Vasectomy may not be appropriate if you:
Have any uncertainty about future fertility desires
Are experiencing current scrotal infection or inflammation
Have significant bleeding disorders or are taking anticoagulation medication (we assess these on a case-by-case basis)
Are feeling pressured or coerced into the decision
Have significant untreated anxiety about the procedure
If any of these apply, raise them during your consultation. We'll explore whether vasectomy is right for you, or whether alternative options are a better fit.

Quick Self-Assessment: Is Vasectomy Right for Me?
Answer honestly to help guide your thinking. This is not medical advice – we'll discuss your individual circumstances during consultation.
Who Typically Chooses Vasectomy?
Patient Profiles
Completed Families
Men who have children and are confident their family is complete. This represents the majority of patients seeking vasectomy.
Shared Responsibility
Partners who want to share contraceptive responsibility after years of their partner managing contraception, or when female contraception causes unwanted side effects.
Personal Choice
Men who have chosen not to have children and want reliable, permanent contraception that allows them to live life on their terms.
Medical Considerations
Men with genetic conditions or health concerns where pregnancy would pose risks, or who have partners for whom pregnancy would be medically inadvisable.
Not sure if vasectomy is right for you? Let's talk it through.
A consultation with Mr Ollandini is a no-pressure conversation. We'll explore your circumstances, answer every question, and help you make the right decision for you.
The Procedure: What Happens During Your Vasectomy
I perform vasectomies using the no-scalpel access technique under local anaesthetic. The procedure takes around 20 minutes, and you go home the same day.
Step-by-Step Process
Your Clinical Pathway
1. Initial Consultation
We discuss your circumstances, medical history, and expectations. I explain the procedure in detail and answer all your questions. You will have time to consider your decision — there is no pressure to proceed immediately.
2. Preparation
On procedure day, you will be asked to shower and wear comfortable, supportive underwear. The scrotal area is cleaned and prepared. Local anaesthetic is administered — you will feel a slight sting, then numbness sets in within minutes.
3. The No-Scalpel Access Technique
I locate each vas deferens through the skin and make a tiny opening of about 2–3mm using a special instrument. In many cases I can perform the entire procedure through a single small access point. Each vas is lifted, cut, and sealed. The no-scalpel approach means less trauma, minimal bleeding, and faster healing than traditional incision techniques.
4. Closure & Aftercare
The tiny opening often requires no stitches — it heals naturally. I will provide you with detailed written aftercare instructions and arrange your follow-up semen analysis. You will rest briefly before going home.
What You'll Experience During the Procedure
I believe in complete transparency about what you'll experience, so here's an honest account of the procedure from a patient's perspective:
Sensations During the Procedure
The anaesthetic injection feels like a small pinprick followed by a brief stinging sensation. This lasts only a few seconds, and within 2-3 minutes, the area becomes completely numb.
During the procedure itself, you won't feel pain due to the local anaesthetic. However, you may experience a pulling or tugging sensation as I locate and manipulate the vas deferens. Some men describe a brief feeling similar to being "flicked" in the testicle – this is normal and temporary. If you feel any sharp pain, tell me immediately so I can administer more local anaesthetic.
Anxiety management is important. Many patients feel understandably nervous, which is completely normal. I talk you through each step, and you're welcome to bring headphones to listen to music if that helps you relax.
The Environment
The procedure room is private, clean, and maintained at a comfortable temperature. You'll be lying on a procedure table with proper draping to maintain your dignity. I maintain a calm, professional atmosphere focused entirely on your comfort and safety.
My Commitment to You: I perform vasectomies regularly, and this experience means I can work efficiently whilst remaining attentive to your comfort. If at any point you need me to pause, slow down, or provide more anaesthetic, simply tell me. Your wellbeing is my priority throughout.
Why I Choose the No-Scalpel Access Technique
"No-scalpel" refers to how I access the vas (tiny puncture rather than an incision). The evidence shows this approach is associated with:
Less bleeding and bruising:
Tissue is gently spread rather than cut
Lower infection rates:
Smaller wound means reduced infection risk
Less post-operative pain:
Minimal tissue trauma
Faster recovery:
Patients typically return to activities sooner
Often no stitches required:
The tiny opening usually heals naturally
Overall effectiveness depends on the occlusion technique (how I seal the vas) and correct follow-up semen testing, which I'll arrange for you.

The procedure takes around 20 minutes under local anaesthetic. You'll go home the same day. Book your consultation to get started.
Recovery and Aftercare
Recovery is generally straightforward, though everyone heals at their own pace. Here's what to expect.
Recovery Timeline
First 48 Hours
Rest, ice packs, and supportive underwear. Mild discomfort is normal and well managed with paracetamol or ibuprofen. Avoid strenuous activity.
Days 3–7
Most men return to desk work within 2–3 days. Swelling and bruising begin to settle. Continue avoiding heavy lifting and vigorous exercise.
Weeks 2–4
Full recovery for most men. You can resume sexual activity when comfortable — typically around 7–10 days. Continue using contraception until semen analysis confirms clearance at 12+ weeks.
Sexual Activity and Contraception After Vasectomy
You can resume sexual activity when you feel comfortable – typically around 7-10 days after the procedure, once any discomfort has settled.
Critical: Continue using contraception until you have written clearance from me.
I arrange your post-vasectomy semen test at 12+ weeks (and typically after around 20 ejaculations). You must keep using contraception until you have written clearance. Some labs can clear you with no sperm seen, or with a very small number of non-moving sperm — I'll explain exactly what your result means.
Whilst vasectomy is a safe procedure, like any surgery, complications can occur. I believe in complete transparency about risks, however uncommon:
Common (Occurring in a Meaningful Proportion of Cases)
Bruising and swelling:
Almost all patients experience some degree of this, typically resolving within 1-2 weeks
Discomfort:
Mild to moderate discomfort is normal for the first few days, managed with over-the-counter pain relief
Small haematoma:
Minor blood collections may form but usually resolve without intervention
Uncommon Complications
Infection:
Can occur in a small proportion of cases, treated with antibiotics
Sperm granuloma:
A lump formed by sperm leaking from the cut vas, usually painless but occasionally requiring treatment
Epididymal congestion:
A feeling of fullness or aching that may persist for weeks or months in some men, typically resolves spontaneously
Rare But Important Complications
Chronic scrotal pain:
Research suggests ongoing pain affects a small minority of men post-vasectomy. Most cases are mild, but in rare instances, it can be more troublesome
Vasectomy failure:
The vas can rarely reconnect spontaneously (recanalization), though this is uncommon. This is why post-vasectomy semen analysis is essential
When to Contact Me Urgently:
Severe pain not controlled by regular painkillers
Fever or feeling generally unwell
Increasing swelling or redness
Discharge from the wound
Rapidly expanding haematoma
I provide you with my contact details and ensure you know how to reach me if concerns arise. My commitment to intrinsic ethics means I want to hear about any complications immediately, regardless of how minor they might seem – early intervention prevents problems from escalating.
Effectiveness and Success Rates
Vasectomy is the gold standard for permanent male contraception. It exceeds 99% effectiveness once clearance is confirmed by semen analysis.
What Makes Vasectomy So Effective?
Unlike other contraceptive methods that require ongoing adherence or can fail due to user error, vasectomy provides permanent, passive protection once clearance is achieved. There's no pill to remember, no device to check, and no failure due to improper use.
The key is confirming that your semen no longer contains sperm through post-procedural semen analysis. Until then, you must continue using alternative contraception.
Understanding Failure Rates and Recanalization
Whilst vasectomy is highly effective, it's not absolutely perfect. Two types of failure can occur:
Early Failure
This occurs when sperm persist in the semen analysis performed at 12+ weeks post-procedure. This happens in a small proportion of cases and may require:
Further semen samples to confirm persistence
Rarely, a repeat procedure to address the technical issue
Late Failure (Recanalization)
Even more rarely, the vas deferens can spontaneously reconnect months or years after a successful vasectomy. This phenomenon, called recanalization, is uncommon but documented. This is why I recommend periodic checking if you have any concerns, especially if your partner experiences an unexpected pregnancy.
My Approach to Minimising Failure: I use meticulous surgical technique including adequate length removal and secure sealing of the vas ends. However, even with perfect technique, biology can occasionally find a way. This is why post-procedure semen analysis is mandatory, not optional.
Comparing Contraceptive Options
It helps to compare vasectomy against other contraceptive methods:
Vasectomy: >99% effective (typical use). Once clearance confirmed; permanent.
Condoms: 82% effective (typical use). User-dependent; provides STI protection.
Withdrawal: 78% effective (typical use). Highly user-dependent; not recommended.

Frequently Asked Questions
No. Vasectomy does not affect testosterone production, erectile function, orgasm, or sexual sensation. Your testicles continue producing testosterone normally because vasectomy only blocks sperm transport – it doesn't affect the hormonal function of the testicles or the blood supply that delivers testosterone to your body.
Research has consistently shown that men report no changes in sexual function or satisfaction after vasectomy. In fact, some men report improved sexual satisfaction due to the freedom from pregnancy concerns. Some men do experience changes in libido over time, but these are related to ageing, health status, relationship factors, or other life circumstances – not the vasectomy itself.
No noticeable difference. Sperm account for only 2-5% of ejaculate volume. The rest comes from the seminal vesicles and prostate, which continue functioning normally. Your ejaculate will look, feel, and be the same volume as before – the only difference is that it won't contain sperm, which isn't visible anyway.
Your testicles continue producing sperm after vasectomy, but the sperm are simply reabsorbed by your body. This is a completely natural and safe process – your body has been reabsorbing excess sperm throughout your adult life. The immune system recognises and processes these cells without any adverse effects.
Vasectomy reversal (vasovasostomy) is technically possible but should not be relied upon. Success rates vary depending on:
Time since vasectomy: Success rates are higher within the first few years
Surgical technique and surgeon expertise
Individual factors including partner's age and fertility
Even when sperm return to the ejaculate after reversal, pregnancy isn't guaranteed. Reversal is also more complex and expensive than the original vasectomy.
My advice: Only proceed with vasectomy if you're certain about permanent contraception. If there's any doubt, consider long-acting reversible contraception instead.
Vasectomy is not immediately effective. Sperm can remain in your reproductive tract for several months after the procedure. You must continue using alternative contraception until I confirm your semen is sperm-free through analysis.
I arrange your post-vasectomy semen test at 12+ weeks (and typically after around 20 ejaculations). Some men require additional samples if sperm persist. You are considered sterile only when semen analysis shows no sperm (azoospermia) or, depending on the laboratory protocol, very rare non-motile sperm below a specified threshold. I'll explain exactly what your result means when we review it together.
This is critically important: Unintended pregnancies have occurred because couples stopped using contraception before clearance was confirmed. Please take this seriously.
No. Vasectomy provides no protection against STIs. If STI protection is needed, continue using condoms regardless of vasectomy status. This is particularly important if you're not in a mutually monogamous relationship or if either partner has potential exposure to STIs.
This has been extensively researched. Current evidence does not support an association between vasectomy and increased risk of prostate cancer, testicular cancer, cardiovascular disease, or other conditions. Multiple large-scale studies and systematic reviews have found no causal relationship.
Early studies that suggested a possible link had methodological limitations and have not been supported by subsequent higher-quality research. Major medical organisations, including the American Urological Association and British Association of Urological Surgeons, agree that vasectomy does not increase disease risk.
The cost of vasectomy includes your initial consultation, the procedure itself using the no-scalpel access technique under local anaesthetic, post-operative care, and follow-up semen analysis to confirm success.
For specific pricing information and what's included in your care package, please contact us or ask during your initial consultation. I believe in complete transparency about costs before you commit to proceeding.
These concerns are understandable and worth discussing openly. Let me address the facts:
Physical masculinity: Vasectomy doesn't affect testosterone, muscle mass, body hair, voice, or any other masculine characteristics. These are all controlled by testosterone from the testicles, which continues normally after vasectomy.
Sexual function: Research consistently shows no changes in erectile function, orgasm, or sexual satisfaction. Many couples report improved intimacy due to freedom from pregnancy anxiety.
Psychological aspects: Whilst vasectomy is a physical procedure, fertility can be emotionally complex for some people. If either partner has concerns about how vasectomy might affect your relationship or self-perception, I encourage you to discuss these openly, perhaps with professional support if needed.
I welcome partners to attend consultations so we can address concerns together and ensure both parties are comfortable with the decision.
Myths vs Facts About Vasectomy
Vasectomy attracts many myths. Here are the facts:
Common Vasectomy Myths — Debunked
✓ Fact: Vasectomy does not affect hormone production or libido. Your testicles continue producing testosterone normally — vasectomy only blocks the transport of sperm. Testosterone levels, sex drive, erections, and orgasm are completely unaffected. Research consistently shows no changes in sexual function or satisfaction after vasectomy.
✓ Fact: Vasectomy and castration are entirely different procedures. In a vasectomy, only the vas deferens (the sperm-carrying tubes) is cut and sealed — the testicles remain completely intact. Your testicles continue to produce testosterone and sperm normally. Nothing is removed.
✓ Fact: Most men return to desk work within 2–3 days. The no-scalpel technique minimises tissue trauma, meaning recovery is faster than many expect. Physical or manual labour may require a week off, and you should avoid strenuous exercise for about a week. Most men describe the experience as far less disruptive than anticipated.
✓ Fact: Reversal is technically possible but success rates decline significantly over time and are never guaranteed. Reversal is a more complex, expensive procedure, and even when sperm return to the ejaculate, pregnancy is not assured. Always treat vasectomy as a permanent decision. If you have any doubts about future fertility, consider long-acting reversible contraception instead.
✓ Fact: Ejaculation and orgasm are completely unchanged after vasectomy. Sperm makes up less than 5% of semen volume — the rest comes from the seminal vesicles and prostate, which continue functioning normally. The volume, appearance, and sensation of ejaculation remain the same. Many couples actually report improved intimacy due to freedom from pregnancy anxiety.
✓ Fact: No evidence links vasectomy to prostate cancer, testicular cancer, or any other malignancy. Multiple large-scale studies and systematic reviews have found no causal relationship. Major medical organisations including the American Urological Association and British Association of Urological Surgeons confirm that vasectomy does not increase cancer risk.
