“I’d been told I needed to go to hospital and have a general anaesthetic… but here it was over in minutes, pain free.” (2024 patient comment)
Not every vasectomy is routine. Some men are told their case is “too difficult” for a local clinic, often due to previous surgery, scar tissue, a vasectomy reversal, or advice that only hospital admission and general anaesthetic would be safe. Yet many later discover that complexity does not automatically require a hospital setting — it requires experienced hands.
For over two decades, Thames Valley Vasectomy Services has increasingly welcomed men seeking help after being turned away elsewhere. These are men who were refused on complexity grounds, uncertain if their scarring, medical history or past experiences would prevent a safe procedure. What they often find instead is not a more invasive pathway, but a calmer and more expert one.
Men with complex needs often arrive after being warned their operation would be too difficult outside a hospital. Their stories vary, but the common question is clear:
“Am I suitable for vasectomy at all?”
Typical reasons they seek a second opinion include:
Previous vasectomy and subsequent reversal
Advice the vasectomy can only be carried out in hospital
Advice that general anaesthetic is required
These men are not seeking luxury. They are seeking someone who understands the nature of complex anatomy — someone who has seen it before.
A vasectomy after reversal or prior surgery can be more demanding. Scar tissue may alter anatomy, making the vas deferens deeper, thicker or less mobile. Some clinics refer these patients automatically to hospital. An experienced specialist, however, understands that with time, careful dissection and tailored technique, many can still be safely managed under local anaesthetic.

“For me, after a previous NHS vasectomy and a private reversal, private was the only option… and this turned out to be a really good choice.”

One of the challenges we often see is patients arriving only after multiple attempts or consultations elsewhere. Each previous procedure increases scar tissue, distorts anatomy and makes surgery progressively more complex. While we are still able to operate in many of these situations, it is far better for men with surgical history or known complexity to see a specialist first — not as a last resort. Choosing experience early can result in a shorter procedure, less discomfort and a smoother recovery.
There is a widespread assumption that complex vasectomy cases must be carried out in hospital under general anaesthetic. While general anaesthetic can be necessary — especially in cases involving certain behavioural or medical needs — it is often recommended due to lack of surgical confidence rather than true clinical necessity.
Many men who believed they required hospital facilities later discovered they were suitable for local anaesthetic. Some required additional anaesthetic injections for comfort, but still found the procedure painless and surprisingly quick:
“I expected it to be difficult, but another dose of anaesthetic made it pain free, and it was over before I knew it.” (2024 comment)
The crucial difference is judgement — knowing when to persist safely, and when hospital truly is required. The aim is never to force a complex vasectomy under local, but to avoid unnecessary escalation when it is not needed.
Although most complex cases can still be managed safely under local anaesthetic, there are rare occasions when even I after 20,000 vasectomies must advise hospital care or general anaesthetic. This is not a failure — it is a clinical decision made in the patient’s best interests. The priority is always safety, not forcing every case into clinic.
Not every complex vasectomy is the result of prior operations. Natural anatomical variations, cysts or tissue thickness can make access more technically demanding. For some providers, these findings lead to immediate referral. For specialists, they require adjustment — not abandonment.
One man noted:
“I had a large cyst, which was dealt with at the same time. I felt more comfortable afterwards.” (2024 comment)
Patients rarely see the complexity. They simply feel the composure. What appears difficult behind the scenes is experienced as calm process working with patients to achieve the desired outcome together.
Many patients who visit a specialist do so after hearing “no” elsewhere. Some were told it was too risky, others were listed for hospital waiting lists without assessment. These patients often express the same reflection:
“I had been listed with another provider who completely failed in their duties — nothing like this experience.”

“I wish I had found this clinic first.” (2019 feedback)
What they value most is not speed, but fairness — being assessed individually rather than excluded categorically.
NHS guidance identifies several conditions that may require caution before vasectomy:
Varicocele
Inguinal hernia
Cryptorchidism (undescended testis)
Anticoagulant therapy
Previous scrotal surgery
Hydrocele
BMI over 35
Drug or alcohol misuse
Many services refer all such cases to hospital by default. At Thames Valley Vasectomy Services, these criteria are recognised — but not treated as automatic exclusions.
Anticoagulant therapy may still be manageable with clinical planning and GP coordination.
Previous surgery or scar tissue requires expertise and time, not necessarily a hospital environment.
High BMI or anatomical variation may make access more delicate, but does not guarantee the need for general anaesthetic.
This is not risk-taking. It is careful selection — offering a fair opportunity to those who would otherwise be denied.
Volume creates calm. A surgeon who has performed thousands of vasectomies develops a refined understanding of anatomical variation and how to adapt technique without escalating risk. What a standard clinic sees once a year, a specialist may see every fortnight.
Patients often describe being surprised — not only at the speed, but at how uneventful the experience felt given their expectations. Complexity managed well feels ordinary.
Our pre-operative webinar is not merely informational. It is preparation. Patients learn exactly what to expect and arrive on the day knowing the process, the sequence and their role in it. For complex cases, this reduces hesitation and improves cooperation during local anaesthetic.
“The webinar made all the difference. I realised I could actually do this.” (2024 comment)
Information, in experienced practice, is part of anaesthesia.
Can I have a vasectomy after a reversal or previous vasectomy?
Yes. Redo vasectomies are more complex, but can often still be performed safely under local anaesthetic with experienced surgical technique.
I was told I need general anaesthetic — is that always true?
Not always. General anaesthetic may be necessary in select cases, but many men previously advised to have GA were safely treated under local anaesthetic following specialist assessment.
Can I have a vasectomy if I’m on anticoagulants?
In many cases, yes. With proper planning and communication, anticoagulant therapy does not automatically prevent vasectomy.
Do scar tissue or previous operations mean I must go to hospital?
No. Scar tissue demands time and precision but does not automatically require hospital admission.
What if I’ve been refused elsewhere?
A refusal elsewhere does not mean it cannot be done. It may simply mean you have not yet been assessed by a specialist.
A complex vasectomy does not have to become a complicated experience. With proper evaluation, it may still be managed safely, calmly and without general anaesthetic. The goal is not to avoid hospital at all costs — it is to reserve it only for those who truly need it.
Many men told they were unsuitable for local anaesthetic completed their vasectomy in minutes, not hours. What changed was not their anatomy, but who was holding the instruments.
“I was nervous because of my past surgery, but I realised very quickly I was in experienced hands.”

If you have been told your vasectomy is too complex, too risky or requires hospital care, you are welcome to seek a second opinion.
No assumptions. No automatic refusals. Just an honest and experienced assessment of whether your case can be safely managed under local anaesthetic — or whether hospital referral is genuinely required.
A complex case should not end with rejection. It should begin with evaluation.
