LONDON, May 2026 — As awareness of regenerative medicine in men's health continues to grow across the UK, Dr SNA Clinic — a medically led private practice based on Wimpole Street, Marylebone — is drawing attention to one of the most consistently under-discussed causes of erectile dysfunction: long-term smoking and the vascular damage it produces.
With an increasing number of London-based men researching treatments such as the P-Shot® (Priapus Shot®), Dr Syed Nadeem Abbas, founder and lead clinician at Dr SNA Clinic, is calling for greater public understanding of the physiological mechanisms that drive smoking-related ED — and greater scrutiny of the clinics offering to treat it.

The Vascular Reality Behind Smoking and ED

Erectile dysfunction in smokers is rarely a hormonal issue. It is predominantly a vascular one.
Nicotine acts as a vasoconstrictor, narrowing blood vessels and restricting the volume of blood available to penile tissue during arousal. Long-term tobacco exposure accelerates atherosclerosis — the accumulation of arterial plaque — and critically impairs the endothelium, the inner lining of blood vessels responsible for producing nitric oxide, the molecule that enables arterial dilation during an erection.
The European Association of Urology identifies smoking as one of the most consistently evidenced modifiable risk factors for erectile dysfunction, with risk correlating directly to duration and intensity of use.
"Many men arrive at the clinic having tried oral medications that haven't worked as expected," said Dr Abbas. "In long-term smokers, endothelial damage reduces nitric oxide availability — which is precisely the mechanism those medications depend on. This is not a failure of the drug. It is a signal that the underlying vascular damage needs to be addressed more directly."

What the P-Shot® Offers — and What It Requires to Work Properly

The Priapus Shot®, commonly referred to as the P-Shot®, uses platelet-rich plasma (PRP) — concentrated from the patient's own blood — to stimulate tissue regeneration, promote neovascularisation, and improve blood flow within penile tissue. The treatment draws on the same regenerative principles applied in orthopaedic and wound-care medicine and is particularly relevant for men whose erectile difficulties have a vascular basis.
However, Dr Abbas cautions that the outcome of P-Shot® treatment depends heavily on how it is delivered.
"The growth factor concentration in the PRP, the precision of the injection, and the anatomical knowledge of the practitioner are all variables that directly affect results," he said. "Ultrasound guidance, CE-marked centrifuge systems, and genuine medical training are not optional extras — they are the baseline for a treatment of this kind to be conducted safely and effectively."
Dr SNA Clinic administers P-Shot® treatment using ultrasound-guided injection technique and CE-certified PRP processing systems, within a clinical environment structured around patient safety and transparent informed consent.

A Growing Concern: The Quality Gap Across UK Clinics

The rising popularity of P-Shot® treatment across the UK has brought with it a significant disparity in how the procedure is being offered. Price points vary from under £400 to well above £1,500, with patients frequently unable to identify what accounts for the difference.
Dr Abbas points to several factors that informed patients should verify before booking:
The centrifuge system used and the PRP concentration it achieves; whether ultrasound guidance is employed during injection; the clinical background and specific training of the administering practitioner; and whether the clinic operates under a framework that includes aftercare and clinical review.
"The men researching this treatment are often already anxious and already uncertain," said Dr Abbas. "They deserve clear answers to direct questions. Any clinic confident in its standards should be able to provide them without hesitation."
