What is the PRP P-Shot for erectile dysfunction?

The P-Shot (Priapus Shot) is a procedure in which platelet-rich plasma (PRP) is injected into specific areas of the penis. PRP is prepared by taking a small sample of your blood, spinning it in a centrifuge to concentrate the platelets, and then injecting the resulting plasma back into the penile tissue. Platelets contain growth factors that are thought to stimulate tissue repair, improve blood vessel formation, and enhance sensitivity.

The procedure is usually performed in a private clinic under local anaesthetic. Proponents suggest that the P-Shot may help men with erectile dysfunction by promoting new blood vessel growth and improving the health of penile tissue. However, it is important to note that the P-Shot is not a licensed medicine in the UK and is not regulated by the Medicines and Healthcare products Regulatory Agency (MHRA) as a treatment for ED. It is classified as a medical procedure rather than a pharmaceutical intervention.

Because the P-Shot is not a licensed treatment, it is not available on the NHS and is not included in NICE guidelines for the management of erectile dysfunction [2]. Men considering this option should seek detailed information from a qualified practitioner and be aware that the evidence base is still developing.

How does the PRP P-Shot work for erectile dysfunction?

The theory behind the P-Shot is that the growth factors in platelet-rich plasma can stimulate the body's natural healing and regeneration processes. When injected into the penis, these growth factors are believed to encourage the formation of new blood vessels (angiogenesis), improve the health of existing blood vessels, and potentially increase the sensitivity of nerve endings. Better blood flow is central to achieving and maintaining an erection, so any improvement in vascular health could, in principle, help with ED.

Practitioners typically inject PRP into the shaft and head of the penis after applying a local anaesthetic cream or injection to minimise discomfort. The procedure usually takes around 30 to 60 minutes, and patients are often advised that they may need more than one session to see any benefit. Some clinics suggest that effects may develop gradually over several weeks as tissue regeneration occurs.

It is important to understand that the P-Shot is not a quick fix like oral ED tablets. While tablets such as sildenafil work within an hour by increasing blood flow during sexual stimulation, the P-Shot aims to improve the underlying tissue health over time. There is currently limited high-quality clinical trial evidence to confirm how effective this approach is, and results may vary widely between individuals.

The role of platelets and growth factors

Platelets are small blood cells that play a key role in clotting and wound healing. They release growth factors such as platelet-derived growth factor (PDGF), vascular endothelial growth factor (VEGF), and transforming growth factor-beta (TGF-β), which are involved in tissue repair and blood vessel formation. The idea is that concentrating these factors and delivering them directly to penile tissue may stimulate regeneration and improve erectile function. However, the exact mechanisms and the extent to which these growth factors can reverse or improve ED in humans are still being researched.

Who might consider the PRP P-Shot for erectile dysfunction?

The P-Shot is sometimes considered by men who have not responded well to oral ED tablets, or who are looking for a treatment that does not involve taking medication. It may also appeal to those interested in regenerative medicine approaches or who prefer a procedure-based option. Some men with mild to moderate ED, particularly if related to reduced blood flow or age-related changes in penile tissue, may be curious about whether the P-Shot could help.

However, because the P-Shot is not a licensed treatment and the evidence for its effectiveness is limited, it is not recommended as a first-line option for erectile dysfunction. NICE guidance and the European Association of Urology guidelines recommend starting with lifestyle changes (such as stopping smoking, reducing alcohol, losing weight, and increasing exercise) and, if needed, a trial of a PDE5 inhibitor tablet such as sildenafil or tadalafil [2][8]. These tablets have been extensively studied in clinical trials and are known to be effective and safe for the majority of men with ED.

Men considering the P-Shot should have a thorough discussion with a qualified healthcare professional, ideally one experienced in sexual health or urology. It is also important to rule out underlying causes of ED, such as diabetes, high blood pressure, or cardiovascular disease, which may require specific medical treatment. Seeing your GP for an initial assessment is strongly encouraged, as ED can be an early warning sign of heart disease [1].

When the P-Shot may not be suitable

The P-Shot may not be appropriate for men with certain medical conditions, such as blood clotting disorders, active infections, or those taking anticoagulant medicines. Men with severe ED caused by significant nerve damage (for example, after prostate surgery) or anatomical problems may not see benefit from a regenerative approach. As with any procedure, there are risks, including bruising, pain, infection, and scarring. It is essential to choose a reputable, qualified practitioner and to have realistic expectations about what the treatment can achieve.

What you need to know

• The PRP P-Shot is not a licensed ED treatment in the UK and has limited clinical trial evidence
• Oral ED tablets like sildenafil and tadalafil are proven, affordable, and recommended as first-line treatment
• The P-Shot is only available privately and costs significantly more than licensed tablets
• Always see your GP for new ED, as it can be an early sign of heart disease or diabetes

Effectiveness and evidence for the PRP P-Shot

The evidence base for the P-Shot in treating erectile dysfunction is still in its early stages. Most of the published studies are small, uncontrolled, or observational, and there are few large, randomised controlled trials comparing the P-Shot with placebo or standard treatments. Some small studies and case reports have suggested that men may experience improvements in erectile function, penis size, or sensitivity after PRP injections, but these findings need to be confirmed in larger, well-designed trials.

In contrast, oral PDE5 inhibitors such as sildenafil have been studied in thousands of men in rigorous clinical trials. Sildenafil, for example, was shown to improve erections in a significant proportion of men with ED in landmark studies published in the late 1990s [9]. Tadalafil, vardenafil, and avanafil have similarly strong evidence supporting their use [2][8]. Because of this robust evidence, these tablets are the recommended first-line medical treatment for ED in the UK.

Men considering the P-Shot should be aware that it is an experimental or emerging treatment, and that results are not guaranteed. It is also worth noting that the P-Shot is not regulated in the same way as licensed medicines, so the quality and consistency of the procedure may vary between clinics. If you are interested in the P-Shot, ask your practitioner about the evidence they rely on, the success rates they have observed, and any potential risks or side effects.

Side effects and risks of the PRP P-Shot for erectile dysfunction

Because the P-Shot involves injecting a substance into the penis, there are potential side effects and risks to consider. Common side effects include temporary bruising, swelling, redness, and discomfort at the injection site. Some men may experience pain during or after the procedure, although local anaesthetic is usually used to minimise this. There is also a small risk of infection, as with any injection, and a risk of scarring or changes in penile shape if the procedure is not performed correctly.

More serious complications are rare but can include prolonged pain, nerve damage, or the formation of scar tissue (fibrosis) that could potentially worsen erectile function. There have been occasional reports of priapism (a prolonged, painful erection lasting more than four hours) following penile injections, although this is more commonly associated with other injection treatments such as alprostadil [7]. If you experience an erection lasting more than four hours after any ED treatment, you should seek urgent medical help.

It is also important to consider that because PRP is derived from your own blood, there is no risk of allergic reaction to the plasma itself. However, the safety and long-term effects of repeated PRP injections into penile tissue are not yet fully understood. Choosing a qualified, experienced practitioner and ensuring that the procedure is carried out in a clean, clinical environment can help to minimise risks.

Comparing risks with oral ED tablets

Oral ED tablets such as sildenafil and tadalafil are generally well tolerated, with the most common side effects being headache, flushing, indigestion, and nasal congestion [3][4]. Serious side effects are rare when the tablets are used correctly and after a proper medical assessment. The P-Shot, being a procedural intervention, carries different risks related to the injection itself. For many men, the convenience, established safety profile, and strong evidence base of oral tablets make them a more straightforward first choice.

When to get urgent help

• Erection lasting more than 4 hours (priapism) – go to A&E immediately
• Sudden loss of vision or hearing after any ED treatment – seek urgent medical help
• Chest pain during sex – stop and call 999 if pain does not resolve quickly
• Severe pain, swelling, or signs of infection after a penile injection – contact your GP or go to A&E
• New or worsening erectile dysfunction – see your GP, as it can be an early sign of heart disease or diabetes

Call 999 or go to A&E in an emergency, or contact NHS 111 for urgent advice.

NHS availability and cost of the PRP P-Shot

The PRP P-Shot is not available on the NHS because it is not a licensed treatment for erectile dysfunction and is not included in NICE guidelines [2]. It is offered only in private clinics, and the cost can vary widely depending on the clinic, the practitioner's experience, and the number of sessions recommended. Prices typically range from several hundred to over a thousand pounds per session, and some clinics suggest that multiple sessions may be needed for optimal results.

In contrast, oral ED tablets are available on the NHS for men with certain underlying conditions (such as diabetes, prostate cancer, or severe distress related to ED), although many men choose to obtain them privately due to NHS prescribing restrictions. Private prescriptions for generic sildenafil and tadalafil are widely available and are much more affordable than the P-Shot. For example, at Cured Pharmacy, generic sildenafil starts at £0.45 per tablet (or £0.36 with the code Ednew on your first order), and generic tadalafil starts at £7.95 (or £6.36 with Ednew).

When considering the cost of the P-Shot, it is worth weighing the expense against the strength of the evidence and the availability of proven, cost-effective alternatives. Many men find that a trial of oral ED tablets, combined with lifestyle changes, is a practical and effective first step. If tablets are not suitable or effective, other licensed options such as alprostadil injections or vacuum erection devices may be considered before exploring experimental treatments.
