Erection Problems Not Improving? When P Shot Treatment May Be Considered and What to Expect

6 February 2026

8 min read

If erection problems keep happening, it can be frustrating and can affect confidence, relationships, and wellbeing. It is also important medically, because erectile dysfunction (ED) can sometimes be linked to underlying health issues such as blood vessel problems. NHS guidance advises seeing a GP or sexual health clinic if erection problems continue, as it may be a sign of a treatable health condition.

This is often where people begin searching terms like p shot treatment, p shot, p-shot, pshot, and priapus shot, especially if they feel standard options have not helped or they want to explore private alternatives in the UK.

This article explains the problem first, then the safe, evidence-led way to think about a P Shot (Priapus Shot), including who it may be discussed for, what is realistic, and the questions to ask before booking.

Why erection problems sometimes do not improve

ED is rarely caused by one single issue. The British Society for Sexual Medicine (BSSM) describes ED as the persistent inability to attain and or maintain an erection sufficient for satisfactory sexual performance, with causes that can include vascular, neurological, hormonal, metabolic, and psychological factors.

Common reasons ED may persist include:

1) Underlying vascular health

Erections depend on healthy blood flow. NHS Inform notes that narrowed blood vessels are a common cause of ED and are linked with cardiovascular disease.
That is why ED should not be treated as purely a performance issue.

2) Hormonal factors

Low testosterone is not the only cause of ED, but it can contribute, especially with reduced desire, fatigue, or reduced morning erections. BSSM guidance highlights the need to evaluate endocrine risk factors in newly presenting patients.

3) Medication effects and lifestyle contributors

Some blood pressure medicines, antidepressants, smoking, alcohol use, sleep problems, obesity, and poorly controlled diabetes can all contribute.

4) Performance anxiety and stress

Psychological factors can worsen ED even when there is an underlying physical driver.

5) Incorrect diagnosis or unrealistic expectations

Sometimes the real issue is penile curvature, pain, pelvic floor dysfunction, relationship factors, or a mismatch between expectations and normal age-related changes.

The safe first step before any private treatment

Before considering a p shot treatment or any injectable therapy, it is best practice to do a proper ED assessment. NICE Clinical Knowledge Summaries include cardiovascular risk stratification as part of ED assessment.
BSSM guidance emphasises evaluation for cardiovascular and endocrine risk factors.

If you have not had a clinical assessment recently, start there. It improves safety and helps you avoid paying for a treatment that does not match the cause of your symptoms.

Evidence-based options that usually come first

Most clinical pathways consider these before experimental or restorative injections:

Lifestyle improvements where relevant (weight, smoking, alcohol, exercise, sleep)
Addressing mental health, stress, and relationship factors
Oral PDE5 inhibitor medicines when appropriate, prescribed safely
Vacuum erection devices or other established options when indicated
Testosterone assessment if clinically appropriate

If these have not worked, or you cannot use them safely, that is when some patients explore private options such as PRP, often marketed as the Priapus Shot.

What is P Shot treatment?

A P Shot (also written as P-Shot or Pshot) is a clinic term that typically refers to platelet-rich plasma (PRP) injections into penile tissue.

PRP is made from a sample of your own blood, processed to concentrate platelets. The rationale is that platelet-derived growth factors might influence tissue signalling and repair pathways, but the clinical evidence in ED is still developing and is not fully standardised.

The key problem: marketing is ahead of the evidence

Many people search for phrases like penile injection growth or “p injection” because online claims can imply guaranteed enlargement or major performance transformation. High-quality medical sources advise caution.

Cleveland Clinic notes that clinical trials do not show that the P Shot improves erections and highlights that evidence is limited.

The Sexual Medicine Society of North America (SMSNA) position statement concludes that restorative therapies, including PRP, should be reserved for clinical trials until stronger evidence is available.

The European Association of Urology (EAU) guideline chapter on ED notes PRP has been investigated and reports only mild improvements, stating evidence is insufficient to recommend routine use.

So the safe way to frame P Shot treatment is:

It may help some men with certain types of ED
It is not a guaranteed solution
It should be offered with transparent consent and realistic expectations

When might P Shot treatment be discussed?

In a careful clinical setting, PRP-based approaches may be discussed for adults who:

Have mild to moderate ED, often described as organic or vasculogenic
Have tried first-line treatments without adequate benefit or cannot tolerate them
Understand the evidence limitations and accept uncertainty
Want a non-surgical option and are making an informed choice

This is a discussion, not an automatic recommendation

What happens during a typical P Shot appointment?

Protocols vary by clinic, but a credible pathway usually includes:

1) Clinical assessment

A proper consultation should check:

ED history and severity
Cardiovascular and metabolic risk factors
Medication review
Hormonal considerations if indicated
Mental health and relationship factors

2) Blood draw and PRP preparation

PRP is prepared from your blood using a centrifuge. One major limitation in the research is that PRP products can vary a lot depending on the preparation method, which makes it harder to compare results across studies.

3) Anaesthetic and injection

A local anaesthetic approach may be used. The injection should be done using sterile technique.

What results are realistic?

If benefit occurs, it is usually described as gradual rather than immediate.

Some reviews and studies report improvements in erectile function scores after PRP, but authors also highlight study differences, short follow-up, and the need for better trials.
EAU guidance remains cautious and does not recommend routine use based on current evidence.
SMSNA advises restricting to clinical trials.

Practical expectation-setting

A clinic should not promise outcomes
Improvement, if it happens, may be modest
Not everyone responds
Claims of guaranteed “penile injection growth” should be treated with scepticism unless supported by robust evidence for your specific situation

Safety and side effects

Even though PRP is derived from your own blood, injections still carry risks:

Bruising, swelling, tenderness
Temporary discomfort
Infection risk (rare, but serious)

A clinic should provide written aftercare advice and clear instructions for urgent symptoms.

P Shot UK and P Shot London: what to check before booking

If you are searching p shot uk, pshot uk, or p shot london, the most important difference between providers is clinical governance, not marketing.

A strong clinic should be able to answer:

Who will assess me and who will perform the injection?
Is the clinician appropriately registered and experienced in ED assessment?
What is my likely ED cause and what has been ruled out?
What PRP system is used and how is it standardised?
What outcomes are realistic for my case and how will we measure success?
What are the risks and what is the aftercare plan?
What is the plan if there is no improvement?

In the UK context, professional bodies have discussed the legal and regulatory status of PRP and the importance of following appropriate regulatory frameworks.

If erection problems are not improving, the safest first step is a proper medical assessment, because ED can be linked to underlying vascular or metabolic health issues.
P Shot treatment, typically PRP injections, is marketed as a restorative option, but leading guidance remains cautious. EAU guidance does not recommend routine use due to insufficient evidence, and SMSNA advises restricting PRP and similar restorative therapies to clinical trials.

If you still want to explore p shot treatment in the UK, choose a medically led clinic, ask detailed questions, and make sure consent documents clearly explain the uncertainties, risks, and realistic outcomes.

FAQs

Is P Shot treatment the same as PRP?

In most clinics, yes. “P Shot” and “Priapus Shot” are usually marketing terms for PRP injections. Always confirm what is being injected and how it is prepared.

If my ED is not improving, should I try a P Shot next?

Not automatically. NHS guidance recommends seeing a GP or sexual health clinic if erection problems keep happening, as it may be a sign of an underlying health condition.
Evidence-based options and a proper assessment usually come first.

Does the Priapus Shot work for erectile dysfunction?

Evidence is mixed and still developing. EAU guidance notes only mild improvements and says evidence is insufficient to recommend routine use.
SMSNA recommends restorative therapies like PRP be limited to clinical trials until stronger evidence exists.

Is P Shot UK treatment available on the NHS?

It is generally offered privately rather than through standard NHS pathways. If you are considering it, prioritise medical assessment and informed consent.

Is P Shot London safe?

Safety depends on correct patient selection, sterile technique, and appropriate follow-up. Infections are rare but possible with any injection.

Does a p injection cause penile injection growth?

Be cautious. Claims of guaranteed growth are not supported by strong clinical trial evidence in reputable medical sources, and major guidance focuses on ED outcomes rather than guaranteed enlargement.
