P Shot (Priapus Shot): What It Is, How It Works, Benefits, and Who It’s For
The “P Shot” (also called the “Priapus Shot”) is a term commonly used in private clinics to describe platelet-rich plasma (PRP) injections into penile tissue. People typically search for it using keywords like p shot, p-shot, pshot, and priapus shot, often in the context of erectile dysfunction (ED), reduced sensitivity, or performance confidence.
Because this is a medical and sensitive topic, it is important to be clear about what is known, what is uncertain, and what is still being studied. Major professional guidance notes that PRP injections for ED may show mild improvements, but the evidence is not yet strong enough for routine recommendation, and some professional bodies advise these treatments should be limited to clinical trials.
This article explains the treatment in a factual, UK-safe way, including realistic expectations, safety considerations, and questions to ask before booking a consultation.
What is a P Shot?
A P Shot is essentially a brand or clinic term for a PRP injection procedure. PRP is made from a small sample of your own blood. The blood is processed to concentrate platelets, which contain growth factors and signalling proteins involved in tissue healing processes. This concentrated plasma is then injected into specific penile areas depending on the clinic’s protocol.
Clinics may use “P Shot”, “P-Shot”, “Pshot”, “Priapus Shot”, or “P injection” to describe similar PRP-based treatments. It is worth confirming what exactly is being injected, how it is prepared, and where it is injected.
What is PRP and why is it used?
Platelet-rich plasma (PRP) is an autologous blood product, meaning it comes from your own blood. PRP has been used in multiple medical fields, although evidence quality varies by condition.
In sexual medicine, the rationale is that PRP might support tissue repair mechanisms and blood vessel function. The Sexual Medicine Society of North America (SMSNA) describes PRP as containing growth factors and a “healing scaffold” conceptually, but stresses that evidence and standardisation are insufficient and urges restricting restorative therapies (including PRP) to clinical trials for now.
What is the P Shot used for?
People most commonly seek a p shot treatment for:
- Erectile dysfunction (ED), especially mild to moderate, typically described as organic or vasculogenic ED
- Reduced erectile rigidity
- Reduced penile sensitivity (claims vary by provider)
Some providers also discuss it for Peyronie’s disease. However, patient-facing medical resources caution that there is not good scientific evidence to support P Shot claims for ED or Peyronie’s disease in routine practice.
Professional guidance is cautious. For example, the European Association of Urology (EAU) guidelines state that intracavernous PRP has led to mild improvement in erectile function among patients with organic ED, but evidence is insufficient to recommend its use.
How does a P Shot work?
This is the most important credibility point: the exact mechanism in humans is not fully established.
The proposed idea is that PRP might influence local tissue signalling related to blood vessels and healing. Reviews summarise potential mechanisms, but also highlight the limitations and variability in PRP preparation and study design.
In practical terms, if PRP helps, it is expected to do so gradually, over time, rather than acting like a fast medication.
What happens during a P Shot appointment?
Protocols vary by clinic, but a credible pathway should include:
1) Proper assessment first
A clinician should confirm whether ED is likely psychogenic, organic, or mixed, and screen for contributing factors like cardiovascular risk, diabetes, testosterone issues, medication effects, sleep, and mental health. ED can be an early marker of vascular disease, so proper assessment matters.
2) Blood draw and PRP preparation
- A small blood sample is taken
- It is centrifuged to separate components
- PRP is prepared for injection
A key quality point: PRP is not one single product. Different machines and protocols produce different platelet concentrations, and studies are heterogeneous. This is one reason evidence is still uncertain.
3) Anaesthetic and injection
Clinics may use topical anaesthetic or a nerve block. The injection is performed with sterile technique.
What results can you realistically expect?
This needs careful wording.
What studies suggest
Systematic reviews and meta-analyses in ED have reported improvements in erectile function scores with PRP compared with placebo, but they also highlight heterogeneity and the need for larger, higher-quality trials and longer follow-up.
The EAU guideline summary is conservative: mild improvement has been observed, but evidence is insufficient to recommend routine use.
The SMSNA position statement is more restrictive: restorative therapies like PRP should be reserved for clinical trials until stronger evidence exists.
What this means for patients
- Some men may notice improvement
- Some may notice no meaningful change
- If improvement happens, it is usually described as gradual, over weeks to a few months
- It should not be presented as guaranteed or permanent
A clinic should not promise specific outcomes like “penile injection growth” or guaranteed enlargement. Be especially cautious with any marketing language that implies certainty.
Who may be a good candidate?
A clinician may consider discussing PRP-based P Shot protocols for adults who:
- Have mild to moderate erectile dysfunction, especially vasculogenic causes
- Have tried first-line options (lifestyle, PDE5 inhibitors such as sildenafil where appropriate) with limited benefit or tolerance
- Want to explore non-surgical options and understand evidence limitations
- Have realistic expectations and accept that results are not guaranteed
This should always be individualised. ED is not one condition, and response can vary widely.
Who should avoid it or take extra caution?
You should not book a P Shot without proper medical screening if you have:
- A bleeding disorder
- Current infection or skin infection in the genital area
- Significant penile pain, lumps, ulcers, or unexplained changes that need urology assessment
- Unstable cardiovascular disease or you are advised to avoid sexual activity
Also discuss anticoagulant or antiplatelet medicines with the clinician, as injection-related bruising and bleeding risk may be higher.
Safety and side effects
Even though PRP uses your own blood, injection risk still exists.
Potential side effects can include:
- Temporary pain or tenderness at injection sites
- Bruising or swelling
- Local inflammation
- Infection (rare, but serious when it occurs)
Because evidence is still emerging, it is important that clinics discuss uncertainties clearly and obtain informed consent aligned with UK standards.
Is P Shot available in the UK?
People searching p shot uk or pshot uk usually find it offered through private clinics rather than the NHS.
From a UK regulatory perspective, PRP has been discussed as a medicinal product in professional guidance updates, and the Chartered Society of Physiotherapy (CSP) has published guidance updates and commentary on the regulatory position, including the fact that medical practitioners (doctors) have exemptions in certain circumstances.
The practical takeaway for patients is simple:
- Choose a medically led clinic
- Make sure you receive a proper assessment and written consent process
- Ask exactly what is being offered and what evidence supports the claims for your situation
P Shot London: what to check before booking
If you are searching p shot london, quality varies. Before you pay for a consultation, ask:
- Who will assess me and who will inject me?
- Is the clinician medically qualified and registered?
- What diagnosis are you treating and how do you confirm it?
- What PRP preparation method do you use and is it standardised?
- What outcomes are realistic for my case, and what is the plan if I do not respond?
- What risks are included in the consent form, including infection risk?
- What aftercare and follow-up are included?
A credible clinic will answer these clearly and will not pressure yo
The P Shot (Priapus Shot) is commonly used to describe PRP injections offered privately for erectile concerns. Some studies and reviews suggest possible mild improvements in erectile function, but leading professional guidance remains cautious due to limited and heterogeneous evidence.
If you are considering p shot treatment in London or elsewhere in the United Kingdom, prioritise a medically led assessment, transparent consent, realistic expectations, and a clinic that can clearly explain what evidence supports their approach for your specific situation.
FAQs
Is the P Shot the same as PRP?
In most clinics, yes. “P Shot” is typically a clinic term for PRP injections into penile tissue. Always confirm what is being injected and how it is prepared.
Does the P Shot treat erectile dysfunction?
Evidence suggests PRP injections may provide mild improvements in erectile function in some men, but major guidance notes the evidence is still insufficient to recommend routine use, and some professional bodies advise restricting it to clinical trials.
How long does it take to see results?
If there is benefit, it is typically described as gradual over weeks to a few months, not instant. Outcomes vary and are not guaranteed.
Is P Shot UK treatment regulated?
PRP is discussed in UK professional guidance in relation to medicines regulation and who can supply or administer it in clinical settings. Choose a medically led service that provides clear consent and aftercare.
Is P Shot London safe?
Safety depends on appropriate patient selection, sterile injection technique, and proper aftercare. Any injection carries infection risk, even if uncommon.
Does a penile injection cause growth?
Be cautious with claims around “penile injection growth”. High-quality evidence does not support guaranteed enlargement claims from PRP, and reputable sources advise scepticism about strong marketing claims.
Who should not have a P Shot?
People with active infection, significant bleeding risk, or unexplained penile symptoms should avoid elective injection treatment until properly assessed by a qualified clinician.
