P (Priapus Shot)

P Shot: What It Is, What It’s Used For, and Who It’s For

14 February 2026

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?

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.

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.

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?

What studies suggest: systematic reviews and meta-analyses have reported improvements in erectile function scores with PRP compared with placebo, but also highlight heterogeneity and need for better trials.

Practical meaning:

Some men may notice improvement
Some may notice no meaningful change
If improvement happens, it is usually gradual, over weeks to a few months
It should not be presented as guaranteed or permanent

Safety and side effects

Potential side effects can include temporary pain, bruising, swelling, local inflammation, and rare infection.

Frequently Asked Question

Is the P Shot the same as PRP?

In most UK clinics, yes — the P Shot is a type of PRP (Platelet-Rich Plasma) injection. It uses your own blood to extract plasma rich in growth factors, which is then injected into the penis. While PRP is used in many areas of medicine, the P Shot is a specific application for sexual health.

Does the P Shot treat erectile dysfunction (ED)?

Some men report mild improvement in erectile function after the P Shot, but medical guidelines remain cautious. The European Association of Urology (EAU) and the Sexual Medicine Society of North America (SMSNA) note that evidence is still limited and mostly anecdotal.

Does it increase size?

Claims about increased penis size after the P Shot are not backed by strong clinical evidence. While some men report changes in girth or sensitivity, these results vary and are not guaranteed.

Is it the same as PRP?
Yes — the P Shot is a form of PRP therapy. It involves drawing a small amount of your blood, processing it to concentrate the platelets, and injecting it into the penis. The goal is to stimulate tissue regeneration and improve blood flow.

How long does it take to see results?
Most men begin to notice changes within 2 to 6 weeks after the injection. Improvements in sensitivity, firmness, and performance may continue over several months. Results vary depending on age, health, and lifestyle.

Is it available in the UK?
Yes — the P Shot is available in private clinics across the UK, including Harley Street in London. It’s not currently offered by the NHS, but many reputable clinics provide the treatment with full discretion and medical oversight.

Who should avoid it?
Men with bleeding disorders, active infections, or certain chronic illnesses may not be suitable candidates. It’s also not recommended for those with unrealistic expectations or untreated psychological causes of ED. Always consult a qualified doctor before considering the P Shot.
