Overview
What Is the P-Shot (Priapus Shot)?
The P-Shot, also called the Priapus Shot, is a men's sexual-wellness procedure that uses platelet-rich plasma (PRP) drawn from a patient's own blood. Named after the Greek fertility figure Priapus, it has become one of the more discussed options in regenerative men's health.
The concept is straightforward. A small blood draw is processed to concentrate its platelets, and that PRP is then injected into specific areas of the penis. Platelets carry growth factors that the body naturally uses in tissue repair and healing.
This guide is educational and not medical advice. At Protocol Health in Scarsdale, NY, the P-Shot is considered only after a physician-led evaluation, because whether it is appropriate depends on your health history, goals, and often lab work.

What does the P-Shot do?
The P-Shot involves injecting your own concentrated platelets into penile tissue with the aim of supporting blood flow, tissue health, and sexual function. Because PRP uses your own blood, allergic reactions are uncommon and downtime is typically minimal.
It is generally explored by men interested in supporting erectile quality, sensitivity, or overall sexual wellness. Responses vary from person to person, and it is not a guaranteed fix or a substitute for treating underlying medical causes. A qualified physician determines whether it may be appropriate for you.
The Science
How does the P-Shot work?
The P-Shot works by concentrating platelets from your own blood into platelet-rich plasma and injecting it into the penis, where its growth factors may support tissue repair. The procedure begins with a simple blood draw, similar to routine lab work. That blood is placed in a centrifuge, which separates and concentrates the platelets into platelet-rich plasma.
Platelets are rich in growth factors, the signaling proteins the body uses in wound healing and tissue maintenance. The idea behind PRP procedures is that delivering these concentrated factors to a target area may support the body's own regenerative and vascular processes.
For comfort, the treatment area is numbed before the PRP is injected into predetermined locations. The appointment is usually brief, and because the material comes from your own body, it avoids the compatibility concerns of a foreign substance.
PRP for sexual wellness is considered an off-label, elective use. The evidence base is still developing, which is exactly why individualized, physician-supervised care matters.
The Upside
What are the potential benefits of the P-Shot?
Men explore the P-Shot for a range of reasons: interest in firmer or more reliable erections, improved sensitivity, and general sexual confidence. Some also consider it as part of a broader men's health plan alongside hormone or lifestyle optimization.
Research on PRP for sexual function is still emerging, and outcomes differ between individuals. In many cases it is viewed as a complement to, rather than a replacement for, addressing root causes such as hormonal imbalance, cardiovascular health, or medication effects.
The randomized evidence on the Priapus Shot points in both directions. A 2024 meta-analysis of four randomized trials covering 413 men found PRP improved erectile-function scores more than placebo at one, three and six months. A 2023 double-blind, placebo-controlled trial at the University of Miami gave 61 men with mild to moderate erectile dysfunction two injections a month apart and found PRP safe, but no difference in efficacy between PRP and placebo. That is why Protocol Health presents the P-Shot as an option worth discussing, not a promised result.
Because sexual health is often multifactorial, the P-Shot may work best as one piece of a comprehensive, lab-informed strategy rather than a standalone answer.
Candidacy
Who is a candidate for the P-Shot?
A candidate for the P-Shot is generally a healthy adult man who wants to support sexual wellness and prefers a regenerative, autologous (own-blood) approach. It may appeal to men who have not fully responded to first-line options or who want to combine therapies.
Candidacy is always determined case-by-case by a physician. Your provider will review your medical history, medications, and often blood work, and will screen for conditions that could make the procedure inappropriate or that deserve treatment first.
Sexual concerns can signal underlying issues worth evaluating, from hormone levels to vascular health. That is why we frame the P-Shot within a full assessment rather than treating it in isolation. Related evaluation may include our male hormone and longevity workups.
Safety
Is the P-Shot safe? Side effects to know
The main safety point for the P-Shot is that it uses your own platelets, and its side effects to know are mostly mild and temporary. Because the P-Shot uses your own platelets, the risk of allergic or rejection reactions is low. The area is numbed beforehand, and most men tolerate the procedure well with minimal downtime.
As with any injection, temporary side effects can include mild swelling, bruising, tenderness, or redness at the injection sites, which typically resolve on their own. Your provider will review specific risks, aftercare, and any activity guidance with you.
Some men are not suitable candidates, including those with a bleeding disorder, certain blood conditions, an active infection, or specific medications. This is educational information, not medical advice; a qualified provider must evaluate your individual situation before any treatment.
The Experience
What to expect during and after a P-Shot
During and after a P-Shot, expect a visit of under an hour and a quick return to normal activities. A typical visit starts with a consultation and, when indicated, lab work, followed by the blood draw and PRP preparation. Numbing is applied, the injections are performed, and the appointment is usually completed in under an hour.
Most men return to normal daily activities quickly, following any personalized aftercare instructions from the clinical team. Because PRP works with the body's own healing timeline, any changes tend to develop gradually over the following weeks rather than instantly.
Your provider may discuss whether a series of treatments or pairing with other therapies fits your goals, and will set realistic, individualized expectations from the start.

The Priapus Shot injects PRP from a man's own blood into penile tissue with the aim of supporting erectile function. It is off-label, not FDA-approved, and the randomized evidence is mixed, so at Protocol Health it is considered only after a physician-led evaluation.
FAQ
Frequently Asked Questions
How long does it take to see results from the P-Shot?
Because PRP works with the body's natural healing processes, any changes typically develop gradually over several weeks rather than immediately. Individual responses vary, and your provider will set realistic, personalized expectations. Some men consider a series of treatments as part of their plan.
Is the P-Shot painful?
The treatment area is numbed before the injections, so most men tolerate the procedure well. Some may notice mild, temporary tenderness, swelling, or bruising afterward that usually resolves on its own. Your provider will review comfort measures and aftercare with you.
How is the P-Shot different from ED medications?
Oral medications like sildenafil or tadalafil work on demand by supporting blood flow around the time of intimacy. The P-Shot is a regenerative approach using your own platelets and is sometimes explored alongside, rather than instead of, other therapies. A physician can help you weigh the options for your situation.
Do I need lab work before a P-Shot?
Often, yes. Sexual concerns can be linked to hormone levels, cardiovascular health, or other factors, so a physician-led evaluation and appropriate labs help determine whether the P-Shot is suitable and whether any underlying issues should be addressed first. Candidacy is always determined case-by-case.
Is the P-Shot FDA-approved?
No. The P-Shot is not an FDA-approved treatment for erectile dysfunction or any sexual-health condition. PRP is prepared from your own blood with devices cleared for other uses, so injecting it into the penis is an off-label, elective procedure, and the trial evidence is mixed. It should always be performed under qualified medical supervision after an individualized evaluation. This information is educational and not a substitute for professional medical advice.
Can the P-Shot be combined with other treatments?
Many men explore the P-Shot as one part of a broader men's health plan that may include hormone optimization, shockwave therapy, or lifestyle changes. Because sexual health is often multifactorial, a lab-informed evaluation helps decide which pieces belong in the plan. Your provider will tailor any combination to your goals.
