P-Shocks vs P-Shot for ED and Peyronie’s: Evidence by Condition

P-Shot and P-Shocks are marketed for both erectile dysfunction and Peyronie’s disease, but the two conditions have different treatment goals and different evidence. For ED the outcome is erection quality; for Peyronie’s disease the key outcomes are pain, curvature, deformity, length and intercourse function.
Neither a PRP injection nor a combined P-Shocks pathway should be presented as one proven solution for two different diagnoses.
What is the difference between P-Shot and P-Shocks?
A P-Shot usually means penile platelet-rich plasma injection. P-Shocks is the clinic’s name for a broader pathway that may include assessment, low-intensity shockwave therapy, PRP, a vacuum erection device, lifestyle or cardiovascular risk management and established ED treatment.
P-Shocks is not a universally standardised procedure, so the exact components should be stated before consent. More components do not automatically mean better results.

Different conditions require different outcomes
Erectile dysfunction
Primary outcome: the ability to achieve and maintain an erection.
Assessment: vascular, metabolic, hormonal, medication-related, neurological and psychological contributors.
Established options: lifestyle and cardiovascular treatment, PDE5 inhibitor tablets, psychosexual support, vacuum devices, injection therapy and surgery.
Newer option: low-intensity shockwave therapy for selected vasculogenic ED, with modest and variable benefit.
Investigational option: PRP, for which evidence remains insufficient for routine use.
Peyronie’s disease
Primary outcomes: pain, measured curvature, indentation or hourglass deformity, length, stability and intercourse function.
Assessment: active versus stable phase, plaque, erection quality and progression.
Conservative options: observation, traction in selected patients and treatment of associated ED.
Intralesional treatment: suitable agents may offer partial curvature improvement where available.
Surgery: considered for stable deformity that prevents satisfactory intercourse.
What does the evidence show for ED?
Shockwave therapy
European guidance gives low-intensity shockwave therapy a weak recommendation for selected men with vasculogenic ED. Studies suggest a mild average improvement, but device protocols differ and some patients do not respond.
PRP and the P-Shot
PRP studies are small and heterogeneous. They do not establish an ideal preparation, dose, injection schedule or durable benefit. European guidance advises PRP for ED only in a clinical-trial setting.
Combined treatment
There is no reliable evidence that PRP and shockwave therapy create a synergistic effect when combined. Each component should be justified separately against established care.

What does the evidence show for Peyronie’s disease?
Shockwave therapy
Shockwave may reduce penile pain in selected patients, particularly during the active phase. It is not recommended to improve curvature or reduce plaque because reliable straightening has not been shown.
PRP
PRP evidence for Peyronie’s disease remains preliminary. Current studies do not establish dependable improvement in curvature, plaque, length or erection quality.
Vacuum and traction devices
Traction may help preserve length or modestly reduce curvature in selected patients who can follow a structured protocol. A vacuum device can support erections but evidence for straightening is limited. Incorrect use can cause bruising or injury.
Why diagnosis matters before any regenerative treatment
A man with vasculogenic ED, a man with performance anxiety and a man with a stable 60-degree Peyronie’s curvature do not have the same problem. Offering one package before diagnosis risks delaying appropriate treatment and makes informed consent impossible.
Confirm the principal diagnosis and treatment goal.
Document ED severity or penile deformity before treatment.
Discuss established options and no-treatment choices.
Explain which components are investigational.
Agree how outcome and adverse effects will be reviewed.
Frequently asked questions
Is P-Shocks better than P-Shot for ED?
That has not been established. A broader assessment can improve decision-making, but the combined procedure itself has not been proven superior.
Can either option straighten Peyronie’s curvature?
Reliable straightening from PRP or shockwave therapy has not been shown. Shockwave may help pain; deformity-focused options should be discussed separately.
Can P-Shot or P-Shocks restore penile length?
Reliable anatomical enlargement or restoration of lost length has not been established. Traction may be considered for length preservation or modest change in selected Peyronie’s patients.
Which treatment should be tried first?
The correct sequence depends on the diagnosis. Established ED or Peyronie’s options should be considered before investigational procedures.

Medical review and evidence
Medically reviewed by Dr Fabio Castiglione, Consultant Urologist and Andrologist. Last reviewed: 19 August 2026.
For ED, shockwave therapy has a weak recommendation for selected vasculogenic cases and PRP remains investigational. For Peyronie’s disease, shockwave may help pain but not curvature or plaque; PRP evidence remains preliminary.
