Treatment comparison
P-Shot vs shockwave therapy: what's the difference, and which is right for you?
The P-Shot and focused shockwave therapy are both regenerative treatments for erectile dysfunction, but they work through different mechanisms. The P-Shot injects concentrated growth factors directly into the penile tissue. Focused shockwave uses acoustic waves to stimulate new blood vessel formation. They are most effective when combined, which is why we offer a same-day Enhanced protocol. Standalone P-Shot suits sensitivity loss and Peyronie's disease; standalone shockwave suits pure vasculogenic ED; the combination suits multifactorial cases.
The summary table
| Detail | P-Shot (PRP) | Focused shockwave (LI-ESWT) | Combined / Enhanced protocol |
|---|---|---|---|
| Mechanism | Concentrated growth factors injected into tissue | Acoustic waves stimulate angiogenesis in situ | Both, sequenced in one appointment |
| What's delivered | Your own platelets and growth factors | Mechanical energy (no substance injected) | Both |
| Best for | Mild-to-moderate ED, Peyronie's, sensitivity loss, post-prostate rehab | Pure vasculogenic ED, diabetic ED, age-related vascular decline | Multifactorial ED, sub-optimal PDE5 response, diabetic ED, post-prostate |
| Anaesthetic | Topical or nerve block | None usually needed | Topical for the PRP component |
| Discomfort level | Mild pressure | Firm tapping | Combined, as above |
| Number of visits | 1 (standard) | 6-12 (standalone course) | 1 (same-day Enhanced) |
| Time to first improvement | 4-6 weeks | 2-4 weeks | 2-4 weeks |
| Peak results | 8-12 weeks | 8-12 weeks | 8-12 weeks |
| Duration of result | 12-18 months | 12-24 months | 12-24 months |
| Cost | £1,250 | from £500/session (course typically £2,500) | £1,350 |
| Performed by your doctor | Yes | Yes | Yes |
How PRP works
Platelet-rich plasma is your own blood, processed in a centrifuge to concentrate the platelets. Platelets carry growth factors: proteins your body uses for healing. Injected directly into the penile shaft and corpora cavernosa, these growth factors stimulate:
- Angiogenesis (new blood vessels)
- Neurogenesis (nerve fibre regeneration)
- Collagen and elastin remodelling
- Anti-inflammatory effects
The treatment doesn't "do" something to the tissue mechanically. It signals the body to do regenerative work itself, by delivering the chemical signals at high concentration to the right anatomical sites.
How focused shockwave works
Focused low-intensity extracorporeal shockwave therapy (LI-ESWT) uses precisely-calibrated acoustic waves to create controlled mechanical stress in the erectile tissue. This micro-mechanical signal triggers the body's own growth-factor cascade, particularly vascular endothelial growth factor (VEGF) and endothelial nitric oxide synthase (eNOS), which drives angiogenesis.
Where PRP delivers growth factors directly, shockwave triggers your body to produce them in situ. The end result is similar, with more blood vessels, better blood flow, and better erections. The biology is complementary.
When to choose PRP alone
The Standard P-Shot is the right choice when:
- The picture is primarily tissue rather than purely vascular
- Sensitivity loss is a major component
- Peyronie's disease is present (PRP for plaque modulation)
- You're in post-prostate rehabilitation and nerve regeneration is the priority
- You prefer one-and-done over a course of multiple visits
- Your case is mild-to-moderate and one treatment is likely sufficient
When to choose shockwave alone
Standalone focused shockwave is the right choice when:
- PRP is contraindicated (platelet disorders, certain coagulation issues, specific cancers)
- Your case is purely vasculogenic with no tissue or sensitivity component
- You specifically prefer a course of multiple shorter visits over a single longer appointment
- You're working within a specific budget that suits per-session pricing
When to combine them
The Enhanced (same-day combined) protocol is the right choice when:
- Your ED is multifactorial, with vascular and tissue components
- You have diabetes-related ED
- You have sub-optimal response to PDE5 inhibitors
- You're 55+ with age-related multifactorial decline
- You have Peyronie's disease alongside ED
- You want both regenerative pathways activated in one visit
The Enhanced protocol may be considered where erectile dysfunction is multifactorial and vascular factors are part of the clinical picture. Suitability is confirmed at consultation.
Can shockwave alone replace the P-Shot?
For pure vasculogenic ED, often yes. The literature for LI-ESWT in vasculogenic ED is the stronger of the two, and a six-session course can achieve excellent results without injection. For mixed or tissue-component ED, shockwave alone leaves part of the picture untreated.
Can the P-Shot alone replace shockwave?
For mild-to-moderate ED with strong tissue/sensitivity components, often yes. For severe vasculogenic ED, particularly diabetic and age-related vascular decline, the P-Shot alone is less likely to be sufficient than the combination.
FAQ
Which has the stronger evidence base? Focused shockwave (LI-ESWT) for ED has a longer and broader evidence base, and is referenced in European Association of Urology guidance. PRP for ED has growing evidence, with the Poulios et al. (2021) trial being the most-cited reference. Combination protocols have less mature evidence but a consistent positive signal.
Which one is cheaper overall? The P-Shot at £1,250 is cheaper than a six-session shockwave course (~£2,500). The Enhanced protocol at £1,350 is cheaper than booking both treatments separately.
Which one is more painful? Neither is significantly painful. The shockwave feels like firm tapping; the PRP injections feel like pressure after numbing. Most patients find them comparable.
Which one is faster acting? Shockwave tends to produce noticeable change a couple of weeks earlier than PRP alone, but both peak at 8-12 weeks.
Should I do PRP first or shockwave first if I'm doing them separately? If you're doing them on different days, shockwave first, then PRP. The shockwave-primed tissue absorbs PRP better. But the Enhanced same-day protocol gets both effects in a single visit and is what we'd usually recommend.
