What Is Shockwave Therapy (ESWT)? Its Efficacy in Erectile Dysfunction
ESWT (Extracorporeal Shock Wave Therapy) is a non-invasive treatment method that creates a biological response by transmitting low-intensity acoustic waves to target tissue. ESWT, which has been used in orthopedics and physical therapy for decades, has come to the forefront in erectile dysfunction (ED) treatment over the last 15 years with an increasingly growing evidence base.
What Is ESWT? How Does It Work?
Shock waves are high-pressure, short-duration acoustic impulses. Low-intensity ESWT used in ED treatment (Low-intensity ESWT — LiESWT):
Mechanisms of Action
| Mechanism | Explanation |
|---|---|
| Neovascularization | VEGF is released with mechanical stimulation → new vessel formation |
| Endothelial eNOS activation | Nitric oxide (NO) increase → vasodilation |
| Growth factor release | PDGF, TGF-β, IGF-1 → tissue repair |
| Neurotrophic effect | NGF → cavernous nerve regeneration |
| Fibrolysis | Collagen breakdown in Peyronie plaques |
| Stem cell activation | Resident endothelial progenitor cells stimulated |
Difference from High-Intensity ESWT
| Feature | High-Intensity ESWT | Low-Intensity ESWT (LiESWT) |
|---|---|---|
| Area of use | Kidney/gallstone breaking | ED, Peyronie, chronic pelvic pain |
| Energy | High (>0.2 mJ/mm²) | Low (<0.1 mJ/mm²) |
| Effect | Mechanical fragmentation | Biostimulation, regeneration |
| Pain | Significant | Minimal or none |
ESWT’s Role in Erectile Dysfunction
Indications
| Condition | ESWT’s Role |
|---|---|
| Vascular ED | First-line non-invasive treatment; strong evidence |
| ED non-responsive to PDE5 inhibitors | Response enhancer (resensitization) |
| Peyronie’s disease | Plaque softening + curvature reduction |
| Post-prostatectomy ED | Cavernous nerve rehabilitation |
| Diabetic ED | Neurovascular healing support |
| Chronic pelvic pain / prostatitis | Symptom reduction |
Contraindications
- Active genital infection or open wound
- Bleeding disorder or active anticoagulant treatment
- Presence of penile implant (prosthesis)
- Active cancer treatment
- Pregnancy (for application on surrounding tissues)
- Pacemaker: Low risk for direct cavernous injection; however, caution required
Scientific Evidence: ESWT’s Efficacy in ED
Randomized Controlled Studies
| Study | Patients | Result |
|---|---|---|
| Vardi et al. (2012) | 67 vascular ED | Average +7.2 points in IIEF; superior to placebo |
| Gruenwald et al. (2013) | 29 ED non-responsive to PDE5 inhibitors | Spontaneous erection returned in 72% of patients |
| Kitrey et al. (2016) | 58 mild-moderate ED | Significant improvement continued in 57% of patients at 12-month follow-up |
| Behr-Roussel et al. (2020) | Meta-analysis, 7 RCTs | Average +5.7 point increase in IIEF |
| Fojecki et al. (2017) | Moderate-severe vascular ED | Synergistic effect in PDE5 inhibitor combination |
2024 Cochrane Review
A Cochrane review covering 7 randomized studies reported that LiESWT provided statistically significant IIEF improvement in the short-to-medium term (6–12 months) in vascular ED; more data is needed for long-term effect.
Evidence Level Assessment
| Parameter | Assessment |
|---|---|
| General evidence level | Level Ib–IIa |
| EAU Guideline (2024) | Recommendable in vascular ED (Grade B) |
| AUA (US) guideline | Applicable in research context |
| Most effective area | Mild-moderate vascular ED |
| Least effective area | Psychological ED, severe neurogenic ED |
ESWT Protocol: How Many Sessions, How Is It Applied?
Standard Protocol
| Parameter | Value |
|---|---|
| Number of sessions | 6–12 sessions |
| Session frequency | 1–2 times per week |
| Total duration | 3–6 weeks |
| Waves per session | 2,000–3,000 impulses |
| Energy density | 0.05–0.25 mJ/mm² |
| Application area | Penile dorsal + lateral + proximal |
Application Process
- Preparation: Positioning the patient in standing or lying position
- Gel application: Ultrasound gel (for transmission)
- Probe positioning: Along the penile length at 5 areas
- Wave application: Equal distribution to each area
- Session duration: 15–20 minutes
- Patient experience: Mild vibration sensation; generally no pain
Comparison of ESWT with Other Treatments
| Treatment | Mechanism | Onset of Effect | Permanence | Cost | Evidence |
|---|---|---|---|---|---|
| PDE5i | Instant NO increase | Minutes | Instant | Low | Highest |
| LiESWT | Angiogenesis + regeneration | 4–12 weeks | 12–24 months | Moderate | High |
| P-Shot | Growth factor | 4–12 weeks | 12–18 months | Moderate-high | Moderate |
| SVF | Cellular regeneration | 4–16 weeks | 1–3 years | High | Moderate-low |
| Vacuum | Mechanical blood draw | Instant | Instant | Low | Moderate |
| Prosthesis | Mechanical support | Permanent | Permanent | Very high | High |
ESWT + P-Shot Combined Treatment
ESWT and P-Shot strongly complement each other:
- ESWT first: Shock waves “prepare” the tissue — local inflammatory environment and growth factor receptors are activated
- P-Shot immediately after: Exogenous growth factors are delivered to the prepared environment → synergistic effect
In a 2022 study, ESWT + PRP combination provided 35% higher IIEF improvement compared to ESWT alone.
ESWT Device Types
| Device Type | Wave Source | Feature |
|---|---|---|
| Electromagnetic | Electromagnetic field | Most common; consistent wave production |
| Electrohydraulic | Underwater electrical | Powerful; more invasive |
| Piezoelectric | Piezoelectric crystals | Precise focusing |
| Radial | Air pressure (balloon) | Superficial; unfocused — less preferred for ED |
Focused vs. Radial ESWT: Focused ESWT efficiently delivers energy to deep penile tissues. Radial wave devices have more superficial effects; the vast majority of ED research has been conducted with focused systems.
Side Effects
ESWT is generally very well tolerated:
| Side Effect | Frequency | Duration |
|---|---|---|
| Mild pain/discomfort | 10–20% | During or briefly after session |
| Temporary redness | Rare | 24–48 hours |
| Hematoma | Very rare | Resolves spontaneously |
| Erectile worsening | Very rare (temporary) | 1–2 weeks |
No serious side effects have been reported.

ESWT in Peyronie’s Disease
ESWT for Peyronie’s disease (penile curvature + plaque formation):
- Active phase (<12 months): Pain reduction + plaque softening
- Stable phase (>12 months): Curvature correction is limited; collagenase or surgery is more effective
- Combination: Collagenase + ESWT + penile traction device gives the best results
Frequently Asked Questions
Is ESWT painful? Low-intensity ESWT is tolerated by most patients without pain or with minimal discomfort. A mild vibration sensation is normal.
In how many sessions does ESWT show its effect? The effect generally begins within 4–8 weeks. Maximum effect can be evaluated at months 3–6.
Is ESWT permanent? It shows good effect in the short-to-medium term (12–24 months). Repetition of ESWT or use of PDE5 inhibitors may be recommended for long-term effect.
Can ESWT be applied while using sildenafil/tadalafil? Yes. Continuing PDE5 inhibitor use alongside ESWT is recommended; combined use produced better results in some protocols.
Who is ESWT not suitable for? Active genital infection, bleeding disorder, penile prosthesis, active cancer treatment.
At what age can ESWT be performed? No age limit. Effective use has been reported in patients aged 30–80.
When can sexual activity be resumed after ESWT? No restriction on the day of the session; most patients can continue their activity the same day.
Are ESWT devices reliable in Turkey? European-manufactured medical-grade devices (BTL, Storz, Dornier) are reliable and widely used in major clinics in Turkey.
