Two devices, one word
The word 'shockwave' covers two fundamentally different machines in clinical practice. The distinction matters because the evidence base for ED treatment is on one of them, not the other.
Focused shockwave (Li-ESWT, focused low-intensity extracorporeal shockwave therapy) uses a piezoelectric or electromagnetic generator that produces an acoustic wave which converges at a precise focal point inside tissue. The device is engineered so that the energy intensity peaks at a designated depth — typically 30 to 50 millimeters for ED applications — and falls off rapidly above and below that depth. This means the treatment can deliver therapeutic energy specifically to the corpora cavernosa (the erectile tissue) without high-energy delivery to the skin surface above it.
Radial shockwave (rESWT, radial extracorporeal shockwave therapy) is mechanically different. A pneumatically-driven projectile strikes an applicator at the skin surface, producing a pressure wave that disperses radially as it enters the tissue. Energy is highest at the skin contact point and decreases continuously with depth. Radial devices were designed for and validated on superficial musculoskeletal targets — calcific tendinitis of the rotator cuff, plantar fasciitis, lateral epicondylitis — where the target is just below the skin.
Both machines are sometimes marketed as 'shockwave therapy.' Both produce a wave. They are not equivalent for any indication that requires deep, focused energy delivery.
Why this matters for ED specifically
The corpora cavernosa — the spongy erectile tissue that fills with blood to produce an erection — sits roughly 20 to 40 millimeters beneath the skin surface depending on the man's anatomy. The vascular endothelial cells whose regeneration is the mechanism of Li-ESWT live in that deep tissue.
A focused device can deliver therapeutic acoustic energy to that depth without overdosing the skin. A radial device cannot — its energy peaks at the surface and is substantially attenuated by the time it reaches the depth where erectile tissue lives. The result is that radial protocols for ED tend to deliver superficial energy without the deep tissue dose the focused trial protocols use.
This is not a subtle distinction. It is the entire reason every published Li-ESWT meta-analysis and every position statement from the European Society of Sexual Medicine and European Association of Urology refers specifically to focused devices.
What the evidence base actually says
Key features of the published evidence on shockwave therapy for ED:
- The foundational RCTs (Vardi et al., Olsen et al., Kitrey et al.) were conducted with focused low-intensity devices.
- The Sokolakis & Hatzichristodoulou systematic review (the most-cited meta-analysis as of recent years) explicitly notes that the response rates reported in the literature are derived from focused-device studies; radial protocols are categorised separately and show smaller or non-significant effects in many of the cited studies.
- The European Society of Sexual Medicine 2019 clinical recommendations differentiate focused and radial protocols and assign different evidence levels to each.
- The European Association of Urology guidelines reference focused devices when discussing Li-ESWT as a treatment option for vasculogenic ED.
How to tell which a clinic uses
The simplest test is to ask directly: 'Is the device focused or radial? What's the brand and model?' A clinic using a real focused system will name it — common focused devices include Storz Duolith SD1, Direx Renova, MTS Urogold 100, BTL-6000 (focused module), Richard Wolf Piezowave2. A clinic using radial equipment will often name a different brand — Storz Masterpuls, Chattanooga Intelect, BTL-6000 (radial module). Some clinics own both and use the appropriate device per indication; that's also fine, but they should tell you which one is being used for your treatment.
Signs you may be looking at radial-only shockwave being marketed for ED:
- Per-session price meaningfully below the focused-device market range (e.g., under ₱4,000/session in Manila as of 2026).
- The clinic primarily offers musculoskeletal pain treatments and ED is one item on a longer menu.
- When asked about the device, the answer is vague or simply 'shockwave therapy' without a brand or model.
- The session is unusually short (under 10 minutes of treatment time) — focused protocols typically take 15–20 minutes per session.
- The marketing emphasises sensation ('you'll feel it working') rather than the underlying biology.
Is radial useless for ED? Honest read
We don't want to overstate the case. Some studies have reported modest effects from radial protocols for ED, especially in milder cases. The published evidence supporting radial for ED is not zero — it is just substantially weaker than for focused devices, and the effect sizes are smaller. If a patient genuinely cannot access a focused-device clinic (geographically or financially), a radial protocol may be a reasonable starting point with the understanding that the realistic expectation is lower.
What we caution against is paying premium focused-device prices for radial-device treatment under the marketing of 'shockwave therapy for ED.' That is the most common pricing inconsistency we see in the Manila men's-health market. A reputable clinic will tell you which device they use and price accordingly.
What we use at Hummingbirds
Hummingbirds for Homme uses a focused low-intensity shockwave device specifically calibrated for ED treatment protocols. We're happy to discuss the specific device and energy-flux-density parameters at consultation. Our standard ED protocol is 6–8 sessions of focused treatment over 3–4 weeks, billed per session at ₱5,000, with IIEF-5 reassessment at session 4–5.
