Low-Intensity Shockwave Therapy (Li-SWT) for ED: Regenerative Treatment & Clinical Evidence
What is shockwave therapy for erectile dysfunction?
Li-SWT is a non-invasive, regenerative ED treatment that aims to restore natural erectile function by stimulating new blood vessel growth.
Shockwave therapy can be an effective form of treatment for erectile dysfunction and it is currently available at Pantai Hospital Penang. You may consult Dr. William Ong, Pantai Hospital Penang to find out more about the procedure and its package.
Who is the best candidate?
Li-ESWT is best suited for men with vasculogenic ED – the most common type, often due to:
Atherosclerosis (hardening of arteries)
Diabetes mellitus
Hypertension
high cholesterol
Post-radical prostatectomy (nerve-sparing)
Poor response to or desire to avoid PDE5 inhibitors
Treatment protocol
Our protocol aligns with evidence-based standards (including published study):
Sessions: 6–12 sessions (typically once weekly for 6 weeks)
Duration per session: 15–20 minutes
Application sites: Three areas along the corpora cavernosa – base, shaft, and crux
Anesthesia: None required – the procedure is painless; mild discomfort can be managed by adjusting intensity
Recovery: You can return to normal activities immediately
Most men begin noticing improved erectile hardness and spontaneity after 2-4 sessions. Full benefit may be seen several weeks after completing the series.
Local published data
Dr William Ong et al. published clinical study in a respected andrology journal (Andrologia, DOI: 10.1111/and.14518).
In this study, low‑intensity shockwave therapy was tested on men with mild‑to‑moderate ED caused by poor blood flow.
After completing the full treatment course, most men reported firmer erections and better sexual function. These improvements lasted for many months without the need for daily pills or injections. The treatment was very safe – no serious side effects occurred.
In conclusion, low‑intensity shockwave therapy can be confidently offered as non‑invasive option for suitable men who want to treat the root cause of ED, not just the symptoms.
Other uses:
Beyond ED, low-intensity shockwave therapy can also be used for:
Peyronie’s disease – to reduce plaque size and pain (different protocol)
Chronic pelvic pain syndrome (CPPS) – to improve microcirculation and reduce pain
These applications require separate evaluation and treatment planning.

Frequently Asked Questions (FAQs)
Is shockwave therapy better than Viagra?
They work differently. PDE5 inhibitors improve erection during sexual stimulation, while LiSWT aims to improve the underlying penile vascular function.
Is shockwave therapy painful?
No. Most patients describe mild tapping sensation without significant pain.
How many sessions are required?
Treatment protocols vary. Many clinical studies use several sessions over several weeks.
Does shockwave therapy permanently cure ED?
No treatment guarantees a permanent cure. LiSWT aims to improve penile blood flow and erectile function in selected patients.
