Does Shockwave Therapy Work for Erectile Dysfunction?
Shockwave therapy can help some men with erectile dysfunction, mainly when mild ED comes from reduced blood flow. However, the benefit in trials is modest and varies widely. It rarely helps severe ED or ED after nerve damage, so a proper assessment should come first.

Clinic adverts often describe shockwave therapy as a cure. In contrast, research papers describe a smaller and less certain effect. This guide explains what the evidence shows, who tends to benefit and what to expect.
What is shockwave therapy for ED?
Low-intensity shockwave therapy, often shortened to Li-ESWT, sends short pulses of acoustic energy into the penis. A handheld probe touches the shaft and the area near its base. Its energy level sits far below the level that breaks kidney stones.
The aim is better blood supply: in laboratory studies, the pulses seem to trigger new small blood vessels. They may also support repair of the erectile tissue. As a result, the penis may fill with blood more easily during arousal.
Because of this mechanism, shockwave therapy targets one cause of ED in particular. That cause is vasculogenic ED, which means weak blood flow into the erectile tissue. Other causes, such as nerve injury or low testosterone, do not respond in the same way.
Focused shockwaves and radial pressure waves
Not every machine sold as "shockwave" works the same way. Focused and linear devices concentrate energy at a set depth. Radial devices, which many home and gym products use, spread pressure waves near the skin instead.
Most clinical trials used focused or linear machines. Therefore, results from those studies do not automatically apply to radial devices or home products. Before you pay for a course, ask which type of device the clinic uses.
What does the evidence say?
The honest answer is that it depends; for example, a 2025 Cochrane review pooled 21 trials against a sham procedure. It found a small short-term gain, often too small to notice. It also suggested a possible longer-term benefit.
Side effects in those trials were uncommon. Still, the authors rated their confidence in the results as limited. Also, studies used different machines, settings and session counts, which makes direct comparison difficult.
Public health sources reflect this caution; for example, the NHS page on erection problems covers tablets, vacuum pumps and treating the cause, and NIDDK adds injections and implants. Yet neither includes shockwave therapy. Meanwhile, the American Urological Association still describes it as investigational.
European guidance is more open, as the European Association of Urology allows it for selected men with mild vasculogenic ED. However, those men should first understand the limits of the evidence. In short, specialists accept that it can help, but only in the right patient.
Why success rates vary so much
You will see success rates quoted on clinic websites, and they often differ widely. That spread has several causes. First, studies define success in different ways, from a few points on a questionnaire to full restoration of erections.
Second, the men in each study differ. Healthy men in their forties with mild ED respond differently from men with long-standing diabetes. Finally, short follow-up can make results look better than they turn out to be later.
For these reasons, a single percentage tells you little about your own chances. Your likely response depends far more on the cause and severity of your ED than on any headline figure.
Who is most likely to benefit
Shockwave therapy tends to suit men whose erections have weakened gradually, but who still get some firmness. In these men, blood flow has dropped, but the tissue can still respond. Typical examples include the following.
Men with mild ED linked to reduced blood flow.
Men who respond partly to tablets and want a better response.
Men who prefer not to rely on medicine before every sexual encounter.
Men with early vascular risk factors, such as smoking or raised cholesterol, who are also changing their lifestyle.
Younger men often ask about it too. However, ED under 30 often has other causes. So the assessment in young men checks stress, hormones and anatomy first.
Who is unlikely to benefit
Shockwave therapy has clear limits. It cannot rebuild nerves, replace hormones or fix scar tissue. As a result, the following groups usually gain little from it.
Men with severe ED who get no useful firmness, even with tablets.
Men with nerve damage after radical prostate surgery or pelvic radiotherapy.
Men whose ED comes mainly from anxiety, depression or relationship strain.
Men with low testosterone that has not been treated.
Men with venous leak, where blood flows into the penis but drains away too quickly.
Venous leak deserves a special mention. It needs a penile Doppler ultrasound to confirm, and it rarely improves with shockwaves. Similarly, men recovering from prostate cancer surgery usually do better with a structured penile rehabilitation plan.
How shockwave therapy compares with other ED treatments
Shockwave therapy is one option among several. The table below compares the main treatments that a urologist may discuss with you.
Treatment | How it works | Best suited to | Main limitation |
Shockwave therapy | Aims to improve blood supply to the erectile tissue | Mild ED caused by reduced blood flow | Modest, variable effect that may fade |
Tablets (tadalafil, sildenafil) | Boost the natural erection response | Most men with mild to moderate ED | Must be taken before sex or daily |
Penile injections | Relax the erectile tissue directly | Men who do not respond to tablets | Needle use before each encounter |
Vacuum device | Draws blood into the penis with suction | Men who cannot use medicine | Can feel cold or less natural |
Penile implant | A device inside the penis creates an erection | Severe ED when other options fail | Surgery, and natural erections rarely return |
These options are not mutually exclusive. For instance, many men use shockwave therapy alongside tablets. If tablets have stopped working for you, read why tadalafil and sildenafil can stop working before you choose a new path.
What to expect from a course of treatment
A typical course involves several short sessions over a few weeks. Each session usually lasts about 15 to 20 minutes, and you can return to normal activities straight afterwards. Protocols differ between devices, so your clinic should explain its own plan.
Results do not appear overnight. Instead, any improvement tends to build gradually over the weeks after the final session. Most specialists judge the response after one to three months.
The benefit, when it comes, is often partial. For example, a man may notice firmer erections, better response to tablets or a lower dose need. Fewer men find that they no longer need any medicine.
How long do the results last?
Long-term data remains scarce. In men who respond, the benefit often lasts several months and sometimes longer. However, shockwave therapy does not stop the processes that caused ED in the first place.
Therefore, controlling blood sugar, blood pressure and cholesterol matters as much as the treatment itself. Stopping smoking and staying active also help protect the result. Some men choose a repeat course when the effect fades.
Side effects and safety
Most men tolerate shockwave therapy well. They usually describe a tapping sensation or mild discomfort, and they need no anaesthetic. Occasionally, small bruises or brief soreness appear and then settle within days.
Even so, a doctor should check you first, because blood-thinning medicine, a bleeding disorder or an active infection in the area may change the plan. In addition, ED can signal early heart disease. So a health check should always come before treatment.
Shockwave therapy for Peyronie's disease is a different use
Doctors also use shockwaves for Peyronie's disease, which causes a curved penis. That use aims to ease pain, not to straighten the curve or improve erections. NICE guidance covers that indication separately from ED.
If you have both curvature and weaker erections, your urologist will usually assess them together. The phase of Peyronie's disease also affects which treatment makes sense.
How Dr. Taş assesses men who ask about shockwave therapy
At Safe Urology Clinic in Istanbul, Assoc. Prof. Dr. Tuncay Taş starts with the cause, not the machine. A short questionnaire scores erection quality. Then a review of medicines, heart risk and hormones follows.
If blood flow is in doubt, a penile Doppler ultrasound shows how well blood enters and stays. With that information, Dr. Taş can explain whether shockwave therapy is reasonable, or whether another option fits better.
For men who are good candidates, the clinic offers ED shockwave therapy as part of a wider plan. That plan may include tablets, lifestyle changes or treatment of an underlying condition. Men from the USA, Canada or the UK can also review all erectile dysfunction treatments first.
Some men have already tried tablets, injections and shockwaves without success. For them, a penile implant is often the most reliable next step. Dr. Taş will explain its benefits and risks openly, so you can compare it with less invasive choices.
Questions to ask before you pay for shockwave therapy
Clinics vary in how carefully they select patients. These questions help you judge whether a course is right for you.
What is the likely cause of my ED, and how was it confirmed?
Which type of device do you use, focused, linear or radial?
How many sessions are planned, and over how many weeks?
How will we measure whether the treatment has worked?
What will we do if there is no improvement after three months?
A good clinic will answer clearly and will not promise a cure. If the answers sound vague, or the plan skips an assessment, get a second opinion.
When to see a urologist
See a urologist if erection problems last more than a few weeks or keep coming back. Equally, seek advice if tablets no longer work or if ED affects your confidence and relationships. Book sooner in the following situations.
Your ED started suddenly or after an injury.
You also have chest pain, breathlessness or leg pain on walking.
You have diabetes, high blood pressure or high cholesterol.
You notice a new curve, lump or pain in the penis.
To discuss whether shockwave therapy suits you, book a consultation or message the team on WhatsApp. Dr. Taş will explain your options in plain terms and help you choose a realistic plan.
Frequently asked questions
Does shockwave therapy work for ED?
It can help some men, mainly those with mild ED caused by reduced blood flow. The effect in trials is modest and varies a lot between men. It works poorly when ED is severe or caused by nerve damage.
What is the success rate of shockwave therapy for ED?
There is no single reliable success rate. Studies use different machines, doses and definitions of success, so clinic figures are hard to compare. A Cochrane review found a small short-term effect and a possible longer-term benefit.
How long do the results of shockwave therapy last?
In men who respond, the benefit often lasts several months and may last longer. However, the conditions behind ED usually continue, so some men need a repeat course later. Long-term data is still limited.
Is shockwave therapy for ED painful?
Most men feel only tapping or mild discomfort, and no anaesthetic is needed. Side effects in trials were uncommon. Small bruises or brief soreness can occur, and they usually settle within days.
Is shockwave therapy for ED permanent?
No. It does not cure the causes of ED, such as diabetes, smoking or ageing arteries. If those causes continue, erections can weaken again over time. Treating them improves the chance of a lasting result.
Can I take tadalafil or sildenafil during shockwave therapy?
Yes, in most cases, and many men keep using tablets during and after the course. Some find that tablets work better afterwards, while others can lower the dose. Your urologist will advise you.
Do home shockwave devices work for ED?
There is little good evidence for home devices. Many of them produce radial pressure waves rather than focused shockwaves, and most trials used clinical machines. Ask a urologist before you buy one.
