Erectile dysfunction (ED) treatments have traditionally focused on medicines such as sildenafil, sold under the brand name Viagra. But a treatment that uses low-intensity sound waves is attracting growing interest as a potential alternative.

Known as low-intensity shockwave therapy, the non-invasive procedure aims to improve blood flow and potentially encourage the repair of penile tissue. However, despite growing demand, experts say there is not yet enough evidence to consider it a proven replacement for Viagra.

What Is Shockwave Therapy for ED?

Shockwave therapy uses a wand-like device to deliver acoustic pulses to several areas of the penis. Unlike the higher-energy shockwaves used to break up kidney stones, the goal here is not to destroy tissue.

Instead, the sound waves are thought to create tiny mechanical stresses that trigger biological responses involved in tissue repair and blood-vessel growth. This could potentially improve blood flow into the penis, which is essential for achieving and maintaining an erection.

A typical session in the UK lasts around 15 to 20 minutes, and individuals undergoing the procedure generally do not need anaesthesia. Depending on the condition, a full treatment may involve six to 12 sessions, with private treatment costs generally ranging from £150 to £320 per session.

A standard six-session course for conditions like erectile dysfunction (ED) typically costs around £1,000 to £1,500, although specialised diagnostic packages or longer treatment courses can push the total towards £1,900.

How Effective Is It?

The evidence so far is encouraging but far from conclusive. An early 2010 pilot study involving just 20 middle-aged men with ED found that half had improved enough six months after treatment to have penetrative sex without Viagra-type medication. However, the small size of the study makes it difficult to draw firm conclusions.

A 2025 Cochrane review examining 21 studies found that shockwave therapy may produce a small improvement in erectile function during the first few months and could have some longer-term benefits. However, differences between the studies reduced researchers' confidence in the findings.

Could It Replace Viagra?

Not yet. Sildenafil and other oral ED medicines work by increasing blood flow to the penis when sexual stimulation occurs. Shockwave therapy takes a different approach, attempting to address underlying blood-flow problems rather than temporarily helping an erection occur.

That distinction makes the treatment particularly interesting for men whose ED is linked to vascular problems, including conditions such as diabetes, high blood pressure, or high cholesterol. But ED can also have psychological, hormonal, medication-related, and other causes, meaning shockwave therapy is unlikely to be suitable for everyone.

The treatment is also not currently approved by the US Food and Drug Administration for ED, and major professional organisations, including the American Urological Association and the Sexual Medicine Society of North America, do not recommend its use outside clinical trials because the evidence remains insufficient.

Is Shockwave Therapy Safe?

Studies so far have not identified major safety concerns. Reported side effects have generally been minor, with skin reactions to the gel used during treatment among those noted in trials.

However, choosing a qualified healthcare professional matters. A 2022 analysis identified at least 152 clinics offering shockwave therapy across eight major US metropolitan areas, but only 25% of the providers were urologists.

For now, men experiencing persistent ED should speak to a healthcare professional rather than assuming sound-wave therapy is a proven substitute for medication. While the technology may eventually become an important treatment option, the science has not yet caught up with the hype.

Frequently Asked Questions

  • What is shockwave therapy for erectile dysfunction?
    Shockwave therapy is a non-invasive procedure that uses low-intensity sound waves to improve blood flow and potentially repair penile tissue.
  • How effective is shockwave therapy for ED?
    While early studies show some promise, the evidence is not yet conclusive, and more research is needed to confirm its effectiveness.
  • Can shockwave therapy replace Viagra?
    Not yet. Shockwave therapy addresses underlying blood-flow issues, whereas Viagra temporarily increases blood flow during sexual stimulation.
  • Is shockwave therapy safe?
    Studies have not identified major safety concerns, but it is important to choose a qualified healthcare professional for the treatment.
