What are low-intensity shock waves?
Shockwave therapy uses pulses of acoustic energy that have been used in medicine for years, initially to break up kidney stones. A low-intensity version is used to treat erectile dysfunction. These waves are applied to the penis with much less energy, enough to produce a biological effect without causing damage or pain, with the aim of stimulating and repairing it.
Difference between focal and radial shock waves
It is crucial to understand that not all shockwave therapy is the same. The strongest scientific evidence for erectile dysfunction supports the use of low-intensity focused or linear shockwaves, which are generated by electromagnetic, electrohydraulic, or piezoelectric devices. These produce a pressure wave that can be concentrated and precisely penetrate the deep tissues of the penis, such as the corpora cavernosa. They have demonstrated the greatest effectiveness in inducing angiogenesis (the formation of new blood vessels).
Radial shock waves, on the other hand, are lower-energy waves that disperse more superficially. Although they are used in physiotherapy for superficial tissues, current evidence shows less promising results for erectile dysfunction, as their penetration is limited and they do not reach deep vascular structures as effectively.

How do shockwaves work for erectile dysfunction?
The main cause of erectile dysfunction Arteriosclerosis, which is the narrowing of the arteries that carry blood to the penis due to factors such as smoking, diabetes, or high cholesterol, is of vascular origin.
Low-intensity shock waves act in a regenerative manner. When the waves are applied, a micromechanism is generated that stimulates the release of growth factors, such as vascular endothelial growth factor (VEGF). This promotes the formation of new blood vessels in the corpora cavernosa, improving blood flow.
They also promote relaxation of the vascular endothelium and enhance the release of nitric oxide, a key substance for blood vessel dilation and penile engorgement during erection. Several preclinical studies suggest they may also have reparative effects on damaged nerves, as well as antifibrotic and anti-inflammatory effects.
Unlike symptomatic treatments, shock waves seek to repair tissue by attacking the root of the vascular problem.

Benefits
Address the cause, not just the symptom
It is a regenerative therapy that attempts to restore the vascular anatomy of the penis, offering a potentially longer-lasting solution.
It is a non-invasive and painless treatment
It is performed on an outpatient basis, without the need for needles, scalpels, or anesthesia. The patient can return to their daily life immediately.
It improves the response to other treatments.
Many patients who did not respond well to oral medications (such as Viagra or Cialis) become "good responders" after completing therapy. Some may even be able to stop taking them.
High satisfaction rate and safety
Several studies show a positive response rate of up to 70-80%, and no significant side effects have been described, except for rare cases of small bruising.
lasting effect
Unlike medication, whose effect disappears within hours, the improvement achieved with shock waves is maintained over time, with studies confirming its effectiveness at 6, 12 and up to 30 months.
Who is it for?
Ideal candidates typically meet these profiles:
- Men with mild or moderate ED.
- Patients who respond partially to oral drugs (PDE5 inhibitors).
- Men with vascular risk factors (diabetes, hypertension, high cholesterol, obesity, sedentary lifestyle, smoking).
- Those who are looking for a non-pharmacological alternative or to reduce their dependence on medication.
Who are not ideal candidates?
The therapy is ineffective and therefore not recommended in cases of untreated erectile dysfunction of hormonal origin, such as hypogonadism or severe deficiency of testosterone, with erectile dysfunction due to venous leak (a problem in the venous retention system of the penis), with erectile dysfunction of purely psychological origin such as performance anxiety in young men without organic factors, with severe erectile dysfunction that does not respond at all to any oral drug, as this may indicate a lack of viable erectile tissue, nor for patients with uncontrolled coagulation disorders or taking anticoagulants.
How is it the procedure?
initial evaluation
The urologist will take a complete medical history and will often use questionnaires such as the International Index of Erectile Function (IIEF) to determine the severity of ED and confirm that the patient is a good candidate.
Treatment application
The patient lies down on an examination table. The doctor applies a conductive gel to the areas to be treated and places an applicator (transducer) on the skin of the penis.
Application areas
Shock waves are applied to different areas to cover the entire erectile tissue, mainly in the body of the penis (upper and sides) and in the root of the penis (crura), the area under the scrotum.
Post-treatment
Once the session is over, which usually lasts between 15 and 20 minutes, the patient can get dressed and go home without any restrictions.
Key points of the treatment
Duration of each session
Approximately 15 to 20 minutes.
Number of recommended sessions
The most common course is 4 to 6 sessions, usually once a week. Some more intensive protocols may include 12 sessions. An extra session one month after completion is often recommended.
Sensations during treatment
It is painless. Patients describe a tingling or light tapping sensation in the area, but without significant discomfort.
When are the results observed?
The improvement is not immediate. The first results usually begin to appear weeks after the sessions end, as the body needs time to form new blood vessels.
Expected results and clinical effectiveness
Studies show an average improvement of 3 to 7 points on the IIEF questionnaire (out of 25). Clinically, this translates to 70-80% of treated patients experiencing firmer erections and a significant improvement in their sexual function.
Factors that influence the success of the treatment
The best results are obtained in young patients with mild-to-moderate erectile dysfunction and no serious comorbidities. The presence of poorly controlled diabetes or hyperlipidemia may reduce efficacy.

Integration with other treatments
Changes in lifestyle
It is the fundamental pillar. Addressing sedentary lifestyles and poor diet is crucial for the success of vascular therapy.
Control of cardiovascular factors
Keeping hypertension, diabetes, and cholesterol under control through medication and diet is essential for long-term vascular health.
Hormone therapy indicated
If a testosterone deficiency exists, it must be corrected before or during shockwave therapy, as the hormone is necessary for the health of erectile tissue.
Psychological support or sex therapy
In cases where the psychological component is relevant, combining it with therapy can multiply the benefits, helping to break the vicious cycle of performance anxiety.
Factors that improve treatment outcomes
Diabetes and hypertension management
Maintain blood glucose and blood pressure within healthy ranges.
Quitting smoking
Tobacco is one of the main enemies of vascular health. Quitting is one of the most effective measures.
Weight loss
Reducing excess weight, especially abdominal fat, improves circulation and hormone levels.
regular physical exercise
Aerobic exercise such as running, swimming, or cycling improves endothelial function and overall cardiovascular health.
Improved cardiovascular health
Any measure that benefits your heart, benefits your erection.
Frequently Asked Questions (FAQs)
How many shockwave therapy sessions are needed for erectile dysfunction?
Generally, 4 to 6 sessions are recommended, performed once a week. Some centers may offer 12-session protocols.
How effective are shockwave therapy treatments for erectile dysfunction?
The treatment is highly effective in well-selected patients. Studies report positive response rates, with significant improvement, of around 70-80%.
What can go wrong with shockwave therapy?
It is an extremely safe treatment. No serious side effects have been reported. Occasionally, a small bruise or redness may appear at the application site, which disappears within a few days.
How long does it take for shock waves to take effect?
It's not immediate. The effect begins to be noticeable between 1 and 3 months after the complete treatment is finished, once the angiogenesis process has taken place.
How does shockwave therapy compare to Viagra?
Viagra is a symptomatic treatment taken before sexual intercourse that facilitates an erection while the drug is active. Shockwave therapy is a regenerative or curative treatment; that is, it aims to repair tissue so the patient can have natural erections without medication.
