Erectile dysfunctionA comprehensive protocol, without surgery

Erectile dysfunction has several causes: vascular, neurological, metabolic or stress-related. The protocol combines P-Shot, stem cells, shockwave therapy and a hyperbaric chamber, without surgery or implants. The consultation is private and confidential.

Quick answer

How is erectile dysfunction treated with stem cells?

The protocol combines P-Shot, mesenchymal stem cells, shockwave therapy and hyperbaric chamber, with no surgery or implants. It is outpatient and done under sedation. The first consultation with Dr. Guerrero Silva is private and confidential, includes a full assessment of your case and is the mandatory first step.

Is it for me?

For men with erectile dysfunction of any origin. The initial consultation with Dr. Guerrero Silva includes a full assessment of your case and is the mandatory first step.

If you recognize yourself in any of these

You have erectile dysfunction, whatever its origin.
Medications (Viagra, Cialis) have not worked well for you.
You have diabetes or cardiovascular problems that affect your sexual function.
You want to stop depending on medication.
You are over 30 and your sexual performance is gradually declining.

It is not for you if there is

Active prostate cancer
Severe coagulation disorders
Patients who don’t meet prior medical evaluation criteria

The initial evaluation confirms it.

What will be done?

What it is

P-Shot is a regenerative procedure that uses growth factors derived from your own cells to stimulate regeneration of erectile tissue and improve local circulation. It is combined with mesenchymal stem cells, shockwave therapy and a hyperbaric chamber in a protocol that acts on the tissues responsible for erectile function.

How it works

Vascular originProblems in small arteries that reduce the blood flow needed for an erection. Shockwave therapy and the P-Shot regenerate damaged vessels.
Neurological originDamage to distal nerves that disrupts the signals needed for erectile response. Stem cells stimulate nerve regeneration.
Metabolic originDiabetes, hypothyroidism, and other hormonal disorders that affect sexual function. Our protocol addresses the systemic origin.
Stress and psychogenic factorsChronic stress and performance anxiety create a cycle that perpetuates dysfunction. The comprehensive treatment breaks that cycle at the biological level.

Step by step

1
Initial evaluation
A consultation with Dr. Guerrero Silva. He reviews your history and tests to decide whether you are a candidate and what to aim for with treatment.
45-minute consultation, virtual or in person
2
Protocol design
A plan made for you: type of stem cells, concentration, delivery route and complementary therapies such as IV therapy, laser or magnetotherapy.
Depending on your case: IV therapy, laser or magnetotherapy
3
Treatment
Performed in facilities licensed by the Bogotá Health Department. The cells are processed in biosafety level II laboratories.
Continuous medical supervision
4
Follow-up
Medical check-ups after treatment to verify how you respond and adjust the protocol.
We don’t promise cures: we pursue real, sustainable, measurable results

The protocol, in four treatments

They are combined into a single plan, designed in your consultation.

P-ShotLocal application of concentrated growth factors to stimulate regeneration of erectile tissue and improve sensitivity. Performed under sedation by specialists.
Mesenchymal Stem CellsSystemic and local application of stem cells that regenerate the vascular and nerve tissue responsible for erectile function.
Shockwave TherapyShock wave therapy that activates angiogenesis — the formation of new blood vessels — sustainably improving blood flow.
Hyperbaric Chamber and IV TherapyDeep cellular oxygenation and intravenous nutrition that boost and accelerate all protocol results.

How many sessions and what results?

Every case progresses differently: these are the usual milestones of follow-up. We do not promise cures; we aim for real, sustainable and measurable results.

Procedure: The whole protocol is done under sedation, with anesthesiology specialists; you go home the same day.
Tests: The initial consultation includes a full assessment of your case; it is the first step.
Privacy: Private and confidential consultation, from the first visit to follow-up.

First weeks
- First improvements between 2 and 4 weeks
- Greater sensitivity
1 to 3 months
- More sustained erections
- Less performance-related stress
6 months or more
- Optimal results between 2 and 3 months
- Long-lasting effects, depending on each case

Frequently asked questions

Is the procedure painful?

No. The entire protocol is performed under sedation by anesthesiology specialists. The patient feels no pain during the procedure and recovery is nearly immediate.

When are results visible?

Most patients report improvements from the first 2-4 weeks. Optimal results are reached between 2 and 3 months after treatment, once cellular regeneration is complete.

How long does the treatment effect last?

Effects are long-lasting thanks to real tissue regeneration. Unlike medications, the SANAA protocol acts on the cause, not the symptom.

Is it completely private and confidential?

Yes. We guarantee absolute privacy throughout the process: from the initial consultation to post-treatment follow-up. No data is shared.

Does it work if I have diabetes?

Yes. The protocol is specifically designed to address the metabolic origin of erectile dysfunction, including diabetes as an underlying cause.

Do I need prior tests?

Yes. The initial consultation with Dr. Guerrero Silva includes a complete case assessment to determine the most appropriate protocol. It’s the required first step.

Is stem cell therapy for ED a real, evidence-based option?

Yes. Our ED protocol combines mesenchymal stem cells with the P-Shot, shockwave therapy, and hyperbaric oxygen to address the vascular, neurological, and metabolic causes of erectile dysfunction — not just the symptom. It’s evaluated case by case starting with a private consultation with Dr. Guerrero Silva.
