Non-Surgical Peyronie's Disease Treatment: Who It's For

Peyronie's disease involves fibrous scar tissue, called a plaque, that forms beneath the skin of the penis and can cause palpable hardness, curvature, shortening, and painful erections. For a full explanation of causes, symptoms, and diagnosis, see our Peyronie's disease overview.

This guide focuses specifically on the non-surgical treatment options: which ones carry real evidence, which candidates suit each option, and how they compare to each other. Surgeons generally reserve surgery for stable, longstanding disease that has not responded to these conservative options; for that deep dive, see our guide to Peyronie's disease surgical correction.

Extracorporeal Shock Wave Therapy (ESWT)

ESWT is a non-invasive approach that targets the plaque directly with mechanical energy. Researchers do not fully understand the exact mechanism yet. However, the leading theory involves plaque regulation and tissue changes that may support gradual regression.

Some studies report meaningful improvements in pain scores and plaque size after ESWT. Overall, though, results remain inconsistent across the wider body of research. For this reason, current clinical guidelines do not recommend ESWT as a primary Peyronie's treatment, and Dr. Tas discusses this honestly with every patient who asks about it.

Collagenase Injections

Collagenase is an enzyme that breaks down collagen within the plaque itself. The surgeon injects it directly into the plaque, then follows up with manual modeling of the penis, both in clinic and at home, to help straighten the curvature over the course of treatment. Consequently, this treatment carries FDA approval for appropriate patients with noncalcified plaque.

Guideline criteria generally restrict candidacy to patients with stable disease, curvature between 30 and 90 degrees, and intact erectile function. In published trials, average curvature improvement with collagenase reached approximately 17 degrees, compared with 9.3 degrees for placebo, a modest but real, measurable benefit.

This benefit comes with real risks to weigh. Dr. Tas counsels every patient beforehand about possible adverse events, which include penile bruising, swelling, pain at the injection site, and, rarely, corporal rupture requiring urgent surgical repair. Plaque calcification, curvature severity, and overall anatomy all factor into candidacy, so a hands-on evaluation remains necessary before recommending this option.

Other Injectable Options

Beyond collagenase, urologists sometimes offer other intralesional injections for Peyronie's disease. Intralesional verapamil, a medication more commonly used for blood pressure, may help soften plaque tissue in select patients when injected directly into it. Intralesional interferon alpha-2b works through a different biological pathway and is another option some specialists consider.

Evidence for these alternatives remains less robust than for collagenase, and results vary meaningfully between patients. For this reason, Dr. Tas reserves these options for specific cases, after a full discussion of realistic expectations.

Penile Traction Therapy

Penile traction therapy uses a mechanical device to apply gentle, sustained stretching to the penis over weeks of daily use. Research shows it works safely and patients generally tolerate it well, and studies report an average curvature improvement of about 4 degrees or more with consistent use.

While that improvement sounds modest on its own, traction therapy works well as a companion to other treatments, particularly collagenase injections or post-surgical recovery, rather than as a standalone solution for significant curvature. Many patients also appreciate that it carries essentially no downtime, so daily life continues uninterrupted while the device does its work.

Choosing the Right Non-Surgical Peyronie's Disease Treatment

The right option depends on symptom duration, curvature severity, plaque calcification, and whether erectile function plays a role too. Early-stage disease sometimes calls for a period of observation, since some cases stabilize on their own.

Dr. Tuncay Tas reviews all of this during a consultation, and he explains the realistic outcomes and risks of each path clearly, rather than defaulting to a single approach for every patient. Many men benefit from combining approaches over time, for example starting with traction therapy while monitoring stability, then moving to collagenase or surgery if the disease does not improve on its own.

Who Is More Likely to Develop Peyronie's Disease?

Certain factors raise the likelihood of developing Peyronie's disease, even though the exact cause in any individual case often remains unclear. Diabetes and connective tissue disorders, such as Dupuytren's contracture, both appear more frequently in men who develop the condition, which suggests a shared underlying tendency toward excess scar tissue formation.

Age also plays a role, since Peyronie's disease becomes more common as men get older, likely because minor tissue injury takes longer to heal cleanly over time. Smoking and certain vascular risk factors may contribute as well, since they affect the body's healing response generally, not just in the penis specifically.

Knowing your own risk factors will not prevent the condition outright. Still, it helps explain why the disease appeared, and it gives Dr. Tas useful context when planning your treatment.
