Peyronie’s Disease is a connective tissue disorder of the penis that causes fibrous plaque formation within the tunica albuginea — the tough elastic sheath surrounding the erectile chambers (corpora cavernosa). This plaque leads to abnormal curvature, pain, shortening, and deformity of the penis during erection.
The condition can make sexual intercourse painful or difficult and can have a profound psychological impact on affected men. Though not cancerous or contagious, Peyronie’s Disease can severely affect sexual performance, body image, and self-confidence.
Fortunately, advances in urology and regenerative medicine have introduced multiple effective, evidence-based treatment options, ranging from medications and injections to shockwave and surgical correction.
Anatomy and Pathophysiology
The penis contains two long cylindrical structures called the corpora cavernosa, responsible for erections, and one smaller structure called the corpus spongiosum, which surrounds the urethra.
Each corpus cavernosum is covered by a tough fibrous layer — the tunica albuginea — which expands and stretches during erection to keep the penis straight.
In Peyronie’s Disease, microtears or trauma to the tunica albuginea trigger inflammation and abnormal collagen deposition.
Instead of healing normally, the tissue becomes fibrotic, forming dense, inelastic scar tissue (plaque).
This process prevents uniform expansion of the tunica during erection, leading to curvature, indentation, and sometimes pain.
Over time, the plaque can calcify, becoming hard and less responsive to conservative therapy.
Epidemiology
-
Peyronie’s Disease affects an estimated 3% to 13% of adult men.
-
Most commonly diagnosed between ages 40 and 70.
-
About 10%–20% of affected men also have
Dupuytren’s contracture — a hand condition involving fibrous thickening of tendons.
-
Underreporting is common because men often avoid discussing the condition due to embarrassment or stigma.
Causes and Risk Factors
The precise cause is multifactorial, involving both genetic and acquired factors.
1. Microtrauma and Repetitive Injury
-
Minor injury during sexual activity (e.g., bending of the penis during penetration) is the most recognized cause.
-
These microtears in the tunica albuginea initiate an abnormal wound-healing response.
-
Repeated trauma amplifies the scarring process.
2. Genetic and Familial Factors
-
Genetic predisposition is significant — men with Dupuytren’s contracture, Ledderhose disease, or plantar fibromatosis have a higher risk.
-
Mutations in collagen-related genes may alter normal wound healing.
3. Age-Related Changes
-
With aging, the tunica becomes less elastic and more susceptible to injury and fibrosis.
4. Health and Metabolic Conditions
-
Diabetes mellitus, hypertension, high cholesterol, and vascular disease impair healing and circulation.
-
These comorbidities can worsen the fibrotic process.
5. Hormonal and Lifestyle Factors
-
Low testosterone, smoking, and alcohol abuse are known contributors.
-
Oxidative stress and inflammation are higher in these men.
6. Iatrogenic Causes
-
Penile trauma during certain procedures (e.g., catheterization or penile prosthesis surgery).
Symptoms and Clinical Presentation
Symptoms vary depending on the stage and severity of disease.
1. Penile Curvature
-
The most common sign.
-
Curvature direction depends on plaque location:
-
Dorsal (upward) – most common.
-
Ventral (downward) – less common but can cause pain.
-
Lateral (sideways) – depending on which side is affected.
-
-
Degree of curvature may range from mild (10–20°) to severe (>60°).
2. Pain
-
Often present in the acute (early) phase.
-
Caused by active inflammation and microtears.
-
Typically subsides once the plaque stabilizes.
3. Palpable Plaque
-
A firm, flat or nodular lump can be felt along the shaft.
-
May feel like a “cord” or “flat pebble.”
4. Penile Shortening
-
Due to tissue contraction on the affected side.
5. Erectile Dysfunction (ED)
-
Found in 30–50% of cases.
-
May result from poor venous occlusion, impaired elasticity, or anxiety.
6. Deformities
-
Indentation or “hourglass” shape deformity.
-
“Bottleneck” appearance in advanced cases.
7. Psychological Effects
-
Depression, anxiety, sexual avoidance, and relationship difficulties are common.
-
Up to 80% of men report significant emotional distress.
Stages of Peyronie’s Disease
1. Acute (Inflammatory) Stage
-
Duration: 6–18 months.
-
Pain and progressive curvature.
-
Plaque still forming; disease is active.
-
Ideal time for non-surgical interventions.
2. Chronic (Stable) Stage
-
Pain subsides.
-
Curvature stabilizes.
-
Plaques may calcify or harden.
-
Surgery becomes a more viable option if deformity interferes with intercourse.
Diagnosis
1. Medical and Sexual History
-
Discussion of trauma, onset, and progression.
-
Assessment of erectile function and psychological impact.
2. Physical Examination
-
Palpation of plaques on flaccid penis.
-
Evaluation of curvature direction and extent.
3. Penile Ultrasound (Doppler)
-
Detects plaque size, calcification, and blood flow patterns.
-
Assesses erectile tissue health.
4. Erection Assessment
-
May involve intracavernosal injection of vasoactive agents to induce erection.
-
Enables accurate measurement of curvature.
5. Photographic Documentation
-
Photos of natural erection (at home) can help track disease progression.
Treatment Options
Treatment depends on:
-
Phase of disease (acute vs. chronic)
-
Severity of curvature
-
Pain level
-
Erectile function
-
Psychological impact
A. Conservative and Medical Treatments (Non-Surgical)
1. Oral Medications
-
Used mainly during the acute phase to reduce inflammation and fibrosis.
a. Pentoxifylline:
Improves blood flow, inhibits collagen deposition, and may reduce calcification.
b. Vitamin E:
Antioxidant that may provide modest benefits; often used as adjunctive therapy.
c. Colchicine:
Reduces inflammation and fibroblast activity.
d. Potassium Para-Aminobenzoate (Potaba):
Inhibits fibrosis; may reduce plaque size with consistent use.
e. Acetyl-L-Carnitine:
Shown in some studies to decrease curvature and pain.
Note: Oral medications are typically supportive and rarely reverse established curvature alone.
2. Intralesional Injection Therapy
Injecting medication directly into the plaque provides higher local concentration and better results.
a. Collagenase Clostridium Histolyticum (Xiaflex)
-
Only FDA-approved drug for Peyronie’s Disease.
-
Breaks down excess collagen within plaque.
-
Administered in several cycles (usually 4) combined with penile modeling exercises.
-
Average curvature improvement: 30–40%.
-
Minimal downtime, high satisfaction.
b. Verapamil Injections
-
Calcium channel blocker.
-
Reduces collagen synthesis and promotes plaque softening.
-
Often used where Xiaflex is unavailable.
c. Interferon Alpha-2b
-
Inhibits fibroblast proliferation and collagen production.
-
Reduces plaque size and penile pain.
3. Extracorporeal Shockwave Therapy (ESWT)
-
Low-intensity acoustic waves targeted at the plaque.
-
Reduces penile pain and may help soften fibrotic tissue.
-
Non-invasive and painless; performed in outpatient setting.
-
Evidence supports pain reduction more than curvature correction.
4. Penile Traction Therapy (PTT)
-
Uses a mechanical stretching device for several hours daily.
-
Helps remodel tissue, increase length, and reduce curvature.
-
Often combined with collagenase therapy.
-
Demonstrated to improve penile length by 1–2 cm and curvature by up to 20%.
5. Regenerative Medicine Therapies
a. Platelet-Rich Plasma (PRP) Therapy
-
Uses patient’s own blood to isolate plasma rich in growth factors.
-
Injected into the affected area to stimulate healing and reduce fibrosis.
-
Shown to improve elasticity and reduce pain in some studies.
b. Stem Cell Therapy
-
Emerging therapy using adipose or bone marrow-derived stem cells.
-
Promotes regeneration of healthy tissue.
-
Still under clinical investigation but promising for early disease management.
B. Surgical Treatments
Surgery is reserved for patients with:
-
Stable disease for >6 months
-
Severe curvature (>60°)
-
Difficulty or impossibility with sexual intercourse
-
Non-response to conservative therapies
1. Tunical Plication (Shortening Procedure)
-
Sutures placed opposite the curvature to straighten the penis.
-
Simple, safe, and effective for mild to moderate curvature.
-
May result in minor penile shortening (0.5–1.5 cm).
2. Plaque Incision/Excision with Grafting
-
Plaque is incised or removed, and a graft (biological or synthetic) is applied to restore symmetry.
-
Used for complex deformities or hourglass shapes.
-
Maintains penile length but higher risk of erectile dysfunction.
3. Penile Prosthesis Implantation
-
Recommended for men with Peyronie’s Disease and erectile dysfunction.
-
Inflatable or malleable implants straighten the penis and restore rigidity.
-
Provides both functional and aesthetic correction.
Psychological and Emotional Support
-
Peyronie’s Disease often causes anxiety, shame, and relationship issues.
-
Counseling and sex therapy are crucial parts of holistic management.
-
Partner involvement improves emotional healing and treatment outcomes.
Prognosis
-
10–20% of cases may improve spontaneously.
-
40–50% remain stable.
-
30–40% worsen over time without treatment.
-
Early medical therapy can prevent progression.
-
Surgical results are excellent when performed by experienced urologists.
Prevention and Healthy Habits
While not always preventable, certain measures can reduce risk:
-
Avoid rough or high-impact sexual activity.
-
Use proper lubrication during intercourse.
-
Manage diabetes, hypertension, and cholesterol.
-
Quit smoking and limit alcohol.
-
Maintain healthy testosterone levels.
Conclusion
Peyronie’s Disease is a complex but highly treatable condition. Advances in urology, regenerative medicine, and microsurgery now allow men to regain both physical function and confidence.
Early diagnosis is key — when detected in its initial stages, Peyronie’s Disease can often be treated without surgery, preventing long-term deformity and discomfort.
If you notice curvature, pain, or a lump in your penis, don’t delay. Consult a qualified urologist or men’s health specialist for accurate diagnosis and individualized treatment.
With modern therapies like collagenase injections, traction therapy, PRP, and surgical correction, Peyronie’s Disease no longer has to define your sexual health — or your confidence.
