Peyronie’s disease is a condition that affects the shape and structure of the penis, causing it to bend or curve during an erection. It develops when fibrous scar tissue, known as plaque, forms beneath the skin of the penis. Depending on the location and severity of the scar tissue, men may experience penile curvature, pain during erections, shortening of the penis, or difficulty with sexual intercourse.

Although Peyronie’s disease can be uncomfortable and emotionally distressing, it is not cancer and is not a sexually transmitted infection. Several treatment options are available, and the right approach depends on the severity of the curvature, the stage of the condition, and whether erectile dysfunction is also present.

Understanding the symptoms, causes, and treatment options can help men recognize the condition early and seek appropriate medical care.

What Is Peyronie’s Disease?

Peyronie’s disease is a connective tissue disorder characterized by the development of fibrous scar tissue in the tunica albuginea, the elastic membrane surrounding the erectile chambers of the penis.

During a normal erection, blood fills the erectile chambers, allowing the penis to expand. When scar tissue develops in part of the surrounding membrane, that area may not stretch normally. This causes the penis to bend toward the affected side.

The curvature can occur upward, downward, or toward either side. Some men develop a mild curve, while others experience significant bending, indentation, an hourglass-shaped appearance, or penile shortening.

Peyronie’s disease affects every individual differently. In mild cases, the curvature may not interfere with sexual activity. In more severe cases, it can cause pain, difficulty with penetration, or erectile dysfunction.

Common Symptoms of Peyronie’s Disease

The symptoms of Peyronie’s disease may develop gradually or become noticeable over a short period. Some symptoms occur mainly during an erection, while others can be detected when the penis is flaccid.

1. Curvature of the Penis

Penile curvature is the most recognizable symptom of Peyronie’s disease. The penis may bend upward, downward, or to either side during an erection.

A slight curve does not necessarily indicate a medical problem. However, a new or worsening curve, particularly when accompanied by pain or a firm lump, should be evaluated by a urologist.

2. Hard Lumps Beneath the Skin

Some men notice a firm area or lump along the shaft of the penis. This may represent the fibrous plaque associated with Peyronie’s disease.

The plaque can vary in size and location. Because other conditions can also cause penile lumps, a medical examination is important for an accurate diagnosis.

3. Pain During Erections

Pain is more common during the active phase of Peyronie’s disease. Men may experience discomfort when the penis becomes erect or during sexual intercourse.

The pain may improve naturally as the condition stabilizes, but this does not necessarily mean the curvature will disappear.

4. Shortening of the Penis

Scar tissue can restrict the normal expansion of the penis, making it appear shorter during an erection. The amount of shortening varies depending on the extent and location of the plaque.

This change can affect body image and sexual confidence.

5. Indentation or Hourglass Deformity

Some men develop a narrowed section along the shaft, creating an indentation or hourglass-shaped appearance during an erection.

In more severe cases, this deformity may affect the structural stability of the penis and cause it to bend or buckle during sexual activity.

6. Erectile Dysfunction

Peyronie’s disease may occur alongside erectile dysfunction, which is the difficulty of achieving or maintaining an erection firm enough for satisfactory sexual activity.

The problem may result from changes in penile structure, impaired blood flow, pain, or anxiety related to sexual performance.

7. Emotional Stress

Changes in penile appearance and sexual function can affect confidence, relationships, and emotional well-being. Some men experience anxiety or embarrassment about intimacy.

Seeking medical advice and discussing concerns openly with a partner can help reduce stress and improve quality of life.

What Causes Peyronie’s Disease?

The exact cause of Peyronie’s disease is not fully understood. However, it is often associated with an abnormal healing response following injury to the penis.

Penile Injury

Repeated minor injuries or a more significant injury during sexual activity, sports, or an accident may damage the tissues inside the penis. During healing, excessive scar tissue may develop and cause curvature.

Many men do not remember a specific injury, so the condition can occur without an obvious triggering event.

Abnormal Scar Formation

In Peyronie’s disease, the body's healing process may result in excessive collagen accumulation. This produces a firm plaque that does not stretch like the surrounding tissue.

As the plaque develops, it can interfere with the normal expansion of the penis during an erection.

Genetic Factors

Some men may have an inherited tendency to develop Peyronie’s disease or other fibrotic conditions. However, having a family history does not mean that the condition will inevitably develop.

Age-Related Changes

Peyronie’s disease is more commonly diagnosed in middle-aged and older men. Changes in tissue flexibility and healing may contribute to the increased risk, although younger men can also develop the condition.

Associated Health Conditions

Certain medical conditions, including diabetes, erectile dysfunction, and some connective tissue disorders, have been associated with Peyronie’s disease. These associations do not mean that any one condition directly causes the disease in every patient.

Stages of Peyronie’s Disease

Peyronie’s disease generally progresses through two phases: the active phase and the stable phase.

Active Phase

During the active phase, the plaque is developing and the curvature may change over time. Pain during erections is common, and the penis may gradually become more curved or develop additional deformities.

This phase often lasts several months and may continue for approximately 12–18 months, although the duration varies between individuals.

Stable Phase

During the stable phase, the curvature generally stops changing significantly. Pain often improves or disappears, but the existing deformity may remain.

Treatment may still be helpful if the curvature affects sexual activity, causes significant distress, or is associated with erectile dysfunction.

How Is Peyronie’s Disease Diagnosed?

A urologist can usually diagnose Peyronie’s disease through a medical history and physical examination. Additional tests may be recommended when necessary.

Medical History

The doctor may ask when the curvature began, whether it is getting worse, and whether pain or erectile dysfunction is present. Questions about previous injuries, existing medical conditions, and the effect on sexual activity may also be included.

Physical Examination

The urologist examines the penis and may feel for firm plaques beneath the skin. This helps identify the location of the scar tissue and assess the physical changes.

Erection Assessment

Because the curvature is most visible during an erection, the doctor may ask for photographs of the erect penis taken from appropriate angles. In selected cases, medication may be administered in the clinic to produce an erection for a more detailed assessment.

Penile Ultrasound

Ultrasound may help identify plaques, assess calcification, and evaluate blood flow. It is particularly useful when erectile dysfunction is present or when an invasive treatment is being considered.

Not every patient requires imaging. The tests depend on the clinical findings and the treatment plan.

Treatment Options for Peyronie’s Disease

Treatment depends on the severity of the curvature, whether the condition is still progressing, the presence of pain, and the patient's sexual function and preferences.

Some men with mild symptoms may only need monitoring. Others may benefit from medication for pain, plaque injections, penile traction therapy, or surgery.

1. Observation and Monitoring

Men with mild curvature and no significant pain or sexual difficulties may choose to monitor the condition with their urologist.

Observation can be appropriate when the expected benefits of active treatment are limited. However, worsening curvature or new symptoms should prompt reassessment.

2. Medication for Pain

Anti-inflammatory medication may help reduce pain during the active phase, provided it is safe for the individual.

These medicines do not reliably dissolve plaque or straighten the penis. A healthcare professional should advise on suitable options, particularly for patients with kidney problems, stomach ulcers, or cardiovascular conditions.

3. Collagenase Injections

Collagenase injections are designed to break down collagen within the scar tissue. In countries where collagenase clostridium histolyticum is licensed and available, it may be considered for selected patients.

Treatment generally involves injections into the plaque, often combined with clinician-directed penile modeling.

Possible side effects include bruising, swelling, pain, and, rarely, serious penile injury. Eligibility and availability depend on the curvature pattern, plaque characteristics, local authorization, and the patient's medical circumstances.

4. Other Plaque Injections

Other injectable treatments, including verapamil and interferon alfa-2b, have been used in selected cases. Their effectiveness and suitability vary, and the evidence supporting them is not identical.

A urologist can explain the potential benefits, limitations, risks, and availability of these options.

5. Penile Traction Therapy

Penile traction therapy involves using a medical device to apply a controlled stretching force to the penis.

Some men may experience improvements in curvature or preservation of penile length, but results vary. Treatment requires consistent use according to a clinician's instructions, often over several weeks or months.

Forceful manual stretching or using an unsuitable device can cause injury and should be avoided.

6. Vacuum Erection Devices

Vacuum erection devices use negative pressure to draw blood into the penis and produce an erection. They may be considered in selected treatment plans, particularly when erectile function is also a concern.

However, they are not a proven cure for Peyronie’s disease, and evidence that they reliably correct curvature is limited.

7. Surgery for Peyronie’s Disease

Surgery may be recommended when the curvature has stabilized and significantly interferes with sexual intercourse or causes substantial distress.

Common surgical approaches include:

• Penile plication: Sutures are placed on the opposite side of the curvature to straighten the penis. The procedure may cause some shortening.

• Plaque incision or excision with grafting: The scar tissue is released or, in selected cases, removed, and a graft is used to help restore a straighter shape. This may be appropriate for complex deformities but carries a risk of erectile dysfunction or altered sensation.

• Penile implant surgery: A penile implant may be considered for men with Peyronie’s disease and significant erectile dysfunction that does not respond adequately to other treatments.

Surgery is generally considered when the condition is stable and the expected benefits outweigh the risks. The best procedure depends on penile length, curvature severity, erectile function, and individual goals.

8. Oral Supplements and Alternative Treatments

Some supplements and oral medicines are promoted online as treatments for Peyronie’s disease. However, no oral medication or supplement has been established as a reliable way to reverse penile curvature.

Men should be cautious of products promising a permanent cure or claiming to dissolve scar tissue without medical treatment.

9. Shockwave Therapy

Shockwave therapy has been studied for Peyronie’s disease. It may help relieve penile pain in some patients, but it has not been established as a reliable method of correcting curvature.

Patients should understand the limitations of this treatment before considering it.

Peyronie’s Disease and Erectile Dysfunction

Peyronie’s disease and erectile dysfunction can occur together and may require a combined treatment approach.

A urologist may recommend erectile dysfunction medication, an assessment of penile blood flow, treatment for the curvature, or other interventions depending on the cause of the erection problem.

Medicines such as sildenafil or tadalafil may help men who are suitable candidates, but they do not directly dissolve Peyronie’s plaques.

For men with severe erectile dysfunction that does not respond adequately to other treatments, a penile implant may be an option. In selected cases, additional procedures can be performed during implant surgery to improve penile straightness.

Can Peyronie’s Disease Go Away Naturally?

Peyronie’s disease sometimes improves without active treatment, but spontaneous recovery is unpredictable.

Pain often decreases as the condition stabilizes. However, the curvature, shortening, or indentation may remain even after pain has resolved.

Men with mild symptoms may choose observation under medical guidance. Those with progressive curvature, persistent pain, or difficulty with sexual intercourse should seek assessment from a urologist.

Even if the condition has been present for a long time, treatment may still improve the curvature or sexual function.

Possible Complications of Peyronie’s Disease

Peyronie’s disease is generally not life-threatening, but it can affect physical and emotional well-being.

Potential complications include:

• Persistent penile curvature.

• Loss of penile length.

• Erectile dysfunction.

• Pain during erections or sexual intercourse.

• Difficulty with penetration.

• Anxiety and reduced sexual confidence.

• Emotional distress and relationship difficulties.

The severity of these complications varies. Early evaluation can help determine which treatments may provide meaningful benefits.

Lifestyle Tips for Managing Peyronie’s Disease

Lifestyle changes cannot reliably eliminate the scar tissue, but certain measures can support sexual health and help prevent further injury.

Avoid Forceful Bending

Avoid activities or sexual positions that repeatedly cause painful bending or excessive pressure on the erect penis. Stop sexual activity if significant pain occurs.

Manage Underlying Health Conditions

Managing diabetes, high blood pressure, high cholesterol, and cardiovascular disease can support general and erectile health.

Avoid Unsupervised Treatments

Do not attempt to straighten the penis through forceful bending, aggressive massage, or unregulated devices. These practices can cause additional injury.

Communicate With Your Partner

Open communication about pain, intimacy, and treatment concerns can reduce anxiety and help couples maintain a satisfying relationship.

Seek Emotional Support

If Peyronie’s disease affects confidence, mood, or relationships, professional counseling may be beneficial alongside medical treatment.

When Should You See a Doctor?

Consult a urologist if you notice a new or worsening penile curve, a firm lump beneath the skin, pain during erections, penile shortening, indentation, or difficulty maintaining an erection.

Prompt medical evaluation is particularly important when symptoms interfere with sexual activity or continue to progress.

Seek urgent medical care after an erection-related injury if you experience a popping sound, sudden severe pain, rapid loss of erection, substantial swelling, or bruising. These symptoms may indicate a penile fracture or another serious injury.

Frequently Asked Questions About Peyronie’s Disease
