# Peyronie’s Disease: Causes, Symptoms, Diagnosis, and Treatment Options

Peyronie’s disease is a medical condition that affects the penis and can cause it to bend or curve during an erection. It develops when scar tissue, known as plaque, forms beneath the skin of the penis. This tissue is less flexible than normal penile tissue, which may lead to curvature, discomfort, shortening, or difficulty during sexual activity.

Although a slight penile curve can be normal, a newly developed or worsening curve may indicate Peyronie’s disease. The condition can affect men physically and emotionally, sometimes causing anxiety, reduced confidence, and difficulties with intimacy. The good news is that several management options are available, depending on the severity of the curvature, the presence of pain, and whether the condition is stable or progressing.

Understanding the symptoms, possible causes, and available treatments can help men seek appropriate medical advice and make informed decisions about their health.

## What Is Peyronie’s Disease?

Peyronie’s disease occurs when fibrous scar tissue develops in the tunica albuginea, the tough layer of tissue surrounding the erectile chambers of the penis. During an erection, these chambers expand with blood. If scar tissue restricts expansion in one area, the penis may curve toward that side.

The direction and degree of curvature vary from person to person. Some men develop a mild bend without significant discomfort, while others experience severe curvature, pain, penile shortening, or difficulty achieving penetrative intercourse.

Peyronie’s disease is not a sexually transmitted infection, and it is not cancer. It is also not contagious. However, it may occur alongside erectile dysfunction, and both conditions may require evaluation.

## Common Symptoms of Peyronie’s Disease

Symptoms may develop gradually or become noticeable over a relatively short period. They can vary depending on the amount and location of scar tissue.

### 1. Curvature of the Penis

One of the most recognizable signs is a bend in the penis during an erection. The curvature may point upward, downward, or to either side. In some cases, the penis may develop an hourglass shape or a noticeable indentation.

### 2. Pain During Erections

Some men experience pain when the penis becomes erect. Pain may be more noticeable during the early, active phase of the condition and may improve over time. Pain that persists or worsens should be assessed by a healthcare professional.

### 3. Hard Lumps or Plaques

A firm area or lump beneath the penile skin may be felt along the shaft. These areas represent scar tissue and may be easier to notice when examining the penis while it is relaxed.

### 4. Penile Shortening

Some men notice that their erect penis appears shorter than it did before symptoms began. Scar tissue can restrict normal expansion and contribute to a loss of length.

### 5. Erectile Dysfunction

Peyronie’s disease can occur with erectile dysfunction (ED), which refers to difficulty achieving or maintaining an erection firm enough for sexual activity. Curvature, discomfort, anxiety, or changes in penile blood flow may contribute to sexual difficulties.

### 6. Difficulty With Sexual Activity

Severe curvature or pain may make sexual intercourse uncomfortable or difficult. These changes can also affect intimacy, self-esteem, and emotional well-being.

## What Causes Peyronie’s Disease?

The exact cause of Peyronie’s disease is not fully understood. It is commonly associated with an abnormal healing response following injury or repeated minor trauma to the penis. However, many men with the condition do not recall a specific injury.

Possible contributing factors include:

* **Penile injury:** Trauma during sexual activity, sports, or an accident may damage penile tissue.
* **Repeated minor trauma:** Small injuries that occur over time may contribute to scar tissue formation in susceptible individuals.
* **Abnormal wound healing:** Instead of healing normally, injured tissue may develop excessive fibrous scar tissue.
* **Genetic predisposition:** Some men may have an inherited tendency toward fibrotic conditions.
* **Age-related factors:** The condition is more frequently diagnosed in middle-aged and older men, although younger men can also develop it.
* **Associated fibrotic conditions:** Peyronie’s disease may occur alongside Dupuytren’s contracture, a condition that causes thickening and tightening of tissue in the palm of the hand.

These factors do not mean that every man exposed to penile trauma will develop Peyronie’s disease. In many cases, the exact cause remains unknown.

## Who Is at Greater Risk?

Peyronie’s disease can affect adult men of different ages, but certain factors may increase the likelihood of developing it.

Risk factors may include:

* Increasing age
* A history of penile trauma
* A family history of Peyronie’s disease
* Certain connective tissue disorders
* Previous penile surgery or injury
* Erectile difficulties that may increase the risk of injury during sexual activity

Having one or more risk factors does not guarantee that the condition will develop. A medical assessment is necessary to understand the cause of an individual’s symptoms.

## The Two Main Phases of Peyronie’s Disease

Doctors commonly describe Peyronie’s disease in two phases. Identifying the phase helps determine which treatment options may be appropriate.

### 1. Active Phase

During the active phase, the plaque and curvature may still be changing. Men may experience pain during erections, and the penis may gradually develop a more noticeable bend or indentation.

This phase can last several months and sometimes longer. Because symptoms may continue to change, treatment decisions should be made with a qualified urologist.

### 2. Stable Phase

The stable phase begins when the curvature and other symptoms stop changing significantly. Pain associated with erections often improves or disappears, although the curvature may remain.

Men with stable disease and significant deformity may be considered for specific procedures, including surgery, if the condition interferes with sexual function or causes substantial distress.

The duration and progression of each phase vary. A healthcare professional can help determine whether the condition appears active or stable.

## How Is Peyronie’s Disease Diagnosed?

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

### Medical History

The doctor may ask about when the curvature began, whether it is getting worse, the presence of pain, changes in penile length, erectile function, and any previous injuries or treatments.

### Physical Examination

The clinician may examine the penis for palpable plaques or areas of thickened tissue. The location and characteristics of the scar tissue can help guide the assessment.

### Photographs of an Erection

A doctor may ask the patient to provide private photographs of an erect penis from appropriate angles. These can help assess the direction and severity of the curvature when an in-office erection assessment is not performed.

### Ultrasound Examination

Penile ultrasound may be used to evaluate plaque characteristics and blood flow, particularly when erectile dysfunction is also present or further information is needed for treatment planning.

Not every patient requires every test. The diagnostic approach depends on symptoms, examination findings, and the treatment being considered.

## Treatment Options for Peyronie’s Disease

Treatment depends on the severity of curvature, the level of discomfort, the effect on sexual activity, erectile function, and whether the condition is still changing.

There is no single treatment that is suitable for every patient. Some men require reassurance and monitoring, while others may benefit from medication, injections, a traction device, or surgery.

### 1. Observation and Monitoring

Men with mild curvature, little or no pain, and no significant difficulty with sexual activity may not need immediate treatment. A urologist may recommend monitoring symptoms over time.

Observation does not mean ignoring the condition. Follow-up appointments can help identify changes that may require further assessment.

### 2. Medication for Pain

When pain is present, a healthcare professional may recommend suitable pain-relieving medication after considering the patient's medical history and other medicines.

Pain relief can help manage discomfort, but it generally does not remove established scar tissue or reliably correct penile curvature.

### 3. Intralesional Injections

Certain medicines can be injected directly into the plaque by a trained specialist. Collagenase clostridium histolyticum has been used for selected patients with an appropriate curvature pattern, where available and clinically suitable. Availability and approved indications vary by country.

Other injectable treatments may be considered in specific circumstances, but the strength of evidence differs. Potential risks include bruising, swelling, pain, and, rarely, serious penile injury. Patients should discuss the expected benefits and risks with their urologist.

### 4. Penile Traction Therapy

Penile traction devices apply controlled stretching to the penis over prescribed periods. Some studies suggest that traction may improve curvature or help preserve or increase penile length in selected patients.

Results depend on the device, adherence, treatment duration, and individual circumstances. A clinician should explain how to use a device safely and whether it is appropriate for the patient.

### 5. Vacuum Erection Devices

Vacuum erection devices use a cylinder and suction to draw blood into the penis. They are primarily used to assist erections and may be considered in selected treatment plans.

Evidence that vacuum devices alone reliably correct Peyronie’s curvature is limited. They should not be viewed as a guaranteed cure for the scar tissue.

### 6. Erectile Dysfunction Treatment

When Peyronie’s disease occurs with erectile dysfunction, treatment may be needed for both conditions. Depending on the assessment, a doctor may consider medicines such as phosphodiesterase type 5 inhibitors, including sildenafil or tadalafil, if appropriate.

These medicines help improve erections in many men but do not directly eliminate penile plaques or reliably straighten the penis. They may be unsuitable for people taking nitrate medicines and require medical review before use.

### 7. Surgery

Surgery may be considered when the curvature is stable and causes substantial difficulty with sexual intercourse or other significant functional problems. The choice of procedure depends on the degree of curvature, penile length, erectile function, and the patient's goals.

Common surgical approaches include:

* **Penile plication:** Tissue on the opposite side of the curve is shortened to help straighten the penis. It is often considered for suitable men with adequate penile length and good erectile function.
* **Plaque incision or excision with grafting:** The surgeon releases or removes selected portions of scar tissue and uses graft material to help restore shape. This may be considered for more complex deformities, but it carries a risk of erectile dysfunction.
* **Penile prosthesis:** For men who have significant erectile dysfunction that does not respond adequately to other treatments, a penile implant may be considered. Additional straightening techniques may be used when necessary.

Surgery can improve penile straightness, but no procedure guarantees a perfect result. Possible risks include changes in penile length or sensation, residual curvature, and erectile dysfunction. A detailed discussion with an experienced urologist is essential.

## Can Peyronie’s Disease Go Away on Its Own?

Peyronie’s disease may improve in some men, particularly when pain is the main symptom. However, established curvature often remains even after the pain subsides.

Spontaneous improvement varies, and it is difficult to predict the outcome for an individual. Men should not assume that the condition will disappear without evaluation, especially if the curvature is worsening or sexual activity has become difficult.

Early assessment can help establish a baseline and identify suitable management options.

## Is Peyronie’s Disease Permanent?

The condition can be long-lasting. In some cases, pain improves and the curvature stabilizes, but the scar tissue and deformity may persist.

The impact on sexual function varies. Some men continue to have satisfactory sexual activity without treatment, while others experience difficulties that warrant medical care.

The most appropriate plan depends on symptoms, the degree of curvature, erectile function, and personal preferences.

## Can Peyronie’s Disease Cause Erectile Dysfunction?

Yes. Peyronie’s disease and erectile dysfunction can occur together, although one does not always cause the other.

Possible reasons include:

* Changes in penile structure that affect erection quality
* Anxiety or stress related to curvature and sexual performance
* Pain or discomfort during sexual activity
* Other health conditions that affect blood flow or erectile function

Men who experience both penile curvature and erection difficulties should tell their doctor about both symptoms. Treating erectile dysfunction may improve sexual function, but it may not correct the curvature itself.

## Can Peyronie’s Disease Affect Fertility?

Peyronie’s disease does not usually directly affect sperm production. However, severe curvature or erectile dysfunction may make intercourse difficult, which can interfere with attempts to conceive.

Men concerned about fertility should discuss their circumstances with a qualified healthcare professional. Treatment can be tailored to the individual's sexual and reproductive goals.

## Lifestyle and Self-Care Tips

Although lifestyle changes cannot reliably remove penile scar tissue, healthy habits may support general sexual health and well-being.

* Avoid attempting to forcefully straighten the penis.
* Seek advice before using traction devices or other penile treatments.
* Avoid unverified supplements, creams, or online products that promise a permanent cure.
* Manage conditions such as diabetes, high blood pressure, and high cholesterol with appropriate medical care.
* Stop smoking if applicable, as smoking can harm vascular health.
* Discuss pain, erection difficulties, and emotional concerns openly with a healthcare professional.
* Follow the treatment plan and attend recommended appointments.

Do not attempt injections or invasive treatments at home. These procedures require appropriate medical training and sterile techniques.

## When Should You See a Doctor?

Arrange an appointment with a urologist if you notice a new penile curve, a hard lump beneath the skin, painful erections, penile shortening, or difficulty with sexual activity.

Seek urgent medical care if a penile injury is followed by a sudden popping sensation, immediate loss of erection, severe pain, rapid swelling, or significant bruising. These symptoms may indicate a penile fracture or another serious injury rather than uncomplicated Peyronie’s disease.

Prompt evaluation is particularly important when symptoms are changing rapidly or causing substantial pain.

## Frequently Asked Questions About Peyronie’s Disease

### 1. Is Peyronie’s disease dangerous?

Peyronie’s disease is generally not life-threatening, but it can cause pain, penile deformity, erectile dysfunction, and emotional distress. Medical assessment can help determine whether treatment is needed.

### 2. Is penile curvature always a sign of Peyronie’s disease?

No. Some men naturally have a slight curve that has been present since puberty. Peyronie’s disease is more likely when a new or progressive curve develops, especially alongside a firm plaque, pain, or changes in penile shape.

### 3. Can Peyronie’s disease be cured without surgery?

Some men can manage the condition without surgery. Non-surgical options may reduce symptoms or improve curvature in selected patients, but outcomes vary. No non-surgical treatment guarantees complete correction.

### 4. Does Peyronie’s disease affect sexual performance?

It can. Curvature, pain, erection difficulties, and anxiety may affect sexual activity. The degree of impact differs between individuals, and treatment may help improve function.

### 5. Can medicines straighten the penis?

Some treatments may improve curvature in selected cases, but ordinary pain medicines and erectile dysfunction medicines do not reliably straighten the penis. A specialist can explain the available options based on the patient's symptoms and disease stage.

### 6. Is Peyronie’s disease associated with age?

It is more commonly diagnosed in middle-aged and older men, but it can occur at other ages as well. Age alone does not establish the diagnosis.

### 7. Can I exercise to remove the plaque?

There is no established exercise that removes Peyronie’s plaque. Forceful stretching or unapproved techniques may cause further injury. If traction therapy is being considered, ask a urologist about safe use.

### 8. Which doctor treats Peyronie’s disease?

A urologist, particularly one experienced in male sexual medicine or reconstructive urology, is the most appropriate specialist for assessment and treatment planning.

## Conclusion

Peyronie’s disease is a condition involving scar tissue in the penis that may cause curvature, pain, shortening, and difficulties with sexual function. Although the symptoms and long-term effects vary, appropriate assessment can help men understand the condition and explore available treatments.

Management may include observation, pain relief, selected injections, penile traction, treatment for erectile dysfunction, or surgery in more severe cases. The best approach depends on the curvature, symptoms, erectile function, and whether the condition has stabilized.

If you notice a new or worsening penile curve, persistent pain, or difficulty with erections or intercourse, consult a qualified urologist rather than relying on self-treatment. Early evaluation can help you make informed decisions about your health and quality of life.
