What Is Peyronie's Disease? Symptoms & What It Looks Like

Peyronie's disease is a condition where scar tissue, called plaque, forms inside the penis. The scar can stop part of the penis from stretching normally during an erection. This may cause a bend or a change in shape. Some men also develop erection problems. A small natural curve is common and does not mean you have Peyronie’s disease. The concern is a new or worsening change, especially when it causes pain or makes sex difficult. Current 2026 reference data from the U.S. National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) says about 1 in 100 adult men in the U.S. have been diagnosed, while symptom-based studies suggest the actual rate may be higher than 1 in 10.

What Is Peyronie's Disease?

Peyronie’s disease happens when fibrous scar tissue forms in the tunica albuginea. This is the elastic layer around the erectile tissue of the penis.

The scar does not stretch like healthy tissue. During an erection, the unaffected side can expand while the scarred area stays tight. This pulls the penis toward the scarred side. That is why the main visible sign is often a new curve during an erection.

The curve may point:

• Upward

• Downward

• To the left or right

• In another direction, depending on where the plaque forms

The condition is benign, which means the plaque itself is not cancer. Peyronie’s disease can develop after an injury or repeated minor injury. However, many men cannot remember hurting their penis. Researchers also link the condition with abnormal healing and certain connective-tissue or autoimmune conditions.

What Does Peyronie's Disease Look Like?

The appearance can vary a lot from one person to another. There is no single shape that proves you have the condition. A common sign is a noticeable bend that appears or becomes stronger during an erection. You may also see a dent, narrowing, or a shorter-looking penis.

Common visible changes include:

• A new upward, or sideways curve

• A dent along one side of the shaft

• Narrowing around part of the shaft

• An hourglass-like shape

• A shorter penis during an erection

• A change in the shape of an erection

A hard area or lump may also be felt under the skin. The plaque may be easier to feel when the penis is soft. It is not always visible from the outside.

Peyronie's Disease: Common Appearance vs Symptom

What Are the Symptoms of Peyronie's Disease?

The symptoms can appear slowly or develop over a shorter period. They can also change over time. The most common signs include:

1. Penile curvature

A new curve is one of the main signs. The curve may be mild or severe. A small curve that has always been present is often normal. Peyronie’s disease is more concerning when the curve is new, becomes worse, or comes with other symptoms.

2. A hard lump or plaque

You may feel a firm area beneath the skin. It may feel like a flat lump or a band of hard tissue. The area can sometimes be tender, especially during the earlier stage of the condition.

3. Pain

Pain may occur when the penis is erect. Some men can also have pain when the penis is soft. Pain often becomes less noticeable with time. However, the curve or change in shape may remain.

4. Shortening

The penis can appear shorter during an erection. This happens because the scar tissue can prevent normal expansion. Some men also notice a loss of girth in part of the shaft.

5. Changes in shape

Some men develop a dent or narrow section. Others develop an hourglass shape. These changes may be easier to see during an erection.

6. Erectile dysfunction

Some men with Peyronie’s disease have trouble getting or keeping an erection. Erection problems can occur because of changes in the penis itself. Pain, stress, and concern about appearance can also affect sexual function.

What Causes Peyronie's Disease?

The exact cause is not fully known. One leading explanation is repeated injury to the penis. This can happen during sex, sports, or an accident. Small injuries may happen without causing obvious pain at the time.

The body then repairs the injured tissue. In some men, abnormal scar tissue develops during this process. The scar can form a plaque in the tunica albuginea.

Not every injury causes Peyronie’s disease. Many men with the condition do not remember any specific injury.

Certain factors may also raise the risk. These include:

• Increasing age

• A family history of Peyronie’s disease

• Certain connective-tissue disorders

• Some autoimmune conditions

• Diabetes, especially when erectile dysfunction is also present

• Previous prostate cancer surgery

Mayo Clinic notes that the condition is more common between ages 45 and 70, although it can occur at other ages.

What Does Peyronie's Disease Look Like During an Erection?

An erection can make the changes easier to see. The penis may curve toward the area where the plaque has formed. For example, scar tissue on the upper side may cause an upward curve. Scar tissue on the lower side may cause a downward curve.

A plaque affecting more than one area can cause a dent or more complex change in shape. In some cases, scar tissue can form around the shaft. This can create a narrow section that gives the penis an hourglass appearance.

It is important to remember that a curved penis does not automatically mean Peyronie’s disease. Many men naturally have some curvature. A curve that has been present for as long as you can remember and has not changed may be normal. A new curve, or difficulty with sex, deserves a medical assessment.

How Is Peyronie's Disease Diagnosed?

A urologist usually starts with your medical history and a physical examination.

The doctor may ask:

• When did you first notice the change?

• Has the curve become worse?

• Do you have pain?

• Can you feel a hard area?

• Are erections affected?

• Has sex become difficult?

• Do you remember an injury?

• Does anyone in your family have Peyronie’s disease?

The doctor may feel the plaque while the penis is soft. In some cases, an erection may need to be assessed. A doctor may also ask you to provide photographs of an erection so the curve can be evaluated. Imaging, such as ultrasound, may be used when more information about the plaque or blood flow is needed.

When Should You See a Doctor?

See a doctor if you notice a new or changing curve, especially when you also have pain or a hard lump.

You should also seek medical advice if:

• The curve makes sex difficult

• Erections have become painful

• You have trouble getting or keeping an erection

• Your penis looks shorter than before

• You notice an indentation or hourglass shape

• The change is causing significant worry or relationship problems

You do not need to wait until the curve becomes severe. A urologist can determine whether the change is caused by Peyronie’s disease, normal curvature, an injury, or another condition.

Can Peyronie's Disease Get Better?

Peyronie’s disease often has an active stage followed by a more stable stage. During the active stage, the curve or other shape changes can develop or worsen. Pain is also more common during this period.

Later, the condition may become stable. Pain often decreases, but the plaque and curvature can remain. NIDDK describes the chronic phase as usually beginning around 12 to 18 months after symptoms first appear.

The condition does not always require treatment. Treatment depends on pain, the degree of curvature, erectile function, and whether sexual activity is affected.

Current European guidance continues to support assessment based on the man's symptoms, penile deformity, erectile function, and disease stage rather than treating every case in the same way.

Treatment Options

Treatment depends on your symptoms and how stable the condition is. Some men need only observation. Others may benefit from medical treatment.

Options can include:

• Pain relief during the painful stage

• Penile traction or other mechanical treatment in selected cases

• Injections into the plaque in appropriate patients

• Surgery for severe or stable deformity

• A penile implant when significant erectile dysfunction is also present

There is no single treatment that works for every man. Oral medicines have not been shown to reliably straighten the penis. The right option should be discussed with a urologist.

Final Takeaway

Peyronie’s disease is caused by scar tissue inside the penis. It can lead to a new curve, or erection problems.

Knowing what is normal can help you notice a real change. A small natural curve is common. A new or worsening curve, especially with pain or a hard plaque, should be checked by a urologist.

Frequently Asked Questions

What is Peyronie's disease caused by?

The exact cause is not fully known. Repeated minor injury or trauma may trigger abnormal scar formation in some men. Family history, age, connective-tissue conditions, autoimmune conditions, and some other health factors may also increase risk.

What does Peyronie's disease look like compared with a normal curved penis?

A normal penis can have some curvature, especially when the curve has been present for a long time. Peyronie’s disease is more likely when there is a new or changing curve, a hard plaque, pain, shortening, indentation, or an hourglass-like shape.

Can Peyronie's disease go away without treatment?

It can improve in some men, but complete spontaneous resolution is uncommon. Pain often decreases over time, while curvature and shortening may remain. A doctor can help determine whether monitoring or treatment is appropriate.

Is Peyronie's disease dangerous?

Peyronie’s disease is not cancer, and the plaque itself is benign. However, it can cause painful erections, erectile dysfunction, difficulty with intercourse, penile shortening, and emotional or relationship stress. A urologist can assess the condition and discuss treatment when needed.
