Peyronie's disease

Peyronie's (pay-roe-NEEZ) disease is the development of fibrous scar tissue inside the penis that causes curved, painful erections.

Men's penises vary in shape and size. Having a curved erection is common and isn't necessarily a cause for concern. However, in some men, Peyronie's disease causes a significant bend or pain.

This can prevent a man from having sex or might make it difficult to get or maintain an erection (erectile dysfunction). For many men, Peyronie's disease also causes stress and anxiety.

In a small percentage of men, Peyronie's disease goes away on its own. But in most cases, it will remain stable or worsen. Treatment might be needed if the curvature is severe enough that it prevents successful sexual intercourse.

Symptoms Causes Risk factors Complications

Peyronie's disease signs and symptoms might appear suddenly or develop gradually. The most common signs and symptoms include:

  • Scar tissue. The scar tissue (plaques) associated with Peyronie's disease can be felt under the skin of the penis as flat lumps or a band of hard tissue.
  • A significant bend to the penis. Your penis might be curved upward, downward or bent to one side. In some cases, the erect penis might have narrowing, indentations or an hourglass appearance, with a tight, narrow band around the shaft.
  • Erection problems. Peyronie's disease might cause problems getting or maintaining an erection (erectile dysfunction).
  • Shortening of the penis. Your penis might become shorter as a result of Peyronie's disease.
  • Pain. You might have penile pain, with or without an erection.

The curvature associated with Peyronie's disease might gradually worsen. At some point, however, it stabilizes in the majority of men.

In most men, pain during erections improves within one to two years, but the scar tissue and curvature often remain. For a few men, both the curvature and pain associated with Peyronie's disease improve without treatment.

When to see a doctor

See your doctor if pain or curvature of your penis prevents you from having sex or causes you anxiety.
