Penis Disorders (cont.)

What is Peyronie's disease?

Peyronie's disease is a condition in which a plaque, or hard lump, forms on the penis. The plaque may develop on the upper (more common) or lower side of the penis, in the layers that contain erectile tissue. The plaque often begins as a localized area of irritation and swelling (inflammation), and can develop into a hardened scar. The scarring reduces the elasticity of the penis in the area affected.

Peyronie's disease can occur in a mild form that heals without treatment in 6 -18 months. In these cases, the problem does not progress past the inflammation phase. In severe cases, the disease can be permanent. The hardened plaque reduces flexibility, causing pain and forcing the penis to bend or arc during erection.

In addition to the bending of the penis, Peyronie's disease can cause general pain as well as painful erections. It also can cause emotional distress, and affect a man's desire and ability to function during sex.

What causes Peyronie's disease?

The exact cause of Peyronie's disease is unknown. In people whose disease develops quickly, lasts a short time, and goes away without treatment, the likely cause is trauma (hitting or bending) that causes bleeding inside the penis. However, in some people, Peyronie's disease develops slowly and is severe enough to require surgical treatment. Other possible causes of Peyronie's disease include:

  • Vasculitis: This is an inflammation of blood or lymphatic vessels. This inflammation can lead to the formation of scar tissue.
  • Connective tissue disorders: According to the National Institutes of Health, about 30% of men with Peyronie's disease also develop disorders that affect the connective tissue in other parts of their bodies, such as the hands and feet. These conditions generally cause a thickening or hardening of the connective tissue. Connective tissue is specialized tissue -- such as cartilage, bone, and skin -- that acts to support other body tissues.
  • Heredity: Some studies suggest that a man who has a relative with Peyronie's disease is at greater risk for developing the disease himself.
