Peyronie disease (PD) is a growth of scar tissue under the skin of the penis. It causes a bend in the penis.


The exact cause of PD is not clear. Injury to the area may play a role. A problem with the immune system may play a role for some.

Risk Factors

Things that may increase the risk of PD include:

  • Trauma to penis
  • Others in family who have PD
  • Smoking or other tobacco use
  • Frequent alcohol use
  • Surgery in the area such as prostatectomy
  • Diabetes mellitus


Symptoms may develop quickly or slowly and may include:

  • Hard lumps on penis
  • Bend in penis—may only be apparent during erection
  • Change in penis shape which may include a dent, or change in size
  • Pain during erection
  • Sex being painful or impossible

Pain may decrease over time. Symptoms can lead to problems having sex or erectile dysfunction (ED).


The doctor will ask about your symptoms and past. A physical exam will be done. PD is often diagnosed based on symptoms and exam.


PD does not always need treatment. When needed, treatment can help to ease pain and straighten the penis. It may also ease problems with sexual performance. Treatment choices are:


  • Pills—may slow growth of scar tissue
  • Injections—may decrease scar tissue and easy curve of penis
  • Gels—applied to penis may reduce curve, scarring, and pain with erection
  • Coenzyme Q10 or Vitamin E plus colchicine—may help ease curve in early stages


This may be chosen if other treatments have not helped. It may be done if sex is painful or impossible because of the curve. Surgery may delayed until curve is no longer changing. Choices may include:

  • Removing scar tissue and replacing with graft from other area.
  • Pinching or tightening penis on opposite side. It will help to straighten the penis. It may shorten the penis.
  • Implanting a device. It can assist an erection or straighten it out.


There are no steps to prevent PD.
