Peyronie's disease is a condition that causes curved and painful erections. Your penis may also be shorter during erections or look different than it used to. This happens when scar tissue forms in the tissues under the skin of the penis.
Not all curved erections are cause for concern, but Peyronie's disease can cause a severe curve or pain. In severe cases, it may prevent you from having sex or lead to erectile dysfunction.
The most common cause of Peyronie's disease is repeated injury to the penis, which leads to scar tissue forming. Other risk factors include a family history of Peyronie's disease, connective tissue diseases, and age. For some people, the exact cause is unknown.
Potential treatments for Peyronie's disease include traction therapy, medications, and surgery to straighten the penis.
