DefinitionBy Mayo Clinic staff
Peyronie's (pa-ro-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, and 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 may make it difficult to get or maintain an erection (erectile dysfunction). For many men, Peyronie's disease also causes stress and anxiety.
In some cases, medications may help. Surgery to treat Peyronie's disease is generally only recommended if the curvature and pain are severe enough to prevent sexual intercourse.
