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 six to 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.
