process is produced by scar formation in the fibrous covering of the erectile bodies of the penis. Men may or may not feel tenderness, a lump, or an area of scarring {plaque) in the shaft of the penis. Occasionally, this condition is also associated with pain, and, in some cases, erections and stress on the penis can exacerbate the pain. Many patients with Peyronie’s disease suffer psychological trauma, may experience difficulty with sexual intercourse, and may also suffer from erectile dysfunction. Those who suffer from erectile dysfunction, however, may not notice these symptoms. Peyronie’s disease occurs more often in men between the ages of 50 and 70, although younger men are not immune. Its’ accurate incidence is unknown, but it is not rare. Studies show that about three percent of men over the age of 40 have scar tissue in their penis labeled as Peyronie’s disease. However, only a minority of these men have significant enough scarring, curvature, erectile dysfunction, or penile shortening to require medical attention.
