Most patients with Peyronie's disease can continue to function sexually with the curvature in the penis. However, a third of men with Peyronie's have pain with their erections, and a few with the condition become impotent. In some cases, the head of the penis does not fill with blood. Many patients complain not only about the curvature of the erection but also about the loss of length and girth. These are all results of the inelastic tissue and lack of distention. In very rare cases, there can be patients with greater penile distortion that results in unsatisfactory sexual intercourse.
