A case of painful erections after pelvic surgery.

There are no data in the literature on the incidence or treatment of posttraumatic painful erections not related to surgery of the genital system. A case of a 27-year-old man with painful erections after fracturing his sacral, pubic, and ischial bones in a motorbike accident is presented. His painful erections occurred in coitus, masturbation, and morning tumescence. No penile or neural pathology was found to account for the pain. He was treated with diazepam 2 mg before masturbation for 2 weeks, when the symptoms disappeared. The possible causes of the problem and its resolution are discussed.
