Learn what causes curvature of the penis and how it is treated here. Not all men have a straight penis, but that doesn't mean it is curved enough to be considered a true curvature. True curvature of the penis happens during an erection, and can involve narrowing of the penis during an erection, and painful erections.
Peyronie's disease. This disease affects men who are over 40 years old. In this disease, scar tissue forms under the layer of skin on the penis. This scar tissue causes the penis to curve during an erection because it is bound to the skin. Peyronie's disease generally occurs after an injury to the penis. Forceful or vigorous sexual intercourse can cause the shaft to bend, and cause scar tissue to form. Some procedures such as catheter placement or prostate removal can also cause injury which makes this scar tissue form. Deficiency in Vitamin E has also been linked to this disease. Diseases such as diabetes can also cause Peyronie's disease because diabetes can damage the blood vessels within the penis. The high blood pressure medication propanolol has a rare side effect of Peyronie's disease.
Dupuytren's contracure. This disease is diagnosed by a thick cord visible on one or both palms of the hands. Although this is a common disorder in men over fifty years old, not all men with this disorder develop curvature of the penis. Dupuytren's contracture may be inherited.
Hypospadias. This abnormality is seen in newborns and causes curvature of the penis. This condition does not affect adult men.
Treatment options. Curvature of the penis can be treated with oral medications, radiation therapy, and surgery. Surgical procedures are generally done if the erections are causing pain. Surgical corrections carry the risk of impotence.
