Example of penis deformation from side A certain degree of curvature of the penis is considered normal, as many people are born with this benign condition, commonly referred to as congenital curvature. The disease may cause pain; hardened, big, cord-like lesions (scar tissue known as "plaques"); or abnormal curvature of the penis when erect due to chronic inflammation of the tunica albuginea (CITA). Although the popular conception of<unk>  is that it always involves curvature of the penis, the scar tissue sometimes causes divots or indentations rather than curvature. The condition may also make sexual intercourse painful and/or difficult, though it is unclear whether some men report satisfactory or unsatisfactory intercourse in spite of the disorder. The disorder is confined to the penis, although a substantial number of men with<unk> 's exhibit concurrent connective tissue disorders in the hand, and to a lesser degree, in the feet. About 30 percent of men with<unk>  develop fibrosis in other elastic tissues of the body, such as on the hand or foot, including Dupuytren's contracture of the hand. An increased incidence in genetically related males suggests a genetic component. It can affect men of any race and age. Psychosocial<unk>  can also have psychological effects. While most men will continue to be able to have sexual relations, they are likely to experience some degree of erectile dysfunction. It is not uncommon to exhibit depression or withdrawal from their sexual partners.
