Congenital penile curvature presents penile bending of a normally formed penis due to corporal disproportion. Besides this isolated penile curvature, penile bending can appear as a part of hypospadias or epispadias anomalies (discussed elsewhere). Direction of penile curvature can be ventral, dorsal, lateral or in several planes (corkscrew penis). The curvature is usually most obvious during erection, but resistance to straightening is often apparent in the flaccid state as well.
