Congenital penile curvature (CPC) is a rare condition, with a reported incidence of < 1%, although some studies have reported higher prevalence rates of 4-10%.
Congenital penile curvature results from disproportionate development of the internal structures inside the penis (tunica albuginea of the corporal bodies). In most cases, the penile bend is downwards (ventral), but it can also be sideward (lateral) and, more rarely, dorsal (penis bent up).
