Both Peyronie’s Disease and congenital penile curvature can be found in adolescents and young adults and therefore the age of onset is not a good criterion to distinguish between the two conditions. However, in patients with congenital penile curvature there is no palpable lump, which is instead indicative of Peyronie’s Disease.  Also, while most congenital curvatures are ventral, in most patients with Peyronie’s Disease the penis bends upward. Waist deformities are also absent in patients with congenital curvature, which tend to be more gentle and harmonic than the one of patients with Peyronie’s Disease.
While erectile dysfunction is a common finding in patients with Peyronie’s Disease, most patients with congenital penile curvature have adequate erections, as there is no association between cardiovascular risk factors and congenital penile curvature. To render the situation more confusing, some of the patients with congenital penile curvature may eventually develop Peyronie’s Disease later in life and therefore both conditions may coexist.
