Peyronie's disease in the male causes:
A. Balanitis of the penis
B. Cryptorchidism
C. Curvature of the penis
D. Fracture of the penis
ANS: C
Although the precise cause of Peyronie's disease is not known, current belief regarding its etiology is that plaque formation results after disordered wound healing, often with calcium deposition in the plaque (Pendleton & Wang 2013). During regular sexual activity, susceptible patients may suffer nonpainful minor trauma to the penis that leads to a decrease in the elasticity of the tissue and fibroblast formation, eventually resulting in plaque. The plaque is present in the tunica albuginea of the corpora cavernosa, which leads to shortening and curvature of the shaft of the penis. The resulting curvature can be in any direction: lateral, ventral, or dorsal.
