Penile curvature is an anomaly of the male genital organ characterized
by axial or lateral deviation during erection. It may be congenital o
r acquired. Ventral curvature of the penis, common in the embryo, may
persist in 31% of permature babies and tends to self-correction in the
early months of life. Most cases present with moderate curvatures wit
hout functional problems. Some may present with marked curvatures in t
he early years of life, causing major psychological and functional pro
blems. The authors present their experience in 16 consecutive prepuber
tal cases treated surgically and propose a new classification based on
embryological considerations.
