Objectives: The knowledge of penile anatomy is basic to perform a proper diagnosis and direct the most adequate treatment of the various diseases that may appear: urethral stenosis, erectile dysfunction, congenital or acquired penile curvature, etc.; being its anatomical knowledge essential for a proper surgical management. The penis is the male organ involved in both voiding and sexual functions: the body of the penis is composed by three erectile bodies, (i.e the deep structures!: the corpora cavernosa and the corpus spongiosum, this last surrounding and covering the urethra. Buck's fascia is in relation to the deep structures of the penis. The superficial fascia, dartos, is made up from a more areolar tissue and is in relation to skin and vessels. The vascularization of the deep structures comes from the common penile artery, a branch of the internal pudendal artery. Penile blood drains through three venous systems: superficial, intermediate and deep systems. Pudendal nerves are in charge of the sensitive and motor somatic innervations. Cavernosal nerves are a combination of parasympathetic and sympathetic afferent fibers, corresponding to the nerves of the autonomic system of the penis.

Keywords : Penile anatomy; Erectile dysfunction.
