Contrôle nerveux central de l’érection

Système nerveux du pénis

Metrics details Abstract Local mechanisms causing penile erection and detumescence result from variation in tone of vascular and trabecular smooth muscles and in a lesser part of striated muscles around the crura penis.

All these events are neurally mediated. We reviewed human and animal data concerning the functional peripheral neuroanatorny of erection.

General organization of peripheral nervous system is recalled.

Somatic efferents of the pudendal nerve, originating in the sacral spinal cord, innervate the striated musculature of the perineum. Somatic afferents of the penis are conveyed by the dorsal penile nerve, a branch of the pudendal nerve.

Afferent terminations project into the spinal cord, their role is discussed. Parasympathetic pathways are involved in the reflexogenic erections.

Sympathetic pathways destinated to the erectile structures are more complex. They are issued from thoracolumbar spinal cord and travel through the hypogastric nerve or the lumbosacral sympathetic chain.

Sympathetic fibers originating in the sacral sympathetic chain are present in both pelvic and pudendal nerves. Inhibitory role on the erection of the sympathetic nervous system is well-known, it could be also responsible for psychogenic erections. Parasympathetic and sympathetic fibees are mixed in the pelvic plexus and the cavernous nerves which are described. Relations between the four sets of peripheral nerves somatic efferents, penile afferents, thoracolumbar sympathetic sacral parasympathetic and sympathetic are discussed.
