[Anatomy of the anterior male perineum]

The central nucleus of the perineum. Having carefully studied the anatomy of the central nucleus of the perineum on 27 male pelvises, the authors discuss the fibromuscular nature of this structure which extends from the peritoneal cul-de-sac to the perineal fascia, between urogenital pathways in front and digestive pathways in back. The connections to all the pelvic-perineal organs are discussed. The middle perineal adoneurosis. A personal conception. The study of twenty seven male perineums has permitted the authors to formulate a personal conception of the anatomy of the middle perineal aponeurosis. It is made up of adjoining structures organized in front and in back of the urethrae; above all it includes a smooth fibromuscular part in back of this canal, whereas in front, it behaves as a vessel-carrying sheath, where the dorsal pack of the penis and the Santorini plexus pass.
