title: [Neurophysiology of perineal pain].
abstract: Perineal pains are based on two principal mechanisms: excess of nociception and desafferentation. The pain is psychogenic when none these mechanisms is found. Chronicization depends on first primary and secondary hyperalgesia and is sustained by sympathic and motor reflexs, and second nevrotic characters and even psychiatric pathology which give a painful experience of life.
