Neurogenic Sexual Dysfunction in Men and Women

  title={Neurogenic Sexual Dysfunction in Men and Women},
  author={Kazem M Azadzoi and Mike B. Siroky},
The penis is innervated by parasympathetic nerves arising from the second to fourth sacral cord segments (pelvic nerves) that ultimately become the cavernosal nerves. Sympathetic innervation, via the hypogastric nerve and pelvic plexus, causes detumescence but may also serve as an alternate erectile pathway. Somatic (sensory and motor) nerves reach the penis via the pudendal nerve. In the female, the genital organs have a complex innervation that is not well understood. The pelvic nerves appear… 

Neurogenne zaburzenia erekcji pochodzenia rdzeniowego Neurogenic erictile dysfunction caused by diseases and damages of spinal cord

Under the diseases and damages of spinal cord comes to series of sexual Dysfunctions including erectile dysfunctions, where the inability to achive and/or keep penile erection makes impossible to have satisfactional sexual life.

Male Sexual Dysfunction

Although sexual dysfunction problems are more common in women than in men, almost everywhere in the world, men are more likely to seek help. Most rely on their own strength, search for help over the

Disfunzione erettile di origine neurologica

La disfunzione erettile (DE), dizione che ha ormai sostituito il termine “impotenza”, e per definizione “l’incapacita a iniziare e mantenere una erezione sufficiente per un rapporto sessuale



Sympathetic pathways and adrenergic innervation of the penis

The sympathetic nervous system is important for penile function: it mediates detumescence and may contribute to the maintenance of the penis in a non-erect state and the role of interactions between different transmitters and mediators in the regulation of contraction and relaxation of CC and penile vessels needs further study.

Central noradrenergic control of penile erection

The most robust evidence is that central inhibition of alpha-2 adrenoceptors facilitates sexual function and pharmacological experiments suggest a modulatory role for noradrenaline in the control of penile erection either in the brain or in the spinal cord.

Spinal control of penile erection

SummarySmooth muscle relaxation of penile arteries, the corpus cavernosum, and the corpus spongiosum, leading to penile erection, results from parasympathetic neural pathway activation and, likely,

Erectile mechanism in paraplegia

Peripheral nerves mediating penile erection in the rat.

Principal mechanisms controlling penile retraction and protrusion in rabbits.

The effects on penile volume of nerve stimulations and drugs injected into the systemic circulation were studied plethysmographically and two vasodilator paths were found, probably having mainly non-cholinergic postganglionic neurons and operating quite effectively at low frequencies.

Perineal musculature and its innervation by spinal motoneurons in the male rabbit: effects of testosterone.

Striated muscles in the perineum, which include the ischiocavernosus (IC), bulbocavernosus (BC), and levator ani (LA), were identified in an attempt to understand motor regulation of penile erection

Erectile response to hypothalamic stimulation in rats: role of peripheral nerves.

It is proposed that sympathetic fibers running in the paravertebral sympathetic chain are responsible for vasoconstriction of nonpenile areas to divert blood to the penis, allowing the dramatic increase of penile arterial inflow required for erection.
