Which nerve is responsible for erectile dysfunction?
The dorsal penile nerve (pudendal nerve) is responsible for reflex erections. Damage to the pudendal nerves (that is, Alcock syndrome) leads to erectile dysfunction.
Are erections sympathetic?
It was concluded that subsidence and suppression of erection is a sympathetic function. Previous studies have shown that the neurophysiology of erection can be explained by 3 major inhibitory (sympathetic).
What causes Detumescence?
Stimulation of the pelvic plexus and the cavernous nerves induces erection, whereas stimulation of the sympathetic trunk causes detumescence. This clearly implies that the sacral parasympathetic input is responsible for tumescence and the thoracolumbar sympathetic pathway is responsible for detumescence.
What causes erection?
During sexual arousal, nerve messages begin to stimulate the penis. Impulses from the brain and local nerves cause the muscles of the corpora cavernosa to relax, allowing blood to flow in and fill the open spaces. The blood creates pressure in the corpora cavernosa, making the penis expand and creating an erection.
What is the best treatment for erectile dysfunction?
Oral drugs or pills known as phosphodiesterase type-5 inhibitors are most often prescribed in the U.S. for ED (Viagra, Cialis, Levitra, Stendra) Testosterone Therapy (when low testosterone is detected in blood testing) Penile Injections (ICI, intracavernosal Alprostadil) Intraurethral medication (IU, Alprostadil)
What nerve controls genitals?
The pudendal nerve is crucial for sensation and function in your pelvic region, including the genitals and anus. This nerve is part of your peripheral nervous system. Peripheral nerves send signals from your central nervous system (brain and spine) to your limbs and certain organs.

Can L5 cause ED?
Conclusion: A syndrome with perianal sensory deficit, paralysis of the sphincter, and sexual dysfunction may occur in patients with lumbar L5-S1 disc disease. The improvement of perianal sensory deficit after surgery was counteracted by a trend toward disturbed sexual function.
