Clinical Neuroanatomy and Neurotransmitter-Mediated Regulation of Penile Erection
Erectile dysfunction (ED) has an adverse impact on men's quality of life. Penile erection, which is regulated by nerves that are innervated into the erectile tissue, can be affected by functional or anatomical trauma of the perineal region, including specific structures of the penis, causing ED. Penile erection is neurologically controlled by the autonomic nervous system. Therefore, it is of ut...
متن کاملPenile Erection
Hemodynamic Aspects Penile erection and detumescence are primari ly controlled by hemodynamic events. Increased arterial inflow appears to be of primary importance; the contribution of increased venous resistance to the production of penile erection remains controversial. Furthermore, our understanding of precise anatomic details ( including “shunts”) and the neural control of vascular events i...
متن کاملPharmacology of penile erection.
Erection is basically a spinal reflex that can be initiated by recruitment of penile afferents, but also by visual, olfactory, and imaginary stimuli. The reflex involves both autonomic and somatic efferents and is modulated by supraspinal influences. Several central transmitters involved in the erectile control have been identified. Dopamine, acetylcholine, nitric oxide (NO), and peptides, such...
متن کاملIntraoperative penile erection.
OBJECTIVE Penile erection following epidural anesthesia is an infrequent occurrence of unclear etioogy. It is very troublesome to perform the procedure during penile erection and attempting it leads to various complications. Three such cases are reported herein. The literature on the pathophysiology and management of intraoperative penile erection is discussed. METHODS Eighteen hundred patien...
متن کاملCalcitonin gene-related peptide: possibly neurotransmitter contributes to penile erection in monkeys.
The distribution of calcitonin gene-related peptide (CGRP) immunoreactivity in the cavernous tissue and the erectile response to intracavernous injection of CGRP was investigated in 7 monkeys. Intracavernous CGRP increased cavernous arterial flow and induced cavernous smooth muscle relaxation and venous outflow occlusion. Intracavernous injection of CGRP antibody did not significantly change th...
