Webtraction is under a-adrenergic control. Penile erection is triggered by one of two events: direct stimulation of the genitalia (reflexogenic erection) or via stimuli from the brain (psychogenic erection). The primary control of reflexogenic erection is centred in the parasympathetic centre of the spinal cord (S2-S4). Webnon-adrenergic non-cholinergic nerves (NANC), which in turn promotes vascular and cavernosal relaxation, leading to an increase in blood flow and intracavernosal pressure resulting in erection (Figure 1). Although severa l vasodilators have been implicated in this process, nitric oxide (NO) still is the main vasodilator involved 18-19. In the ...
