Male sexual response is controlled by a series of neurally mediated phenomena regulating libido, motivation, arousal and genital responses such as penile erection and ejaculation. These neural events that occur in a hormonally defined milieu involve different neurophysiological, neurochemical, and neuropsychological parameters controlled by central mechanisms, spinal reflexes and peripheral nervous system. Epidemiologic studies have suggested the high prevalence of male sexual dysfunction worldwide with significant impact on the quality of life of patients suffering from this problem.

The male sexual response cycle consists of excitement, plateau, orgasm, and resolution. The initial event, penile erection, is produced by arteriolar dilatation and increased blood flow to the erectile tissue of the penis. Erection is a reflex response initiated by visual, olfactory, or imaginative stimuli impinging upon supraspinal centers or by genital stimulation that in turn activates spinal reflex mechanisms. Sacral parasympathetic and thoracolumbar sympathetic nerves provide the efferent vasodilator input to the penis.

The management of erectile dysfunction ED has changed dramatically in recent years, as advances in molecular biology have given us a better understanding of the erectile process as well as the pathophysiology of erectile disorders. Until relatively recently, however, most research in ED focused on peripheral neurophysiology and on the local tissues of the penis, leading to the development of highly effective treatments such as penile injections and sildenafil. There has, however, been growing interest in the role of the central nervous system CNS in the control of erectile function, and researchers have begun to develop medications that target these central mechanisms.
