In the differential diagnosis of men with erectile dysfunction (ED) it is important to know whether or not the male patient is potentially sexually potent, i.e. whether or not a (semi) rigid erection, presumably sufficient for intercourse, can occur. Preferably such information is gathered by a thorough history taking, and, if necessary, followed by non-invasive investigations. Penile erection is the result of a neurovascular response to a complex set of visual, tactile and psychogenic stimuli. It is thought to result from increased arterial flow through the cavernous vessels "With subsequent sinusoidal engorgement and decreased venous return. Anatomic innervation is derived from both sympathetic and parasympathetic chains at the posterolateral surface of the prostate.
