title: Cardiovascular disease and sleep-related erections.
abstract: Sexual difficulties are highly prevalent in male patients with cardiovascular diseases, such as hypertension, atherosclerosis, and hypercholesterolemia. Recently, several studies have been conducted on the effects of cardiovascular diseases, as well as associated drug and nondrug treatments, on nocturnal penile tumescence (NPT) and other measures of sexual function. Although an overall trend has been observed toward decreased NPT in patients with chronic hypertension and other cardiovascular conditions, design and methodological difficulties have been noted in most studies, and results have been generally, inconclusive. Similarly, antihypertensive drugs such as beta-blockers and diuretics have been associated with diminished NPT in several studies, although methodological problems have again been noted. Furthermore, the mechanism of action of antihypertensive drugs on sleep-related erections has not been determined. Most recently, a positive effect of cholesterol-lowering drugs (pravastatin, lovastatin) on NPT has been observed in middle-aged males with chronic hypercholesterolemia. Additional studies of the effects of cardiovascular disease on NPT and other measures of sexual function are needed.
