Erectile dysfunction refers to an inability to either produce or maintain an erection that is firm enough to have sexual intercourse. Although erectile dysfunction is thought to be relatively common, its exact prevalence has been difficult to ascertain; studies have produced a wide range of results. A group of researchers recently set out to examine the prevalence of erectile dysfunction. They also assessed the evidence of its association with cardiovascular disease and mortality. Understanding the size and scope of erectile dysfunction is more important than ever. To investigate, the scientists took data from earlier studies. In total, they identified 41 relevant studies that examined the prevalence of erectile dysfunction or its role in other conditions. The researchers found an incredible variety; prevalence rates ranged from just 3% to 76.5%. When the scientists looked for links between erectile dysfunction and cardiovascular disease, they found a "wealth of evidence. They observed increased prevalence and incidence in a number of conditions, including myocardial infarction, ischemic heart disease, hypertension, stroke, angina, arteriosclerosis, and peripheral vascular disease. The authors conclude that "The global prevalence of [erectile dysfunction] is high and represents a significant burden on the [quality of life] of men and their partners. They also believe that "Physicians should consider screening for [erectile dysfunction] in at-risk patients, as information may not be volunteered. (Source: www.medicalnewstoday.com
