According to a new study, men with erectile dysfunction should be tested for testosterone deficiency and metabolic syndrome, because both the conditions commonly occur together.
"Erectile dysfunction is a portal into men's health," said the study's senior author, Aksam Yassin, MD, PhD, of the Clinic for Urology and Andrology of the Segeberger Clinics in Norderstedt, Germany.
"It is becoming clear that obesity, diabetes, high blood pressure, cholesterol problems and erectile difficulties are intertwined, and a common denominator is testosterone deficiency," Yassin added.
Yassin's research, performed with scientists from The Netherlands, Germany and the United Arab Emirates, aimed to determine in men with erectile dysfunction (ED) the prevalence of hypogonadism, the scientific term for testosterone deficiency.
Over a two-year period the investigators studied 771 patients who sought treatment for ED. Their average age was 56. The patients received a comprehensive screening for low testosterone and indicators of the metabolic syndrome, a cluster of risk factors that increase the chances of developing heart and vascular disease and type 2 diabetes.
Having three of the following five risk factors establishes the diagnosis of this syndrome: increased waist circumference (abdominal fat), low HDL ("good") cholesterol, high triglycerides (fats in the blood), high blood pressure, and high blood sugar.
Among the 771 men, 18.3 percent of the men (141 men) had testosterone deficiency, which had previously been undetected, the authors found.
The prevalence of hypogonadism in the general population of men age 45 and older is about 12 percent, Yassin said.
