Erectile function improves in men with hypercholesterolemia as the only risk factor for ED when treated with atorvastatin. Treating hypercholesterolemia may improve ED, while promoting primary cardiac prevention.

Secondary hypogonadism is more common than primary gonadal failure and is seen in chronic and acute illnesses. Although testosterone has a role in erections, its importance in erectile dysfunction (ED) has been controversial. Hypogonadism produced by functional suppression of pituitary gonadotropins has been shown to correct with clomiphene citrate, but with a modest effect on sexual function. We wondered if longer treatment would produce improved results. A total of 178 men with secondary hypogonadism and ED received clomiphene citrate for 4 months. Sexual function improved in 75%, with no change in 25%, while significant increases in luteinizing hormone (Po0.001) and free testosterone (Po0.001) occurred in all patients. Multivariable analysis showed that responses decreased significantly with aging (Po0.05). Decreased responses also occurred in men with diabetes, hypertension, coronary artery disease, and multiple medication use. Since these conditions are more prevalent with aging, chronic disease may be a more important determinant of sexual dysfunction. Men with anxiety-related disorders responded better to normalization of testosterone. Assessment of androgen status should be accomplished in all men with ED. For those with lower than normal age-matched levels of testosterone treatment directed at normalizing testosterone with clomiphene citrate is a viable alternative to giving androgen supplements.

Introduction Advanced age in men is accompanied by an increased prevalence of cardiovascular disease (CVD) and erectile dysfunction (ED). Prior studies revealed that 56% of an ED population have asymptomatic myocardial ischemia, 75% of men with CAD have symptoms of ED, and 91% of our ED patients have cardiovascular risks. Aim Because metabolic syndrome (MS) and insulin resistance (IR) are both predictors of CVD, we wished to evaluate these parameters in our population. Methods Our men (N = 154) were evaluated for multiple cardiovascular risk factors and graded on severity of ED. The severity of ED was evaluated by the Sexual Health Inventory for Men (SHIM) questionnaire. The prevalence of MS was determined by NCEP/ATP III criteria. Insulin resistance was measured by QUICKI. Main Outcome Measures Bivariate associations among total cholesterol/high-density lipoprotein (HDL), triglyceride/HDL, and Quantitative Insulin Sensitivity Check Index (QUICKI) were compared. Chi-square analysis was used to evaluate the relation between the presence and severity of IR with the severity of ED. Results The total cholesterol/HDL ratio was moderately and negatively correlated with QUICKI (r = −0.33; P < 0.01) and similarly for the triglyceride/HDL ratio (r = −0.32; P < 0.01). Metabolic syndrome was present in 43% of our ED population as opposed to 24% in a matched patient population. Approximately 79.2% of our total population had IR and 73.3% of the nondiabetic portion (N = 120) had IR, compared to 26% in a general population study. Metabolic syndrome (P = 0.01), IR (P = 0.01), and fasting blood sugar (FBS) >110 mg/dL (P = 0.01) correlated positively and moderately with increasing severity of ED by SHIM score. Conclusion Men with ED have a high incidence of MS and IR. Early detection of metabolic disease in patients with ED may be a gateway to the reduction endothelial dysfunction in younger men with increased cardiovascular risk but who present for treatment of ED alone.
