Dietary factors in erectile dysfunction.

The role of dietary factors in erectile dysfunction (ED) has never been addressed. In the present case-control study, we investigated the relation of the Mediterranean diet with ED. A total of 100 men with ED were compared with 100 age-matched men without ED. A scale indicating the degree of adherence to the Mediterranean diet was constructed: the total Mediterranean diet score ranged from 0 (minimal adherence to the Mediterranean diet) to 9 (maximal adherence). The percentage of physical inactivity was greater in the ED group (35 vs 19%, P=0.04), whereas the diet score was lower (4.7+/-0.5 vs 5.4+/-0.5, P<0.01), indicating a reduced adherence to the Mediterranean diet. In analyses adjusted for the prevalence of associated risk factors (hypertension, hypercholesterolemia), body mass index, waist, physical inactivity and total energy intake, the intake of fruits and nuts, and the ratio of monounsaturated lipids to saturated lipids remained the only individual measures associated with ED. In conclusion, the results of the present study show that dietary factors may be important in the development of ED: adoption of healthy diets would hopefully help preventing ED.

Effects of surgical menopause and estrogen replacement therapy on atrio-ventricular conduction and ventricular repolarization.

OBJECTIVE: To evaluate the effect of surgical menopause and estrogen replacement therapy on atrio-ventricular conduction and ventricular repolarization in women. METHODS: In a prospective, randomized, double-blind, placebo-controlled clinical trial 50 women underwent hystero-salpingo-oophorectomy. Twenty-five women were treated with 50 microg/die of transdermal estradiol and the other 25 were treated with placebo patches. The duration of the treatment was 12 cycles. Before surgery and after 12 cycles of treatment, a standard electrocardiogram was performed to evaluate atrio-ventricular conduction time and cardiac repolarization time. RESULTS: No significant variations in atrio-ventricuar conduction time and cardiac repolarization time were detected between the two groups at entry, nor was there any difference in both groups after 12 cycles of treatment with transdermal estradiol. CONCLUSIONS: Surgical menopause and estrogen replacement therapy do not modify atrio-ventricular conduction and ventricular repolarization in women.

Erectile dysfunction associates with endothelial dysfunction and raised proinflammatory cytokine levels in obese men.

Erectile and endothelial dysfunction may have some shared pathways through a defect in nitric oxide activity. We evaluated associations between erectile function, endothelial function and markers of systemic vascular inflammation in 80 obese men, aged 35-55 yr, divided into two equal groups according to the presence/absence of erectile dysfunction. Compared with non-obese age-matched men [no.=50, body mass index (BMI)=24 +/- 1], obese men (all) had impaired indices of endothelial function as suggested by the reduced mean blood pressure and platelet aggregation responses to L-arginine, and higher circulating concentrations of the proinflammatory cytokines interleukin-6 (IL-6), interleukin-8 (IL-8), interleukin-18 (IL-18), as well as C-reactive protein (CRP). The mean erectile function score was 14 +/- 4 (range 7-19) in obese men with erectile dysfunction and 23.5 +/- 1 (range 22-25) in obese men without erectile dysfunction. Endothelial function showed a greater impairment in impotent obese men as compared with potent obese men. The mean blood pressure and platelet aggregation decreases following L-arginine were -1.5 +/- 1.1 mmHg and -1.1 +/- 1.2%, respectively, in obese men with erectile dysfunction, and -3.4 +/- 1.2 mmHg and -5.6 +/- 2.1%, respectively, in obese men without erectile dysfunction (p < 0.01). Circulating CRP levels were significantly higher in obese men with erectile dysfunction as compared with obese men without erectile dysfunction (p < 0.05). Erectile function score was positively associated with mean blood pressure responses to L-arginine and negatively associated with BMI, waist-to-hip ratio (WHR), and CRR Erectile and endothelial dysfunction associate in obese men and may contribute to their raised cardiovascular risk through impaired nitric oxide availability elicited by a low-grade inflammatory state.
