Lifestyle and Metabolic Effects on Erectile, Vascular Health
Table 1 summarizes the lifestyle and metabolic factors having positive and negative effects on ED and/or vascular NO. In some cases, randomized controlled trials are not possible, such as with smoking, excessive alcohol or hyperhomocysteinemia, but others, such as the effect of omega-3 fatty acids on ED, are entirely possible and are conspicuously lacking. Further randomized trials are needed, including various combinations of the listed interventions, such as the favorable effects on ED of combining testosterone and sildenafil, or of the Mediterranean diet, which increases intakes of omega-3's, antioxidants and folic acid.
