Lycopene is one of those phytonutrients that is good for circulation and good for sexual issues. Lycopene is found in deep red fruits like tomatoes and pink grapefruits. Some studies show that lycopene may be absorbed best when mixed with oily foods like avocados and olive oil. So you might want to make yourself an ED-fighting salad. Research also shows that antioxidants like lycopene help fight male infertility and prostate cancer.
These drugs facilitate erection by inhibiting the PDE5 enzyme, by blocking the degradation of cyclic guanosine monophosphate (cGMP) in the cavernous smooth muscles. This inhibition results in the prolonged activity of cGMP, which further decreases intracellular calcium concentrations, maintains smooth muscle relaxation and, hence, results in rigid penile erections.

By far the most common cause of ED is vascular dysfunction. When the arteries that supply the penis with blood to achieve and maintain an erection are blocked or hardened, or the lining of these arteries are damaged, blood flow is reduced. Vascular dysfunction not only affects the small arteries of the penis, but the larger coronary arteries of the heart too. Astute doctors now recognize that ED may actually be an early warning sign of impending cardiovascular disease, showing up several years before a cardiovascular event like a heart attack or stroke.2 To maintain healthy vascular function, and in turn, normal erectile function, consider these supplements:
Leafy green vegetables, like celery and spinach, may increase circulation because of their high concentration of nitrates. Beet juice has been found to be really high in nitrates. Nitrates are vasodilators, which means they open up blood vessels and increase blood flow. Many years before the U.S. Food and Drug Administration approved the first ED drug in 1998, several case reports on the beneficial effects of nitrates for erectile dysfunction had already been published. The ED drugs used today are based on the relaxing effects of nitrates on the blood vessels that supply the penis.
As men age, their estrogen levels gradually rise, while testosterone levels fall. Anti-cancer coupounds called indoles can help strike a balance. Cruciferous vegetables like broccoli are rich in indoles, which boost testosterone production by breaking down and flushing the system of excess estrogen, which inhibits the production of male sex hormones. In one study, supplementing with indole-3-carbinol from cruciferous vegetables for just 7 days cut the estrogen hormone estradiol in half for men. Another study found indole supplementation significantly increased urinary excretion of estrogens.
For many men, stopping smoking is an erectile dysfunction remedy, particularly when ED is the result of vascular disease, which occurs when blood supply to the penis becomes restricted because of blockage or narrowing of the arteries. Smoking and even smokeless tobacco can also cause the narrowing of important blood vessels and have the same negative impact.
