More Testosterone Foods
A different way that pro testosterone foods work involves improving your blood flow. Specifically, we are talking about improving blood flow to the penis and the testes. By stimulating circulation in these areas, you not only are able to improve the quality of your erections, you also allow for improved hormone stimulation and secretion.
The medical symptom most tightly associated with erectile dysfunction is coronary heart disease. By eating minimally processed grains like non-instant oatmeal, you are increasing your intake of soluble fiber and other nutrients that substantially decrease your risks of heart disease and clogged arteries (1).
For the same reason I describe above, increasing your consumption of beans of all kinds will improve your blood circulation, reduce your risk for clogged arteries, and generally maintain the healthy blood flow to the penis and testes. A few kinds of beans have another property to them as well. Fava beans in particular contain high levels of tyrosine and L-DOPA, both of which are compounds that get converted into the "pleasure messenger" dopamine.
Ginger and Garlic
Both ginger and garlic are frequently recommended for improving blood circulation and stimulating erections. The active compounds in garlic are known to be vasodilators. Ginger has been used for centuries as a sexual tonic. Ginger is best consumer raw or only slightly cooked. Garlic offers benefits when raw or cooked.
