Erectile Dysfunction Defined:
The inability of a male to maintain an erection sufficient for satisfying sexual activity.
Endothelial Dysfunction and ED:
Endothelial dysfunction is the cause of both vascular disease and erectile dysfunction.
The inner lining of every artery, including the penile arteries, is a single layer of cells called the endothelium. When this wallpaper-like lining was healthy, it produced the gas nitric oxide (NO), which resists plaque, clotting, or constriction of arteries. A good endothelium leads to good sustained erections, just as it leads to good heart artery flow. Endothelial dysfunction (ED) leads to a poor blood flow response throughout the body.

L-arginine is an amino acid that helps make proteins. It also becomes the gas nitric oxide (NO) in the body. NO is important for erectile function because it helps blood vessels relax, so more oxygen-rich blood can circulate through your arteries. Healthy blood flow to the arteries of the penis is essential for normal erectile function.
