WHAT'S SO SCARY ABOUT NANOPARTICLES? These wee critters can diffuse and penetrate easily, almost like the chemical equivalent of gamma rays, and it looks like where they do their most damage is in your arteries.
Nanoparticles lead to calcification, or hardening, of the arteries. Anything that hardens your arteries is, of course, bad for your health, but it's also bad for your sex life. You need nice, flexible penile arteries to allow blood into those critical erectile chambers.
Nanoparticles probably do their damage through a variety of routes, but one of the most likely paths is inflammation.
One study showed that alumina nanoparticles increased arterial inflammation and macrophage stickiness, which are leading culprits in the buildup of arterial plaque. et another pathway may be that these particles actually change cell permeability.
Subsequent research has been no more comforting. One 2009 animal study of titanium dioxide nanoparticles confirmed the ability of these compounds to wreak havoc with your sex life by showing that they actually decrease the all-important endothelial levels of nitric oxide, thus making arteries appear more stiff in the short term as well.
