Erectile dysfunction causes. Women repeatedly short-changed in case of premature ejaculation
Lacking enough of the sunshine vitamin might snuff out the lights on his bedroom game: New research from Italy suggests that low levels of vitamin D may increase a guy's risk of erectile dysfunction. When researchers tested men with varying degrees of erectile dysfunction, they found that nearly half of them were coming up deficient in D, and only one in five had optimal levels of the nutrient.
What's more, men with severe cases of ED had vitamin D levels that were about 24 percent lower than erectile dysfunction causes of men with mild forms of the condition. Insufficient levels of D may spur the production of free radicals called superoxide ions, says study author Alessandra Barassi, M.
These free radicals deplete your nitric oxide, a molecule that helps your blood vessels function properly.
The result: It makes it hard to, well, get hard. Without the necessary amounts of nitric acid, though, your blood vessels may not relax enough erectile dysfunction causes allow for an erection. As for men with normal erectile functioning, research is currently studying whether vitamin D supplementation may act as a preventive measure to delay ED. More from Men's Health:.
