Low levels of vitamin D are associated with erectile dysfunction, according to a new study.
The researchers analyzed data from more than 3,400 American men aged 20 and older, disease-free cardiovasculaire.30% were deficient in vitamin D, which means that their plasma levels of 25 (OH) D3, vitamin D reserve, were less than 20 nanograms per milliliter of blood. 16% percent had erectile dysfunction.
The study found that vitamin D deficiency is found in 35 percent of men with erectile dysfunction, compared to 29 percent of people without erectile dysfunction. Vitamin D is a hormone equivalents, whose effects are manifold. The main source of vitamin D is exposure of the skin to ultraviolet B in fine weather. In the cold season, the vitamin D supplements are needed to maintain plasma levels.
“Vitamin D deficiency is easy to detect and easy to fix with lifestyle changes that include exercise, dietary changes, supplementation with vitamin D and sun exposure,” says lead author the study, Dr. Erin Michos, associate professor of medicine at the medical faculty of the Johns Hopkins University .
The researchers concluded that men with vitamin deficiency had a higher risk of 30% to be powerless, those whose vitamin levels are sufficient.
The researchers point out that this is an observational study does not prove cause and effect. More research is needed to determine if there is a direct link between vitamin levels and erectile dysfunction. If this is the case, this work could lead to new therapeutic approaches.
“Check vitamin levels may be a useful tool for assessing the risk of erectile dysfunction,” said Dr. Michos. Correcting the deficit could then reduce risks and help restore erectile function.
About 40% of Americans aged 40 years and 70% of those aged over 70 years are unable to achieve or sustain an erection for satisfactory sexual intercourse, the researchers said.
In France, 30% is estimated the proportion of men with ED between 30 and 69 years. Mineral D deficiency affects up to 40% of American adults, according to the Centers for Disease Control and Prevention. In France and more generally in Europe, it is also extremely common.
The study was presented Tuesday, November 10 at the annual meeting of the American Heart Association in Orlando, Florida.
