Male sexual health may be improved with vitamin D and sun exposure, University of Copenhagen researchers reported this week — another reason researchers are saying that overzealous sun avoidance is unnatural and has potential negative side effects.
“Would-be fathers should make the most of the next sunny day by taking off their shirt and topping off their tan,” London’s Daily Mail reported in a story Saturday. “A study of 340 men found that vitamin D, produced by the body when exposed to the sun, boosts the quality of sperm.”
According to the research team, sperm in vitamin D sufficient men were better at swimming toward an egg, had more speed and were better able to penetrate the egg. Their findings were published this month in the journal Human Reproduction and correspond to previous research linking low vitamin D levels to decreased sperm production.
