News Roundup: Sunshine May Improve Male Fertility
Male fertility may get a boost from sunshine
A smidgen of sunshine could be beneficial for men’s sperm. Australian researchers found that one-third of 794 men visiting an infertility clinic had a vitamin D deficiency. Since getting only 10–15 minutes of sunshine a day can boost vitamin D levels, 123 men tried to do just that—along with taking vitamins and living a healthier lifestyle in general. The payoff? A 75% drop in sperm fragmentation, a measure of damage. Overall, 31 men had partners who conceived after making the changes.
