Vitamin D Has Positive Effect On Sperm Movement – Study

March 22, 2011: 09:58 AM EST
Danish researchers report that they have established a relationship between serum vitamin D and the movement of human sperm. The study conducted among 300 men found a positive association between the percentage of sperm capable of movement and the levels of serum vitamin D in the body. And when they stimulated the sperm in the lab with vitamin D, the forward movement of the sperm increased significantly. The researchers warned, however, that though their findings showed vitamin D was necessary for male reproduction, the findings were “not sufficient in determining whether vitamin D supplements may improve sperm quality in normal or infertile males.”
