Sperm motility - Wikipedia

Back to Pregnancy and child. The research behind this news was a two-part study that first tested the blood vitamin D levels and sperm motility of Danish men taken from the general population. The second part then looked at what happened when vitamin D was added to sperm samples from an additional 40 men. The researchers found vitamin D raised calcium levels in the sperm and that, in turn, increased their motility and the proportion of the sperm undergoing the changes needed to fuse with a female egg. This study shows that vitamin D can have an effect on sperm, but further work is needed to see whether the amount of vitamin D used in the experimental phase of this study reflects the range of vitamin D that sperm would typically be exposed to in the human body.
