Vitamin D boosts sperm quality

Positive association between blood vitamin D levels and sperm motility

This study was carried out by researchers from The University of Copenhagen, Denmark and was funded by various research organisations, including the Danish Agency for Science, Technology and Innovation, and the Novo-Nordisk Foundation of the Novo-Nordisk pharmaceutical company. It was published in the peer-reviewed medical journal Human Reproduction.

The research 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 sperm would typically be exposed to in the human body.

The men in this study were recruited from the general population and although those with deficient vitamin D levels had less motile sperm, it is unclear whether this would be a sufficient impairment to cause problems for them to conceive with their partner.

Further research is needed to see whether vitamin D levels are associated with clinical fertility problems.
