Study shows positive link between percentage of motile sperm and serum vitamin D levels

March 27, 2017

"Low semen quality may have numerous causes, but it often has a fetal origin similar to some male genital malformations and testicular cancer. However, this study indicates that factors in adult life may also play a role for semen quality," says Professor Anders Juul from the University of Copenhagen and Copenhagen University Hospital's Department of Growth and Reproduction.

"It is important to find all factors of importance, because semen qaulity in Danish men is at a low level and contributing to a very high incidence of fertility problems among Danish couples," says Anders Juul.

The authors conclude that there is a need to intensify reproductive research to identify relevant factors and conduct placebo-controlled trials to clarify whether vitamin D supplements are beneficial for infertile men.
