Male Reproductive Health and Vitamin D

Vitamin D could play an important role in improving male reproductive health, according to a new study from researchers at the University of Copenhagen and Copenhagen University Hospital.

A study of 300 men, showed a positive correlation between the percentage of motile sperm and vitamin D levels.

Dr. Martin Blomberg Jensen, Department of Growth and Reproduction, Copenhagen University, said “In animals it is known that vitamin D deficiency results in low sperm count and low sperm motility and if you knock out the vitamin D receptor in mice it results in low sperm motility and low sperm number. We have recently shown that the vitamin D receptor and all metabolizing enzymes are express in human testis and spermatozoa. Now we show that vitamin D is important for human spermatozoa by showing that activated vitamin D induces sperm motility in the lab”.

Men with high vitamin D levels of up to 75 nmol/l had a significantly higher sperm motility compared with vitamin D deficient men with up to <25 nmol/l men. But the results are not sufficient to justify changing treatments, said Jensen. “This finding is not sufficient in determining whether vitamin D supplements may improve sperm quality in normal or infertile males. This study is one in a line of studies indicating that vitamin D is necessary for male reproduction.” More research is needed to identify relevant factors and conduct placebo-controlled trials to clarify whether vitamin D supplements are beneficial for infertile men, said the researchers. There is no known medical treatment proved to improve semen quality in well-designed randomised trials. Several papers have shown numerous positive associations between various treatments such as antioxidants, zinc, various vitamins and semen quality. Order Vitamin D today
