In a new vitamin D study, researchers at the University of Copenhagen and its teaching hospital suggest the superstar vitamin could play a key role in improving male reproductive health.
There can be numerous causes for low quality semen, but it can often have fetal origins -- similar to some male genital malformations and testicular cancer. However, this study indicates that nutritional and environmental factors in adult life may also play a role in semen quality, which shouldn't really surprise anyone.
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 less than 25 nmol/L.
For Danish men, it's reported that the semen quality is quite low, and this contributes to the high incidence of fertility problems among Danish couples.
Denmark and Norway have the highest incidence of testicular cancer and impaired semen quality in the world. In Denmark, 10% of all children are born after assisted reproduction.
So men, take care of yourselves. We're fortunate that in today's society, being healthy is actually trendy.
