Vitamin D May Improve Abnormal Semen

Posted May 27 2011 12:00am
Taking vitamin D supplements may help improve signs of abnormal semen by increasing sperm movement, suggests a new study .

According to a study from the University of Copenhagen in Denmark, there is a significant relationship between blood vitamin D levels in men and the movement of sperm in a lab setting.

“This is an intriguing finding, because it suggest that vitamin D has an effect on sperm movement and function,” says Martin Blomberg Jensen of Copenhagen University Hospital.
Sperm movement, or sperm motility, is the the ability of a sperm to move in an efficient way toward the direction of an egg. Problems with sperm movement can be identified through an abnormal semen analysis which may also reveal any problems with sperm quantity, quality, or other factors contributing to male infertility .
The Danish study was conducted using semen samples from 300 healthy men and revealed that that those with the most motile sperm had the highest vitamin D levels in their blood.
Although this finding was significant, the researchers caution that there is not yet enough data to change current clinical practices. “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,” says Martin Blomberg Jensen.”
In addition to possibly improving abnormal semen by improving sperm movement, vitamin D has also been shown to protect against certain cancers, osteoporosis and several other diseases.
