Lack of sunlight linked to male infertility
AN Australian infertility study has revealed disturbing levels of vitamin D deficiency among men who are unable to impregnate their partners.
The discovery surprised Sydney researchers investigating the incidence of DNA fragmentation of sperm, a significant factor in male infertility.
Sunlight is the major source of vitamin D, which helps regulate levels of calcium and phosphorous to generate healthy bones.
Fertility specialist Dr Anne Clark screened the blood of almost 800 men with fertility problems, finding almost a third had lower than normal levels of vitamin D.
"In a significant number of these men, there were also elevated levels of homocysteine, an amino acid in the blood associated with cell toxicity, and deficiency in folate, which is essential for healthy new cells," said Dr Clark, medical director of the treatment centre Fertility First.
