As we all know, the main physiological role of vitamin D is to regulate the body’s calcium and phosphorus metabolism as well as bone mineralization. Recent studies have showed that vitamin D receptors were expressed widely in the male reproductive system. Relative researches also found that the deficiency and insufficient of vitamin D was related to the declined male reproduction. The present study is to review both the biology and metabolism of vitamin D, and the effect of vitamin D on the male reproduction. The present review would be useful for further understanding the effect of vitamin D on the male reproduction, and would provide theoretical basis for the treatment of male infertility.
