Vitamin D regulates calcium and phosphorus homeostasis in the body. In recent years, studies have been conducted examining the role vitamin D plays in reproduction. Vitamin D deficiency is associated with infertility, decreased pregnancy rates, and hormonal changes. Asians appear to have a reverse correlation with pregnancy rates and vitamin D levels.

This paper reviews the most recent literature focusing on the relationship between vitamin D status and infertility. This review evidences vitamin D levels >30 ng/mL result in improved fertility outcomes.
