Vitamin D is an emerging factor influencing fertility. The basis of this relationship lays on the presence of both vitamin D receptor and 1α-hydroxylase enzyme in reproductive organs. The widespread of vitamin D deficiency across all age groups and the published studies about the negative impact on overall health led to several investigations to assess the effect of vitamin D levels in human reproduction. Vitamin D status correlates to metabolic and hormonal dysfunctions in women with polycystic ovary syndrome and vitamin D deficiency is a negative predictor of ovulatory response in those women. Also, a positive correlation between vitamin D levels and anti-Müllerian hormone have been documented. Evidence suggests a link between lower vitamin D status, and endometriosis and vitamin supplementation has been associated with amelioration of dysmenorrhea. Studies in men revealed a positive correlation between circulating vitamin D levels and semen quality parameters. Vitamin D supplementation is being considered to improve semen quality in at least some of the idiopathic cases of male infertility. The relationship between vitamin D levels and assisted reproductive techniques outcomes have also been investigated, although the results are controversial. This paper intends to review the latest knowledge concerning the role of vitamin D in human reproduction.
