Abstract

Vitamin D is a steroid hormone with canonical roles in calcium metabolism and bone modeling. However, in recent years there has been a growing body of literature presenting associations between vitamin D levels and a variety of disease processes, including metabolic disorders such as diabetes and prediabetes and autoimmune conditions such as thyroid disease. This review focuses on the potential role of vitamin D in both male and female reproductive function. The vitamin D receptor (VDR) is expressed throughout central and peripheral organs of reproduction. VDR is often co-localized with its metabolizing enzymes, suggesting the importance of tissue specific modulation of active vitamin D levels. Both animal and human studies in males links vitamin D deficiency with hypogonadism and decreased fertility. In females, there is evidence for its role in polycystic ovary syndrome (PCOS), endometriosis, leiomyomas, in-vitro fertilization, and pregnancy outcomes. Studies evaluating the effects of replacing vitamin D have shown variable results. There remains some concern that the effects of vitamin D on reproduction are not direct, but rather secondary to the accompanying hypocalcemia or estrogen dysregulation.
