Relationship between serum vitamin D and ovarian reserve function in patients with Polycystic Ovary syndrome

Background and objective: Polycystic ovary syndrome (PCOS) is one of the most common endocrine diseases in women of reproductive age. Studies have shown that vitamin D is associated with reproductive ability, metabolic alterations, and mental health of PCOS patients. The aim of this study is to investigate the difference of serum vitamin D levels between PCOS women and healthy control women, and the relationship of vitamin D with the concentration of the marker of ovarian reserve function, the anti-müllerian hormone (AMH).
