Abstract

Objective: Oxidative stress and inflammation play a vital function in the pathophysiology of polycystic ovary syndrome (PCOS) and infertility. The aim of this work was to control the impacts of vitamin D intake on metabolic profiles in infertile subjects with PCOS.

Trial Design And Methods: This randomized, double-blinded, placebo-controlled clinical trial was carried out among 40 infertile women with PCOS. Subjects were randomly divided into two intervention groups to take either 50 000 IU vitamin D (=20) or placebo (=20) weekly for 8 weeks. Metabolic profiles and few inflammatory cytokines expression evaluated on peripheral blood mononuclear cells (PBMCs) of participants, using real-time polymerase chain reaction (RT-PCR) method.

Results: Vitamin D intake decreased high-sensitivity C-reactive protein (hs-CRP) (-0.9±1.1 vs. 0.3±0.9 mg/l, =0.002) and elevated total antioxidant capacity (TAC) levels (49.2±60.2 vs. -50.6±161.8 mmol/l, =0.02) compared with placebo; but no significant effects on other metabolic parameters were observed. Moreover, a significant downregulation of tumor necrosis factor alpha (TNF-α) expression (=0.03) was observed after taking vitamin D compared with the placebo.

Conclusions: Overall, vitamin D intake for eight weeks had beneficial impacts on hs-CRP, TAC, and TNF-α among infertile women with PCOS.
