Conclusion: Overall, our findings demonstrated that infertile women with PCOS, who were candidate for IVF benefited from chromium supplementation for 8 weeks in terms of lowering hs-CRP and improving gene expression of PPAR-γ, GLUT-1, LDLR, and IL-1, though chromium had no effect on the gene expression of IL-8, TNF-α, TGF-β, and VEGF. Here, VEGFA is linked to polycystic ovary syndrome.
