Research has shown an association between PCOS and chronic inflammatory factors, proinflammatory cytokines such as interleukin-1, interleukin-6, interleukin-17 [41–43], and tumour necrosis-α, and a variety of inflammation-related genes, including VEGF, tissue factor, and RAGE [44, 45]. Here, IL17A is linked to polycystic ovary syndrome.
