Is PCOS an inflammatory process?

PRO--PCOS is associated with low-grade systemic inflammation as evidenced by elevation of multiple markers of inflammation such as C-reactive protein, interleukin-18, monocyte chemoattractant protein-1 and white blood cell count as well as endothelial dysfunction and increased oxidative stress. CON--Current studies examining the evidence for low grade inflammation in PCOS are small, heterogeneous for the diagnosis, confounded by degree of adiposity and do not consistently demonstrate a clinically relevant increase in the above mentioned biomarkers.
