Beata Banaszewska, Martyna Siakowska, Izabela Chudzicka-Strugala, et al. - Researchers here examined if and how polycystic ovary syndrome (PCOS) is associated with an elevation of markers of endotoxemia In this cross-sectional study, markers of endotoxemia were compared among women with PCOS (n = 62), healthy ovulatory women with polycystic ovary morphology (PCOM, n = 39) and a control group of healthy ovulatory women without PCOM [normal (NL), n = 43]. Findings revealed significantly greater serum levels of lipopolysaccharides (LPS), the LPS to HDL ratio and LPS-binding protein among women with PCOS vs normal control individuals.
