Abstract
Polycystic Ovary Syndrome (PCOS) is one of the most frequent endocrinopathies, affecting 5–10% of women of reproductive age, and is characterized by the presence of ovarian cysts, oligo, or anovulation, and clinical or biochemical hyperandrogenism [1]. Metabolic abnormalities such as hyperinsulinemia, insulin resistance, cardiovascular complications, dyslipidemia, and obesity are frequently present in PCOS women [1]. Several key pathogenic pathways overlap between these metabolic abnormalities, notably chronic inflammation. The observation that this mechanism was shared led to the hypothesis that a chronic inflammatory state could contribute to the pathogenesis of PCOS [2]. Moreover, while physiological inflammation is an essential feature of reproductive events such as ovulation, menstruation, implantation, and labour at term [3], the establishment of chronic inflammation may be a pivotal feature of the observed reproductive dysfunctions in PCOS women [2]. Taken together, the present work aims to review the available evidence about inflammatory mediators and related mechanisms in women with PCOS, with an emphasis on reproductive function.
