Follistatin can act as an important regulator of folliculardevelopment and cellular function due to its ability to bind and neutralize activins and bonemorphogenetic proteins (BMPs). Overexpression of follistatin gene in transgenic miceresulted in infertility and arrest of ovarian folliculogenesis at early stage as seen in womenwith polycystic ovary syndrome (PCOS). Follistatin has been published to be a candidategene for women with PCOS by linkage analysis. Serum circulating follistatin levels wasreported to be higher in women with PCOS than those without PCOS. However, the roles ofhigh extragonadol origin follistatin secretion play in women with PCOS remain unknown. Ithas been reported that the serum follistatin levels may increase following bacterial compoundinduced inflammatory reactions. Women with PCOS were reported to have high prevalence oflow-grade inflammation comparing with those women without PCOS. But most of the studiesattribute this phenomenon to the high prevalence of obesity in women with PCOS. Studiesregarding to follistatin, hsCRP and obesity in women with PCOS are not yet available.Besides, how the low-grade inflammatory status of women with PCOS affects the ovulatoryfunction is also unknown. Therefore, we design this 3-year study including prospectivestudies with intervention and in-vitro studies to investigate the possible role of follistatin andlow-grade inflammatory cytokines plays in the pathogenesis of polycystic ovary syndrome.多囊性卵巢症候群卵泡抑制素肥胖胰島素抗性高雄性素血症慢性低 度發炎反應Polycystic ovary syndromefollistatinobesityinsulin resistanceinflammationtestosterone
