However, it is difficult to distinguish the direct effects of impaired insulin signaling from those of adiposity or hyperglycemia because these conditions often coexist in human syndromes and animal models of insulin resistance. In this study, we used lean, normoglycemic mouse lines with differing degrees of hyperinsulinemia and insulin receptor (Insr) expression to dissect the effects of altered insulin signaling on female reproduction. All three mouse lines [Ttr-Insr\u2212\/\u2212, Insr+\/\u2212, and Insr+\/+ (wild type)] are able to maintain fertility. However, the insulin-resistant and hyperinsulinemic mice demonstrate altered duration of estrous cycles as well as aberrant distribution and morphology of ovarian follicles. These effects appear to be independent of hyperandrogenism in the mice. Pregnancy studies indicate decreased success in early progression of gestation. In successful pregnancies, decreased embryo weights and increased placental calcification also implicate altered insulin signaling in later gestational effects. Thus, abnormal insulin signaling, independent of adipose tissue mass, adipokine expression levels, and hyperglycemia, can affect parameters of the female hypothalamic-pituitary-gonadal axis and pregnancy outcomes.<\/jats:p>","DOI":"10.1210\/en.2009-0788","type":"journal-article","created":{"date-parts":[[2010,2,23]],"date-time":"2010-02-23T02:10:08Z","timestamp":1266891008000},"page":"1863-1871","source":"Crossref","is-referenced-by-count":37,"title":["The Effect of Insulin Signaling on Female Reproductive Function Independent of Adiposity and Hyperglycemia"],"prefix":"10.1210","volume":"151","author":[{"given":"Anindita","family":"Nandi","sequence":"first","affiliation":[{"name":"Department of Medicine (A.N., D.A.)
