Remaining 247 women underwent clinical assessments, excluding another 49 due to other endocrine diseases. The diagnosis of PCOS and prediabetes were based on Rotterdam and American Diabetes Association criteria, respectively.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      100 women had prediabetes and 98 women had normoglycemia. The frequency of PCOS were 17% and 19.4% in prediabetes and control groups, respectively (p=0.715). The frequency of PCOS was 24% (6\/25) in women with impaired glucose tolerance (IGT) only, 22.2% (2\/9) in women with impaired fasting glucose only, and 15.5% (9\/58) in women who met the HbA1\n                      <jats:sub>C<\/jats:sub>\n                      criterion only. Prediabetes group had higher insulin-like growth factor-1 (IGF\u20131) levels and lower anti-M\u00fcllerian hormone (AMH) levels (p&amp;lt;0.05). Insulin was correlated with testosterone, antral follicle count, and ovarian volume only in prediabetes group (p&amp;lt;0.05). Mediation models showed that insulin increased testosterone both directly and indirectly through increasing IGF-1 (b=0.4, p=0.0006).\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>While the rate of PCOS was not increased in overall prediabetes group, a trend for an increased risk in IGT subgroup only was noteworthy. Positive correlation of insulin with testosterone, antral follicle count, and ovarian volume being only found in prediabetes group suggested that prediabetes might render ovaries susceptible to the PCOS-like changes. The lower AMH in prediabetes implied the toxic effects of even mild hyperglycemia on ovaries.<\/jats:p>\n
