Baseline UFC levels were not different between PCOS and HVs; on the day after the completion of high-dose dexamethasone administration (d 6), UFC was higher in the PCOS group (2.0 \u00b1 0.7 \u03bcg\/m2\u00b7d) than the HV group (1.5 \u00b1 0.5) (P = .038). On day 5, 17OHS and UFC were negatively correlated with adrenal volumes (left side, rp = \u22120.47, P = .009, and rp = \u22120.61, P &lt; .001, respectively). PCOS patients above the 75th percentile for UFC and\/or 17OHS after high-dose dexamethasone (n = 15) had a significantly smaller total adrenal volume (6.9 \u00b1 1.9 cm3 vs 9.2 \u00b1 1.8 cm3, P = .003) when compared with the remaining PCOS patients (n = 22), but they did not have worse insulin resistance or hyperandrogenism.<\/jats:p>\n <\/jats:sec>\n \n Conclusions:<\/jats:title>\n In a subset of young women with PCOS, we detected a pattern of glucocorticoid secretion that mimicked that of patients with micronodular adrenocortical hyperplasia: they had smaller adrenal volumes and higher steroid hormone secretion after dexamethasone compared with the group of PCOS with appropriate response to dexamethasone.<\/jats:p>\n
