The purpose of this study is to learn if obese pre- and early pubertal girls with
hyperandrogenemia (HA) are more insulin resistant (i.e., have lower insulin-stimulated
glucose disposal) compared to obese peripubertal girls without HA; and that overnight mean
luteinizing hormone (LH) concentration is also an independent predictor of free testosterone
concentrations, especially in mid- to late pubertal girls.
