Hyperinsulinemia may contribute to hyperandrogenism because it reduces the levels of SHBG and IGFBP-1. In this study we determined serum levels of SHBG and IGFBP-1 and their association with androgen and insulin in 44 selected girls with premature pubarche (PP) and 18 pre-pubertal controls (C) (7.3±1.3 x 6.8±1.6years). The body mass index (BMI) and bone age (BA) were determined, as well as the serum levels of SHBG, IGFBP-1, insulin (I), glucose (G), testosterone (T), DHEAS, androstenedione (A), 17-hydroxyprogesterone (17OHP) and […]
