To test the hypothesis that premature thelarche is associated with increased FSH\u2010driven follicular development, we measured inhibin\u00a0B and FSH in girls with premature thelarche, girls with central precocious puberty (CPP) and controls matched either for age or breast stage.<\/jats:p><jats:p><jats:bold>Patients\u2002<\/jats:bold> Blood samples were collected from 11 girls with premature thelarche (breast stage\u00a02, aged 0\u00b74\u20135\u00b76\u00a0years), 11 prepubertal controls age\u2010matched to the thelarche girls (0\u00b75\u20135\u00b74\u00a0years), 13 girls with CPP (breast stage\u00a02, 3\u00b79\u20138\u00b72\u00a0years) and nine normal pubertal controls (breast stage\u00a02, 9\u00b70\u201313\u00b72\u00a0years).<\/jats:p><jats:p><jats:bold>Measurements\u2002<\/jats:bold> Dimeric inhibin\u00a0B was measured in plasma by double\u2010antibody enzyme\u2010linked immunoassay and FSH by immunoradiometric assay.
