Abstract
Increasing levels of E2 in gonadotropin-treated women stimulated hepatic synthesis of SHBG and TBG, and consequently increases in T4 concentration. Nevertheless, unchanged FTI and TSH suggested that a euthyroid state was maintained. The temporal patterns for the rise in serum concentrations of TBG and SHBG during gonadotropin therapy suggest that the synthesis of these proteins by the liver has different sensitivities to E2.
