Hyperthyroidosis in pregnancy (16 cases) severely alters positive and negative correlations between maternal and neonatal thyroid hormones, as well as the morphofunctional state of the placenta. Chronic placenta failure (degrees I-II) and activation of the structures responsible for additional synthesis of placental lactogen results in transplacental passage of thyroxin to the fetus and newborn.
