Abstract
The functional state of the pituitary-thyroid system was studied in pregnant rabbits and in their fetuses during the last third of pregnancy. Between the 23rd and 27th day of pregnancy the uptake of131I and the intensity of hormone synthesis in the thyroid glands of mother and fetus were increased; this, together with changes in the histological structure of the gland, was evidently connected with an increase in the thyroxine requirement at this period in the mother + fetus system. The above-mentioned changes in the mother were preceded by increased thyrotropic function of the pituitary, but no such correlation was found in the fetus. The results are evidence that the functional activity of the maternal pituitary-thyroid system changes rapidly in accordance with the body's requirements of thyroid hormone.
