Summary The fine structure of the fetal rat thyroid and parathyroid glands was studied at term and during prolonged gestation, which was induced by subcutaneous injections of progesterone to the mothers from gestational days 20 through 24. At term, the follicular and parafollicular cells of the thyroid as well as cells of the parathyroid exhibited well developed cytoplasmic organelles. Morphological changes were not detected in either of the endocrine glands during prolonged gestation. The results are discussed in relationship to 1) thyroid follicular cell activity during stress and 2) the function of thyroid parafollicular and parathyroid cells in calcium homeostasis.
