The pituitary of the human fetus in the second trimester of pregnancy contains a considerable amount of LH and HGH. The average LH and HGH contents of the pituitaries were found to be 3.4IU/gland and 2.3μg/gland, respectively. The pituitary content and concentration of HGH increased significantly as the fetal age advanced, although there were no remarkable changes in the pituitary content of LH. The pituitary incubated <I>in vitro</I> secreted LH, FSH and HGH into the medium. The addition of rat hypothalamic extract into the medium increased the release of LH and HGH by the pituitary. Synthetic LH-RH also enhanced the pituitary release of LH and FSH <I>in vitro</I>. However, in the pituitaries of the fetuses younger than the 16th weeks of gestation the secretion of LH and FSH <I>in vitro</I> was not stimulated by the addition of synthetic LH-RH. The results demonstrate that the anterior pituitary of the human fetus is responsive to hypothalamic releasing factors <I>in vitro</I> at least by the 19th weeks of fetal age.
