Hypothalamic Control of the Development of Endocrine Functions in the Human Fetus
Human fetal endocrine development has been examined during the past 15 years, but data related to neuroendocrine regulation in fetal life are sparse in literature. To investigate the problem, we have compared the radioimmunologically determined concentrations of TSH, FSH, LH, and GH in the plasma with those in the cerebral liquor in 54 fetuses 15–35 weeks old, which had been dead for 2–10 h. Cerebral liquor was obtained by syringe from the undissected cerebral ventricles without any admixture of blood.
