Anterior pituitary function during early neonatal period

Anterior pituitary responsiveness to parturition was studied in 28 normal newborn infants. Cord blood sera samples were obtained for measurement of TSH, HGH, PRL, and FSH at birth and at intervals during four hours. The neonate infant's pituitary response to parturition consists of both PRL and TSH increments, which is probably mediated by an increase in TRH release.
