Effect of prolactin on the secretion of dehydroepiandrosterone (DHEA), its sulfate (DHEA-S), and cortisol by the human fetal adrenal in vitro.

Abstract
The effects of prolactin on the secretion of dehydroepiandrosterone (DHEA) and its sulfate (DHEA-S) and that of cortisol were studied in vitro to investigate the possible regulatory role of prolactin on steroidogenesis of the human fetal adrenal at mid-gestational age. The addition of 0.5 .mu.g/ml of human prolactin to the incubation medium produced a significant (P < 0.05) increase in DHEA, DHEA-S and cortisol secretion. Prolactin apparently has a regulatory role in steroidogenesis in the human fetal adrenal at mid-gestation.
