Evening administration of melatonin enhances the pulsatile secretion of prolactin but not of LH and TSH in normally cycling women

Abstract

Exogenous melatonin has a stimulatory effect on PRL release without affecting the temporal pattern of its pulsatile secretion in normal women. Melatonin has minor, if any, effect on TSH secretion whereas the effect on LH may depend on individual sensitivity.
