[Prolactin secretion during sleep at puberty. Preliminary results (author's transl)]

Abstract

Plasma prolactin was measured in six normal boys, during night sleep, with simultaneous recording of EEG for determination of the various stages of sleep. Peaks of prolactin appear clearly during cycles of rapid sleep: in prepuberty, the average of night peaks of prolactin is higher than that in post-puberty subjects. These results suggest indirectly, a participation of prolactin in prepuberty adrenal maturation.
