The development of a homologous radioimmunoassay (RIA) for the measurement of serum hamster prolactin (PRL) has facilitated our studies on monitoring the secretion patterns of this hormone during different states of reproduction. Four salient findings emerge from the present studies. First, rapid cardiac puncture without anesthesia does not affect serum PRL levels during selected times in the estrous cycle or during pregnancy. Second, serum PRL levels during the estrous cycle describe a daily rhythm of PRL release with maximum serum concentrations each day occurring in the afternoon and the highest of these occurring on proestrus (day 4 of cycle). Third, PRL release during pregnancy is characterized by a single surge each day; although the time of maximum PRL release varies, levels increase during the hours of darkness and decline to basal during the light. Fourth, the amount of PRL released during pregnancy diminishes with time; on day 15 the total amount of PRL in the serum is less than 10% of that measured on day 5.
