Prolactin levels in the premenstrual syndrome

Abstract
Serum prolactin was measured in 18 subjects complaining of premenstrual syndrome and results were compared with those in 10 control subjects. No consistent changes were seen during the course of the menstrual cycle in either group. There were no significant differences between the prolactin levels of the 2 groups. There was no correlation between mood change and levels of prolactin.
