Hormones in premenstrual syndrome

Twenty patients with Premenstrual Syndrome [PMS] and eighteen control subjects were studied to determine whether estrogen, progesterone, or prolactin hormone levels are associated with PMS. Blood samples were collected 7-10 days before the menstrual cycle. There was no significant differences between the two groups [P>0.1] indicating the endocrine effect during the luteal phase which do not directly generate the symptoms of PMS
