The aetiology of premenstrual syndrome is with the progesterone receptors.
Recent work by molecular biologists into the behaviour of progesterone receptors (PR) has suggested an aetiological hypothesis for premenstrual syndrome (PMS). The proposition is that PMS is related to the transport by PR of sufficient progesterone (P) molecules into the cell nuclei during menstruating years. PR are widely distributed in target cells throughout the body (1, 2, 3, 4, 5, 6, 7). It suggests also why measuring P blood levels is of no value in PMS (8, 9, 10, 11); why pharmacological doses of P are required (8); and explains the failure of current double blind trials using low dose P (12, 13, 14, 15, 16).
