Hormones in Urine of a Normal Non-Pregnant Woman.∗

Summary This report concerns the daily excretion of estrogenic hormone in both free and combined chemical forms during one menstrual cycle of a normal muciparous woman. The possible excretion of gonadotropic hormone is reported merely that comparisons may be made with the reports of other workers. I feel that the excretion of this has not been demonstrated. Evidence of a significant association between the events of the menstrual cycle and changes in the amount and chemical form of estrin is discussed.
