Abstract：Beginning with the uterus as one of the extraordinary organs，the authors discuss the relationship between storage and discharge function of the uterus and pathogenesis of emmeniopathy from various aspects，such as the dialectical unity relationship between storage and discharge， the uterus' governing menses via the control of storage and discharge function，as well as the uterus's losing control of storage and discharge. The authors think that for regulating menses，the priority should be given to the regulation of storage and discharge function of the uterus.
