She also runs CEMCOR, the Center For Menstrual Cycle and Ovulation Research. Dr Prior has been prescribing progesterone for postmenopausal women and perimenopausal women to treat hot flashes, night sweats, heavy flow, and sore breasts for over 25 years. She has conducted and published research showing that progesterone is an effective treatment for menopausal hot flashes and night sweats. She also wrote a novel to help illuminate some of her findings called Estrogen’s Storm Season. You are going to hear a completely different set of views in this interview, so buckle up. Everything she says is deeply rooted in research, clinical practice and personal experience.
