Menstrual Cycle and Ovulation (CeMCOR)

Researchers at the Centre for Menstrual Cycle and Ovulation Research (CeMCOR) focus on reframing, in a modern, scientific context, fundamental understandings of the menstrual cycle and the life cycle of women’s reproductive hormones.

A major focus of the Centre is the study of the effects of progesterone therapy on metabolism, endothelial function, and bone changes, as well as affects of menstrual cycle disturbances on women’s overall health from adolescence to menopause. A significant component of activities also involves public education and the translation of research findings into changes in clinical practice.

Guided by women’s perspectives, CeMCOR translates new knowledge into practical, plain language for women world-wide.
