Preventive Powers of Ovulation and Progesterone Ovulation and the Heart

We have been asking, through a series of newsletters, what we know about women’s health related to normal progesterone levels and ovulation. We have discussed the fact that ovulatory disturbances (meaning anovulation and short luteal phase cycles) are common and hidden within menstrual cycles that seem perfectly normal. I speculate that at least a third of all cycles in regularly menstruating, healthy women 10-30 years since menarche (their first period) produce too little progesterone. (We don’t really know the percentage of cycles with ovulatory disturbances in the general population because no one has studied it. CeMCOR in joint study with Norwegian scientists and funded by Canadian Institutes of Health Research is currently trying to learn what proportion of women’s cycles is anovulatory.)
