Moving past the battle between good and evil hormones in a compelling new book about women’s health
Vancouver, Canada, June 10, 2009

The evidence is in. Estrogen does not halt aging or protect women from heart disease and dementia, nor is it the safest or best treatment for the hot flashes, night sweats and the insomnia that are associated with menopause and perimenopause. Quite simply—estrogen is not a good and magical hormone—as Susan Baxter, PhD., and Dr. Jerilynn C. Prior, painstakingly prove in their book, The Estrogen Errors; Why Progesterone is Better for Women’s Health.

“The Women’s Health Initiative, the largest (in history) clinical trial of women’s hormones conclusively showed that our infatuation with estrogen was just plain wrong.” Baxter adds, “They followed almost 28,000 women finding that menopausal women who took the placebo instead of estrogen or estrogen/progestin were healthier. Yet even now, women are being told it wasn’t the estrogen that was at fault but the dosage and timing.”

“For over 30 years,” Prior notes, “I have worked with my patients, designed studies to address women’s unanswered questions, and conducted randomized trials on the subject of hormones and health. Our book shows that contrary to the estrogen myth, it’s progesterone with estrogen that makes a girl, a woman. One researcher refusing to believe me asserted that progesterone is evil.”

In their lively, in-depth book, Baxter and Prior put to rest the debate about hormone replacement therapy and explain how too much estrogen can dangerously increase a woman’s risk of breast cancer, strokes, blood clots and more. Based on scientific evidence, personal experience, case studies, historical and sociological analyses, this readable book explains how progesterone, which balances out estrogen during each menstrual cycle, is essential for optimal health.

Baxter, an experienced medical journalist and social scientist, has extensively investigated the medical and popular literature about hormones and women’s health. With her almost encyclopedic knowledge about the literature, Baxter needed to buttress her theoretical understanding and analysis with specific medical information and clinical insights. So she turned to Dr. Jerilynn C. Prior, MD.

Prior, a pioneering endocrinologist; founder of the Centre for Menstrual Cycle and Ovulation Research (CEMCOR); and professor of Medicine at the University of British Columbia, has worked tirelessly and against considerable odds to educate medical practitioners and women everywhere about the importance of progesterone for women.

Estrogen Errors, a book written for lay people, doctors, and other interested professionals, moves us beyond the good and evil hormone discussion. It’s an examination of how we got here and how we can move forward to a more balanced view of the reproductive hormones necessary for a woman’s health throughout her life cycle.
