"Estrogen Errors is, quite simply, the truth! Dr. Jerilynn Prior has done women a huge service by uncovering the real truth about estrogen and the hidden secrets of progesterone! A must read for anyone concerned about women's health." -- Jerilynn C Prior MD FRCPC Professor of Endocrinology University of British Columbia " 'Estrogen Errors tells the story of efforts to set the record straight about how healthy ovulatory menstruation - with its ebb and flow of estrogen and progesterone - protects our hearts, breasts and bones, and details with sound scientific evidence the implications of this knowledge for women's health. It is also a call to action for women to become body literate. We owe it to ourselves and our daughters to understand and appreciate our bodies if we want to make conscious, informed decisions about our health throughout our reproductive lives - from menarche through to menopause and beyond." -- Laura Wershler Executive Director, Sexual Health Access Alberta "In this provocative book, Jerilynn Prior and Susan Baxter raise many key questions that women's health researchers and clinicians have failed to ask or investigate. They are especially effective in deconstructing prevailing myths about 'too little estrogen' during the peri-menopause." -- Judy Norsigian Executive Director, Our Bodies Ourselves "Jerilynn Prior can always be trusted to go beyond the surface to what is really happening in women's bodies. She is a true champion in women's health. This book will help you finally understand your body and hormones." -- Susan Love MD President of the Dr Susan Love Research Foundation and author of Dr Susan Love's Breast Book

In a book of importance to all women, expert authors provide an authoritative rebuttal to the widely held belief that estrogen therapy is the best treatment for perimenopausal women.

In this revealing work, a medical writer and an internationally known physician team up to explain the controversy over prescribing estrogen for perimenopausal women in the United States and to detail why progesterone is actually a far more effective, and far less risk-ridden, approach. Citing longstanding and emerging research, patient vignettes, and personal experience, endocrinologist Jerilynn Prior and writer Susan Baxter explain how false beliefs about estrogen became entrenched in U.S. medicine and culture—and how and why business and politics have played a role in this erroneous thinking.

Like most women in Europe now, Prior's patients find progesterone the key to dealing with a lifecycle transition that, contrary to Western medicine, these authors do not see as a disease. Challenging medical orthodoxy, The Estrogen Errors: Why Progesterone Is Better for Women's Health presents arguments and evidence that women and their doctors, male and female, will find compelling and useful.
