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.
