Prior – Progesterone as Women’s Bone-Anabolic Hormone – New Approaches to Osteoporosis Management

Dr. Prior has conducted research that seriously challenges estrogen’s key role in preventing bone loss. Her research confirms that estrogen’s role in combating osteoporosis is only a minor one. In her study of female athletes, she found that osteoporosis occurred to the degree that the athletes became progesterone-deficient, even though their estrogen levels remained normal. She will review her research with non-athletic women, and showing the same results. While both of these groups of women were menstruating they had anovulatory (non-ovulating), cycles, and were thus deficient in progesterone. As a result of her extensive research, she confirmed that it is not only estrogen…but progesterone which is the key bone-building hormone. Such studies seriously challenge the estrogen deficiency-osteoporosis link.
