Video: Older Women’s Fracture Prevention-The Importance of Bone Formation

Women’s bone health is closely related to the ovarian hormones, estrogen and progesterone. We have known for decades that estrogen prevents bone loss (called resorption). Our current osteoporosis medicines primarily work like estrogen and prevent bone loss—that includes all the bisphosphonates and the antibody drug called Denosumab. But bone remodeling (or renovation) involves both removing…
Does Taking Progesterone (alone or with estrogen) Increase Women’s Risk for Breast Cancer?

QUESTION “I am using Prometrium® (oral micronized progesterone) 300 mg before bed, as it is the only intervention I have tried (pharmaceutical and naturopathic) that has worked.

Use of “the Pill” and Bone Changes in Adolescent Women

Frequently Asked Questions about Anovulatory Androgen (AAE, or PCOS)

Frequently Asked Questions about Anovulatory Androgen (AAE, or PCOS) Are women with AAE estrogen deficient since they often have skipped periods or amenorrhea?

The ABCs of Osteoporosis Prevention for Men with Prostate Cancer on Testosterone-Lowering Treatment

The development of prostate cancer is sufficiently frightening without also worrying about a broken bone. Those men whose prostate tumours grow in response to male hormones (like testosterone [T]) are usually treated with “androgen depletion/ablation” meaning a medicine that lowers testosterone and/or decrease its actions. Why is this an osteoporosis risk? Because testosterone both normally…
