Abstract

The intriguing notion of the menstrual cycle's having an acute impact on bone metabolism is examined as an expression of estrogen changes manifest as fluctuations in calcium-regulating hormones or biomarkers of bone formation/resorption. The effects of estrogen, progesterone, androgens, and follicle-stimulating hormones on bone health are also reviewed here. To date, the balance of evidence suggests that the menstrual cycle may exert a significant effect on bone metabolism. Further research needs to be conducted, however, to define these hormonal relationships.
