What is a primary effect of Selective Estrogen Receptor Modulators (SERMs) in osteoporosis management?

• A. They cure osteoporosis completely.
• B. They permanently suppress bone turnover.
• C. They act like estrogen and reduce osteoporosis risk.
• D. They increase estrogen production in the body.

Answer: (C)

SERMs selectively mimic estrogen in bone, which helps limit bone resorption and preserve or improve bone density, thereby lowering fracture risk. In osteoporosis management, this estrogen-like effect at bone is the main benefit, since it helps prevent vertebral and other fractures without raising circulating estrogen levels. They don’t cure osteoporosis, they don’t permanently shut down bone turnover, and they don’t increase estrogen production. Their tissue-selective action means they act like estrogen in bone while blocking estrogen effects in other tissues.
