N2 - Rapid increases in the number of elderly people have dramatically increased the number of female and male osteoporosis patients. Osteoporosis often causes bone fragility fractures, and males exhibit particularly poor prognosis after these fractures, indicating that control of osteoporosis is crucial to maintain quality of men's lives. However, osteoporosis therapies available for men have lagged behind advances available for women. Here, we show that three selective estrogen receptor modulators (SERMs), namely, raloxifene, bazedoxifene, and tamoxifen, plus the vitamin D analogue ED71, also called eldecalcitol, completely block orchiectomy-induced, testosterone-depleted bone loss in male mice in vivo. Patients treated with hormone deprivation therapy for prostate cancer also exhibit male osteoporosis, and bone management is critical for these patients. Given that androgen replacement therapy is not an option for these patients, our results represent a novel approach potentially useful to control male osteoporosis.
