Figure 1
Response of WT and ER knockout mice to gonadectomy. Mice were sham-operated (black bars) or gonadectomized (white bars) at 12 weeks of age, and bones were collected after 8 weeks. (a) Tb.BMD and BV/TV were significantly reduced in male mice of all genotypes after orchidectomy. (b) Tb.BMD and BV/TV were significantly reduced after ovariectomy in female mice of all genotypes except ERαβ–/–. Values are mean ± SEM. *P < 0.05, **P < 0.01, ***P < 0.001 vs. sham-operated of the same genotype.
