Table 1. Tomographic analyses of cortical bone.

	Sham	Orchiectomy
Cortical bone thickness (mm)	0.313 ± 0.014	0.326 ± 0.019
Cortical bone area (mm2)	7.022 ± 0.170	6.948 ± 0.214
Total bone section area (mm2)	8.200 ± 0.343	8.052 ± 0.265
Ratio of cortical area/total section area (%)	85.90 ± 0.02	86.40 ± 0.02

Male Wistar rats were subjected to sham operation or orchiectomy. Four weeks after surgery, animals were sacrificed, and their femurs were collected. These cortical bones were scanned using μCT. The cortical bone thickness, cortical bone area, and total bone section area were quantified. The ratio of cortical bone area over total bone section area were calculated. Each value represents the mean ± SD of three independent determinations.
