Values are means±standard deviation of n=8–9/group. Letters a–d indicate differences from respectively labeled groups at p<0.05 or * p<0.01 (a=vs. SHAM, b=vs. SCI, c=vs. SCI+LowTE, d=vs. SCI+HighTE). SCI, spinal cord injury; SCI+LowTE, spinal cord injury plus low-dose testosterone-enanthate; SCI+HighTE, spinal cord injury plus high-dose testosterone-enanthate. Cn.BV/TV, cancellous bone volume; Tb.N, trabecular number, Tb.Wi, trabecular width; Tb.Sp, trabecular separation; Oc.S/BS, osteoclast surface; Ob.S/BS, osteoblast surface; OS/BS, osteoid surface; MS/BS, mineralizing surface; MAR, mineral apposition rate, BFR/BS, bone formation rate/bone surface.
