Figure 10. The effects of testosterone therapy on bone health in intervention trials. Panel A shows the effects of testosterone therapy on lumbar and femoral bone mineral density in a meta-analysis of randomized trials (data derived from a meta-analysis by Tracz et al, J Clin Endocrinol Metab. 2006;91(6):2011-6.; figure adapted with Spitzer et al. Nat Rev Endocrinol. 2013;9(7):414-24). Panels B and C show the effects of testosterone replacement for 12 Months on volumetric bone mineral density and estimated bone strength of trabecular, peripheral, and whole bone of the spine and hip, as assessed by quantitative computed tomography (figure reproduced with permission from Snyder et al. JAMA Intern Med. 2017;177(4):471-479).
