Testosterone and estradiol were assessed by liquid chromatography\/mass spectrometry; serum C-terminal telopeptide of type I collagen (CTX), osteocalcin and sclerostin by enzyme-linked immunosorbent assay; glycated hemoglobin (HbA1c) by high-performance liquid chromatography, areal BMD (aBMD) and body composition by dual-energy x-ray absorptiometry; tibial volumetric BMD (vBMD) and bone geometry by peripheral quantitative computed tomography.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Results<\/jats:title>\n                  <jats:p>Among our population of hypogonadal men, 49 had T2D and 56 were non-T2D.

Hypogonadal men with T2D had increased osteocalcin, reflecting increased osteoblast activity, compared with non-T2D men (P\u2005&amp;lt;\u2005.01). T2D men increased lumbar spine aBMD (P\u2005&amp;lt;\u2005.05), total area at 38% tibia (P\u2005&amp;lt;\u2005.01) and periosteal and endosteal circumferences at the same site (P\u2005&amp;lt;\u2005.01 for both). T2D men had reduced tibial vBMD (P\u2005&amp;lt;\u2005.01), but preserved bone mineral content (P\u2005=\u2005.01).
