Abstract

The purpose of this study was to determine whether bone density in older men was associated with serum sex steroids or sex hormone binding globulin (SHBG). Bone density and sex steroids were measured in men over age 65 at 6-mo intervals for an average of 2.1 yr. Bone density was significantly positively associated with greater serum E2 concentrations (+0.21 < r < +0.35; 0.01 < P < 0.05) at all skeletal sites. There were weak negative correlations between serum testosterone and bone density (-0.20 < r < -0.28; 0.03 < P < 0.10) at the spine and hip. SHBG was negatively associated only with bone density in the greater trochanter (r = -0.26, P < 0.05). Greater body weight was associated with lower serum testosterone and SHBG, and greater E2. Because of these associations, regression models which adjusted for age, body weight, and serum sex steroids were constructed; these accounted for 10-30% of the variability in bone density, and showed consistent, significant positive associations between bone density and serum E2 concentrations in men, even after adjustments for weight and SHBG. These data suggest that estrogens may play an important role in the development or maintenance of the male skeleton, much as is the case for the female skeleton. These data also indicate that, within the normal range, lower serum testosterone concentrations are not associated with low bone density in men.

  • In men, bone mineral density at the greater trochanter, femoral neck and the lumbar spine is negatively correlated with concentrations of SHBG.

    “Moreover, in men, bone mineral density (BMD) at the greater trochanter, femoral neck and the lumbar spine is negatively correlated with concentrations of SHBG [146, 150–152].”

    From Role of sex hormone-binding globulin in the free hormone hypothesis and the relevance of free testosterone in androgen physiology (2022) · cites this paper as [151]

    Table III (Results) reports negative SHBG–BMD correlation coefficients at the greater trochanter, femoral neck, and lumbar spine in men over 65. However, only the greater-trochanter association was statistically significant, as the Abstract explicitly notes; the claim omits that distinction. (LLM, conf=0.82)

    Experimental — accuracy not yet measured
  • The relationship between testosterone levels in aging and bone health is uncertain because studies have produced conflicting results.

    “These confounding results leave uncertainty in the relationship between T levels in aging and bone health.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
