Long-term effect of testosterone therapy on bone mineral density in hypogonadal men

Abstract

In both men and women, a decrease in bone mineral density (BMD) is a major symptom of hypogonadism. Although the effects of estrogens on osteoporosis in women are well documented, comparatively little is known about the effects of long term testosterone substitution on BMD in hypogonadal men. Therefore, we studied BMD in 72 hypogonadal patients (37 men with primary and 35 men with secondary hypogonadism) under testosterone substitution therapy that continued for up to 16 yr. Thirty-two of these men were also seen before initiation of therapy. At annual intervals, trabecular BMD of the lumbar spine was measured by quantitative computed tomography, a true volumetric and reproducible method for long term serial BMD measurements. Serum levels of testosterone increased to the normal range in all androgen-treated hypogonadal men. The most significant increase in BMD was seen during the first year of testosterone treatment in previously untreated patients, when BMD increased from 95.2 ± 5.9 to 120.0 ± 6.1 mg/cm3 hydroxyapatite (mean ± se). Long term testosterone treatment maintained BMD in the age-dependent reference range in all 72 hypogonadal men, independent of the type of hypogonadism. Transdermal testosterone patches applied to the scrotum were as effective in normalizing BMD as im testosterone enanthate injections. In summary, testosterone therapy increases BMD in hypogonadal men regardless of age. The greatest increase is seen during the first year of treatment in previously untreated patients with low initial BMD. In hypogonadal men, BMD can be normalized and maintained in the normal range by continuous, long term testosterone substitution.

  • Testosterone replacement increases bone mineral density and improves trabecular structure and bone mechanical properties.

    “Treatment increases BMD (132-135) and improves trabecular structure (136) and bone mechanical properties (137).”
  • Testosterone replacement increases libido, sexual motivation and sexual function, mood, sense of well-being, concentration, self-reported sense of energy, muscle mass and strength, and recovery of anemia related to testosterone deficiency.

    “T replacement increases libido, sexual motivation and sexual function (134,135,138-143), mood (144), sense of well being, concentration (135,139,143,145-147), self-reported sense of energy (134,135), muscle mass and strength (132,148,149), and the recovery of anemia related to T deficiency (134).”

    From Hormonal Replacement in Hypopituitarism in Adults: An Endocrine Society Clinical Practice Guideline (2016) · cites this paper as [135]

    The Abstract and Discussion report increased bone mineral density in hypogonadal men, not the sexual, psychological, muscular, or anemia-related outcomes in the claim. Searches for muscle strength and the other claimed outcomes found no passage reporting those effects; muscle mass and strength appear only in the title of another study in the References.

  • T therapy in males with central hypogonadism reduces fat mass and increases fat-free mass.

    “T therapy in males with central hypogonadism reduces fat mass and increases fat-free mass (132,135,140,148,149).”

    From Hormonal Replacement in Hypopituitarism in Adults: An Endocrine Society Clinical Practice Guideline (2016) · cites this paper as [135]

    The Patients section includes men with secondary hypogonadism, but the study measures bone mineral density, not changes in body composition. The Results and Discussion report increased bone mineral density with therapy; searches for fat mass, fat-free mass, and body composition found no passage supporting the claimed effects.

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.
