Abstract

In men, hypoandrogenism is associated with features of the metabolic syndrome. It is not known whether men with the metabolic syndrome are at a higher risk of developing hypogonadism. We therefore assessed whether the metabolic syndrome predicts development of hypogonadism 11 yr later in 651 middle-aged Finnish men participating in a population-based cohort study. Men with the metabolic syndrome at baseline as defined by the World Health Organization (n = 114, 20%) had a 2.6-fold increased risk of developing hypogonadism as defined by total testosterone levels less than 11 nmol/liter at the 11-yr follow-up independent of age, smoking, and other potential confounders. Further adjustment for body mass index (OR, 2.0; 95% CI, 1.1-3.8) or baseline total testosterone levels (OR, 1.9; 95% CI, 1.0-3.4) attenuated the association. The association of the metabolic syndrome with hypogonadism as defined by calculated free testosterone levels less than 225 pmol/liter was similar, but weaker. The adjusted decrease in testosterone concentrations during the 11-yr follow-up was also greater in men with than without the metabolic syndrome. Smokers had a nonsignificantly lower risk of developing hypogonadism during follow-up, whereas a decrease in smoking increased the risk of hypogonadism. The metabolic syndrome predisposes to development of hypogonadism in middle-aged men. Prevention of abdominal obesity and the accompanying metabolic syndrome in middle age may decrease the risk of hypogonad…

  • During a 13-year observation, a reduced number of cigarettes was associated with a greater decrease in testosterone, a higher risk of hypogonadism, and a greater increase in waistline compared to men who continued smoking without restrictions.

    “During the subsequent 13-year observation, a reduced number of cigarettes was, however, associated with a greater decrease in testosterone, a higher risk of hypogonadism defined by levels of total and free testosterone and a greater increase in waistline compared to men who continued smoking without restrictions.”

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.
