Abstract

CONTEXT: The gonads are the major source of sex steroids during reproductive ages. The gonadal function declines abruptly in women and gradually in men. The adrenals produce 11-oxygenated androgens (11-oxyandrogens), which start rising during adrenarche. Following menopause, 11-oxyandrogens levels remain similar to reproductive ages. OBJECTIVE: To compare the circulating 11-oxyandrogen concentrations in men and women across adult ages. METHODS: We used mass spectrometry to measure testosterone (T), androstenedione (A4), 11β-hydroxytestosterone (11OHT), 11-ketotestosterone (11KT), 11β-hydroxyandrostenedione (11OHA4), 11-ketoandrostenedione (11KA4), cortisol, and cortisone in morning sera obtained from adults in outpatient setting. We performed double immunofluorescence of 3β-hydroxysteroid dehydrogenase type 2 and cytochrome b5 in adrenal tissue from 19 men, age 23-78 years. RESULTS: We included 590 patients (319 men), aged 18 to 97 years, and 84% white. 11KT and 11KA4 were stable across ages in women, but they declined in men (0.21 and 0.06 ng/dL/year, respectively; P < 0.05). 11OHA4 and 11OHT increased modestly with age in women (0.6 and 0.09 ng/dL/year, respectively; P < 0.01), and both remained stable across ages in men. As body mass index (BMI) increased, 11KA4 decreased in women, and 11KT increased in men, both suggesting higher 17β-hydroxysteroid dehydrogenase activity in obese individuals. A4 and T declined with age and A4 with BMI in both sexes; T declined with BMI in men. Adrenal androgenic enzyme expressions in aging men were similar to those observed in women. CONCLUSIONS: In contrast with traditional androgens, the production of 11OHA4 and 11OHT is sustained with aging in both sexes. The bioactive androgen 11KT declines in aging men but not in women.

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.
