Abstract

Summary: Objective: To determine serum concentrations, intra‐individual variability and impact of age‐related co‐morbidities on serum testosterone (T), dihydrotestosterone (DHT), estradiol (E 2) and estrone (E 1) in older men. Design: Observational, repeated measures study. Participants: Men (n = 325) with 40 years and older self‐reporting very good or excellent health. Measurements: Standardized history, physical examination and collection of nine blood samples at fixed time intervals were measured over 3 months (three at 20 min intervals on days 1 (fasting) and 2 (non‐fasting), one at days 7, 30 and 90). Serum T, DHT, E 2 and E 1 (n = 2900, > 99% of scheduled samples) measured by liquid chromatography‐tandem mass spectrometry (LC‐MS) were analysed by linear mixed model analysis with fasting, age and obesity as covariables. Results: Mean serum T did not vary with age (P = 0·76) but obesity (−0·35 n m per body mass index (BMI) unit, P < 0·0001) and ex‐smoker status (−1·6 n m, P < 0·001) had significant effects. Serum DHT was increased with age (+0·011 n m per year, P = 0·001) but decreased with obesity (−0·05 n m per BMI unit, P < 0·0001). Serum E 2 did not vary with age (P = 0·31) or obesity (P = 0·12). Overnight fasting increased (by 9–16%, all P < 0·001) and reduced variability in morning serum T, DHT, E 2 and E 1. Non‐fasting serum T and DHT were stable over time (day, week, month or 3 months; P > 0·28). Conclusions: Serum T, DHT and E 2 displayed no decrease associated with age among men over 40 years of age who self‐report very good or excellent health although obesity and ex‐smoking status were associated with decreased serum androgens (T and DHT) but not E 2. These findings support the interpretation that the age‐related decline in blood T accompanying non‐specific symptoms in older men may be due to accumulating age‐related co‐morbidities rather than a symptomatic androgen deficiency state.

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.
