Testosterone for the aging male; current evidence and recommended practice
Open accessAbstract
An international consensus document was recently published and provides guidance on the diagnosis, treatment and monitoring of late-onset hypogonadism (LOH) in men. The diagnosis of LOH requires biochemical and clinical components. Controversy in defining the clinical syndrome continues due to the high prevalence of hypogonadal symptoms in the aging male population and the non-specific nature of these symptoms. Further controversy surrounds setting a lower limit of normal testosterone, the limitations of the commonly available total testosterone result in assessing some patients and the unavailability of reliable measures of bioavailable or free testosterone for general clinical use. As with any clinical intervention testosterone treatment should be judged on a balance of risk versus benefit. The traditional benefits of testosterone on sexual function, mood, strength and quality of life remain the primary goals of treatment but possible beneficial effects on other parameters such as bone density, obesity, insulin resistance and angina are emerging and will be reviewed. Potential concerns regarding the effects of testosterone on prostate disease, aggression and polycythaemia will also be addressed. The options available for treatment have increased in recent years with the availability of a number of testosterone preparations which can reliably produce physiological serum concentrations.

Serum testosterone levels decline with age, commencing in men in their mid-30s and decreasing at an average annual rate of 1.6%.
“We speculate that this phenomenon may be attributed to the gradual decline in serum testosterone levels with age, commencing in men in their mid-30s and decreasing at an average annual rate of 1.6%38–43.”
From Association between serum cotinine and total testosterone in adult males based on NHANES 2011–2016 (2024) · cites this paper as [42]
The “Changes in testosterone levels with aging” section reports that total testosterone declines by an average of 1.6% per year. It does not say that the decline begins in men in their mid-30s; that onset age is unsupported by this source. The citing authors’ proposed explanation of their phenomenon is their own speculation, not a finding attributed to this paper. (LLM, conf=0.88)

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.
