Variability in total testosterone levels in ageing men with symptoms of androgen deficiency (original) (raw)

This study investigates the variability of total testosterone (TT) levels in healthy, non-obese ageing men exhibiting symptoms of androgen deficiency. A cohort of 96 men aged 55 years and older underwent TT measurements at four intervals within a year. Findings indicate that while intra-individual differences in TT levels were noted, a single measurement could generally predict repeat TT levels over the period; however, clinicians should consider repeat sampling due to the observed variability. The results suggest potential implications for diagnostic practices regarding androgen deficiency in ageing men.
