Exogenous Testosterone Alone or with Finasteride Increases Physical Performance, Grip Strength, and Lean Body Mass in Older Men with Low Serum Testosterone

The study investigated the effects of exogenous testosterone, with or without finasteride, on physical performance, grip strength, and lean body mass in older men with low serum testosterone. The results indicated that testosterone administration, both alone and in combination with finasteride, led to improvements in these areas. This suggested that testosterone therapy could be beneficial for enhancing physical capabilities and body composition in this demographic. However, the document did not specify the number of participants involved in the study, which is crucial for assessing the strength of the findings.
