This study looks like a new analysis of the results of the placebo controlled testosterone trials. The abstract says:
788 men ≥65 years old with an average of two serum testosterone levels <275 ng/dL were prescribed testosterone gel, the dose adjusted to maintain the testosterone level in the normal range for young men, or placebo gel for 12 months. Testosterone treatment for one year of older men with low testosterone was associated with small reductions in cholesterol and insulin but not with other glucose markers or markers of inflammation or fibrinolysis or with troponin.
