Did treatment with gel testosterone help improve cognitive function and memory in men aged 65 years and older diagnosed with low testosterone and age-related memory impairment?

The Cognitive Function Trial, part of the larger, placebo-controlled Testosterone Trials, attempted to answer this question. Results were published in JAMA.
