Serum testosterone levels naturally begin to decline gradually with age, but not necessarily to levels below those considered normal for healthy young men. In the NIH-sponsored Testosterone Trials, researchers evaluated the effects of testosterone therapy in 790 men aged 65 years or older with low testosterone and symptoms possibly attributable to low testosterone. In the studies, which were conducted at 12 sites across the country, researchers randomly assigned participants to therapy with testosterone gel or placebo gel, applied daily to the skin. They then measured serum testosterone levels in the participants at 1, 2, 3, 6, 9 and 12 months.
