Testosterone therapy didn't raise heart attacks or prostate cancer in a 5,200-man trial

In the TRAVERSE trial, 5,204 men aged 45 to 80 with low testosterone used testosterone gel or a placebo for about two years: heart attacks, strokes and heart deaths were 7.0% vs 7.3%, and prostate cancers were 12 vs 11.
