Treatment with testosterone may help heart failure patients feel better and exercise more, preliminary research shows. The finding comes from four small studies of people with heart failure. The researchers analyzed the results from all of those studies and found that those who took testosterone supplements were able to exercise longer than those who didn't. Testosterone occurs naturally in men and women. But testosterone levels decline with age, which can contribute to decreases in muscle mass and strength.
