Older Men With Low Levels of Testosterone

Assistant professor, Dr. Gail Laughlin, from the University of California San Diego notes, "This is the first report linking low levels of testosterone with earlier death in relatively healthy older men. We want to emphasize that this is an observational study and we cannot recommend that any man take testosterone based on these results. Only randomized clinical trials can determine whether testosterone supplements are safe and can promote longevity. In the meantime, lifestyle changes to prevent or decrease obesity may also extend longevity."

Low testosterone levels are often accompanied by symptoms such as low bone and muscle mass, increased fat mass, low energy, impaired physical, sexual, and cognitive function. Approximately 30 percent of men aged 60 years and older are afflicted with decreased testosterone levels.
