The American College of Physicians (ACP) released new guidelines regarding testosterone replacement therapy (TRT). The advice is that TRT should only be prescribed to treat sexual dysfunction in men with age-related decline in hormone levels.

The ACP says there’s insufficient evidence that TRT improves anything more than sexual function.

Experts emphasize that until more research is done showing long-term benefits, it’s best to avoid using TRT for symptoms like energy, vitality, physical function, or cognition.
