Most people associate testosterone with men. It’s true that this vital hormone drives the development of the male brain and is responsible for the deep voice, facial hair, and many other features we associate with maleness. But women produce and need testosterone too (just as men have some estrogen), just in smaller amounts.
In both men and women, testosterone helps protect the nervous system and wards off depression, cognitive impairment, and Alzheimer’s disease. The aging process, however, can leave some men with low testosterone levels that have been shown to increase symptoms of anxiety and depression, as well as a host of other issues.
