Let’s Start With the Problem
Testosterone is the main sex hormone found in men. It controls male physical features. The testes (testicles) make testosterone. Women have testosterone, too, but in much smaller amounts than in men. The brain and pituitary gland, a small gland at the base of the brain, control production of testosterone by the testes. From there, testosterone moves through our blood to do its work. Your testosterone levels change from hour to hour. They tend to be highest in the morning and lowest at night. Unlike women, who experience a rapid drop in hormone levels at menopause, men experience a more gradual decrease of testosterone levels over time. For many reasons, testosterone can become—and stay—too low. Less often, testosterone levels can become too high. When this hormone is not in balance, health problems can result.
