Testosterone is a hormone produced primarily in the testicles. Testosterone helps maintain men’s:
- Bone density
- Fat distribution
- Muscle strength and mass
- Red blood cell production
- Sex drive
- Sperm production
Testosterone is a steroid hormone produced in all humans, and is the main sex hormone in males. Testosterone plays a key role in maintaining physical and mental health in both females and males. Testosterone has been shown to enhance the cardiac benefits of exercise, builds lean muscle mass, sharpen your memory, increases the libido, decreases excess body fat, improve your energy level, along with an overall sense of well-being. It helps maintain bone density, fat distribution, red blood cell production, and sperm production.
Just like your cholesterol or blood pressure, there is a numerical range of testosterone levels (also known as T levels) that are considered normal. The brain and the testicles work together to keep testosterone in this range. When levels of testosterone are below normal, the brain signals the testicles to make more. When testosterone levels reach a normal level, the brain signals the testicles to make less.
What Happens To Your Testosterone Levels With Age?
Testosterone peaks during adolescence and early adulthood. As you get older, your testosterone level gradually declines — typically about 1 percent a year after age 30.
