Testosterone is a vital hormone that plays a key role in male sexual and reproductive health. It is the principle male sex hormone that is responsible for the proper development of male sexual characteristics.
Testosterone is produced primarily in the testicles, with a small amount produced in the adrenal glands. It stimulates the development of secondary male sex characteristics during puberty, such as:
- Deepened voice
- Growth of body hair, especially pubic, facial, and body hair
- Increased muscle mass and strength
- Growth of bones and closing of bone growth plates
- Penis and testicle growth
Later in life, testosterone regulates:
- Sex drive (libido)
- Production of sperm
- Distribution of body fat
- Bone strength and density
Having optimal levels of this important hormone leads to improved energy, strength, stamina, cognitive abilities, and an overall sense of vitality.
Conversely, low testosterone (
hypotestosteronism) can cause symptoms like:
- Diminished sex drive and erectile dysfunction
- Decreased muscle mass and strength
- Loss of body and facial hair
- Depression and mood changes
Causes for low testosterone levels include:
- Normal aging
- Injury or infection of the testes
- Chemotherapy or radiation treatments
- Chronic illnesses
- Obesity
If you're experiencing symptoms of low testosterone, see your doctor to get your testosterone levels tested. They can determine if testosterone therapy or lifestyle changes may help get your levels back into the healthy range again.
