Testosterone
Testosterone is an important hormone that plays many key roles in the human body. This steroid hormone is primarily secreted in the testes of males and the ovaries of females, with small amounts also secreted by the adrenal gland.
Some key facts about testosterone:
- It is the primary male sex hormone and is responsible for the proper development of male sexual characteristics. Testosterone levels peak during adolescence and early adulthood when the testes are most active.
- In males, the hormone regulates libido, fat distribution, muscle mass, red blood cell production, and maintenance of bone density. It also plays a role in mood, aggression, and cognition.
Normal total testosterone levels in adult males typically range from 300 to 1,000 ng/dL with free testosterone levels of 5 to 20 pg/mL. Levels decline naturally as men age.
- In females, small amounts of testosterone are produced by the ovaries and adrenal glands. The hormone plays a role in libido, muscle mass, bone density, and cognition in women as well.
Some key uses and supplements include:
- Testosterone therapy can be used to treat hypogonadism and certain types of infertility in men. Supplementing testosterone is also sometimes used by athletes or elderly men to try to increase muscle mass and bone density.
- However, artificial supplementation carries health risks if not properly monitored by a physician. Excess testosterone, especially when combined with strength training, has been linked to aggression, liver toxicity, heart disease, and infertility issues.
