What is testosterone?
Testosterone is a crucial hormone that plays many key roles in the human body. Primarily seen as the "male" hormone, testosterone is responsible for the development of typically male characteristics like facial and body hair growth, increased muscle mass and strength, and deepening of the voice. However, testosterone is important for both men and women.
Some key facts about testosterone:
- Testosterone is an androgen, meaning it is responsible for the development and maintenance of "male" traits. However, women's bodies produce testosterone in the ovaries and adrenal glands, just in smaller amounts than men.
- In men, testosterone is produced mainly in the testes. The pituitary gland in the brain controls testosterone production by releasing luteinizing hormone (LH), which signals the testes to produce testosterone.
- Levels of testosterone peak during adolescence and early adulthood when the body is developing. After age 30, testosterone levels begin to decline slowly in men.
- Having optimal levels of testosterone is important for energy, sex drive, muscle mass, mood regulation, cognitive function, and more in both men and women. Too much or too little testosterone can cause health issues.
Some key functions of testosterone in the body:
- Muscle growth - Testosterone increases muscle protein synthesis, leading to increased muscle mass and strength, especially when combined with strength training. This is why some athletes or bodybuilders misuse anabolic steroids, which mimic testosterone.
- Bone density - Testosterone promotes mineralization and growth of bones, helping reach peak bone mass and strength during puberty. Declining testosterone is linked to osteoporosis in older men.
- Fat distribution - Testosterone helps regulate where the body stores fat. Men tend to accumulate fat in the abdomen due to testosterone, while women store fat in hips/thighs.
- Red blood cell production - Testosterone promotes bone marrow to produce red blood cells. It explains higher hemoglobin levels in men.
- Sex drive and function - Testosterone directly impacts libido and erectile function in men. Declines can affect sexual health and performance.
- Mood and cognition - Testosterone plays a role in confidence, motivation, competitiveness, and cognition. Low testosterone is linked to depression and reduced cognitive function.
