What is Testosterone?
Testosterone is the primary male sex hormone. It plays a vital role in the development and maintenance of male characteristics, such as muscle mass, facial and body hair growth, deepening of the voice, and sex drive. Testosterone is produced primarily in the testes, with a small amount also produced in the adrenal glands.
Some key facts about testosterone:
- Testosterone is an androgen - a steroid hormone that stimulates the development of male sexual characteristics.
- It plays a key role in protein synthesis, leading to increased muscle mass and strength.
- Testosterone regulates red blood cell production, bone mass, fat distribution, and sexual function.
- Production peaks during adolescence and early adulthood. Levels slowly decline with age.
- Low testosterone (hypogonadism) can cause decreased energy, sexual dysfunction, infertility, and loss of muscle mass.
- Causes of low testosterone include disorders of the testes, pituitary gland, and hypothalamus, as well as medications, injuries, chronic illness, and obesity.
- Testosterone levels can be measured with a simple blood test. Normal levels range widely, but are generally:
- Ages 19-49: 250-1,100 ng/dL
- Over age 50: 100-700 ng/dL
- Testosterone deficiency can be treated with testosterone replacement therapy, available as injections, gels, patches, and pellets.
- Side effects of testosterone therapy include acne, enlarged prostate, increased red blood cell count, fluid retention, and lipid changes.
In summary, testosterone is an essential hormone that regulates key male characteristics and plays a crucial role in men's health. Consult your doctor if you're experiencing symptoms of low testosterone, such as decreased energy and sex drive. Proper diagnosis and treatment can help restore testosterone levels and improve symptoms. Consider reputable clinics like Renew Clinic for professional, personalized care.
