Testosterone (TT) [Saliva]

Testosterone (TT)
  • Builds muscle and promotes muscle tone
  • Increases libido
  • Helps strengthen bones
  • Reduces depression
  • Protects against heart disease

Testosterone (TT) is produced mainly by the testes in men, the ovaries in women and the adrenal glands in both sexes. Testosterone is synthesised from androstenedione, a metabolite of DHEA and progesterone.

Throughout most of the reproductive years, approximately 10-20 times more testosterone is produced in men than in women. At puberty males have much higher levels of testosterone, which is responsible for the development of male external genitalia and secondary hair patterns, stimulation of spermatogenesis and stimulation of anabolic activity leading to increased muscle mass and behavioural changes. In pubescent females, testosterone effects are more subtle but equally important for proper musculo-skeletal development, general anabolic activity and libido. In both sexes testosterone increases protein synthesis. Testosterone decreases with age in both men and women.
