Testosterone is the principal androgen of which 95% is made by the testes (testicles or sperm producers), 5% in the adrenals of both sexes and 1% by female ovaries. T is synthesized from cholesterol at approximately 6 mg/day (normal range 5-11 mg/day depending on age) and metabolized by the liver and excreted in the urine. Testosterone can be bioconverted into two other steroids at target tissues throughout the body: This conversion essentially regulates all T activity since the rate of conversion can be modified by the levels of these steroids.
