Testosterone test is carried out to examine the levels of male hormone in the blood. Testosterone is a male hormone (androgen) that affects sexual features and development. It is produced in large amounts by the testicles. Before puberty, the testosterone level in boys is low. An increase in testosterone during puberty causes sex organs to mature, sperm to be produced, sexual features to develop, including facial and body hair, enlarged muscles, and a deep voice. The level of testosterone continues to rise during adulthood until it peaks around age 40, then it gradually decreases.
Elevated levels of free and weakly bound testosterone are observed in female hirsutism (unwanted hair growth). In males, decreased blood concentrations are associated with hypogonadism (under-functioning of the testes). Decreased levels have been associated with diminished sex drive and loss of bone density.
Total testosterone levels in women decrease by approximately 30% after menopause. Taking estrogens also may affect testosterone levels.
The release of testosterone is controlled by a hormone called luteinizing hormone, or LH, which is produced by the pituitary gland. When the testosterone level is low, the pituitary gland releases LH, which increases the amount of testosterone produced by the testicles. In women and men, testosterone is also produced in small amounts by the adrenal glands, and, in women, by the ovaries.
If you are considering taking anti-aging medicines such as Human Growth Hormone (HGH) or steroids like Testosterone, going through a Testosterone test to know your Testosterone levels can help you and your doctor understand if you should be taking these drugs or not.
