Testosterone is a vital male hormone that is responsible for the development and maintenance of male attributes. Women also have testosterone, but in much smaller amounts. The hypothalamus is the decision-maker.
A testosterone test checks the level of this male hormone (androgen) in the blood. Testosterone affects sexual features and development. In men, it is made in large amounts by the testicles . In both men and women, testosterone is made in small amounts by the adrenal glands , and in women, by the ovaries . The pituitary gland controls the level of testosterone in the body. When the testosterone level is low, the pituitary gland releases a hormone called luteinizing hormone (LH). This hormone tells the testicles to make more testosterone. Before puberty, the testosterone level in boys is normally low. Testosterone increases during puberty. This causes boys to develop a deeper voice, get bigger muscles, make sperm , and get facial and body hair. The level of testosterone is the highest around age 40, then gradually becomes less in older men.
