Free and total testosterone test checks the level of this 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 also 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 between ages 30-40, and then gradually decreases as we get older.
In women, the ovaries account for half of the testosterone in the body. Women have a smaller amount of testosterone in their bodies compared to men. But testosterone plays an important role throughout the body in both men and women. It affects the brain, bone and muscle mass, fat distribution, the vascular system, energy levels, genital tissues, sexual functioning and libido.
Most of the testosterone in the blood is bound to a protein called sex hormone binding globulin (SHBG). Testosterone that is not bound or “free” must also be checked if a man or a woman is having sexual problems.
Why is testosterone so important? testosterone is notorious for its role in sexual function, in addition to helping build muscle mass, maintain bone density and regulate hair growth. It is derived from cholesterol (like all the sex hormones) and its immediate precursor is DHEA (dehydroepiandrosterone). DHEA should also be found in youthful levels in the aging bodies of men and women. .
