Testosterone Total+Free near me in Meerut

The Testosterone Total test measures the level of testosterone hormone available in the blood. This includes two forms of testosterone: free testosterone and bound testosterone. Bound testosterone is attached to proteins, mainly to sex hormone-binding globulin (SHBG) and albumin. It cannot enter the body's cells or directly affect tissues and organs. Instead, it acts as a store of testosterone in the blood and can be released when the body needs it. Free testosterone is not attached to any proteins and is the active form. It can easily transport to various tissues, and affects key functions like sex drive, muscle growth, bone strength, and energy levels.

Testosterone free measures the levels of free testosterone present in the blood. 

Testosterone is a sex hormone which is mainly found in men. It can also be found in women but in small amounts. Testosterone helps in the development of male physical characteristics. 

In men, testosterone is produced by the Leydig cells present in the testicles. It is also produced by the adrenal glands present in both males and females. In females, small amounts of testosterone are produced by the ovaries. 

The function of testosterone is to develop secondary sex characteristics which include enlargement of the penis, body hair growth, development of muscle, and deepening of the voice. During puberty, it is produced in large amounts in males. In adult males, its function is to regulate the sex drive and to maintain muscle mass. In adult females, the testosterone gets converted to estradiol, which is the main sex hormone in females.

The testosterone hormone production is regulated by luteinizing hormone (LH), which is produced by the pituitary gland. As the levels of testosterone rise, the production of LH decreases which in turn slows down the production of testosterone. This is due to the negative feedback system, in which one entity controls the production of others. Similarly, when the levels of testosterone fall, it leads to an increase in production of LH which stimulates testosterone production.

The levels of testosterone are highest in the early morning and lowest in the evening. With exercise, the levels of testosterone increase and with age the levels decrease. 

In the blood, about two-thirds of testosterone hormone is bound to sex-hormone-binding globulin (SHBG) and about one-third is bound to albumin. A small amount is present as free testosterone.
