Sərbəst testosteron

25 Azn

Free testosterone is the biologically active fraction of testosterone that is not bound to blood proteins.

Testosterone has anabolic effects on muscle tissue, supports bone development, regulates sebaceous gland activity, and participates in the synthesis of liver lipoproteins.
It modulates the synthesis of β-endorphins and insulin.
In men, testosterone plays a key role in the psychophysiological aspects of the reproductive system, secondary sexual characteristics, libido, spermatogenesis, potency, and sexual behavior.
In women, testosterone is involved in follicular regression in the ovaries and regulates gonadotropic hormone levels from the pituitary gland.
Why Measure Free Testosterone?
Free testosterone levels are independent of sex hormone-binding globulin (SHBG).
Therefore, measuring free testosterone is more informative than total testosterone, especially when SHBG levels are altered.

The analysis is performed on a blood sample drawn from a vein.
Stop eating8–14 hours before the test.
Before the test, avoid:
- Emotional and physical stress
- Alcohol consumption
Discontinue estrogen and androgen medications48 hours before testing.
Unless otherwise directed by a doctor, the test should be performed before 11:00 AM.
