Testosterone, Total, Males (Adult), Immunoassay

Categories: ,
Testosterone is the primary sex hormone in men that is responsible for the development of male sexual characteristics. It is produced in the Leydig cells of the male testicles. It is also secreted by the adrenals in both males and females; however in minimal amounts by the ovaries in females. In women, testosterone is converted to estradiol which is considered as the main sex hormone in females. The testosterone blood test is used to measure the testosterone levels in the blood. This test is performed to diagnose various reproductive health problems such as erectile dysfunction, low sex drive, and infertility in men; and virilization or polycystic ovary syndrome in women. This test also helps in determining the cause of ambiguous genitalia.
