Testosterone, Serum

Testosterone is the primary male sex hormone that influences the development of secondary sexual characteristics and supports sexual function. The testosterone test helps diagnose Hormonal imbalances, Infertility, and erectile dysfunction.
Testosterone function: Testosterone is the primary male sex hormone, produced mainly in the testes in men and in smaller amounts in the ovaries in women. It is responsible for the development of secondary sexual characteristics, such as muscle growth, body hair, voice changes, and sexual function maintenance. In women, testosterone helps regulate muscle mass and bone density.
Test significance: The testosterone test is used to diagnose Hormonal imbalances such as Hypogonadism, Infertility, low libido, and erectile dysfunction in men. In women, this test can help diagnose Hyperandrogenism and Polycystic Ovary Syndrome (PCOS). Testosterone levels are also useful in evaluating hormonal balance during hormone replacement therapy.
Diseases: Elevated testosterone levels in women may indicate Hyperandrogenism or PCOS, while low levels in men may be related to Hypogonadism, Testicular Dysfunction, or age-related decline.
