A testosterone level test measures the amount of testosterone in the blood. Testosterone is an androgen, or a sex hormone, produced by both males and females. It plays a role in puberty and fertility. It also affects sexual desire.
The hormone testosterone (T) is often associated with masculinity. However, women’s bodies also make testosterone. Too little testosterone in men or too much in women can indicate serious health problems. It can also create traits that are considered abnormal for your biological sex. That’s why this test is recommended to check the level of testosterone.
A normal testosterone-level range for men is 300 to 1,000 nanograms per deciliter (ng/dL). For women, it’s between 15 and 70 nanograms per deciliter.
