Reference Table for Normal Testosterone Levels in Women

Testosterone is an androgen present in the female body. Both men and women produce testosterone, and women do have testosterone. Serum testosterone levels are measured via venous blood testing. In women, testosterone is primarily produced by two key organs: the ovaries and the adrenal glands. So, what are the normal reference ranges for testosterone in women?

Normal Reference Range for Testosterone in Women

In women, a serum testosterone level of 0.1–0.75 ng/mL falls within the normal range. Testosterone is a major sex hormone secreted by both sexes. Men produce approximately 20–30 times more testosterone than women, and this hormone plays a critical role in maintaining secondary sexual characteristics, as well as bone and muscle strength.

In women, testosterone is mainly secreted by the ovaries and the adrenal cortex. Excessively elevated testosterone levels may indicate underlying conditions such as polycystic ovary syndrome (PCOS) or adrenal cortical tumors. Adrenal cortical tumors require diagnosis via computed tomography (CT) and magnetic resonance imaging (MRI), and surgical intervention is typically necessary. Testosterone also exerts significant effects on brain function, behavior, and mood. Elevated testosterone levels are commonly associated with PCOS, whose initial presentation often includes infertility; patients should seek evaluation and management in endocrinology or obstetrics and gynecology departments.

Low testosterone levels can impair immune function and lead to symptoms such as palpitations, irritability, fatigue, and lethargy. They may also contribute to osteoporosis. We hope this information has been helpful!
