What Is the Normal Testosterone Level in Women?

Since testosterone in women is primarily derived from the conversion of androgens secreted by the ovaries and adrenal glands, female testosterone levels may fluctuate over time. So what constitutes a normal testosterone level in women?

What Is the Normal Testosterone Range in Women?

The normal testosterone range is 0.1–0.75 ng/mL. As the body’s primary sex hormone, testosterone is produced in both men and women. However, men produce 20–30 times more testosterone than women, playing a critical role in maintaining secondary sexual characteristics, bone density, and muscle strength.

In women, testosterone is mainly secreted by the ovaries and adrenal cortex. Excessively elevated levels warrant evaluation for conditions such as polycystic ovary syndrome (PCOS) or adrenal cortical tumors. Adrenal cortical tumors require diagnosis via CT or MRI and are typically treated surgically. Hormone levels rarely exceed twice the upper limit of the normal range. Levels more than double the normal upper limit may suggest specific disorders—most commonly PCOS. In such cases, treatment aims to lower testosterone—or more broadly, reduce androgen activity.

If testosterone levels fall within the normal range, menstrual cycles are regular, and pelvic ultrasound reveals no features suggestive of PCOS, no specific intervention is required. Maintaining healthy dietary and lifestyle habits is recommended—such as consuming plenty of fresh vegetables and fruits while minimizing intake of spicy or irritating foods.
