Testosterone is often considered a male hormone, but it's also present in women and plays a crucial role in their overall health. While women have much lower levels of testosterone compared to men, it's essential to understand what constitutes normal testosterone levels in women. In this article, we'll delve into the specifics of testosterone in women, its functions, and what constitutes normal levels.
Testosterone is a steroid hormone produced by the ovaries and adrenal glands in women. It contributes to various bodily functions, including the development of bone density, muscle mass, and libido. Although women have lower testosterone levels than men, it's still vital for their reproductive health and overall well-being.
What Are Normal Testosterone Levels in Women?
Normal testosterone levels in women vary depending on factors such as age, menstrual cycle phase, and individual health status. Generally, testosterone levels in women range from 0.2 to 0.7 ng/mL (nanograms per milliliter). However, this range can fluctuate throughout the menstrual cycle and during different stages of life.
According to the Endocrine Society, the normal range for testosterone levels in women is:
| Age Group | Testosterone Level (ng/mL) |
|---|---|
| Pre-menopausal women | 0.2-0.7 |
| Post-menopausal women | 0.1-0.5 |
