When doctors measure testosterone as an important male hormone in women, it’s measured in the early-morning hour or in the early part of the menstrual cycle. This is because testosterone levels change throughout the menstrual cycle by almost 25%. Women also have the highest levels in the morning, due to changes throughout the day in circulating levels of testosterone.

Doctors can also measure free testosterone, which represents the amount of testosterone that is biologically active. This requires a specific blood test in certain laboratories that have assays developed to measure low amounts of free testosterone in a consistent and reproducible manner.
