Levels of testosterone and other androgens can be measured with a blood test. In women, normal testosterone levels range from 15 to 70 nanograms per deciliter (ng/dL) of blood.
Testosterone levels lower than 15 ng/dL may cause:
changes in breast tissue
fertility problems
low sex drive
missed or irregular menstrual periods
osteoporosis
vaginal dryness
Testosterone levels higher than 70 ng/dL may lead to:
acne
blood sugar problems
excessive hair growth, usually on the face
infertility
lack of menstruation
obesity
polycystic ovary syndrome (PCOS)
