Testosterone is a hormone commonly associated with men, but it is present in women as well. Testosterone is responsible for a range of functions in the female body, including regulating sex drive, muscle mass, and bone density.
The amount of testosterone a woman has varies throughout her life. Levels are typically highest during the reproductive years and decline after menopause. Women with higher levels of testosterone may have increased muscle mass, strength, and energy. They may also have a lower risk of osteoporosis and heart disease.
