Hone Health reports on the factors responsible for testosterone levels in men and how they are affected by age and lifestyle.
In women with polycystic ovary syndrome (PCOS), a condition of androgen excess, testosterone levels are typically around 50 to 80 ng/dL, with a range of about 30 to 140 ng/dL. [ 9 ] [ 10 ] [ 7 ] Total testosterone levels are about 20-fold and free testosterone levels about 40-fold higher in men than in women on average. [ 11 ]
