Testosterone, total Refs Endocrine Society: United States: 100–200 pg/mL <50 ng/dL [1] World Professional Association for Transgender Health (WPATH) United States "[T]estosterone levels [...] below the upper limit of the normal female range and estradiol levels within a premenopausal female range but well below supraphysiologic levels."
Testosterone is an important hormone. It helps men develop during puberty, and as they age, it plays a critical role in helping control fat levels, cholesterol, and glucose levels.
With immunoassay-based techniques, testosterone levels in premenopausal women have been found to be about 40 ng/dL (1.4 nmol/L) and DHT levels about 10 ng/dL (0.34 nmol/L). [5] [74] With radioimmunoassays, the ranges for testosterone and DHT levels in women have been found to be 20 to 70 ng/dL and 5 to 30 ng/dL, respectively. [74]
Typically, testosterone levels in men are around 15 times higher than in women. In both women and men, it’s normal for testosterone levels to drop with age — starting at about age 30 in men ...
Conversely, “with too much testosterone, women often have acne, too much hair on the body, hair loss on the head, high blood pressure, elevated cholesterol, skipped cycles, or problems ...
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]
The free androgen index is intended to give a guide to the free testosterone level, but it is not very accurate (especially in males — see endocrine society commentary below). Consequently, there are no universally agreed 'normal ranges', and levels slightly above or below quoted laboratory reference ranges may not be clinically significant.
