What is the Normal Testosterone Level for a 70-Year-Old Man? 156–819 ng/dL The researchers also broke the data down into normal levels of free testosterone and bioavailable testosterone.
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."
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 ...
Blood for the test must be taken in the morning hours, when levels are highest, as levels can drop by as much as 13% during the day and all normal reference ranges are based on morning levels. [9] [10] Normal total testosterone levels depend on the man's age but generally range from 240 to 950 ng/dL (nanograms per deciliter) or 8.3–32.9 nmol ...
Testosterone levels increase in adolescence after puberty and into early adulthood, and naturally decline over time, usually starting in a man’s 40s or fifties. However, this drop now seems to ...
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]
So-called normal levels of testosterone are approximations, but can help researchers investigate disease and treatments. So-called normal levels of testosterone are approximations, but can help ...
