Mass concentration (g/dL or g/L) is the most common measurement unit in the United States. Is usually given with dL (decilitres) as the denominator in the United States, and usually with L (litres) in, for example, Sweden.
35-39 years old: 352-478 ng/dL. 40-44 years old: 350-473 ng/dL. Although the American Urological Association (AUA) defines low testosterone as a total testosterone level of less than 300 ng/dL, it ...
Levels are normally 30–200 ng/dL (1.0–7.0 nmol/L) in females and 40–150 ng/dL (1.4–5.2 nmol/L) in males. In premature infants, serum androstenedione levels hover between 80 and 446 ng/dL. In full-term newborns, levels range from 20 to 290 ng/dL, and between 1 month and 1 year old, serum levels typically stay at less than 69 ng/dL.
Total levels of testosterone in the body have been reported as 264 to 916 ng/dL (nanograms per deciliter) in non-obese European and American men age 19 to 39 years, [197] while mean testosterone levels in adult men have been reported as 630 ng/dL. [198]
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]
