Testosterone levels in males and females ; Total testosterone Stage Age range Male Female Values SI units Values SI units ; Infant: Premature (26–28 weeks) 59–125 ng/dL: 2.047–4.337 nmol/L
100–200 pg/mL <55 ng/dL [4] Callen-Lorde: United States "Some guidelines recommend checking estradiol and testosterone levels at baseline and throughout the monitoring of estrogen therapy. We have not found a clinical use for routine hormone levels that justifies the expense.
20–81 ng/dL Estrone: Follicular phase 110 μg/day 80 μg/day 2200 L/day 110–400 pmol/L 30–110 pg/mL Luteal phase 260 μg/day 150 μg/day 2200 L/day 310–660 pmol/L 80–180 pg/mL Postmenopause 40 μg/day Insignificant 1610 L/day 22–230 pmol/L 6–60 pg/mL Estradiol: Follicular phase 90 μg/day 80 μg/day 1200 L/day <37–360 pmol/L
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 ...
20–81 ng/dL Estrone: Follicular phase 110 μg/day 80 μg/day 2200 L/day 110–400 pmol/L 30–110 pg/mL Luteal phase 260 μg/day 150 μg/day 2200 L/day 310–660 pmol/L 80–180 pg/mL Postmenopause 40 μg/day Insignificant 1610 L/day 22–230 pmol/L 6–60 pg/mL Estradiol: Follicular phase 90 μg/day 80 μg/day 1200 L/day <37–360 pmol/L
For example, on a certain monitor, the horizontal distance between the upper limits for parathyroid hormone in pmol/L and pg/mL may be 7 cm, with the mass concentration to the right. A molar concentration of, for example, 5 pmol/L would therefore correspond to a mass concentration located 7 cm to the right in the mass diagram, that is ...
This is because testosterone levels in men are about 100 to 1,000 times higher than estradiol levels in women (300 to 1,000 ng/dL vs. 50 to 150 pg/mL, respectively). [50] Non-scrotal testosterone patches were assessed and were found to be ineffective in raising testosterone levels in men. [ 50 ]
In another study, a dosage of 1 mg/day oral micronized estradiol in healthy older men, which increased circulating estradiol levels by a relatively high amount of 6-fold (to 159 pg/mL), estrone levels by 15-fold (to 386 pg/mL), and SHBG levels by 17%, was found to suppress total testosterone levels by 27% (to 436 ng/dL) and free testosterone ...
