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.
Estradiol levels with 50 to 100 μg/day transdermal estradiol patches applied to the forearm and to the scrotum in a crossover study in 2 men with prostate cancer. [14] In 35 men treated continuously with one 100 μg/day estradiol patch scrotally, the mean estradiol level was ~500 pg/mL (range ~125–1,200 pg/mL).
190–341 pg/mL Postmenopause 6 μg/day Insignificant 910 L/day <37–140 pmol/L 10–38 pg/mL Estrone sulfate: Follicular phase 100 μg/day Insignificant 146 L/day 700–3600 pmol/L 250–1300 pg/mL Luteal phase 180 μg/day Insignificant 146 L/day 1100–7300 pmol/L 400–2600 pg/mL Progesterone: Follicular phase 2 mg/day 1.7 mg/day 2100 L/day
Circulating levels are typically between 130 and 200 pg/mL at this time, but in some women may be as high as 300 to 400 pg/mL, and the upper limit of the reference range of some laboratories are even greater (for instance, 750 pg/mL).
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 ...
190–341 pg/mL Postmenopause 6 μg/day Insignificant 910 L/day <37–140 pmol/L 10–38 pg/mL Estrone sulfate: Follicular phase 100 μg/day Insignificant 146 L/day 700–3600 pmol/L 250–1300 pg/mL Luteal phase 180 μg/day Insignificant 146 L/day 1100–7300 pmol/L 400–2600 pg/mL Progesterone: Follicular phase 2 mg/day 1.7 mg/day 2100 L/day
A study of pseudopregnancy with intramuscular injections of 40 mg/week estradiol valerate and 250 mg/week hydroxyprogesterone caproate in women with estrogen deficiency observed estradiol levels of about 3,100 pg/mL at 3 months of therapy and 2,500 pg/mL at 6 months of therapy.
Estradiol levels are 1,000 to 5,000 pg/mL during the first trimester, 5,000 to 15,000 pg/mL during the second trimester, and 10,000 to 40,000 pg/mL during the third trimester, [38] with a mean of 25,000 pg/mL at term and levels as high as 75,000 pg/mL measurable in some women. [39] Levels of progesterone are 10 to 50 ng/mL in the first ...
