[64] [68] [69] Although contradictory reports exist, one study found mean integrated estradiol levels of 150 pg/mL in younger women whereas mean integrated levels ranged from 50 to 120 pg/mL in older women.

The four major naturally occurring estrogens in women are estrone (E1), estradiol (E2), estriol (E3), and estetrol (E4). Estradiol (E2) is the predominant estrogen during reproductive years both in terms of absolute serum levels as well as in terms of estrogenic activity.
Signs of hyperestrogenism may include heightened levels of one or more of the estrogen sex hormones (usually estradiol and/or estrone), lowered levels of follicle-stimulating hormone and/or luteinizing hormone (due to suppression of the hypothalamic–pituitary–gonadal axis by estrogen), and lowered levels of androgens such as testosterone (generally only relevant to males). [1]
[93] [94] Moreover, whereas normal physiological estrone sulfate levels are 10 to 25 times higher than those of estradiol and estrone in premenopausal women, [95] levels of estrone sulfate with oral estradiol are an additional 8 to 20 times higher than normal premenopausal or postmenopausal estrone sulfate levels.
Levels of estriol increase 1,000-fold during pregnancy, [8] whereas levels of estradiol and estrone increase 100-fold, [12] and estriol accounts for 90% of the estrogens in the urine of pregnant women. [5] At term, the daily production of estriol by the placenta is 35 to 45 mg, [12] and levels in the maternal circulation are 8 to 13 ng/dL. [3]
