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 ...
A higher dosage of estradiol gel containing 1.5 mg estradiol per daily application has been found to produce mean estradiol levels of 40 to 100 pg/mL and estrone levels of 90 pg/mL, while 3 mg per day has been found to result in respective mean estradiol and estrone levels of 60 to 140 pg/mL and 45 to 155 pg/mL.

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).
In the normal menstrual cycle, estradiol levels measure typically <50 pg/mL at menstruation, rise with follicular development (peak: 200 pg/mL), drop briefly at ovulation, and rise again during the luteal phase for a second peak. At the end of the luteal phase, estradiol levels drop to their menstrual levels unless there is a pregnancy.
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.
Estrogen levels were dramatically and persistently elevated (estradiol levels were 2,340 pg/mL, regarded as being about 10 times the normal level, and ranged from 750 to 3,500 pg/mL), gonadotropin levels were mildly elevated (follicle-stimulating hormone and luteinizing hormone levels were 6.7–19.1 mIU/mL and 5.8–13.2 mIU/mL, respectively ...
Estrone has been used by intramuscular injection at a dosage of 0.1 to 2 mg per week, or 0.1 to 0.5 mg given 2 or 3 times per week, for the treatment of menopausal symptoms such as hot flashes and vaginal atrophy, [20] [21] and at a dosage of 0.1 to 1.0 mg weekly in single or divided doses for the treatment of female hypogonadism, surgical ...
Likewise, other studies found that levels of estradiol and estrone are very similar after oral administration of roughly equimolar doses of estradiol (1.5 mg) and estradiol valerate (2 mg). [110] [111] [112] A study of high-dose oral estradiol valerate found levels of estradiol of about 250 pg/mL after a single 10-mg dose in three women. [107]
