High estrogen is typically defined as “levels exceeding the normal range” for a specific age and menstrual phase, often accompanied by other symptoms (more on this soon), she says.
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). [14]
During the reproductive years of human females, levels of estradiol are somewhat higher than that of estrone, except during the early follicular phase of the menstrual cycle; thus, estradiol may be considered the predominant estrogen during human female reproductive years in terms of absolute serum levels and estrogenic activity.
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.

Androgens (e.g. testosterone) are only present in small quantities. In men, testosterone, an androgen, dominates, and estrogen is only present to a small extent.
Estradiol (E2) is a medication and naturally occurring steroid hormone. [11] [12] [13] It is an estrogen and is used mainly in menopausal hormone therapy and to treat low sex hormone levels in women.
