Men experience sexual dysfunction at testosterone levels of below 300 ng/dL, with men that have levels of testosterone of approximately 200 ng/dL often experiencing such problems. [28] Complete loss of testicular testosterone production resulting in testosterone levels within the castrate range (95% decrease, to 15 ng/dL on average) with ...
Estradiol is an estrogen, or an agonist of the nuclear estrogen receptors (ERs), the estrogen receptor alpha (ERα) and the estrogen receptor beta (ERβ). [1] [2] [6] In one study, the EC 50 Tooltip half-maximal effective concentration value of estradiol for the human ERα was 50 pM (0.05 nM) and for the human ERβ was 200 pM (0.2 nM).
Gynecomastia in older men is estimated to be present in 24–65 percent of men between the ages of 50 and 80. Estimates on asymptomatic gynecomastia is about up to 70% in men aged 50 to 69 years. [26] [50] The prevalence of gynecomastia in men may have increased in recent years, but the epidemiology of the disorder is not fully understood. [40]

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.
Estetrol is a major estrogen in the body. [ 1 ] [ 2 ] In contrast to estrone and estradiol, estetrol is a native estrogen of fetal life. Estetrol is produced exclusively by the fetal liver [ 1 ] and is found in detectable levels only during pregnancy, with relatively high levels in the fetus and lower levels in the maternal circulation.
