Estradiol is not produced in the gonads only; in particular, fat cells produce active precursors to estradiol, and will continue to do so even after menopause. [51] Estradiol is also produced in the brain and in arterial walls. In men, approximately 15 to 25% of circulating estradiol is produced in the testicles.
[7] [5] [6] Estradiol acetate is an estrogen and hence is an agonist of the estrogen receptor, the biological target of estrogens like estradiol. [8] [9] It is an estrogen ester and a prodrug of estradiol in the body. [9] [8] Because of this, it is considered to be a natural and bioidentical form of estrogen. [9] [10]

While a 2018 review found that taking progesterone and estrogen together can decrease this risk, [47] other reviews reported an increased risk of blood clots and pulmonary embolism when estrogen and progestogen were combined, particularly when treatment was started 10 years or more after menopause and when the women were older than 60 years ...
High-dose estrogen therapy has been used successfully in the treatment of sexual deviance such as paraphilias in men. [ 45 ] [ 46 ] However, it has been found to produce many side effects (e.g., gynecomastia , feminization , cardiovascular disease , blood clots ), and so is no longer recommended for such purposes. [ 45 ]
Estrone is a naturally occurring and bioidentical estrogen, or an agonist of the estrogen receptor, the biological target of estrogens like endogenous estradiol. [5] It is a relatively weak estrogen, with much lower activity than estradiol. [5] However, estrone is converted in the body into estradiol, which provides most or all of its ...
These scores vary in direct proportion to estrogen levels throughout the menstrual cycle, pregnancy, and menopause. Furthermore, estrogens when administered shortly after natural or surgical menopause prevents decreases in verbal memory. In contrast, estrogens have little effect on verbal memory if first administered years after menopause. [60]
