Phytoestrogens are not essential nutrients because their absence from the diet does not cause a disease, nor are they known to participate in any normal biological function. [2] Common foods containing phytoestrogens are soy protein, beans, oats, barley, rice, coffee, apples, carrots (see Food Sources section below for bigger list).
That left people concerned that phytoestrogens, like those found in soy, would put you at increased risk of breast cancer, as estrogen activity can act as a catalyst for cancer growth.
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).

Gynecomastia is thought to be caused by an altered ratio of estrogens to androgens mediated by an increase in estrogen action, a decrease in androgen action, or a combination of these two factors. [7] Estrogen and androgens have opposing actions on breast tissue: estrogens stimulate proliferation while androgens inhibit proliferation.
Increase time to discharge in people with lifelong PE The good news is that even a few minutes per day of pelvic floor exercises can make a difference. Kegel exercises are a popular type of pelvic ...
Men with aromatase deficiency and estrogen insensitivity syndrome, and hence estrogen deficiency, appear to have normal sexual desire, function, and activity. [22] [21] However, estradiol supplementation in some men with aromatase deficiency increased sexual desire and activity but not in other men with aromatase deficiency.
Equol (4',7-isoflavandiol) is an isoflavandiol [1] estrogen metabolized from daidzein, a type of isoflavone found in soybeans and other plant sources, by bacterial flora in the intestines. [2] [3] While endogenous estrogenic hormones such as estradiol are steroids, equol is a nonsteroidal estrogen. Only about 30–50% of people have intestinal ...
Aromatase (EC 1.14.14.14), also called estrogen synthetase or estrogen synthase, is an enzyme responsible for a key step in the biosynthesis of estrogens. It is CYP19A1 , a member of the cytochrome P450 superfamily, which are monooxygenases that catalyze many reactions involved in steroidogenesis .
