Estrogen is associated with edema, including facial and abdominal swelling. Melanin. Estrogen is known to cause darkening of skin, especially in the face and areolae. [38] Pale skinned women will develop browner and yellower skin during pregnancy, as a result of the increase of estrogen, known as the "mask of pregnancy". [39]
Earlier research has indicated that natural estrogens can help protect the brain from oxidative harm. This current study aims to explore how different estrogen metabolites produced by the body can guard against neurotoxicity caused by oxidation, both in lab settings and in live subjects.
Furthermore, estrogen monitoring during fertility therapy assesses follicular growth and is useful in monitoring the treatment. Estrogen-producing tumors will demonstrate persistent high levels of estradiol and other estrogens. In precocious puberty, estradiol levels are inappropriately increased.
Conjugated estrogens (brand name Premarin), an estrogen product manufactured from the urine of pregnant mares and commonly used in menopausal hormone therapy, is a mixture of natural estrogens including estrone sulfate and equine estrogens such as equilin sulfate and 17β-dihydroequilin sulfate. [1]
Compared to previous bioidentical formulas that only used estradiol, he promoted a triple-estrogen formula called Triest, which combined three estrogens found in human females: estriol, estradiol and estrone. It was based on an unpublished study whose conclusions did account for how estrogens are processed and excreted in the body ...
Estrone is an estrogen, specifically an agonist of the estrogen receptors ERα and ERβ. [1] [5] It is a far less potent estrogen than is estradiol, and as such, is a relatively weak estrogen. [1] [5] [6] Given by subcutaneous injection in mice, estradiol is about 10-fold more potent than estrone and about 100-fold more potent than estriol. [7]
There are two variants of the estrogen receptor, alpha and beta and many phytoestrogens display somewhat higher affinity for ER-β compared to ER-α. [ 14 ] The key structural elements that enable phytoestrogens to bind with high affinity to estrogen receptors and display estradiol-like effects are: [ 2 ]
Estradiol is a naturally occurring and bioidentical estrogen, or an agonist of the estrogen receptor, the biological target of estrogens like endogenous estradiol. [11] Due to its estrogenic activity, estradiol has antigonadotropic effects and can inhibit fertility and suppress sex hormone production in both women and men.
