1. the most potent naturally occurring ovarian and placental estrogen in mammals; it prepares the uterus for implantation of the fertilized ovum and promotes the maturation of and maintenance of the female accessory reproductive organs and secondary sex characters.
2. a preparation of this hormone used in estrogen replacement therapy for conditions such as female hypogonadism, ovariectomy, or primary ovarian failure, and in treatment of abnormal uterine bleeding, vasomotor menopausal symptoms, postmenopausal osteoporosis, atrophic vaginitis, and certain advanced breast or prostatic carcinomas. Used most often in the form of estradiol cypionate, estradiol valerate, or ethinyl estradiol.
es·tra·di·ol (E2),(es-tră-dī'ol, es-tra'dē-ōl),
β-Estradiol; 17β-estradiol; the most potent naturally occurring estrogen in mammals, formed by the ovary, placenta, testis, and possibly the adrenal cortex; therapeutic indications for estradiol are those typical of an estrogen. α-Estradiol (17α-estradiol), exhibits considerably less biologic activity.
estradiol/es·tra·di·ol/ (es″trah-di´ol) (es-tra´de-ol) the most potent estrogen in humans; pharmacologically, it is often used in the form of its esters (e.g., e. cypionate, e. valerate ) or as a semisynthetic derivative (ethinyl e.) . For properties and uses, see estrogen.
estradiol(ĕs′trə-dī′ôl′, -ōl′, -ŏl′)
An estrogenic hormone, C18H24O2, that is produced by the ovaries and is the dominant naturally occurring estrogen in women between puberty and menopause. It is used to treat menopausal symptoms and other conditions.

estradiolE2 Endocrinology The most potent natural estrogen, produced chiefly by the ovary and in small amount by the testis; it is measured to evaluate postmenopausal status or suspected hypogonadism ↑ in Ovarian tumors, pregnancy, adrenal feminizing tumors, precocious puberty, liver disease, gynecomastia ↓ in OCs, ovarian failure, menopause, hypogonadism
The most potent naturally occurring estrogen, formed by the ovary, placenta, testes, and possibly the cortex of the suprarenal gland.
Most potent naturally occurring estrogen in mammals, formed by the ovary, placenta, testis, and possibly the cortex of the suprarenal gland.
the female steroid hormone produced by the mature ovarian follicle and the adrenal cortex and responsible for sexual receptivity at the time of estrus. Is the dominant estrogenic hormone in the nonpregnant animal. In the pregnant animal the dominant hormone is estrone; called also estradiol-17β; commercial products include estradiol benzoate and the cyprionate.
estradiol cyclopentyl propionate
a pharmaceutical preparation used in dogs; recorded as a cause of hyperestrogenism.
