a generic term for any of the estrus-producing compounds (female sex hormones), including estradiol, estriol, and estrone. Called also estrogenic hormone. In humans, the estrogens are formed in the ovary, adrenal cortex, testis, and fetoplacental unit, and are responsible for female secondary sex characteristic development, and during the menstrual cycle, act on the female genitalia to produce an environment suitable for fertilization, implantation, and nutrition of the early embryo. Uses for estrogens include oral contraceptives, hormone replacement therapy, advanced prostate or postmenopausal breast carcinoma treatment, and osteoporosis prophylaxis.
conjugated e's a mixture of the sodium salts of the sulfate esters of estrone and equilin; therapeutic uses are similar to those of other estrogens; administered orally, intravenously, intramuscularly, or intravaginally.
esterified e's a mixture of esters of estrogenic substances, principally estrone, having therapeutic uses similar to those of other estrogens.


Generic term for any substance, natural or synthetic, that exerts biologic effects characteristic of estrogenic hormones such as 17β-estradiol. Estrogens are formed by the ovary, placenta, testes, and possibly the adrenal cortex, as well as by certain plants; they stimulate secondary sexual characteristics, and exert systemic effects, such as growth and maturation of long bones, and are used therapeutically in any disorder attributable to estrogen deficiency or amenable to estrogen therapy, such as menstrual disorders and menopausal problems. They control the course of the menstrual cycle.
