Medical term:

estrenes


estrogen

 [es´tro-jen]
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.

es·tro·gen

(es'trō-jen),
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.
Synonym(s): estrin, oestrogen

estrogen

also

oestrogen

(ĕs′trə-jən)
n.
1. Any of several steroid hormones, such as estradiol and estrone, that are produced primarily by the ovaries, stimulate the development and maintenance of female secondary sex characteristics, exert systemic effects such as the growth and maturation of long bones, and promote estrus in many female mammals. Estrogens synthesized from plant sources or obtained from horses are used as drugs, primarily to treat estrogen deficiency.
2. Any of several synthetic compounds that mimic the physiologic activity of estrogen, such as ethinyl estradiol, used primarily in oral contraceptives.

Estrogen

Female hormone produced by the ovaries and released by the follicles as they mature. Responsible for female sexual characteristics, estrogen stimulates and triggers a response from at least 300 tissues, and may help some types of breast cancer to grow. After menopause, the production of the hormone gradually stops.
