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.
