es·tro·gen

also oes·tro·gen  (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.

es·tro·gen

(ĕs′trə-jən)
Any of a group of steroid hormones that primarily regulate the growth, development, and function of the female reproductive system. The main sources of estrogen in the body are the ovaries and the placenta. Estrogens are also formed by certain plants.

estrogen

1. A collective name for female sex hormones made in the ovaries, which produce female secondary sexual characteristics and stimulate growth of the lining of the uterus.
2. Any of several sex hormones responsible for female sex characteristics; produced in the ovaries and, to lesser degree, in the testicles.

There is extensive evidence to support the concept that WHR is an accurate indicator of androgenicity (male hormone effect), estrogenicity (female hormone effect) (Evans, Barth, & Burke, 1988), risk of major diseases (Bjorntorp, 1991), and potential reproductive success (De Ridder et al.
