In males, relatively small amount of estrogens are produced by Leydig and germ cells of the testis. Additionally, estrogens are synthesized at multiple discrete sites throughout the body from the liver, adrenal glands, and adipocytes,36 where they have highly localized effects on various unrelated ...
Stilbestrol, a synthetic compound with considerable estrogenic activity, has been used extensively in medical practice. See Hormone, Steroid (0) Estrogen any of a number of female sex hormones (including estradiol, estriol, and estrone) produced mainly by the ovarian follicles and placenta and to...
When micewere treated with an estrogen antagonist(a type of medication which prevents estrogen from binding to receptors on cells) they had decreased rates of disease and milder symptoms. One potential explanation for the reason women (females) develop SLE more frequently than men (males) isbecause...
They are produced and secreted directly into the bloodstream by the ovary, testis, adrenal, and placenta of pregnancy. Two other naturally occurring estrogenic hormones, equilin and equilenin, have been obtained only from the urine of pregnant mares and are apparently peculiar to that species. ...

The source of these estrogens is probably the Sertoli cells of the testes (see Chapter 4). The presence of estrogens in males near puberty explains why some pubertal males exhibit slight growth of the mammary glands (gynecomastia). In this condition, a small (1 to 2 cm in diameter) lump...
In males, the interstitial cells produce the male hormones known as androgens. What is the most important androgen? Which of the following options is correct? The major hormone produced by the corpus luteum is a. progesterone. b. estrogen. c. chorionic gona...

Dear Editor, The term estrogen includes thirty hormones, of which the mostknown are estriol, estrone, and estradiol. In females they are produced primarily in the ovaries [1].Besides their well established actions on reproductive functions, estrogens exe
Estradiol is also produced in the ovaries and is the most prevalent form of estrogen. It is responsible for the development of female sex characteristics, and prepares the reproductive cycle for pregnancy. Estriol is the main estrogen in the body during pregnancy, and is made by the placenta. ...
