what structures are responsible for the production of estrogen
Estrogen Estrogens, in females, are produced primarily by the ovaries, and during pregnancy, the placenta.[66] Follicle-stimulating hormone (FSH) stimulates the ovarian production of estrogens by the granulosa cells of the ovarian follicles and corpora lutea. Some estrogens are also produced in smaller amounts by other tissues such as the liver, adrenal glands, and the breasts. These secondary sources of estrogens are especially important in postmenopausal women. Fat cells produce estrogen as well.[67]
Dehydroepiandrosterone Dehydroepiandrosterone (DHEA), also known as androstenolone, is an endogenous steroid hormone.[2][5] It is one of the most abundant circulating steroids in humans,[6] in whom it is produced in the adrenal glands,[7] the gonads, and the brain,[8] where it functions as a metabolic intermediate in the biosynthesis of the androgen and estrogen sex steroids.[5][9] However, DHEA also has a variety of potential biological effects in its own right, binding to an array of nuclear and cell surface receptors,[10] and acting as a neurosteroid and neurotrophin.[11]
