What is Estrogen?
Estrogens, or oestrogen, are the primary female sex hormones. Natural estrogens (oestrogens) are steroid hormones, while some synthetic ones are non-steroidal.
Estrogens, in women, are produced primarily by the ovaries and in the placenta during pregnancy. Follicle-stimulating hormone (FSH) stimulates the ovaries to produce estrogens; 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 post menopausal women. Fat cells produce estrogen as well.
Estrogen levels vary through the menstrual cycle, with levels highest just before ovulation.
