Estrogen

Estrogen is a hormone produced by the follicles used to prepare the uterus for the reception of a fertilised egg. [1]

• estrogen receptors located in the hypothalamus serve as a master switch to control food intake, energy expenditure and body fat distribution [2]
• The woman's ovaries produce most estrogen hormones, although the adrenal glands also produce small amounts of the hormones. [3]
