FertilitySmarts explains Estradiol (E2)

Artificial estradiol is a main ingredient in many types of hormonal contraceptives, as it can be used to change the balance of hormones governing ovulation, which include estradiol, Gonadotropin-Releasing Hormone, Follicle Stimulating Hormone, and Lutenizing Hormone. Disrupting the balance of these hormones can prevent ovulation from occurring. Estradiol is the form of estrogen which is predominantly produced by women of childbearing age. Most symptoms of menopause are caused by the loss of estradiol as the ovaries stop producing reproductive hormones.
