Estradiol is a hormone from the estrogen family, which also includes other hormones, such as estron and estriol. Estrone predominates during menopause. All estrogens have an aromatic ring and a phenolic hydroxyl group.

Estradiol is a female sex steroid hormone, that is synthesized in the ovaries n the corpus luteum , specifically in the granulosa cells. During pregnancy, this hormone is also produced by the placenta and its plasma value in the body rises. It is the most important female hormone from the first period until menopause. During menopause, a small amount of this hormone is produced by the liver and adrenal glands.
