Estrogen is the primary female sex hormone. Among other roles, it promotes the development and maintenance of female characteristics in the human body. Estrogen is a generic term for estrus-producing compounds; the three most common naturally occurring estrogens are: Estrone (E1), estradiol (E2), and estriol (E3).
Symptoms of low estrogen typically occur in women approaching and experiencing menopause. However, younger women can also experience low estrogen, but their symptoms (and causes) differ from menopausal women. There are three types of estrogen: estriol, estradiol and estrone.
