Estrogen is one of the key sex hormones in the female body that is responsible for the development and regulation of the female reproductive system. Estrogen plays a vital role in the menstrual cycle, pregnancy, childbirth, and even a woman's heart and bone health.
The main types of estrogen present in women are estrone (E1), estradiol (E2), and estriol (E3). Estradiol is the predominant and most potent estrogen during a woman's reproductive years. Estrogen levels begin to rise during puberty and peak during the childbearing years. After menopause, estrogen levels decline sharply.
