Estradiol is the primary form of estrogen in the body, and it plays a role in the regulation of the female reproductive system. It contributes to the development and maintenance of female reproductive tissues, influences the menstrual cycle, and has effects on various organs and tissues, including the breasts and bones. One of the hallmarks of menopause is a decline in estrogen, which can be addressed by hormone replacement therapy.
