Estrogen , or oestrogen , is a category of sex hormone responsible for the development and regulation of the female reproductive system and secondary sex characteristics. There are three major endogenous estrogens that have estrogenic hormonal activity: estrone E1 , estradiol E2 , and estriol E3. Estradiol, an estrane , is the most potent and prevalent.
