estrogen
Sign in to saveEstrogen (American English) or oestrogen (Commonwealth English; see spelling differences) 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. Another estrogen called estetrol (E4) is produced only during pregnancy.
AI overview
Estrogen is a category of sex hormone that develops and regulates the female reproductive system and secondary sex characteristics, with estradiol being the most common and potent form in the body. There are several types of estrogen produced naturally, including estrone, estradiol, and estriol, plus a fourth type called estetrol that only appears during pregnancy.

Estrogens are synthesized in all vertebrates and some insects. Quantitatively, estrogens circulate at lower levels than androgens in both men and women. While estrogen levels are significantly lower in males than in females, estrogens nevertheless have important physiological roles in males.
