a hormone that activates andrigen and oestrogen ?
Answers
Explanation:
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. Another estrogen called estetrol (E4) is produced only during pregnancy.

Estrogens are synthesized in all vertebrates[1] and some insects.[2] Their presence in both vertebrates and insects suggests that estrogenic sex hormones have an ancient evolutionary history. Quantitatively, estrogens circulate at lower levels than androgens in both men and women.[3] While estrogen levels are significantly lower in males compared to females, estrogens nevertheless have important physiological roles in males.[4]
Like all steroid hormones, estrogens readily diffuse across the cell membrane. Once inside the cell, they bind to and activate estrogen receptors (ERs) which in turn modulate the expression of many genes.[5] Additionally, estrogens bind to and activate rapid-signaling membrane estrogen receptors (mERs),[6][7] such as GPER (GPR30).[8]
In addition to their role as natural hormones, estrogens are used as medications, for instance in menopausal hormone therapy, hormonal birth control and transgender hormone therapy for transgender women and nonbinary people.
