Use of Estradiol 

Estradiol is produced especially within the follicles of the female ovaries, but also in other endocrine (i.e., hormone-producing) and non-endocrine tissues (e.g., including fat, liver, adrenal, breast, and neural tissues). Estradiol is biosynthesized from progesterone (arrived at in two steps from cholesterol, via intermediate pregnenolone). One principal pathway then converts progesterone to its 17-hydroxy derivative, 17-Hydroxyprogesterone, and then to * via sequential cytochrome P450-catalyzed oxidations.[citation needed] Action of aromatase on * generates estrone, and action of a dehydrogenase on this gives the title compound, 17β-estradiol.[citation needed] Alternatively, * can be converted into the androgen,  which in turn can be converted directly into 17β-estradiol.
