Estetrol is synthesized in the fetal liver from estradiol ( E2 ) and estriol ( E3 ) by the two enzymes 15?-and 16?-hydroxylase.

Estrone is the least abundant of the three hormones; estradiol is present almost always in the reproductive female body, and estriol is abundant primarily during pregnancy.

GPER binds estradiol though not other endogenous estrogens, such as estrone or estriol, nor for other endogenous steroids, including progesterone, testosterone, and cortisol.

The positional isomer of estriol 16?-glucuronide, estriol 3-glucuronide, also occurs as an endogenous metabolite of estriol, although to a much lower extent in comparison.
