What is Estriol?
Estriol (also oestriol or E3) is one of the three main estrogens produced by the human body. Estriol is only produced in significant amounts during pregnancy as it is made by the placenta from 16-hydroxydehydroepiandrosterone sulfate (16-OH DHEAS),an androgen steroid made in the fetal liver and adrenal glands.
Levels of estriol in non-pregnant women do not change much after menopause, and levels are not significantly different from levels in men.
