Unconjugated Estriol (uE3) is one of the three major estrogens produced by the body, alongside estradiol (E2) and estrone (E1). While it is present in non-pregnant individuals at very low levels, its production increases dramatically during pregnancy. It is unique because its synthesis requires a functional “conveyor belt” of enzymes involving the fetus’s adrenals, the fetus’s liver, and the placenta.
