Background

Estetrol is an estrogen steroid hormone exclusively produced by fetal liver from estradiol and estriol during pregnancy. It binds to estrogen receptors (ERs) with 4-fold higher affinity for ERα over ERβ and exhibits estrogenic effects in most tissues expressing ERs (bone, brain, vagina, and endometrium).[1],[2] In breast tumors, however, estetrol acts as an estrogen antagonist in the presence of estradiol, preventing tumor growth.[1],[2]
