Ontogenic changes in the oviductal epithelium parallel changes at subepithelial level.
Collagen remodeling and epithelial budding were spatially and temporally associated.
Cut-off values distinguished between preadenogenic and adenogenic oviducts.
Oviductal epithelial and stromal cells express ER and PR from neonates to juveniles.
High ER in the glandular epithelium showed that adenogenesis is estrogen-dependent.
