Following passage through the oviduct, the coelomic envelope of Discoglossus pictus (amphibia) acquires fertilizability upon reorganization, conversion of gp 42 to gp 40, extensive glycosylation, and formation of a specific layer

This paper describes the morphological and biochemical changes in Discoglossus pictus coelomic oocyte envelope (CE) following passage through the oviduct. As in other anurans, in this species, the transformation of the envelope into vitelline envelope (VE) leads to the acquisition of fertilizability...
