It goes without saying that humanoids (humans, elves, dwarves, ect.) can't reproduce with demihumans (lizardmen, beastmen, ogres, etc.), but that might not be the case for humanoids and heteromorphs. After all, BDL has "human" descendents and Dark Knight of the 13 Heros is believed to be a half-demon. So I believe [living] hetero's CAN beget offspring with humanoids because of their polymorphic-anatomy.
