hahaha then no, i reckon if person got pregnant whilst in either animal morph, or as a male in female morph - the babies wouldn't survive since in both cases the babies would not be able to exist or be supported by the body. the baby would be gone after the person demorph, and if it didn't, the animal bay would be incompatible with a humans body anyway - just like how an animal sperm cannot get a human pregnant and vice verse. the baby animal would just perish. and with a human male who gets pregnant while in female morph, once he demorphs if the didn't hadn't already been eliminated by the morphing process, then it obviously would not survive in the male body as males are not equipped with the neccesary organs required to sustain a baby like a females body i.e. ovary, wombs and whatever.
but maybe im wrong (its got me thinking of that arnold schwartzanegger movie where he gets pregnant lol xD)
