Interspecific pregnancy (literally pregnancy between species, also called interspecies pregnancy or xenopregnancy) is the pregnancy involving an embryo or fetus belonging to another species than the carrier. Strictly, it excludes the situation where the fetus is a hybrid of the carrier and another species, thereby excluding the possibility that the carrier is the biological mother of the offspring. Strictly, interspecific pregnancy is also distinguished from endoparasitism, where parasite offspring grow inside the organism of another species, not necessarily in the womb.
It has no known natural occurrence, but can be achieved artificially by transfer of embryos of one species into the womb of the female of another.
