Ovoviviparous are beings in which fertilized eggs develop within the female
(unlike oviparous), and the embryo gains no nutritional substances from the
female (unlike viviparous).  It occurs in some invertebrates, fishes, and
reptiles.

Humans, like nearly all mammals, are viviparous because the baby receives
nutrition from the mother.
