A fetus (or foetus or ftus) is a developing mammal or other viviparous vertebrate, after the embryonic stage and before birth.
The plural is fetuses, or sometimes feti. The fetal stage of prenatal development starts when the major structures have formed, and lasts until birth.[1]
In humans, the fetal stage of prenatal development starts at the beginning of the 11th week in gestational age (the 9th week after fertilization).
