fetuses
Developing womb occupants
Fetuses is the plural of fetus—an unborn mammal after major structures have formed, typically from eight weeks after conception until birth in humans.
The word appears frequently in medical and political contexts: The ultrasound showed healthy fetuses, laws restricting abortion of viable fetuses.
Also spelled foetuses in British English.
