Birth (calving in livestock and some other animals, whelping in carnivorous mammals) is the act or process of bearing or bringing forth offspring. The offspring is brought forth from the mother. The time of human birth is defined as the time at which the fetus comes out of the mother's womb into the world. Different forms of birth are oviparity, vivipary and ovovivipary.
