2,127. Human-Looking and Non-Human-Looking
Hilchos Issurei Biah 10:8
Let’s say that a woman miscarries something that resembles an animal or a bird. If the face looks human, it is considered a birth even though the rest of the body appears non-human. If it’s male, she observes the laws that apply following the birth of a boy; if female, the laws that follow the birth of a girl. If the gender can’t be identified, she must observe the laws that apply following the birth of a boy and a girl. If the face doesn’t appear human, it isn’t considered a fetus and the mother isn’t rendered unclean from birth impurity. This is so even if the rest of the body appears human, with human hands and feet, and is male or female.
Hilchos Issurei Biah 10:9
A human-looking face means that the forehead, eyebrows, eyes, cheeks and the shape of the jaw look like those of a human being. Expelling such a fetus is considered a birth even if the mouth, ears and nose resemble those of an animal.
