Studies of the Fetus in the Womb are two coloured annotated sketches by Leonardo da Vinci made in around 1511. [ 1] The studies correctly depict the human fetus in its proper position inside a dissected uterus. [ 2] Leonardo depicted the uterus with one chamber, in contrast to theories that the uterus had multiple chambers which many believed ...
A fetus or foetus ( / ˈfiːtəs /; pl.: fetuses, foetuses, rarely feti or foeti) is the unborn offspring that develops from a mammal embryo. [ 1] Following embryonic development, the fetal stage of development takes place.
Human embryonic development or human embryogenesis is the development and formation of the human embryo. It is characterised by the processes of cell division and cellular differentiation of the embryo that occurs during the early stages of development. In biological terms, the development of the human body entails growth from a one-celled ...
Learning language as an infant also requires fetal memory. It is now known that the mother's voice is clearly heard from inside the womb and that the fetus can differentiate speech sounds, particularly the phonemes (a single segment of sound) in speech. This is evident in the baby when born, showing many signs of early language comprehension.

A lithopedion ( also spelled lithopaedion or lithopædion; from Ancient Greek: λίθος "stone" and Ancient Greek: παιδίον "small child, infant"), or stone baby, is a rare phenomenon which occurs most commonly when a fetus dies during an ...
In human pregnancy, prenatal development is also called antenatal development. The development of the human embryo follows fertilization, and continues as fetal development. By the end of the tenth week of gestational age, the embryo has acquired its basic form and is referred to as a fetus. The next period is that of fetal development where ...
"The baby was anesthetized. The baby was not aware of what was going on." [7] The surgeon who operated on the mother stated that rather than the fetus' hand clutching on to his finger, he was simply pushing the fetus' arm that had suddenly jolted out of the womb back into the womb in order to finish the surgery.

Fetal abductions typically start with the lie that the perpetrator is pregnant and often coincide with a fear of losing a romantic partner. Then the perpetrator murders a pregnant woman to claim the fetus as her own (as a stillborn baby or, if the fetus survives, as a newborn child). [ 8]
