Amniotic fluid production begins early in development, typically around the 4th to 5th week of gestation, initially produced by the amniotic membrane.

The syncytiotrophoblast cells of the placenta are responsible for the production of Human Chorionic Gonadotropin (HCG) to maintain the corpus luteum during early pregnancy.
