In pregnant women, premature rupture of membranes (PROM) occurs when the amniotic sac that surrounds the baby (the membrane) breaks before the start of labor.

When the amniotic folds fuse, the two membranes are formed, with the amnion next to the embryo and the chorion next to the shell. The space between the embryo and the amnion is called the amniotic ...
