Rupture of fetal membranes

Last revised by Arlene Campos on 19 Jan 2024

A rupture of membranes (ROM) or amniorrhexis is a term used during pregnancy to describe a rupture of the amniotic sac. This can occur as part of normal birth (or "spontaneously")  if it occurs at full term at the onset of, or during, labor. It is also  colloquially known as "breaking water."
