Usually ovarian cysts can’t cause any direct damage to a fetus. Ovarian cysts can affect a pregnancy only if they become complicated by infarction or rupture. Rupture or infarction of a big ovarian cyst causes an acute abdomen that can provoke premature delivery. Delivery of a special needs child can be due to fetal malformations. Fetal malformation are either inborn (genetically conditioned) or acquired during the embryonic development. Ovarian cysts can damage neither the fetus’s genes nor its embryonic development.
