Septae have been strongly linked with an increased risk of adverse pregnancy outcome. One of the most common problems associated with septae is miscarriage. It is thought that this occurs when the embryo attempts to implant on the septum; because the septum does not have a good blood supply, this then compromises the supply of blood to the embryo causing it to miscarry. Other problems associated with the septum are fetal malpresentations during late pregnancy (e.g. breech presentation) and fetal growth restriction.
