Uterine Septum

Definition - What does Uterine Septum mean?

A uterine septum is an abnormality of the uterus that causes the uterine cavity to be divided by a membrane called a septum. The septum may split the uterus completely or partially. While a uterine septum will not prevent pregnancy from occurring, it may lead to implantation issues and other complications that put the pregnancy and delivery at high risk. However, if diagnosed before pregnancy occurs, it possible to treat a uterine septum through surgery.

FertilitySmarts explains Uterine Septum

A uterine septum is a congenital condition, which means it originated during development as a fetus. In early embryonic development, a female fetus has two uteri (plural of uterus), one located by each kidney. As development progresses, both uteri travel down towards the tissue that will become the vagina, and towards the center of the body where they fuse together. The wall created by this fusion is normally completely reabsorbed. In the case of a uterine septum, the uteri fuse together and the wall is only partially reabsorbed.

If diagnosed before pregnancy, a uterine septum can be treated. A minimally invasive procedure called a hysteroscopy can be used to access the uterus and remove the septum.

A pregnant woman with an undiagnosed or untreated uterine septum faces a heightened chance of miscarriage, recurrent miscarriage, pre-term labor, or laboring in the breech position.
