Definition:
A uterine septum is a band of tissue in the middle of the uterus, usually without much of a blood supply, that results from a congenital problem in the formation of the woman's uterus. The external surface of the uterus is normal in these cases. Uterine septum is the most common congenital uterine malformation (mullerian duct anomaly).
Having a uterine septum (or septate uterus) is a risk factor for recurrent miscarriages.
