A septate uterus is a congenital uterine anomaly where a fibrous or muscular septum divides the uterine cavity into two sections. This condition occurs during fetal development and can vary in severity, with some women having a partial septum while others have a complete division. Women with a septate uterus may experience complications such as recurrent miscarriages or difficulties during pregnancy. Diagnosis is typically made through imaging techniques like ultrasound or MRI. Treatment options often include surgical removal of the septum to improve reproductive outcomes.
