Septa may be transverse or longitudinal. Transverse vaginal septa are generally located at the junction of the upper third and lower two‐thirds of the vagina. They are probably caused by failure of either the Müllerian duct or urogenital sinus contributions to the vagina to cavitate completely so they can occur at any level. It is inherited as an autosomal recessive trait in the Amish community [56]. Presentation is usually at puberty with retained menstrual products or a continuous vaginal discharge [57].

A longitudinal vaginal septum is not uncommon and lies in the sagittal plane. They are the result of a fusion defect in the Müllerian system and are associated with abnormalities of the uterus and cervix. In one study of 83 women with a longitudinal vaginal septum, only 3 had a normal uterine cavity [58]. These septae may be displaced to one side and difficult to see. Surgical removal is recommended as they can cause major difficulties with vaginal delivery. A double vagina may be found where one side is not patent, and menstrual products collect in one side causing obstruction.
