A<unk>  is a vaginal anomaly that is partition within the vagina; such a<unk>  could be either longitudinal or transverse. In some affected women, the<unk>  is partial or does not extend the length or width of the vagina. Pain during intercourse can be a symptom. A longitudinal<unk>  develops during embryogenesis when there is an incomplete fusion of the lower parts of the two Müllerian ducts. As a result, there may appear to be two openings to the vagina. There may be associated duplications of the more cranial parts of the Müllerian derivatives, a double cervix, and either a uterine<unk>  or uterus didelphys (double uterus). A transverse<unk>  forms during embryogenesis when the Müllerian ducts do not fuse to the urogenital sinus. A complete transverse<unk>  can occur across the vagina at different levels. Menstrual flow can be blocked, and is a cause of primary amenorrhea. The accumulation of menstrual debris behind the<unk>  is termed cryptomenorrhea. Some transverse septa are incomplete and may lead to dyspareunia or obstruction in labour.
