In some affected women, the septum is partial or does not extend the length or width of the vagina.

A longitudinal vaginal septum develops during embryogenesis when there is an incomplete fusion of the lower parts of the two Müllerian ducts.

[1][2] A transverse septum forms during embryogenesis when the Müllerian ducts do not fuse to the urogenital sinus.

Some transverse septa are incomplete and may lead to dyspareunia or obstruction in labour.
