A vaginal septum
is a congentital partition within the vagina
; such a septum could be either longitudinal or transverse.
Longitudinal septum - double vagina
A longitudinal vaginal septum develops during embryogenesis
when there is an incomplete fusion of the lower parts of the two mullerian ducts
. As a result there is a double vagina
. There may be associated duplications of the more cranial parts of the mullerian derivatives, a double cervix
, and either a uterine septum
or uterus didelphys
The person with a longitudinal vaginal septum may be asymptomatic and not aware of the condition. If dyspareunia is a problem a simple resection of the septum could be performed.
A transverse septum can form during embryogenesis when the mullerian ducts fuse improperly to the urogenital sinus
. A complete transverse will block menstrual flow and is a cause of primary amenorrhea
. The accumulation of menstrual debris behind the septum is termed cryptomenorrhea
. Some transverse septa are incomplete and may lead to dysparunia or obstruction in labor
. A surgical incision will relieve the situation.
