Structure

The vaginal venous plexus lies around the sides of the vagina.^[1] Its branches communicate with the uterine venous plexuses, vesical venous plexus, and rectal venous plexuses. It is drained by the vaginal veins, one on either side. These eventually drain into the internal iliac veins (hypogastric veins).^[1][2]

Function

The vaginal venous plexus drains blood from the vagina.^[2] It helps to make the vagina highly vascular.^[2]
