Vaginal rugae are structures of the vagina that are transverse ridges formed out of the supporting tissues and vaginal epithelium in females. Some conditions can cause the disappearance of vaginal rugae and are usually associated with childbirth and prolapse of pelvic structures. The rugae contribute to the resiliency and elasticity of the vagina and its ability to distend and return to its (nearly) previous state. These structures not only allow expansions and an increase in surface area of the vaginal epithelium, they provide the space necessary for the vaginal microbiota. The shape and structure of the rugae are supported maintained by the lamina propria of the vagina and the anterior and posterior rugae.
