Vaginal agenesis, or absence of the vagina, is a congenital disorder of the female reproductive tract. It affects approximately one in every 5,000 female infants. The cause of vaginal agenesis is unknown.
A woman with complete vaginal agenesis may have this abnormality based on the fact that the vagina did not grow during embryologic development and this is called Mayer-von Rokitansky-Kuster-Hauser's syndrome. There are many variations to this syndrome; a woman may have no vagina and no uterus, (in which case she would however have normal ovaries) alternatively, she may have no vagina and may have a single midline uterus and no cervix. If this is the case she will not have periods that will allow flow of blood out of her body as she has no cervix and no vagina. With menstruation and shedding of the endometrial lining, the blood would go in a retrograde fashion.
Women with a midline uterus and vaginal agenesis have options for correction of this problem which include: suppression of retrograde menses with the utilization of a continuous oral contraceptive pill with preservation of the uterus in the midline so that she could potentially carry a pregnancy with the utilization of assisted reproductive technologies and a planned abdominal delivery (cesarean section).
Alternatively, surgical procedures have been described to create a communication between a vagina which is created and the upper uterus. There have been cases where this has been successful, however, there have been numerous cases where this has resulted in an infection and the need for a hysterectomy, and there have been four reported deaths from this procedure.
Thus, at Children's Hospital Boston it is recommended that a woman with vaginal agenesis with a midline uterus and no cervix go through a procedure for creating a functional vagina for sexual relations and would maintain her uterus with the utilization of continuous oral contraceptive pills to suppress retrograde menses and the risk of endometriosis. She would thus be a candidate for reproductive technologies with the utilization of GIFT for the placement of the eggs and sperm within the fallopian tubes for possible pregnancy. The birth of the child would require a cesarean section.
Women with vaginal agenesis can also have small rudimentary uterine horns which are lateral to the midline. These uteri can also function, if they contain an endometrial stripe women with rudimentary uterine horns can also be managed in a similar fashion to what is described above, for women with a single midline uterus.
