Pediatric Absence of Vagina or Inadequate Vaginal Length
Certain congenital (present at birth) conditions in females lead to an absent vagina or a vagina that is not adequate for sexual function, and may not permit menstruation.
It's quite rare for a female to be born with an absent or inadequate vagina — about 1 in every 5,000 to 7,000. Several rare conditions lead to either an absent vagina or a vagina that is not deep enough for sexual function.
Conditions that can lead to an absence of vagina or inadequate vaginal length include:
- Mayer-Rokitansky-Küster-Hauser syndrome – condition in which the vagina did not develop while the female baby was developing in the mother's womb.
- Vaginal agenesis – rare disorder in which the vagina doesn’t develop and the uterus may only partially develop (if at all).
- Vaginal atresia – condition in which the vagina is abnormally closed or absent.
Symptoms of these conditions often go unnoticed until girls reach puberty (between the ages of 10 and 14 for females*.) Symptoms include:
- Teenaged female who hasn't yet menstruated
- Monthly cramping and/or abdominal pain without having a period
