1 in 4500 newborn girls will be born with “normal female external genitalia and [have] normal breast and pubic hair development”, but will find out as a teenager that their vagina and uterus are underdeveloped or absent. This often means that the women cannot get pregnant and may need surgery before they can have sex. Link: Mayer-Rokitansky-Küster-Hauser syndrome: MedlinePlus Genetics
I don’t think external genitalia (either “normal” or a lack thereof at early stages) should be used to indicate anything about the body as a whole.
