My common sense tells me yes. I doubt it has ever come up at an official level, as this condition hasn’t been well-known for that long. Before the advent of DNA testing and other advanced medical procedures and knowledge (ultrasound, etc.), they would have just been assumed to be women who were sterile, and for some reason never started having menstrual periods. Some of these women I’ve seen online have been very striking-looking and not in the least bit masculine.This said, though, if an intersex person cannot consummate in a normal manner, sadly, they could not marry in the Church.
I seriously have to doubt that the Church would ever take the position of “DNA determines gender regardless of any appearances to the contrary”. The Church has enough problems without going to the cross over something that was never even known to be an issue until recent times. I would say that “male and female He created them” would allow appearance, anatomy and self-perception to trump DNA. As someone else noted above, AIS women have never been influenced by androgen (because their system is insensitive to it), so chances are they have never “felt” anything other than female. I once heard a woman on a TV show, a very nice-looking young woman, say “I don’t have periods”, and I wonder if she was AIS.
