Trans natal males don't have CAIS, though.

how does that change the argument?

Unless I'm understanding that report wrong, he didn't have a functioning ovary, in fact the ovarian tissue was extirped among the cistic mass.

still means ovarian tissue.

I stand by what I said multiple times already female refers to the biological category of individuals whose bodies are built around the potential capability of producing large gametes (ova) at some point in their life. And likewise for males and sperm.

except that you don't define what "built around the potential capability of producing" a particular gamete means.

Not all females can get pregnant, but only females can get pregnant.

maybe. I mean, naturally? Of course yes (since anyone on the female side of the bimodal spectrum close enough to the "typical" case to be fertile would also be close enough to the typical case to be easily sorted in as female under the binary modell). Artifically? Maybe you only need an Uterus and a female hormone profile(though if we discount the Mikey Chanel case [which might or might not be a hoax] it is going to be hard to find volunters to test that, and I don't think any scientific journal is going to accept a paper to the effect of "I abducted some guy who, due to rare genetic abnormality had an uterus, subjected him into a hormone regime against his will, and forcibly impregnated him. Here's my results.")

Hermaphrodites are individuals who can produce either gamete. Sequencial hermaphrodites start producing one kind of gamete and later swich to produc the other one. Simultaneus hermaphrodites can produce both kinds at the same times. We agree (I think) that humans can't swich the kind of gamete one can produce. So, humans are not sequential hermaphrodites.

so far, yes.

There are rare cases where things go wrong and you find a mixture of female and male feaures.

precisely. Some amount of male or female or both or neither.

However, there are no reported case of people both functional set of reproductive systems because we're not supposed to produce both ova and spermatozoa.

No, there aren't reports of both being functional. But there doesn't have to be, since not having a functional one of either doesn't disqualify.
