^Eh, that's assuming the internal logic is as farfetched as other works. Aside from the man eating humanoids and biological weapons, the science isn't all that out there I think. You're right that it's fiction and it plays by its own rules, though reproduction limitations have been set. Like, unless Itori was lying or her knowledge wasn't accurate, female ghouls can't become pregnant with human males. This next part totally depends on how much real world science Ishida is using, but since Kaneki became a hybrid through organ transplant, his DNA shouldn't be affected and ought to still register as %100 human. Granted, this is using the little knowledge we have about ghoul reproduction and trying to use real world science to figure things out, and if this is the case, there's a low possibility of Kaneki having children with someone all ghoul. Eto's a little more ????? because she's part human.

Take things as you will though, this is all just speculation~
