I think this is an issue that the Church doesn’t have a complete understanding over. I saw a documentary made maybe a decade ago (before they were calling them intersexed), and the documentary stated that the chromosomes of false hermaphrodites are XY (false hermaphrodites have both secondary organs. True have both primary organs and typically aren’t aware of their condition until they deal with infertility). Now, it’s easier to remove an organ than to add one, so typically these XY children have had their male organs removed and have been raised as girls.
Since watching this documentary, I have heard that it is more complicated than the children being XY. There’s a lot of condemnation for mutilating the children’s sexual organs which I would agree with.
The Church tends to prefer to simplify the issue by putting an emphasis on the ability to engage in cloitus. And without surgury, typically these individual have an underdeveloped organs. One might dominate over the other. People are rarely directly in the middle and if they are, they often aren’t capable of cloitus.
