I would argue that Theologians have used the wide idea-space of their mythology to cover a lot of questions some of which also applicable outside of their theology.

I mean, it's not as though religion has a monopoly on that idea. It is mentioned in the article how it has applications in any care-taking role.

Now if you can find someone talking about the possibility of a virgin getting pregnant through her ear or nose, that I will grant you is pretty unique to Christianity in specific time periods when social mores say pregnancy is good, vaginas are bad, and virginity is good..
