Well, this sounds like a very interesting story. Someone should take up the challenge.
I did read a fic where Clark was tortured, but it had something to do with 'them' not wanting him to procreate with humans. I believe Lois and Clark were already married. Sorry, I have no idea what the name of it is.
There was another story where Clark came to Lois as Superman, and he was hurt. They ended up having sex and Lois got pregnant, but poor Superman didn't remember it, and Clark was mad at the guy that got her pregnant. That one I can probably come up with the name.
