Elder demons I think of as being 'created' long ago by some powerful being, an Arch Demon or maybe one of the two Elder Gods we know nothing about. Other demons though, probably concepted via normal means, with possibly the death of either parent at the end. However, I doubt that normal  pregancy is undergone for the birth, and some other device is used for the spawning.
