Entirely reasonable all things considering. If they live longer and presumably have less children, their bodies would likely not continuously cycle through the eggs in preparation to get pregnant. I think it works that way with whales as well, if I remember correctly.

Or elves do have these cycles, but never the pain involved. It's not clear to me what's supposed to be the flaw. The pain or the whole process with the pain?
