I never actually understood Kig-Yar reproduction, why would any species need the ability to choose between which gender they want? I'm hoping that Halo:Reach could help reconcile this, perhaps the Skirmishers are male Kig-Yar and so the ability to hold back which is born is because the Skirmishers are so dangerous.

The Sangheili thing you mentioned does sound interesting, LOMI, explains the mandibles, a bit of that is worked into my article. I'm half-considering writing an article on Brute reproduction next, but seeing the massive debate over at my article, I'm a little afraid of doing so.
