That sounds more plausible, and would also explain how you can play as an Argonian with the Shadow birthsign without any limitations in the games. My first thought was that maybe Argonian parents would avoid conception 9 months before Second Seed (or however Argonian pregnancies work.) which would mean there may be a smaller pool of children to train.
