I was thinking this as well, especially if there are no children around. Since Viera live for 300+ years, it could be that the Viera around right now are those who survived the Flood. The males died fighting or are so rare now that they're hidden away to the point not even Viera females will even hint at them being around/alive just in case they're killed off - thus resulting in their race going 'byebye'. In any case... unless the Viera can breed some other way, the Vii race might be heading towards extinction. Which is a lot different compared to the Viera on the source as we know the males are still there.
Might be a cool plot if it turns out that jumping from the first and the source can be done with ease - so Viera males from the source can move to the first to stop such an 'extinction' crisis - if the males are all dead and the Vii need males for cute little tiny buns.
