Wait there is more, just when you thought you'd seen it all

I actually approve of this. Sure, it's disturbing, but off all the creatures in the glaxy, the Reapers would be the last to care about modesty, so there would be no justification for taking the extra energy to give their minions barbie-doll anatomics. With Edi it was simply unecessary, here it seems sorta natural.
Besides, it's not like the game shoves it into our faces, I don't think most players looked at the banshees and were like: "Okay, let's check out her naughty bits"

As opposed to "Kill it, kill it, kill it, KILL IT!!!"
Though I have to admit, this opens up some completely new fridge horror. Think about it. Only ardat yakshi are banshees, and the ardat yakshi are an extremely rare occurence in the asari race. Coupled with the destruction of the monastry via shepard, there should be only a handful of them left, yet multiplayer shows that the reapers have no shortage of them.
Now as said before, the fat and lined stomach makes it look that they are pregnant. Seeing how asari reproduce by simply getting some genetic information from their respective partner to upload on their own dna, which apparently has not been proven to biologically affect the child in any way, it wouldn't be that big of a strech to assume that banshees, thanks to reaper tech, are able to impregnate themselves without a partner (or forcefully extracting genetic information from their victims heads).
Which basically would mean that the reason why there are so many banshees is that they are constantly reproducing, so everytime shepard fights a banshee s/he is either killing a person turned into a monster AND forcefully selfimpregnated
OR
s/he fights like four weeks old, already pregnant monsters.
