I'm pretty sure that they had already tried using the sperm from the banks only to have the male children die from the MKVirus.
The thing to remember is that they are trying to produce MEN that are immune to said virus.
And consideeing the state the world was in possibly a few weeks...

From what I have read through this entire mange there doesn't really seem to be any push in the science department besides the MC finding a cure fornthe MK Virus and that would be a pretty interesting thing to bring up later on in the manga.
The latest chapter just asked possibly the most frequently thought question and I fucking love it.
This is a very good tie with Nagatoro considering they both have had complete 180s in their stories somewhat.
In the end I am hoping for the best out of this manga.
