Thanks for picking this awesome series back up! The official EN release is about to come out and I plan on buying them but I'd love to be able to keep up with the JP release as well.

Men can stay fertile over their entire lifespan, even if the number of healthy sperm decrease with age. It is not unheard of that 70y/o geezers father offspring. The issue here is not being able to create children, it's that the gene pool is too small keep creating healthy children in the long term. The community is too small to restart the human race by itself.
