For so long women have been the ones who have been blamed when a couple can't get pregnant, but this shows that is not always the case. Also, we have been led to believe that males don't have to worry about getting older and breeding later in life because they are seen as eternally virile, this has been shown to be false.
So what does this mean for the future?
As we approach the new Aeon of Veritas this is naturally occurring anyway, but of course, chemicals and pesticides are speeding up the process. But this won't lead to human extinction. It will lead to women gaining back their ability to reproduce asexually, as was the way in the past before the first male was born caused by a mutation on one of the X chromosomes, leading to the development of the shorter mutated Y chromosome.
There will come a time when human population numbers will decline greatly and this is when women will gain this ability back. Humans will not become extinct.
