My issue with this episode is the way the world responds to the problem that it has become sterile. No more children will be born, at least "normal" children. First of all it is through utter carelessness and lack of oversight that the whole thing happened (sort of like we are doing with climate change). Secondly, the governments that are responsible for this now form a kind of gestapo group, waiting for a normal birth that they can then test and figure out their next strategy. This, of course, leaves the mother no more than a cog in their wheel. There is an underground anti-government movement that is seen as a terrorist cell. We don't know what they are up to. This has shades of the book "Children of Men." A young couple becomes pregnant and apparently the wife going to have a normal, healthy baby. Enter the fascists, led by one of the men who was responsible for the problem in the first place. This is an intriguing effort to that point, but for me the conclusion is a bit too pat. See it anyway and just ask yourself what would our civilization be like if there were no more children.
