Our Western (European, North American) culture continues to make great strides towards extinction. :)) With a 1.2-1.6 birthrate (replacement rate is 2.1), the average Westerner, if lucky, by his/her (my apologies for the insensitive personal pronouns) late twenties will potentially decide his/her gender. At the same time in other cultures, by the same age people have raised a family. 

Life is a funny thing ... at the end it always gets it right. We arrogant Westerners tend to believe that we somehow can control it with our politically correct manipulations ... it is laughable. 

This reminds me of Late Antiquity  Rome when emperors were bringing in laws for strengthening and improving marriage, and increase birthrates, in response to the attempts for politically correct manipulations of life the time ... and we all know, how the Roman Empire ended. :))
