The depopulationists will still not be happy with this. The fact is that nature makes females more hardy than males in crisis situations. So only a few healthy males are needed to impregnate the females for life to go on... and when life gets tough, the births are skewed towards making more females.
Not sure I could agree. It just so happens that certain chemicals affect either the process of deciding which eggs turn out female and any that are destined to be male seem to abort. It may indeed be true that becoming a male may be a delicate thing.
Post birth the two chemicals named in the movie seem to be implicated (in any other things I have read) in encouraging females to mature more rapidly.
This has been shown to be true in animals as well as humans.
For some guys in the future the idea of having a large harem of women to choose from may not be just a pipe dream.
Ayurveda describes the process of gender selection and what can be done to influence the process. A Vaidya friend of mine is familiar with the process and he has 2 boys. Gender selection does not occur for awhile after conception.
I once knew an aboriginal (inuit) woman who said she knew the method for influencing gender selection and practiced it. She wanted boys only and that's what she had. Two boys. I meant to ask her how she did it but as I did not know her very well, I was too shy to ask.
