The fact of the matter is, even then, and also now, women are still more important reproductively than men. In this world, it is not quite as necessary due to the immense numbers of the human species, but nevertheless, women are still the more important half.

For instance, if humanity were to undergo— say— a transformation of the short-term solutions sort. It would be sensible for 1-10% of the global population to remain male. For behavioral studies, and for reproductive purposes – a good example to remember is that it would require only one man to populate a city, while it would require an entire city of women for the same task. Women are more important because they bear the child, and thusly, they are needed in greater numbers.

If my short-term solutions were implemented, and men and boys were castrated in great numbers, it would make sense for some men to be able to be signed up through governmentally operated programs to become “Breeders” who would be exempted from castration until they were too old to continue producing viable sperm.

They would be used for sample collection based on supply-and-demand. This, along with the use of scientifically generated progeny, would be able to sustain a perfect population. Primarily female, and sufficiently - to the extent that it is necessary for sample collection - male.

Likewise, mothers or close female guardians would be advised to exempt their male children from castration if it were necessary on the basis of supply-and-demand. They could still go through with it, but they would be advised to not do so until the male grew older.

This practice of castration, Breeder usage, and sample collection would continue until it was scientifically possible to create female children entirely from the organic material of female adults. Then, the existence of men would no longer be necessary at all. Long-term solution implementation would follow.
