NT Is weird,and there is obvious issues with it; which is why we get characters like the cowgirl on Tarvos, who ran away from the treatment before she was old enough to have to take it. Because leaving before it's your time to take it is a known thing.
Anyways as for the male dominated society; how is it any different from the way earth was not 200 years ago? Is it ass-backwards from how it is now, yup. But I feel like it was kinda the point to be that way.
There is 1 male for every 10 females.
