But if born-male pregnancy was something that could be easily flipped on, our selfish genes would be using it to salvage their position when they find their male survival-machine out-competed. People would evolve to always be born "male", but spontaneously "transmaxx" themselves if celibate too long, even if the mind is revolted by the idea and the celibacy was a deliberate effort to avoid responsibility for kids.
