You know this how?

If you are genetically resistant to androgen, you don't need surgery to combat its effects. If you are not phenotypically male, you won't need surgery either.

factually incorrect. there are documented cases of children born with male genetailia who proved Testosterone resistant when they reached puberty. There are a couple of cases of spontaneous cross-gender puberty in middle age. There is a condition which I can't spell call Klienfelder Syndrome or some such which has to do with androgen sensitivity.

All these are cases where the male genetalia would already be present from birth. which would require surgical intervention.

and that's without getting into the complexity of the effects of androgen in utero.
