Not that it's all too relevant, but this is simply not true. A person's biological sex is determined at conception by the presence or absence of the y chromosome. Males were never female in the womb.
That's an extremely narrow view of biolgical sex. Genes may or may not get expressed throughout a lifetime or are expressed at certain times. This is why babies do not grow beards for example. There is also a stochastic mapping from genotype to phenotype. The Y chromosone also isn't devoted to sexual differences and encodes many other things as well.
It's like saying that no matter how badly you follow the recipe for souffle, you will always end up with a souffle, even if what you end up with is indistinguishable from a loaf of bread.
