From one of the article's sources on "1.7%": > Specifically, Fausto-Sterling computes the incidence of intersexual births to be 1.7 per 100 live births, or 1.7%. To arrive at that figure, she defines as intersex any “individual who deviates from the Platonic ideal of physical dimorphism at the chromosomal, genital, gonadal, or hormonal levels” So someone with elevated estrogen but normally functioning male genitalia and XY chromosomes would be part of this 1.7%, as might an effeminate looking man or a boyish female. I rather suspect that is not what most people would assume when reading that number.
