According to fausto-sterling, what has been the historical "standard of treatment" for people who have intersex bodies?

The right answer is Forcing the person to conform to either a male gender identity and gender role. Anne Fausto Sterling is a biologist and has conducted several research on the genre. She has proposed a model for people who are born intersex (without a defined sex); they must adopt a definitive gender and assume the role of a culturally accepted gender for the adopted gender, this in order to establish a healthy sexual identity.

I hope my answer can help you.
