The Intersex Society of North America Recommends That "Surgeries Done

The Intersex Society of North America recommends that "surgeries done to make the genitals look 'more normal' should not be performed until a child is mature enough to make an informed decision for herself or himself." Usually,doctors would always try to involve a patient in his or her treatment,so why is this advice necessary?

A) There are serious health risks associated with being born intersex that must always be addressed immediately.
B) So few people are born intersex that no one knows about them.
C) In our society, the prospect of an ambiguously sexed person seems so threatening that surgical procedures are performed long before a child is old enough to know what is happening.
D) Intersex is based on secondary, not primary, sex characteristics, and these won't develop until later in life.
