Woops !
The 1.7% number you are quoting has been debunked. This is according to the
US National Library of Medicine National Institutes of Health
Here's what they concluded:
Abstract
Anne Fausto-Sterling s suggestion that the prevalence of intersex might be as high as 1.7% has attracted wide attention in both the scholarly press and the popular media. Many reviewers are not aware that this figure includes conditions which most clinicians do not recognize as intersex, such as Klinefelter syndrome, Turner syndrome, and late-onset adrenal hyperplasia. If the term intersex is to retain any meaning, the term should be restricted to those conditions in which chromosomal sex is inconsistent with phenotypic sex, or in which the phenotype is not classifiable as either male or female. Applying this more precise definition,
the true prevalence of intersex is seen to be about 0.018%, almost 100 times lower than Fausto-Sterling s estimate of 1.7%.

You should have considered the source and whether or not they have an agenda or axe to grind. Sort of like the media polls before the 2016 election.
I will take the work of the National Institute of Health, I doubt they have an axe to grind one way or the other.
I will say again, you either have XX chromosomes or XY chromosomes and only 0.018% are born as both male and female.
