Here we have a rare sighting of a genuine "Follow the science" article in the wild. This species is currently endangered by invasive species and over hunting, so treasure this moment while you can.
Don't think so. Here's a "real" XY female described in an NCBI article from "The Journal of Clinical Endocrinology and Metabolism":
NCBI: "Report of Fertility in a Woman with a Predominantly 46,XY Karyotype in a Family with Multiple Disorders of Sexual Development. .... A 46,XY mother who developed as a normal woman underwent spontaneous puberty, reached menarche, menstruated regularly, experienced two unassisted pregnancies, and gave birth to a 46,XY daughter with complete gonadal dysgenesis.":
Are you and the IOC going to deny her a right to play in women's sports? After she's given birth to two or three children of her own?
It is NOT the karyotypes -- the XX & XY -- that determine membership in the sex categories -- it's the presence of functional gonads, i.e., ovaries -- as above for females -- or testicles for males.
You might actually try reading what are the standard biological definitions for sexes which are generally available in reputable dictionaries like the Oxford English Dictionary which is what Google uses:
From the first link above, the Journal of Molecular Human Reproduction:
"Female: Biologically, the female sex is defined as the adult phenotype that produces the larger gametes in anisogamous systems.
Male: Biologically, the male sex is defined as the adult phenotype that produces the smaller gametes in anisogamous systems."
Khelif and company -- most of the intersex -- are, in fact, neither male nor female because they don't have functional gonads of either of two types, because they can't produce either sperm or ova.
"The condition can result in ambiguous genitals that appear more female, and the babies are often misidentified as girls at birth." In other words, perfect development = male, all others are female. Ambiguous genitalia is not an ID feature for being a female. Male and female differences in development do not begin and end with puberty and we don't fully understand all of the differences that begin at fertilization. While I sympathize with those that have a genetic and/or medical condition, this is very simple; a chromosome test. There was a related dispute, imo, with South African runner Oscar Pistorius, using prosthetic legs, running against abled athletes. In my opinion, he should never have been allowed to run against the athletes that had to run on flesh and bone legs.

Unique perspective on a hateful display of violence towards women that the IOC has ratcheted up the fiery furnace sevenfold. Thanks for the insight.
XY is all the Olympic committee needs to know... but won't.

OED: "male, adjective: Of or denoting the sex that produces gametes, especially spermatozoa, with which a female may be fertilized or inseminated to produce offspring."; https://web.archive.org/web/20190608135422/https://en.oxforddictionaries.com/definition/male
OED: "female, adjective: Of or denoting the sex that can bear offspring or produce eggs, distinguished biologically by the production of gametes (ova) which can be fertilized by male gametes"; https://web.archive.org/web/20181020204521/https:/en.oxforddictionaries.com/definition/female
