You can't be an XX male since 2 Xs make you female and XY makes you male. Maybe you are talking about the people who are XXX, X, or XXY? Either way with those genetic abnormalities you are still consider male or female.
I guess people complain so much about gender that a genetic testing is the only way to shut them up. Remember that runner who won and people would't let it go until there was some testing done?
I just wonder is she lied about it and they found out or if they knew all along and when there was too much controversy they just drop her lie a hot potato.
XX males exist. They arise by a translocation of the SRY gene located on the Y chromosome to the X chromosome. However, they are sterile of course and present abnormalities.
