XXY

I will not get into any comments on the movie despite the medical facts. I think other people can do and have done this better than me. I just want to say I loved this movie and for who is interested here are some facts why the story is fictional:

Alex seems to have both genders. She seems to have both - a vagina and a penis - and the doctors already noticed that before she was born. That is referred to as real hermaphroditism, but it is actually not a part of Klinefelter's syndrome, which is a so-called "pseudo-hermaphroditism". All children with an extra X chromosome in addition to XY (so 47,XXY-children) are BOYS. The Sex-determing Region of Y is making them develop to boys. So they won't have nor a vagina nor a uterus and until puberty they are usually not even diagnosed.

Boys with Klinefelter's Syndrome usually consult a doctor because of insufficient growth of the testes in puberty. Some get gynecomastia (breast development in boys) and stay with a high voice. The penis and hair usually develop normal.

So as long as they don't have a genetic abnormality on their Y-chromosome they won't be real hermaphrodites, which is a really rare condition anyway and comes along with the normal Karyotypes 46,XX or 46,XY in most cases.

Anyway it is a great movie! Enjoy!
