Top 4 Intersex Conditions (simplified)

https://en.wikipedia.org/wiki/Intersex#Population_figures

Late onset congenital adrenal hyperplasia: complicated. Gals with beards or chest hair
Hypospadias: Guys who don't pee out their dick
XXY: Guys with small balls
XXX: Gals who are tall

Article is hard to understand. I can't even find ambiguous genitals in the list.
So the movie is not about XXY. Which condition is it?
