74. The whole . . . chromosomes and testostrone determine your sex . . . isn't that simple.

It really, really isn't.

You can have X0, XX, YY, XYY, XXY, XXYY individuals.
Mind you some of those combinations are fatal soon after conception or early in gestation.
And then some genetic combinations of the normal male pattern present as females due to hormone insensitivity.

Some examples:
"Turner Syndrome: This condition affects females who typically have only one X chromosome (45,X). Symptoms include short stature, webbed neck, and incomplete development of secondary sexual characteristics1.

Klinefelter syndrome
Klinefelter Syndrome: Males with this condition have an extra X chromosome (47,XXY). They may have reduced muscle mass, less facial and body hair, and enlarged breast tissue1.

Androgen Insensitivity Syndrome (AIS): Individuals with AIS have a male XY karyotype but are resistant to male hormones (androgens). As a result, they may develop female physical traits despite having male chromosomes.

Congenital adrenal hyperplasia
Congenital Adrenal Hyperplasia (CAH): This condition affects the adrenal glands, leading to an overproduction of androgens. It can cause ambiguous genitalia in females and early puberty in both sexes."

Let's just say:
The young lady boxer isn't someone anyone of us here would like to touch gloves with.
