EXCEPT:

1. You can be born appearing female, but have a 5-alpha reductase deficiency and grow a penis at age 12. Medically, this condition is known as “5-alpha reductase deficiency.

2. You can be born legally male with an X and a Y chromosome, but your body is insensitive to androgens, and you appear female. Androgen insensitivity syndrome is a condition that affects sexual development before birth and during puberty.

3. You can be born legally male with an X and a Y chromosome, and have a penis and testes, *and* a uterus and fallopian tubes. This another form of androgen insensitivity syndrome.

4. You can be born legally male with an X and a Y chromosome, but your Y chromosome is missing the SRY gene, which gives you a female body. This is a condition known as Swyer syndrome.

5. You can be born legally female with two X chromosomes, but one of the Xs has an SRY gene, which gives you a male body. This another form of Swyer syndrome.

6. You can be born legally female with two X chromosomes - and also a Y chromosome, which gives you a male body. This child would be "intersex", another form of Swyer syndrome.

7. You can be born legally female with two X chromosomes, but your adrenal gland doesn't produce enough cortisol, and your body develops as a male. This is a condition known as X-linked adrenal hypoplasia congenita and affects the development of the adrenal glands.
