Sorry for the long post.. I usually hate this but it seems that intersex people still only are xx and xy -
46, XX intersex
This condition used to be called "female pseudohermaphroditism". Persons with this condition have female internal genitalia and karyotype (XX) and various degree of external genitalia virilization.[194] External genitalia is masculinized congenitally when female fetus is exposed to excess androgenic environment.[188] Hence, the chromosome of the person is of a woman, the ovaries of a woman, but external genitals that appear like a male. The labia fuse, and the clitoris enlarges to appear like a p**is. The causes of this can be male hormones taken during pregnancy, congenital adrenal hyperplasia, male-hormone-producing tumors in the mother and aromatase deficiency.[188]
46, XY intersex
This condition used to be called "male pseudohermaphroditism". This is defined as incomplete masculinization of the external genitalia.[195] Thus, the person has the chromosomes of a man, but the external genitals are incompletely formed, ambiguous, or clearly female.[188][196] This condition is also called 46, XY with undervirilization.[188] 46, XY intersex has many possible causes, which can be problems with the testes and testosterone formation.[188] Also, there can be problems with using testosterone. Some people lack the enzyme needed to convert testosterone to dihydrotestosterone, which is a cause of 5-alpha-reductase deficiency.[188] Androgen insensitivity syndrome is the most common cause of 46, XY intersex.[188]
True gonadal intersex
This condition used to be called "true hermaphroditism". This is defined as having asymmetrical gonads with ovarian and testicular differentiation on either sides separately or combined as ovotestis.[197] In most cases, the cause of this condition is unknown.
Complex or undetermined intersex
This is the condition of having any chromosome configurations rather than 46, XX or 46, XY intersex. This condition does not result in an imbalance between internal and external genitalia. However, there may be problems with sex hormone levels, overall sexual development, and altered numbers of sex chromosomes.[188]
