All five of these authors used the colloquial term "hermaphrodite" as the foundation of their taxonomies, although Simpson himself questioned the propriety of the word in his publication. Use of the word "hermaphrodite" in the medical literature has persisted to this day, although its propriety is still in question. An alternative system of nomenclature has been recently suggested, but the subject of exactly which word or words should be used in its place still one of much debate. Pseudohermaphroditism
"Pseudohermaphroditism" has, until very recently, been the term used in the medical literature to describe the condition of an individual whose gonads and karyotype do not match the external genitalia in the gender binary sense. For example, 46,XY individuals who have a female phenotype, but also have testes instead of ovaries—a group that includes all individuals with CAIS, as well as some individuals with PAIS—are classified as having "male pseudohermaphroditism", while individuals with both an ovary and a testis (or at least one ovotestis) are classified as having "true hermaphroditism". Use of the word in the medical literature antedates the discovery of the chromosome,  thus its definition has not always taken karyotype into account when determining an individuals sex.
