Güevedoces (roughly translated as "penis at twelve") is a term used in the Dominican Republic for children with a specific type of intersexuality. Güevedoces are classified as girls when they are born but, around the age of 12, they start developing male genitalia. This is due to a deficiency in the production of 5α-reductase, an enzyme involved in the metabolism of testosterone to dihydrotestosterone.[1][2][3][4][5] The same phenomenon occurs in Papua New Guinea, where it is called kwolu-aatmwol by the Sambia people ('which suggests a person's transformation "into a male thing."'),[6] and in Turkey.[7] Anne Fausto-Sterling states that güevedoces (as well as people in Papua New Guinea with 5α-reductase deficiency) "are recognised as a third sex" by their cultures, while the cultures "nevertheless recognize only two gender roles."[6]
