Güevedoces is a term used for children with a specific type of intersexuality in the Dominican Republic. They 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.[1][2][3][4][5]

Early research[edit]

The first scientific investigations of the güevedoces occurred in the 1970s, when Dr. Julianne Imperato-McGinley, an endocrinologist from Cornell University traveled to the village of Salinas (population 4300) in the Dominican Republic to investigate reports of apparently female children becoming male children at the onset of puberty.[6] The cause was determined to be 5α-reductase deficiency, and the results were published in the journal Science in 1974. The frequency of the deficiency was found to be unusually high in Salinas, with occurrence ratio of 1 guevedoce to every 90 normal males.[7]
