title: Hormonal, genetic and clinical findings in an XX male.
abstract: A 17-year-old XX male with constitutional delay of growth and development and genetic short stature is described. Testosterone levels were normal but luteinizing-hormone-releasing-hormone-stimulated gonadotropin concentrations were increased. Testicular biopsy showed atrophic tubuli seminiferi and hyperplasia of the Leydig cells, and the spermiogram indicated azoospermia. Molecular analysis demonstrated the SRY gene close to the centromere of the paternally derived X chromosome. Clinical data in addition to the cytogenetic and molecular aspects are discussed.
