Definition / general
  • Also called Swyer syndrome
  • Female phenotype and female genital appearance, normal Müllerian structures
  • Bilateral streak gonads, so no hormonal or reproductive potential
  • 46 XY but no testicular tissue; no evidence of Turner syndrome
  • Early bilateral gonadectomy is recommended due to high incidence of gonadoblastoma and dysgerminoma (J Pediatr Urol 2011;7:72)
