title: Fertility preservation by ovarian stimulation and oocyte cryopreservation in a 14-year-old adolescent with Turner syndrome mosaicism and impending premature ovarian failure.
abstract: OBJECTIVE
  To report a novel approach to fertility preservation in adolescents with Turner syndrome mosaicism by repeated controlled ovarian stimulation and oocyte cryopreservation.
  
  
  METHODS
  Case report.
  
  
  METHODS
  Academic reproductive medicine center.
  
  
  METHODS
  Fourteen-year-old adolescent diagnosed with Turner syndrome mosaicism.
  
  
  METHODS
  Two cyles of controlled ovarian stimulation and oocyte cryopreservation within 1 year.
  
  
  METHODS
  Recovery of oocytes after controlled ovarian stimulation and oocyte cryopreservation.
  
  
  RESULTS
  Eleven oocytes were retrieved, of which eight were mature and three were immature during the first cycle. One year later, four mature and three immature oocytes were retrieved after a treatment cycle with even higher gonadotropin doses. All oocytes were cryopreserved by vitrification.
  
  
  CONCLUSIONS
  Controlled ovarian stimulation and oocyte cryopreservation may be an option for fertility preservation in selected adolescents with Turner syndrome mosaicism and impending ovarian failure.
