title: Development of severe ovarian hyperstimulation syndrome after inadvertent stimulation with a gonadotropin-releasing hormone agonist and human menopausal gonadotropin in a pre-existing early pregnancy.
abstract: OBJECTIVE
  To report a case of severe ovarian hyperstimulation syndrome (OHSS) after inadvertent GnRH long protocol/hMG stimulation in a pre-existing early pregnancy.
  
  
  METHODS
  Case report.
  
  
  METHODS
  Private infertility clinic.
  
  
  METHODS
  A 28-year-old woman who conceived spontaneously following IVF and cryo-embryo transfer (cryo-ET).
  
  
  METHODS
  IVF/intracytoplasmic sperm injection (ICSI), cryo-ET, analgesia, and forced diuresis.
  
  
  METHODS
  Viable pregnancy.
  
  
  RESULTS
  Viable pregnancy with OHSS despite inadvertent administration of GnRH-agonist, stimulation with hMG, and ET in a pre-existing pregnancy.
  
  
  CONCLUSIONS
  Observation of follicle development following stimulation during pregnancy with low quantity and poor quality oocytes combined with abnormal endometrium.
