title: A potential new use for gonadotropin-releasing hormone antagonists.
abstract: OBJECTIVE
  To describe a potential new use of gonadotropin-releasing hormone (GnRH) antagonists.
  
  
  METHODS
  Case report.
  
  
  METHODS
  Assisted conception unit at a teaching hospital in the United Kingdom.
  
  
  METHODS
  A 37-year-old woman undergoing in vitro fertilization (IVF) who accidentally stopped using GnRH agonists after starting ovarian stimulation.
  
  
  METHODS
  A GnRH antagonist was used to avoid a luteinizing hormone (LH) surge and hence "rescue" the cycle.
  
  
  RESULTS
  Successful oocyte retrieval was carried out, two embryos transferred, and a viable twin pregnancy ensued.
  
  
  CONCLUSIONS
  This may be a new indication for the use of GnRH antagonists.
