title: Gestational age of pregnancy loss in women with unexplained recurrent miscarriage.
abstract: OBJECTIVE
  The aim of this study was to investigate the gestational age (GA) of pregnancy loss in women with unexplained recurrent miscarriage (RM) and to determine whether the miscarriages occur at similar GA in RM women.
  
  
  METHODS
  This retrospective study was carried out in a university hospital and included 288 women with unexplained RM. The GA at which each miscarriage occurred was carefully determined. Overall, 739 miscarriages were analyzed.
  
  
  RESULTS
  RM women had miscarriages at a median GA of 7 weeks (range: 3-20). In RM women, 47.2% (n = 136) experienced miscarriages within a 1-week range of GA and 53.4% (n = 154) had miscarriages in the same period of fetal development (pre-embryonic, embryonic or fetal).
  
  
  CONCLUSIONS
  Women with unexplained RM tend to have miscarriages at the same GA, which is characteristic for each patient.
