title: Frequency of abnormal karyotypes among abortuses from women with and without a history of recurrent spontaneous abortion.
abstract: OBJECTIVE
  To compare the frequency of chromosomal abnormalities in products of conception from women with and without a history of recurrent spontaneous abortion.
  
  
  METHODS
  Retrospective analysis of prospectively collected material.
  
  
  METHODS
  Private practice at the Genetics and IVF Institute, Fairfax, Virginia and Grupo de Reproducción AGY Asociados, México City, México.
  
  
  METHODS
  Women with (n = 94) and without (n = 130) a history of recurrent spontaneous abortion who had a spontaneous abortion between January 1, 1992 and November 1, 1994.
  
  
  METHODS
  Chromosomal analysis performed on products of conception using standard G-banding technique.
  
  
  METHODS
  The percentage of chromosomal abnormalities among products of conception from women with and without recurrent spontaneous abortion was compared.
  
  
  RESULTS
  Among products of conception from women with recurrent spontaneous abortion, 57% (54/94) had abnormal and 43% (40/94) had normal chromosome analyses. Products of conception from women without recurrent spontaneous abortion had abnormal chromosome analyses in 57% (74/130) and normal results in 43% (56/130).
  
  
  CONCLUSIONS
  No differences in frequency of abnormal karyotype were observed in products of conception from women with recurrent spontaneous abortion compared with women without recurrent spontaneous abortion.
