Background: The purpose of this study was to evaluate the gender ratio and incidence of chromosomal anomalies in the products of conception (POC) from recurrent miscarriages.
Methods: We determined the karyotypes of POC from patients with recurrent spontaneous miscarriages between 1999 and 2009.
Results: In total, 313 specimens were successfully karyotyped, with a median gestational age of 10 weeks at miscarriage (interquartile range 8–13); 199 (64%) were females and 114 (36%) were males. In total, 121 (39%) had abnormal karyotypes, the most prevalent of which were chromosome 21 and 16 trisomies, triploidy, and monosomy X.
Conclusion: Our findings suggest that female POC might be more susceptible to recurrent miscarriages than male ones during embryogenesis, implantation, and initial fetal development.
