Chromosomal anomalies were found in 7 out of 37 couples experiencing habitual abortion. This suggests a genetic link in recurrent pregnancy loss, impacting reproductive health outcomes.

Area of Science:

  • Reproductive Medicine
  • Genetics
  • Obstetrics

Background:

  • Habitual abortion, defined as three or more consecutive pregnancy losses, affects a significant number of couples.
  • Identifying underlying causes is crucial for effective management and improving live birth rates.
  • Chromosomal abnormalities are a known, but not fully quantified, factor in recurrent pregnancy loss.

Purpose of the Study:

  • To investigate the prevalence of chromosomal anomalies in couples presenting with habitual abortion.
  • To assess the potential contribution of genetic factors to recurrent pregnancy loss in the studied cohort.

Main Methods:

  • Retrospective analysis of 37 couples diagnosed with habitual abortion over a two-year period.
  • Karyotyping or other relevant cytogenetic analyses were performed on couples exhibiting habitual abortion.

Main Results:

  • Out of 37 couples with habitual abortion, seven (18.9%) exhibited chromosomal anomalies.
  • The identified anomalies varied among the affected couples, indicating diverse genetic underpinnings.

Conclusions:

  • Chromosomal anomalies represent a notable etiological factor in habitual abortion.
  • Genetic evaluation should be considered in the diagnostic workup for couples with recurrent pregnancy loss to guide reproductive counseling and treatment strategies.
