Cytogenetic analysis revealed chromosomal abnormalities in 7.60% of couples with recurrent miscarriages. These findings highlight the importance of chromosome studies for managing reproductive health.
Area of Science:
- Genetics
- Reproductive Medicine
Background:
- Recurrent miscarriages and poor obstetric history necessitate thorough etiological investigation.
- Cytogenetic studies are crucial for identifying underlying causes in affected couples.
Purpose of the Study:
- To determine the prevalence of chromosomal abnormalities and polymorphic variants in couples experiencing repeated miscarriages.
- To assess the clinical significance of these findings in reproductive health management.
Main Methods:
- A cross-sectional study involving 158 couples with repeated miscarriages.
- Standard cytogenetic analysis of peripheral blood lymphocytes.
Main Results:
- Chromosomal abnormalities were detected in 7.60% of couples, including translocations, inversions, and a novel insertion.
- Mosaicism was observed in 3.80% of couples.
- Polymorphic variants in heterochromatin and Y chromosome were noted in a significant proportion of couples.
Conclusions:
- Chromosome analysis is essential for the appropriate clinical management of couples with recurrent miscarriages.
- Identifying chromosomal abnormalities can guide reproductive counseling and treatment strategies.
