Abstract
Background: An abnormal karyotype in either partner, especially featuring a translocation and/or inversion is considered to be a cause of recurrent miscarriages. It is generally assumed that recurrent miscarriage might be due to recurrent chromosomal abnormalities in the fetus due to a balanced aberration in one of the parents being inherited by the offspring in an unbalanced form. Aim: Evaluation of chromosomal rearrangements in couples with recurrent miscarriages. Materials and Methods: Peripheral blood was collected and lymphocyte cultures were set up. Slides prepared from the cell suspension were stained and screened for metaphases followed by karyotyping. Result: Balanced translocation was observed in the male partner in one case and in the female partners in the three other cases. Conclusion: Couples with recurrent miscarriage should be investigated for chromosomal rearrangements, thus helping in genetic counseling and providing the options for future pregnancies.
