Background & Objectives: Infertility (abortion & stillbirth) is one of the most common medical problems during pregnancy. Approximately 10-15% of all clinically recognized pregnancies are lost before the birth. Pregnancy loss is a multifactorial phenomenon. This study was an attempt to analysis the cytogenetic abnormalities of the parents with frequent spontaneous abortion and stillbirth.
Methods: In this study, the samples were analyzed by GTG-banding technique.
Results: From a total of 200 reviewed blood samples, 188 persons (94%) had natural karyotype and 12 persons (6%) had chromosomal abnormalities. Chromosomal aberrations were found in 5 (2.5%) females and 7 (3.5%) males. The prevalence of chromosomal abnormalities was as follows: 5(41.6%) pericentric inversion of chromosome 9, 3 (25%) polymorphism 15p+, 1(8.3%) translocation, 1 (8.3%) polymorphism 15ps+, 1 (8.3%) polymorphism 1qh+ and 1 (8.3%) unknown chromophil band on the short arm of chromosome 21.
Conclusion: Chromosomal analysis is an important etiological investigation in couples with recurrent spontaneous abortions and stillbirth, and genetic counseling helps to make a correct decision on further options of reproduction. |
