Abstract

Purpose: The aim of this study was to analyze parental decisions regarding pregnancies in which the fetus had sex chromosome abnormalities (SCA) over a ten-year period. Materials and Methods: We collected and reviewed records from our hospital for 2001-2010 and a genetic specialist provided-genetic counseling. Results: We diagnosed 130 cases (0.71%) with SCA out of 18,376 prenatal cases from 2001 to 2010. We reviewed the records and the results of all pregnancies. We also included cases (n=84) of apparently normal anatomic fetuses to analyze the factors influencing parental decisions. We excluded 34 cases with an obvious anomaly or a presumably bad outcome and 12 cases that were not followed up. Forty-three couples (51.2%) continued their pregnancies while forty-one (48.8%) terminated them. Of 38 mosaicism cases, 21 (55.3%) were continued. Among the 20 pregnancies assisted by reproductive techniques, 15 (75%) were continued (P=0.02). More pregnancies were continued when genetic counseling was provided (61.9%) compared to cases in which it was not provided (19%) (P=0.01). Conclusion: Genetic counseling is important in providing appropriate information to parents. Establishing guidelines and protocols will help both obstetricians and parents to make informed decisions.
