Abstract
Purpose To compare aneuploidy rates in first trimester pregnancy losses following IVF ± ICSI. Methods A retrospective cohort analysis of karyotypes of abortuses following conventional IVF (n = 159) and ICSI (n = 196). Results 50.1% of losses were found to be cytogenetically abnormal among all patients undergoing IVF ± ICSI. A significant increase in fetal aneuploidy rate was noted with increasing maternal age (39 years. = 65.9%). Aneuploidy rates were similar in the ICSI vs. conventional IVF groups (52.6% vs. 47.2% [p 0.31, RR 1.11, 95% CI 0.90, 1.38]). More sex chromosome anomalies were noted in the ICSI group. Conclusions The aneuploidy rate in first trimester abortuses significantly increases with increasing maternal age. ICSI was not shown to significantly increase the aneuploidy rate. However, more sex chromosome anomalies were found among pregnancies resulting from ICSI.This publication has 27 references indexed in Scilit:
