Comparison of chromosomal abnormality rates in ICSI for non-male factor and spontaneous conception

Abstract

OBJECTIVE: To compare cytogenetic data of first-trimester missed abortions in intracytoplasmic sperm injection (ICSI) for non-male factor-mediated and spontaneous pregnancies. METHODS: Using karyotype analysis, we conducted a retrospective cohort trial of missed abortions following ICSI for non-male factor and spontaneous pregnancies. Patients experienced missed abortions during the first 12 weeks of pregnancy. Dilation and curettage procedure was performed followed by cytogenetic evaluations. Two patient groups were created: ICSI (n = 71) and spontaneous pregnancies (n = 81). At least 20 GTG-banded metaphases were analyzed in each case for cytogenetic analyses. Statistical analyses were performed using NCSS 2007 Statistical Program software. The significance level and confidence interval for all analyses were set to p < 0.05 and a 95% confidence interval, respectively.
