Embryo aneuploidy and ivf outcomes in patients with different spermatozoa aneuploidy rates

Abstract

Our goal was to study the 13, 18, 21, X, Y chromosomes aneuploidy rate in the embryos of the couples with different spermatozoa aneuploidy rate.In prospective cohort study 56 infertile couples were divided into 3 groups by the spermatozoa aneuploidy rate and preimplantation genetic diagnosis (PGD) by fluorescence in situ hybridization performance.There was a statistically significant correlation between the spermatozoa aneuploidy rate and the number of aneuploid embryos (r=0,19; p=0,0248). The most common types of chromosomal aberrations were 21 and X chromosome monosomy, and sex chromosomes polysomy. In the PGD group with spermatozoa aneuploidy level >0,7% the pregnancy rate was 50% as compared with no-PGD group with pregnancy rate of 8,6% (Kaplan–Meier; p=0,0135).Patients with high rate of spermatozoa aneuploidy are at risk of chromosomal aberrations in the embryos.
