Evaluation of day one embryo quality and IVF outcome ? a comparison of two scoring systems
Original language description
Background: The aim of our retrospective study was to compare the clinical usefulness of two non-invasive embryo scoring systems based either on a simplified pronuclear morphology of the zygote or on early cleavage rate, as well as their combination, forthe selection of embryos with the best implantation potential in embryo transfer (ET). Methods: Over a period of five years, the quality of 2708 embryos from 364 IVF cycles in women under the age of 39 years was assessed using these scoring systems in auniversity assisted reproduction centre. ET was always performed on day 3 of cultivation. The outcome of ETs of 702 embryos scored in the respective systems or their combination was retrospectively analyzed in terms of biochemical (bPR) and clinical pregnancy rates (cPR) and implantation rate (IR). Mann?Whitney U test and t-test for differences between relative values were used, p < 0.05 was considered statistically significant. Results: There was no difference in outcome parameters in
