Abstract: Objective (s): assessment of embryo grades on day five/six? And the potential of slow developing embryos Design: prospective analysis of single embryo transfer (SET). Setting: private IVF center Giza, Egypt. Subject: women who had fresh (SET) on day five/six. From January 2016 to December 2017. Age 20 – 35 years old were included. Embryo scoring was done using Gardner grading system, besides, 5 grades were added. Only non-compacting embryos were excluded. Intervention(s): chromosomal analysis of each grade may add more prediction. Result(s): Analysis of cycles (n=326) revealed positive clinical pregnancy (42.3%). Analysis of difference resulted single embryo with expansion or hatching (EH) stages or 1, 5, or 6 were significantly associated with higher clinical pregnancy rates. Conclusion: EH and TE are significantly correlated with clinical pregnancy, however, no specific grade should be excluded except for arrested embryos, as no golden grade. Prediction of pregnancy might be calculated according to our findings.
