Abstract

Objectives: The study aims to initially evaluate the results of embryo culture using CSC single-step medium and compare with the results of embryo culture in transition medium. Subject and method: A prospective study was conducted on 66 women having IVF with 806 MII oocytes obtained by ICSI at the IVF Center, Hanoi Medical University Hospital, from August 2020 to August 2021. In which, 479 oocytes after ICSI were cultured continuously until day 5 by CSC single-step medium with day 3-refreshment. The key variables were evaluation of fertilization rate, embryo quality in cleavage stage (day 2), blastocyst quality and some related factors. Result: The fertilization rate, the day 2 embryo rate, the blastocyst rate and the utilization blastocyst rate were 91.66 ± 12.92%; 98.34 ± 5.40; 73.07 ± 13.06%; 69.81 ± 12.96% respectively. Oocytes and sperms quality affects fertilization rate, the utilization of blastocysts rate, statistically significant (p<0,05).
