Independent samples t-test and chi-square or Fisher’s exact tests were applied for statistical analysis in quantitative (Age, Number of retrieved oocytes, MІІ oocyte, Fertilized oocyte, 2PN rate and Number of transferred embryos) and qualitative data (High quality embryos, Clinical pregnancy rate, Live birth rate, Multiple pregnancy and Congenital anomaly)
