Primary | fertilization rate | Normal fertilization rate was defined as the presence of two pronuclei (2PN) at the time of fertilization assessment, 16-19 h after ICSI or conventional insemination. The percentage of top quality embryos was defined as the percentage of top quality embryos among the total number of 2PN embryos. Blastocyst forming rate was calculated as number of formed blastocysts devided by number of cultured blastocysts. | the time of fertilization assessment, 16-19 hours after ICSI or conventional insemination |
