Table 2 Effect of exposure of embryos at 116 h after insemination to 40°C for 8 h on percent of inseminated oocytes that cleaved and that developed to the blastocyst stage and on blastocyst cell number [inner cell mass (ICM), trophectoderm (TE) and total]
Treatment | Number of oocytes (replicates) | Percent cleaved | Percent developed to blastocyst | ICM cell number | TE cell number | Total |
|---|---|---|---|---|---|---|
Control | 293 (5) | 74.0 ± 3.5 | 30.4 ± 1.1 | 28.3 ± 1.4 | 75.2 ± 4.1 | 103.5 ± 5.0 |
Heat shock | 320 (5) | 74.5 ± 5.3 | 28.8 ± 5.3 | 28.1 ± 1.1 | 79.3 ± 3.9 | 107.4 ± 4.5 |
