Table 1. Hatching and degeneration rate in bovine blastocysts cultured with and without MWNTs (0.2 μg ml−1).
Exposure period | N | Group | Hatching (%) | Degeneration (%) |
---|---|---|---|---|
24 h | 68 | Control | 89.71 | 8.82 |
71 | MWNT | 83.10 | 5.63 | |
48 h | 68 | Control | 91.18 | 13.24 |
71 | MWNT | 87.32 | 14.08 | |
72 h | 68 | Control | 92.65 | 14.71 |
71 | MWNT | 87.32 | 15.49 |
There were no differences among groups (Chi-square, p > 0.05).
N = number of embryos.
