Table 4. In vitro embryo development after IVF of vitrified oocytes matured in the presence or absence of pFF.
| pFF in IVM medium | Total§ | Cleaved (%) | Blastocyst (% total) | No. of cells/blastocyst | ||
| day 5 | day 6 | day 7 | ||||
| + | 340 | 122 (36.0±1.3) | 6 (1.8±0.3) | 12 (3.5±0.3) | 13 (3.8±0.4) | 50.0±2.5 |
| – | 354 | 112 (32.5±3.0) | 5 (1.4±0.1) | 11 (3.1±0.1) | 12 (3.4±0.4) | 44.3±1.5* |
Five replications were performed. Data are presented as means ± SEM.
No significant difference was detected between the treatment groups by student’s t-test.
*P = 0.053.
§
