Developmental competence and results of blastocyst transfer from three groups
| Group oocytes | Survived oocytes | Fertilization | Cleavage | 3–4-cell | Blastocyst | Expanded blastocyst | Number of birth/transfer | Birth weight | Placental weight |
|---|---|---|---|---|---|---|---|---|---|
| Fresh 261 | 245 (93.9%)a | 222 (90.6%) | 218 (98.2%)ac | 209 (94.1%)a | 173 (77.9%)ac | 56/108 (51.9%) | 1.27 ± 0.20 | 0.14 ± 0.03 | |

Differences in the fertilization rate, 3–4-cell, blastocyst rates, and expanded blastocysts among the three groups were significant (p < 0.05). Values with different superscripts within a column are significantly different (p < 0.05)
