Table 4.
Relationship between time from ICSI to ROA and time from ROA to second polar body extrusion in ROA oocytes that exhibited second polar body extrusion
| Time from ROA to second polar body extrusion (h) | ||||||
|---|---|---|---|---|---|---|
| <0.5 | <1 | <2 | <3 | ≥3 | ||
| Time from ICSI to ROA (h) | <3 | 2 (15.3%) | 2 (30.8%) | 6 (76.9%) | 3 (100%) | |
| 3 to <4 | 5 (3.2%) | 17 (14.1%) | 94 (74.4%) | 30 (93.6%) | 10 (100%) | |
| 4 to <5 | 5 (4.1%) | 13 (14.9%) | 70 (72.7%) | 24 (92.6. %) | 9 (100%) | |
| ≥5 | 1 (5.0%) | 1 (10.0%) | 15 (85.0%) | 2 (95.0%) | 1 (100%) | |
Actual numbers refer to the number of oocytes, % values refer to cumulative second polar body extrusion rates by time from ICSI to ROA; r = 0.071, P = 0.21
