Relationship between the volume of follicular fluid that was aspirated from individual follicles and embryonic development
| Variable | Volume of follicular fluid that was aspirated from an individual follicle (mL) | |||||
|---|---|---|---|---|---|---|
| Group A | Group B | Group C | Group D | Group E | Group F | |
| (<1.0) | (1.0‐<2.0) | (2.0‐<3.0) | (3.0‐<4.0) | (4.0‐<5.0) | (≥5.0) | |
| Oocytes with 2 PNs and 2 PBs | 32 | 62 | 83 | 55 | 46 | 40 |
| Cleavage | 31/32 (96.9) | 61/62 (98.4) | 81/83 (97.6) | 55/55 (100.0) | 46/46 (100.0) | 38/40 (95.0) |
| ≥7 cells on day 3 | 17/31 (54.8) | 35/61 (57.4) | 49/81 (60.5) | 40/55 (72.7) | 23/46 (50.0) | 23/38 (60.5) |
| No. of cultured oocytes until day 6 | 20 | 49 | 61 | 38 | 37 | 28 |
| Blastocysts | 8 (40.0)* | 28 (57.1) | 37 (60.7) | 26 (68.4)* | 22 (59.5) | 18 (64.3) |
PB, polar body; PN, pronucleus.
Values are presented as N (%). The rates of cleavage, ≥7 cells on day 3, and blastocyst development were evaluated by using the chi‐square test between group A and each group. A P‐value of <.05 was considered to be statistically significant.
*P < .05: significant difference between group A and group D.
