Relationship between the volume of follicular fluid that was aspirated from individual follicles and the rates of oocyte retrieval and maturity
| Variable | Volume of follicular fluid that was aspirated from an individual follicle (mL) | P‐value | |||||
|---|---|---|---|---|---|---|---|
| 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) | ||
| No. of aspirated follicles | 128 | 154 | 170 | 123 | 100 | 76 | – |
| No. of retrieved oocytes | 69 (53.9)** | 97 (63.0) | 117 (68.8) | 90 (73.2) | 78 (78.0)* | 55 (72.4) | .001 |
| MII oocytes | 48 (69.6)* | 77 (79.4) | 102 (87.2) | 78 (86.7) | 62 (79.5) | 48 (87.3) | .028 |
| Immature oocytes | 16 (23.2)** | 14 (14.4)* | 6 (5.1) | 4 (4.4) | 4 (5.1) | 2 (3.6) | <.001 |
| Degenerated oocytes | 5 (7.2) | 6 (6.2) | 9 (7.7) | 8 (8.9) | 12 (15.4) | 5 (9.1) | .372 |
Values are presented as N (%). The number of retrieved oocytes and metaphase II, immature (MII and germinal vesicle), and degenerated oocytes were evaluated by using the chi‐square test and residual analysis. A P‐value of <.05 was considered to be statistically significant.
*P < .05 and **P < .01.
