2. Figure 1
Concentrations of (A) stromal cell-derived factor-1 (SDF-1), (B) vascular endothelial growth factor (VEGF), and (C) protein in follicular fluid (FF) in individual follicles with follicular diameter. Numbers in parentheses indicate the number of individual follicles. Results are the mean ± SEM. Statistically significant differences are indicated by brackets: *P<.05; and **P<.01.

3. Figure 2
Concentrations of (A) stromal cell-derived factor-1 (SDF-1), (B) vascular endothelial growth factor (VEGF), and (C) protein in follicular fluid (FF) in individual follicles with follicular volume. Numbers in parentheses indicate the number of individual follicles. Results are the mean ± SEM. Statistically significant differences are indicated by brackets: *P<.05; and **P<.01.

4. Figure 3
The correlation between concentrations of stromal cell-derived factor-1 (SDF-1) and vascular endothelial growth factor (VEGF) in follicular fluid (FF). A total of 352 FF obtained from follicles with a diameter ≤20 mm were analyzed. There is a positive correlation between SDF-1 and VEGF in FF (r = 0.407, P<.01).

5. Figure 4
Concentrations of (A) stromal cell-derived factor-1 (SDF-1) and (B) vascular endothelial growth factor (VEGF) in follicular fluid (FF) in individual follicles with oocyte recovery. A total of 352 follicles with a diameter ≤20 mm were analyzed. Numbers in parentheses indicate the number of individual follicles. Statistically significant differences are indicated by brackets: *P<.01.
