4. FIGURE 3
Serum (top panel) and follicular fluid (bottom panel) concentrations of E2 (□), interleukin (IL)-1β (○), IL-6 (□), and vascular endothelial growth factor (VEGF, •) relative to basal values. EFP = early follicular phase; MFP = midfollicular phase; LFP = late follicular phase; ELP = early luteal phase.
