Abstract
The objective of this study was to investigate the correlation between the concentrations of vascular endothelial cell growth factor (VEGF), nitric oxide (NO), or endothelin-1 (ET-1) in follicular fluid with antral follicle counts (AFCs) or ovarian volume in order to predict the outcome of in vitro fertilization (IVF). One hundred and thirty-one patients were enrolled in this study, and the pregnancy rate was 37.4%. The concentration of VEGF or NO was significantly increased, while the concentration of ET-1 in follicular fluid was decreased in the group who became pregnant (P < 0.05). The ovarian volume or AFC was significantly higher in groups that became pregnant (P < 0.05). In addition, the ovarian volume or AFC was positively correlated with the concentration of VEGF or NO and negatively correlated with the concentration of ET-1 in follicular fluid. Our data suggest that these correlations may be associated with the successful pregnancies through IVF.
