Abstract

Whether the gene expression of vascular endothelial growth factor (VEGF) in human granulosa cells is a predictor of fertilization was evaluated in patients participating in an in vitro fertilization program. Fifty patients with normal ovaries who were participating in an in vitro fertilization program at the University of Milan, San Raffaele Scientific Institute, were included in the study. We correlated E2 and P serum levels on the day of oocyte collection, the number of follicles, oocytes collected, and fertilized, and pregnancies with mRNA for VEGF of luteinizing granulosa cells obtained at the time of oocyte retrieval. Comparing E2 and P serum levels, the number of follicles, oocytes collected and fertilized, and pregnancies with gene expression for VEGF, we found a positive correlation. E2 and P serum levels were higher in patients with increased VEGF (P < 0.01). Furthermore, there were more follicles, oocytes collected and fertilized, and pregnancies in patients with maximum expression of VEGF, and the difference was statistically significant (P < 0.05). Our results suggest that VEGF may be important for vascular development during follicular growth and luteal differentiation, oocyte maturation, and fertilization.
