Vascular endothelial growth factor and inhibin A in follicular fluid of infertile patients who underwent in vitro fertilization with a gonadotropin-releasing hormone antagonist

We demonstrated that GnRH antagonist administration in infertile patients undergoing IVF did not alter the follicular fluid content of VEGF and inhibin A, and, probably, maturation and quality of oocytes as well. These results demonstrated the usefulness and safety of this drug on controlled ovarian stimulation (COS) protocols.
