rome and Infertility--Female

The aim of this prospective observational study is to determine the different outcomes of IVF/ICSI treatments after using antagonists or agonists of gonadotrophin-releasing hormone (GnRH) for controlled ovarian hyperstimulation (COH) in normal responder patients. Two hundred forty-seven patients undergoing IVF treatment at the Centre of Reproductive Medicine, Rome (CERMER), from January 2005 to December 2008, were included in the study. Patients were stimulated either with a standard long protocol with GnRH agonists (n = 156) or with GnRH antagonists (n = 91). The use of GnRH antagonists resulted in a significant reduction in the duration of the stimulation (Agonist Group 14.10 ± 2.25 vs Antagonist Group 11.34 ± 2.11; p < 0.001) and in the amount of gonadotrophin (IU of r-FSH) needed (Agonist Group 1878 ± 1109 vs Antagonist Group 1331 ± 1049; p = 0.0014). Moreover a lower number of cycles were cancelled with the antagonist protocol (4.39 vs 6.41%). The GnRH antagonist protocol, when compared to the GnRH agonist one, is associated with a similar clinical pregnancy rate, similar implantation rate, significantly lower gonadotrophin requirement and shorter duration of stimulation. For this reason, GnRH antagonists might be a good treatment even for normal responder patients undergoing IVF.
