  abstract = {Objective: To compare the effect of the multiple-dose GnRH antagonist protocol with the microdose GnRH agonist flare-up (MF) protocol in poor ovarian responders for ICSI. Design: Retrospective, Clinical study. Setting:IVF center. Patient(s): Two hundred eighty-six poor responder patients undergoing ICSI-embryo transfer cycle. Intervention(s): one hundred Forty four patients (144 cycles) included in group 1 (microdose GnRH-a flare-up protocol) and one hundred fourty two patients (42 cycles) included in group 2 (multiple dose GnRH antagonist protocol). Main Outcome Measure(s): Serum E2 levels, number of growing follicles and mature oocytes, embryo quality, dose of gonadotropin used, cancellation, fertilization, implantation rate, pregnancy rate (PR) and live birth rate (LR). Results: Total gonadotropin dose used was significantly lower (2730235,45 vs 3189317,81; P<0.05), duration of stimulation was significantly longer and E2 level was significantly higher in group 1. The mean number of oocytes retrived, mature oocytes retrived, embryos transferred and the rate of at least one top-quality embryo transferred was similar in the two groups. The implantation rate was significantly higher in the microdose flare-up group than in the multiple-dose antagonist group (18.79% vs 8.28%; P<.001). Clinical pregnancy and live birth rates were similar in the two groups. Conclusion(s): We achieved comparable pregnancy and live birth rates in poor responders with the use of either GnRH antagonist or flare protocol. However, a significantly higher gonadotropin dose used and lower implantation rate in the antagonist group tips the balance in favor of the flare-up protocol.},
