Clinical Trial Summary

This is a prospective, randomized, single center, phase 4 controlled trial. The study will compare the efficacy of two different strategies for the management of predicted poor response patients under stimulation for IVF/ICSI: up to three MNC cycles (group 1) versus a single GnRH antagonist CFA (group 2).
