The Effect of Dual Trigger (GnRH Agonist + hCG) for Final Maturation in Oocyte Donors With History of a Previous Cycle With Suboptimal Response to GnRH Agonist Only Trigger

The goal of this clinical trial is to compare GnRH-agonist trigger with dual GnRH-agonist and HCG trigger in oocyte donors. The main questions it aims to answer are: * Maturation rate (Metaphase II/ Total number of COCs collected) * Fertilization rate * Embryo quality day 3 * Fragmentation rate embryo day 3 * Blastulation rate (Day5/6/7) * Quality of blastocyst (Gardner criteria) Participants will undergo controlled ovarian stimulation with a GnRH antagonist protocol Researchers will compare the effects of final maturation with GnRH-agonist trigger to a dual trigger (hCG and GnRH-a)
