PPOS vs GnRH Antagonist in Ovarian Stimulation (ProGanOS Study)

Summary

This non-inferiority randomized controlled trial will be conducted at My Duc Hospital, Ho Chi Minh City, Vietnam. This study compares the effectiveness of Progestin-Primed Ovarian stimulation versus GnRH protocol for ovarian stimulation in IVF treatment. Participants will be randomly assigned in a 1:1 ratio to receive Progestins or GnRH antagonists.
