Antagonist/Letrozole in Poor Responders
NCT00823004 · Status: COMPLETED · Phase: PHASE1/PHASE2 · Type: INTERVENTIONAL · Enrollment: 120
Last updated 2013-12-23
Summary
Failure to respond to controlled ovarian hyperstimulation (COH) is still a major concern in assisted reproduction and there is no consensus on the ovarian stimulation choice regime for poor responders.
Aim: To evaluate and compare the efficacy of a microdose GnRH agonist flare (MF) and a GnRH antagonist/letrozole (A/L) protocols in poor responders undergoing in vitro fertilization (IVF).
Methods: One hundred eighty poor responder patients will be randomized to an ovarian stimulation protocol with either a MF or a letrozole and high dose FSH/hMG and flexible GnRH antagonist protocol.
