Randomized Controlled Trial Comparative Study
Corifollitropin alfa compared with follitropin beta in poor responders undergoing ICSI: a randomized controlled trial.
Does substituting 150 µg corifollitropin alfa for 450 IU follitropin beta during the first 7 days of ovarian stimulation in proven poor responders, result in retrieval of a non-inferior number (<1.5 fewer) of cumulus oocyte complexes (COCs)? ⋯ Corifollitropin alfa simplifies IVF treatment because it is administered in a GnRH antagonist protocol and replaces seven daily FSH injections with a single one of a long acting FSH without compromising the outcome. It could greatly reduce the burden of treatment for poor responders and this deserves further investigation.
