Use of Corifollitropin Alfa for Ovarian Stimulation: A Retrospective Analysis of 804 Women Undergoing IVF/ICSI

Background: Corifollitropin alfa in GnRH antagonist protocol could provide a friendly treatment for IVF patients. There is limited evidence regarding the outcomes of corifollitropin alfa in ovarian hyperstimulation in Asian population. Methods: This was a retrospective study conducted on IVF women from July 2012 to July 2018. The recruited patients were expected normal responders, expected poor responders and oocyte donors. The patients underwent GnRH antagonist protocol with corifollitropin alfa. Results: There were 804 IVF patients included in the study. The patients were analyzed into: normal ovarian reserve-autologous cycles ( ≤ 36 years and ≤ 60 kg, n = 33; ≤ 36 years and > 60 kg, n = 9; > 36 years and ≥ 50 kg, n = 204; > 36 years and < 50 kg, n = 52), normal ovarian reserve-donor cycles ( ≤ 60 kg, n = 234; > 60 kg, n = 104) and diminished ovarian reserve cycles (n = 168). In each group of patients, the pregnancy outcomes of fresh embryo transfer were comparable to those of frozen embryo transfer. Conclusions: Corifollitropin alfa could offer an effective and simple treatment option for all groups of patients without PCOS.
