Abstract

Objective: Compare the conception rate in in vitro fertilization cycles using frozen versus fresh embryo transfer.
Study Design: A retrospective cross-section observational study.
Objective: Compare the conception rate in in vitro fertilization cycles using frozen versus fresh embryo transfer.
Materials and Methods: The study was conducted using records from Ganna IVF centers between January 2015 and June 2022 for patients who underwent their first cycle of frozen embryo transfer (FET) after a freeze-all cycle and those who underwent their first cycle of fresh ET. ovarian stimulation was done using the flexible antagonist protocol. Artificial hormone replacement cycles were used for FET, and high-quality cleavage stage embryos were used during embryo transfer. The measured outcome for this study was the clinical pregnancy.
Results: There was significant difference in the rate clinical pregnancy 50.2% (621/2777) in the FET group and 46.9% (2156/2777) in the fresh ET group.
Conclusion: Frozen embryo transfer strategy shows superior results regarding the clinical pregnancy rate when compared to fresh embryo transfer in the selected patients of this study.
