Predictive factors for freezing supernumerary embryos: case of the mother-child hospital of Bingerville / Côte d'Ivoire

Abstract

Introduction: Assisted Reproduction Technologies (ART) has enabled many couples to have a child. Freezing is a technique not only to increase the chances of pregnancy but also to reduce the costs of IVF. The aim of this study was to determine the predictive factors for the freezing of supernumerary embryos Methodology and results: This is a retrospective study that involved 85 patients who had undergone an intramarital IVF at the Mother-Child Hospital in Bingerville between September 2019 and August 2021. A univariate analysis made it possible to identify the clinical and biological parameters statistically linked to freezing. Thus, were identified as predictive factors: The value of basal FSH (p=0.04), the total duration of ovarian stimulation (p=0.02), the total number of oocytes obtained (p=0.0001), the number of oocytes in metaphase 2 (p=0.000), the maturation rate (p=0.032), the fertilization rate (p=0.014); The freezing of embryos in a previous cycle has not been determined as a determining factor for freezing in a subsequent IVF.  Conclusion: the determination of a population with a high potential for supernumerary embryos can make it possible to propose appropriate protocols and also to organize the logistics of the centers.
