Brief summary
This prospective study with sibling oocytes will evaluate the efficiency of two commercial single-step media, namely Sage 1-step and Continuous Single Culture Medium (CSCM), in terms of embryo utilization rates, blastocyst formation rates, embryo quality and pregnancy rates. Embryos will be cultured continuously for up to 6 days under identical conditions.
Interventions
Half of each patient's oocytes will be randomly allocated to be cultured either in Sage 1-step medium (Origio) or in CSC medium (Irvine Scientific) for up to six days following oocyte retrieval.
