Semi-automated versus manual embryo vitrification: inter-operator variability, time-saving, and clinical outcomes.

ABSTRACT:

Purpose

Does semi-automated vitrification have lower inter-operator variability and better clinical outcomes than manual vitrification?

Methods

Retrospective analyses of 282 patients whose embryos had been cryopreserved, manually with Irvine®-CBS® (MV) or semi-automatically vitrified with the GAVI® method (AV) (from November 2017 to September 2020). Both techniques were performed during the same period by 5 operators. Inter-operator variability was statistically analyzed between operators who performed the vitrification and those who performed the warming process to compare the intact survival rate (% embryos with 100% intact blastomeres) and the positive survival rate (at least 50% intact blastomeres). Additionally, the complete vitrification time was assessed for the 2 tec
