A randomized controlled trial published in The Lancet found that time-lapse imaging (TLI) does not improve in-vitro fertilization (IVF) outcomes for individuals undergoing fertility treatment. The study involved over 1,500 participants in the UK and Hong Kong who were randomly assigned to receive TLI-based embryo selection, standard static assessment, or conventional assessment. Live birth rates and clinical pregnancy rates were similar across the three groups, suggesting that TLI does not enhance the chances of successful IVF treatment. The findings indicate that advanced technology like TLI may not always translate into improved clinical outcomes, providing valuable information for stakeholders in the IVF field.
