Time-lapse in the IVF-lab: how should we assess potential benefit?

Area of Science:

• Reproductive Medicine
• Embryology
• In Vitro Fertilization (IVF)

Background:

• Time-lapse imaging (TLI) is increasingly used in fertility laboratories globally.
• The technology aims to enhance embryo selection for improved in vitro fertilization (IVF) success rates.

Purpose of the Study:

• To critically evaluate the evidence supporting the benefits of TLI in IVF.
• To analyze methodological limitations in current TLI research.
• To propose optimal study designs for assessing TLI features and discuss future research directions.

Main Methods:

• This is an opinion paper, involving a critical review and analysis of existing literature and research methodologies.
• Discussion focuses on the ethical implications of adopting new technologies in assisted reproduction.

Main Results:

• Current evidence supporting the benefit of TLI for improving live birth rates is limited.
• Existing studies often suffer from methodological flaws, questioning the reliability of their findings.
• The cost-effectiveness and safety of TLI require further high-level evidence.

Conclusions:

• The widespread adoption of TLI in IVF may be premature due to insufficient high-quality evidence.
• Ethical considerations regarding the implementation of expensive technologies without proven benefits are paramount.
• Further rigorous research is needed to establish the true value of TLI in improving IVF outcomes and patient safety.
