A cautionary note against embryo aneuploidy risk assessment using time-lapse imaging

Area of Science:

• Reproductive Medicine
• Genetics
• Embryology

Background:

• Preimplantation genetic screening (PGS) for embryo aneuploidy is crucial for in vitro fertilization (IVF).
• Current PGS involves embryo biopsy, prompting a search for non-invasive methods.
• Non-invasive PGS could revolutionize IVF by enabling universal use and improving outcomes.

Purpose of the Study:

• To evaluate claims that time-lapse imaging algorithms can perform non-invasive PGS for embryo aneuploidy.
• To assess the scientific basis for using time-lapse imaging to predict aneuploidy and improve IVF outcomes.

Main Methods:

• Review of existing publications on time-lapse imaging for PGS.
• Analysis of current data regarding the efficacy of time-lapse imaging algorithms.
• Comparison of claimed advancements with published evidence.

Main Results:

• Recent claims of increased pregnancy rates via time-lapse imaging for aneuploidy detection are unsubstantiated.
• Published data does not support the premature conclusions presented in recent articles.
• Existing evidence suggests these claims are misleading.

Conclusions:

• The use of time-lapse imaging for non-invasive PGS is premature.
• Further rigorous investigation, including larger age-adjusted datasets or randomized controlled trials, is necessary.
• Current evidence does not support the routine use of time-lapse imaging for aneuploidy screening in IVF.
