Non-invasive methods for embryo selection.

Area of Science:

• Reproductive Medicine
• Embryology
• Genetics

Background:

• Assisted reproductive technology (ART) use is increasing globally.
• Optimizing embryo selection is crucial for improving pregnancy rates and reducing multiple gestations.
• Current methods, primarily morphological assessment, have limitations.

Approach:

• This review critically analyzes various non-invasive embryo selection methods.
• Evidence-based evaluation of promising techniques is presented.
• The potential of these methods to supplement or replace morphological assessment is explored.

Key Points:

• Non-invasive embryo assessment methods offer potential advantages over traditional techniques.
• Metabolomic, transcriptomic, and kinematic analyses are among the promising approaches.
• The clinical utility and validation of these methods require further investigation.

Conclusions:

• Non-invasive embryo selection techniques show promise for improving ART outcomes.
• Further research and standardization are needed to integrate these methods into clinical practice.
• These advanced methods may offer a more objective and effective approach to embryo selection.
