Preimplantation genetic screening: "established" and ready for prime time?

Area of Science:

• Reproductive Medicine
• Genetics
• Embryology

Background:

• Preimplantation genetic screening (PGS) aims to improve pregnancy and reduce miscarriage rates.
• Current applications of PGS lack clearly defined patient indications.
• The efficacy of PGS is debated without specific selection criteria.

Discussion:

• The effectiveness of PGS is contingent upon careful patient selection.
• Undefined indications limit the widespread successful application of PGS.
• Treating PGS as experimental acknowledges current limitations in its application.

Key Insights:

• Patient selection is critical for the success of preimplantation genetic screening.
• The lack of defined indications makes PGS an experimental approach.
• Further research is needed to establish clear guidelines for PGS use.

Outlook:

• Future research should focus on identifying specific patient subgroups who benefit from PGS.
• Establishing clear indications will be crucial for transitioning PGS from experimental to standard practice.
• Optimizing PGS protocols requires a better understanding of its role in various patient populations.
