Advancements and Applications of Preimplantation Genetic Testing in In Vitro Fertilization: A Comprehensive Review

Area of Science:

• Reproductive Medicine
• Genetics
• Assisted Reproductive Technology (ART)

Background:

• Preimplantation genetic testing (PGT) is a key component of assisted reproductive technology (ART).
• It allows for the screening of embryos for genetic abnormalities before in vitro fertilization (IVF) implantation.
• This review examines the advancements and applications of PGT in IVF.

Purpose of the Study:

• To provide a comprehensive review of PGT in IVF.
• To explore PGT's technological developments, clinical applications, and efficacy.
• To discuss challenges, regulatory aspects, and future directions of PGT.

Main Methods:

• Review of advancements in PGT techniques, including next-generation sequencing (NGS) and comparative genomic hybridization (CGH).
• Analysis of the impact of PGT on IVF success rates and genetic disorder incidence.
• Exploration of clinical applications, challenges, and regulatory frameworks.

Main Results:

• PGT techniques like NGS and CGH have significantly improved the accuracy and reliability of embryo genetic testing.
• PGT has profound implications for ART, potentially increasing IVF success rates.
• It can reduce the incidence of genetic disorders and associated burdens.

Conclusions:

• PGT is crucial for the future of ART, offering improved outcomes and reduced risks.
• Recommendations include staying updated on PGT techniques, exploring innovation, and establishing clear regulations.
• Collaboration is essential to maximize PGT's benefits in assisted reproduction.
