Study Questions Reliability of Genetic Testing in IVF

10/24/2025

Summary

Story summary

Key Information: University of Cambridge researchers question the reliability of pre-implantation genetic testing for aneuploidy (PGT-A) in IVF.
The study suggests PGT-A may mislabel embryos as abnormal due to placenta-related errors, not embryonic issues.
Embryos were observed for 46 hours, showing that genetic abnormalities can develop between testing and implantation.
Further research is needed to understand implications and improve screening methods to boost IVF success.
