New PGT-A test Shows that Nearly All Blastocysts and Fetal Tissue are Mosaic with Meaghan Doyle

Did you know that nearly all embryos show some level of mosaicism, even in successful pregnancies? In this conversation with Meaghan Doyle, a Licensed Certified Genetic Counselor specializing in fertility genetics and the founder of DNAide Genetic Counseling, we're discussing the latest findings on PGT-A testing and what it means for embryo selection and fertility treatment: and this is fascinating!

Meaghan joins me to discuss a fascinating new article titled "New PGT-A Test Shows that Nearly All Blastocysts and Fetal Tissue are Mosaic." We'll break down what this means for fertility treatment, embryo selection, and how patients can use this information to make the best decisions for their family-building journey.

In this episode, we cover:

What PGT-A testing does and how its sensitivity has evolved
What mosaicism is and why nearly all embryos exhibit it
How new research is changing the way we interpret mosaic results
What these findings mean for embryo selection and transfer decisions
How fertility patients can advocate for themselves and make informed choices
