Why can two embryos both be genetically normal, both be labeled AA, and even be tested by the same genetics company… yet still have very different chances of leading to pregnancy?

In this episode of Taco Bout Fertility Tuesday, Dr. Mark Amols breaks down one of the biggest misunderstandings in IVF: the idea that “normal” means “equal.” He explains what PGT-A really tells us, why embryo grading is useful but limited, and how two embryos with the same label can still have very different biologic potential. He also dives into why IVF lab quality matters so much — from culture conditions and air handling to biopsy skill, freezing, thawing, and transfer technique.

If you have ever wondered why one euploid embryo works while another does not, or why some clinics may have better outcomes than others, this episode helps make sense of it all in a clear, patient-friendly way.
