Good, Better, Best? Why IVF Embryo Grades Don’t Work Like Report Cards.

When you’re going through IVF, every update from the lab feels like a cliffhanger. One of the most suspenseful moments? Hearing your embryo’s grade. Suddenly, you’re handed letters and numbers like “5AA” or “3BC” that sound more like secret codes than life-changing news.

It’s tempting to think of embryo grading as a report card for your future family: an A equals success, and a C means trouble. But here’s the truth: embryo grades are not report cards, and they certainly don’t tell the whole story about your chances of having a healthy pregnancy.

Let’s look at what embryo grading really means, what it does not, and why your journey deserves more than a grading system.

What Is Embryo Grading?

Embryo grading is a system embryologists use to describe embryos based on how they look under a microscope. On Day 3, they check the number of cells, fragmentation, and symmetry. By Day 5, embryos are evaluated as blastocysts, where the inner cell mass (which becomes the baby) and the trophectoderm (which becomes the placenta) are graded separately.

So yes, embryos get “grades” like 5AA or 4BC. But unlike a report card from school, these grades do not measure overall achievement. They are simply a way for embryologists to identify embryos that appear more likely to implant.

Why Higher Doesn’t Always Mean Better

Here is where things get tricky. An embryo with an “AA” grade does not automatically lead to a healthy pregnancy. On the other hand, a “BC” embryo is not destined for failure. Many parents have welcomed babies from embryos that looked “average” in the lab.

That is because embryo grading only looks at appearance, not what is happening inside the embryo. Think of it like judging a book by its cover. You can get clues, but you do not know the full story.

This is why some fertility specialists recommend preimplantation genetic testing (PGT IVF). Unlike grading, which focuses on appearance, genetic testing during IVF can reveal whether an embryo has the correct number of chromosomes. According to the American Society for Reproductive Medicine (ASRM), this testing offers important insights that grading alone cannot provide.

What Embryo Grading Can and Cannot Do

What it can do:

• Help embryologists decide which embryos to transfer or freeze.
• Provide a snapshot of embryo development at a specific time.
• Offer context during your fertility consultation about possible next steps.

What it cannot do:

• Predict with certainty whether pregnancy will occur.
• Determine your future child’s health or traits.
• Replace the role of fertility testing or genetic testing during IVF.

Common Myths About Embryo Grading

Myth 1: Lower-graded embryos never work.
Truth: Many healthy pregnancies begin with embryos that were graded as “average.”

Myth 2: Grading is the same everywhere.
Truth: While general guidelines exist, grading has some subjectivity and may vary slightly between clinics.

Myth 3: If you do PGT IVF, grading is not important.
Truth: Both methods provide different insights. Grading looks at structure, while preimplantation genetic testing looks at chromosomes. Together, they give fertility specialists more information to work with.
