Getting your PGT-A report back can feel overwhelming, especially with unfamiliar terms like “euploid,” “aneuploid,” or “mosaic” scattered across the page. Many patients tell us they read the report several times over, unsure what it actually means for their next step. At Aspire Fertility Center, we believe understanding your PGT-A report shouldn’t require a medical degree. This blog breaks down exactly what these results mean, so you can walk into your next consultation with clarity instead of confusion.
What Does a PGT-A Report Tell You About Your Embryos?
A PGT-A report tells you the chromosomal status of each tested embryo, helping your fertility team decide which ones are suitable for transfer.
The Main Classifications You’ll See
Most PGT-A reports classify embryos into a few key categories: euploid (chromosomally normal), aneuploid (chromosomally abnormal), and sometimes mosaic (a mix of both normal and abnormal cells). Each classification carries different implications for whether — and how confidently — an embryo can be considered for transfer.
Why This Information Matters for Embryo Transfer
A PGT-A report isn’t just a diagnostic formality — it directly shapes your treatment plan. Knowing which embryos are chromosomally normal helps prioritize the ones most likely to lead to a successful, ongoing pregnancy, rather than transferring embryos without this insight and hoping for the best.
Euploid vs Aneuploid Embryo — What’s the Difference?
Understanding euploid vs aneuploid embryo classifications is central to making sense of your PGT-A report.
What Makes an Embryo Euploid
A euploid embryo has the exact, correct number of chromosomes — 23 pairs — required for a healthy pregnancy outcome. When comparing euploid vs aneuploid embryo results, euploid embryos are generally considered the most viable option for transfer, since they carry the expected chromosomal makeup. This is why, when multiple embryos are available, doctors typically prioritize euploid ones first.
What Makes an Embryo Aneuploid — Monosomy and Trisomy Explained
An aneuploid embryo has an abnormal number of chromosomes, either missing or extra. This can show up in two main ways: monosomy, where a single chromosome from a pair is missing, and trisomy, where there’s an extra chromosome — three copies instead of two. In the euploid vs aneuploid embryo comparison, aneuploid results are the ones that typically raise concern for viability.
What Happens With an Aneuploid Result?
An aneuploid classification on your PGT-A report carries specific, important implications for treatment.
Why Aneuploid Embryos Aren’t Selected for Transfer
Aneuploid embryos are generally considered non-viable, which is why they’re typically not selected for embryo transfer. This isn’t a judgment on the embryo itself — it simply reflects that the chromosomal makeup makes a successful pregnancy far less likely.
Potential Outcomes if Transferred Anyway
If an aneuploid embryo were transferred, it can lead to failed implantation, early miscarriage, or a biochemical pregnancy, where a pregnancy is detected briefly through hormone levels but doesn’t progress. This is exactly why your PGT-A report plays such a central role in deciding which embryo to transfer first.
PGT-A Mosaic Embryo — A Third Classification to Know
Beyond euploid and aneuploid, some PGT-A reports include a pgt-a mosaic embryo classification, which sits somewhere in between.
A Middle Category Between Euploid and Aneuploid
A pgt-a mosaic embryo contains a mix of both normal and abnormal cells, rather than being entirely one or the other. This classification tends to raise the most questions, since it doesn’t fit neatly into a simple “viable” or “non-viable” category.
How Doctors Typically Approach Mosaic Results
When a pgt-a mosaic embryo is identified, doctors often weigh factors like the type and percentage of abnormal cells, along with whether other euploid embryos are available. In some cases, mosaic embryos may still be considered for transfer, particularly when no fully euploid embryos are available, but this decision is always made carefully and individually, factoring in the couple’s specific history and preferences.
How to Read Your PGT-A Report With Your Doctor
A PGT-A report is easiest to understand in conversation with your fertility specialist, rather than trying to interpret it alone.
Questions Worth Asking During Your Results Consultation
When reviewing your PGT-A report, it helps to ask: How many embryos were tested, and what were the results for each? Do I have any mosaic results, and what does that mean for my options? Which embryo does my doctor recommend transferring first, and why? These questions turn a confusing document into a clear, actionable conversation.

Frequently Asked Questions
Q1: What does a PGT-A report actually show?
A1: A PGT-A report shows the chromosomal status of each tested embryo, classifying them as euploid, aneuploid, or sometimes mosaic, helping guide which embryo is best suited for transfer.
Q2: What’s the difference between euploid vs aneuploid embryo results?
A2: In euploid vs aneuploid embryo results, euploid means the embryo has the correct number of chromosomes, while aneuploid means it has extra or missing chromosomes, which generally makes it unsuitable for transfer.
Q3: What is a pgt-a mosaic embryo?
A3: A pgt-a mosaic embryo contains a mix of both normal and abnormal cells. It doesn’t fall clearly into euploid or aneuploid categories, and decisions around it are made on a case-by-case basis.
Q4: Can an aneuploid embryo still result in a pregnancy?
A4: Aneuploid embryos are generally non-viable and are typically not selected for transfer, since they can lead to failed implantation, early miscarriage, or a biochemical pregnancy.
Q5: What should I ask my doctor when reviewing my PGT-A report?
A5: Ask how many embryos were tested, what the results were for each, whether any came back mosaic, and which embryo your doctor recommends transferring first and why.
