Mosaic embryo
An embryo containing a mixture of normal and chromosomally abnormal cells, identified through PGT-A testing.
In plain English
It's an embryo where PGT-A testing finds a mix of normal cells and cells with chromosome differences, rather than a clear-cut result either way.
Why it matters
Some mosaic embryos can still lead to healthy pregnancies, so a mosaic result usually means a detailed conversation with a genetic counsellor about the specific findings.
