Euploid

A euploid embryo has the expected 46 chromosomes in the cells tested. Euploid embryos have a higher chance of implanting than untested or aneuploid embryos, but a euploid result is not a guarantee: the biopsy samples only a few cells, and factors beyond chromosomes affect whether a pregnancy continues and whether a baby is healthy.

Also known as: normal embryo, chromosomally normal
