Euploid

What Is

Euploid?

A euploid cell or embryo has the normal number of 46 chromosomes. This means it has an exact multiple of a single set of normal 23 unpaired chromosomes found in healthy sperm and egg cells. Euploid embryos have much greater chances of implanting successfully, higher chances of successful pregnancies, and reduced rates of miscarriage.

In contrast, an aneuploid embryo (or one with an abnormal number of chromosomes) accounts for increased rates of miscarriages, birth defects, and implantation failure.
