Euploid embryos have the correct number of chromosomes, which makes them more likely to result in a healthy pregnancy and baby.
By incorporating genetic testing into your IVF or surrogacy journey, you can identify euploid embryos and significantly improve your chances of achieving a successful pregnancy.
This article will explain everything you need to know about euploid embryos and their critical role in IVF cycles.

What Is a Euploid Embryo?
A euploid embryo is a genetically normal embryo with the correct number of chromosomes (46). This is the ideal embryo type to produce during IVF, as it has a strong chance of developing into a healthy baby. Euploid embryos are identified through a process called preimplantation genetic testing for aneuploidy (PGT-A), which screens for chromosomal abnormalities.
In contrast, an aneuploid embryo has an abnormal number of chromosomes, which can result in genetic disorders. PGT-A can detect conditions such as:
Down syndrome Turner syndrome Trisomy 13 Trisomy 18 And more
Success Rates of Euploid Embryos
According to a study from Reproductive Medicine Associates, individuals with three chromosomally normal embryos from IVF have a 94.9% chance of becoming pregnant. A 2020 study from the National Library of Medicine also reported a live birth rate of up to 70% for euploid embryos.
However, these success rates depend on several factors, including:
The timing of the embryo transfer The blastocyst’s morphology (which will develop into the embryo) Maternal age
Your fertility clinic can provide personalized information on your euploid embryo success rates and live birth probability.
Euploid Embryo vs. Blastocyst: What’s the Difference?
A blastocyst is a stage of embryo development, that occurs about five or six days after fertilization. It becomes an embryo approximately 10 to 12 days after the sperm fertilizes the egg. While a blastocyst can be euploid (genetically normal), a blastocyst refers to the stage of development, and euploid refers to the embryo's chromosomal status.
