Preimplantation Genetic Testing Q&A

What is preimplantation genetic testing?

Preimplantation genetic testing is available to test embryos for chromosomal abnormalities. This testing is done before Dr. Meng transfers the embryos into your uterus as part of in-vitro fertilization treatments (IVF).

Chromosomal abnormalities can indicate if the embryo has a disorder like Down syndrome or if you’re a carrier of a genetic disease or disorder that you or your partner could pass along to your child during pregnancy.

Why would I need preimplantation genetic testing?

Preimplantation genetic testing of embryos increases the live-birth rate. It reduces your risk of miscarriage due to genetic problems in the fetus.

You might need genetic testing if you’ve had repeated miscarriages or if you have a known genetic disease or disorder that puts your child at risk.

You might also need testing if you’re 35 or older, have underlying ovarian dysfunction, or a history of failed fertility treatments.

What’s involved in preimplantation genetic testing?

Before embryos are ready for testing, they develop in an incubator until they reach the blastocyst stage, generally 5-7 days after fertilization occurs in the medical lab.

Dr. Meng removes 5-7 cells from the trophectoderm, part of the embryo that will later become the placenta. She sends the cells to a lab that tests for chromosomal numbers.

The embryos with normal chromosomal numbers that are free of disease are what Dr. Meng transfers into your uterus to achieve a viable pregnancy.

Are there risks with preimplantation genetic testing?

As with any medical procedure, certain risks are involved with preimplantation genetic testing. However, the handling of the embryo that testing requires poses a low risk of damage.

Because the embryo being tested needs to be frozen after Dr. Meng removes the cells, there’s a low risk of losing the embryo during the freezing and thawing processes.

Dr. Meng discusses your options and what to expect from preimplantation genetic testing as part of your consultation for IVF treatments.
