Can PGT Improve IVF Outcomes?

Embryo transfer is the most anticipated part of the in vitro fertilization (IVF) process. At this step, the fertility specialist transfers the viable embryos to the intended mother’s uterine lining. However, this does not automatically mean that the pregnancy will succeed. Factors like genetic abnormalities may affect the embryo’s implantation and development. Additionally, there is a possibility that the child inherits a condition from the parent. This is where preimplantation genetic testing (PGT) comes in. PGT can provide information about the embryos’ genetic health, protecting the next generation. Here are the 3 benefits of preimplantation genetic testing to consider.


1. Identifies chromosomally normal embryos

Preimplantation genetic testing allows fertility specialists to screen embryos for chromosomal abnormalities that can cause significant health problems. A healthy baby should get 23 chromosomes from the mom and 23 from the dad. If something goes wrong at conception, the baby can end up with 1 more or 1 less, causing problems like Down syndrome. If the doctor detects any abnormality in the embryo’s chromosomes, a different embryo can be selected for transfer. This approach reduces the chances of miscarriage and ensures that the transferred embryo is chromosomally normal.

2. Aids in family balancing

The use of PGT can also help families achieve a desired gender ratio. For example, couples wanting to have 2 boys can use a PGT test to select only healthy male embryos. Similarly, patients who wish to conceive a girl can choose only the unaffected female embryos to transfer to the womb. In this way, PGT can help balance the family’s male and female gene pool.

3. Avoids hereditary disease

Using PGT to test embryos, couples can significantly increase the chances of having a healthy baby not at risk of hereditary diseases. By screening and selecting only the unaffected embryos, couples reduce the risk of passing down a genetic disorder, such as Tay-Sachs disease and sickle cell anemia. As a result, the couple can have a healthy child with fewer health risks and disabilities in the future. Thus, PGT can be a helpful tool in protecting the health of future generations.

That’s not all

There are several other benefits for couples who undergo preimplantation genetic testing. Since PGT helps identify the healthiest embryos to transfer, couples could go through the pregnancy with less anxiety. Couples who undergo PGT and select the best embryo for transfer can also achieve the goal of having a baby quicker without going through multiple IVF cycles. This means saving time and money in the long run, which can be a deciding factor for many couples considering fertility treatment.

A healthier generation

Preimplantation genetic testing improves IVF success rates. With accurate and comprehensive information about the embryos’ genetic status, couples can choose the ideal embryo most likely to lead to a successful pregnancy and healthy baby. A simple test can guarantee a generation of healthy babies.
