Pre-implantation genetic testing (PGT) is a game-changer for couples looking to enhance their chances of having a healthy baby. This process involves examining embryos for genetic issues before they are implanted in the uterus. The main goal? To minimize the risk of genetic disorders in the fetus, which can lead to miscarriages or complications in pregnancy. By identifying chromosomal abnormalities (PGS) or specific genetic mutations (PGD), PGT helps improve the likelihood of a successful pregnancy and can even reduce the chance of having multiple embryos implanted by using a single embryo transfer.
For couples undergoing fertility treatments, PGT can streamline the process, often resulting in fewer cycles of in vitro fertilization (IVF) and thereby cutting down on both time and costs. While the accuracy of PGT is quite high, it’s worth noting that it’s not foolproof. Prenatal testing is still advisable for pregnancies that result from embryos that have undergone genetic screening. Just remember, a positive test result doesn’t guarantee everything will go smoothly during pregnancy.
Types of PGT Available
Here’s a quick rundown of the types of PGT available at our clinics:
- PGT-A: This tests embryos for chromosomal abnormalities. Chromosome issues are a leading cause of IVF failures, and about 25% of embryos from women around 30 have these abnormalities. Assisted reproduction doesn’t increase this risk, but it allows for screening before implantation.
- PGT-M: This test screens for single-gene diseases, targeting specific genetic mutations that could be passed from parents to their children. Even couples who can conceive naturally may opt for this if there’s a family history of genetic disorders.
- PGT-SR: For those who carry balanced translocations, this test checks embryos to ensure they are not affected by unbalanced translocations, which can lead to serious health issues or miscarriages.

Conclusion
In summary, PGT is a valuable option for couples looking to enhance their chances of a healthy pregnancy by identifying genetic issues in embryos before implantation. While it offers high sensitivity and specificity, it’s not a guarantee, so prenatal testing remains an important step.
