Why don’t some embryos lead to pregnancy? Genetic testing can uncover the problem
When embryologists evaluate an embryo, they use strict criteria – they examine cell division, symmetry, and development dynamics. These are important factors, but they can’t see the embryo’s genetic profile with the naked eye. That’s where another team member comes in –the geneticist.
PGT & Success: Waiting for a positive test? This might help!
One of the main reasons why an embryo fails to result in pregnancy or leads to miscarriage is a tricky term – aneuploidy (an abnormal number of chromosomes). It’s not just difficult to pronounce, but it can also be the reason why an embryo doesn’t implant, the pregnancy ends prematurely, or the baby is born with a genetic condition. This is where preimplantation genetic testing (PGT) plays a key role. It helps detect chromosomal abnormalities before the embryo is transferred, allowing us to select the one most likely to implant successfully and develop into a healthy baby.
How does genetic embryo testing work?
If you’re wondering how this process works or whether it’s safe for the embryo, here’s a simple breakdown: Everything is done with great care, with one goal in mind – selecting the embryo with the best chance of a healthy development.
🔬 THE EMBRYO DEVELOPS IN THE LAB UNDER THE SUPERVISION OF EMBRYOLOGISTS
After fertilization, embryos develop for about 5–6 days. During this time, embryologists closely monitor their progress until they reach the blastocyst stage.
🧬 A FEW CELLS ARE SAFELY REMOVED WITHOUT HARMING THE EMBRYO
At this stage, the embryologist takes a few cells from the trophoectoderm – the part of the embryo that will later form the placenta. The inner cell mass, which will develop into the baby, remains untouched.
📊 GENETIC LAB ANALYZES THE EMBRYO'S DNA
The collected sample is sent to a genetic lab, where it undergoes detailed chromosomal analysis. Geneticists can determine whether the embryo has the correct number of chromosomes or carries any genetic disorders.
✅ SELECTING THE EMBRYO WITH THE BEST CHANCE OF SUCCESS
Based on the results, embryologists and doctors recommend the embryo with the highest probability of implantation and healthy development – a crucial step in achieving IVF success.
Is PGT right for you?
PGT is particularly beneficial for couples experiencing recurrent IVF failures, repeated miscarriages, or those concerned about genetic disorders. It is especially recommended for women over 35, as the risk of chromosomal abnormalities increases with age.
