PGT stands for Preimplantation Genetic Testing. It’s a special kind of testing done during IVF, where embryos are screened before they’re transferred to the uterus. 

In plain language: PGT helps doctors check if an embryo has the right number of chromosomes or if it carries specific genetic conditions before trying to get pregnant. Think of it like giving your future baby a quick health check before they’re even in the womb. 

How Does PGT Work? 

Here’s a quick step-by-step: 

1. You go through a regular IVF cycle. 

2. After fertilization, the embryos are grown in the lab for a few days. 

3. When they reach the blastocyst stage (usually around day 5), a few cells are gently removed from each embryo (biopsy). 

4. These cells are sent to a genetics lab for analysis. 

5. Meanwhile, the embryos are safely frozen while waiting for results. 

6. Once results are in, the healthiest embryos are chosen for transfer. 

And no,this doesn’t harm the embryo. It’s done very carefully by experienced professionals. 

Why Would Someone Want PGT? 

PGT isn’t always necessary, but it can be super helpful in certain situations.Here’s when doctors usually recommend it: 

1. Recurrent Miscarriages 

If you’ve had multiple miscarriages, PGT can help check if chromosomal issues might be the cause. 

2. Multiple Failed IVF Attempts 

Sometimes embryos look perfect under the microscope, but they still don’t implant. PGT can reveal if there are hidden genetic problems. 

3. Advanced Maternal Age 

As women age, the chance of chromosomal abnormalities (like Down syndrome) increases. PGT helps select embryos with the right number of chromosomes. 

4. Known Genetic Conditions 

If you or your partner are carriers of a specific inherited disease, PGT can help avoid passing it on. 

Is PGT 100% Accurate? 

No test is perfect, but PGT is very reliable when done in a qualified lab. Still, doctors usually recommend confirming the baby’s health later on with standard prenatal tests (like NIPT or amniocentesis), just to be extra sure. 

Is It Expensive? 

PGT is an extra cost on top of IVF, and prices vary depending on the country and clinic. 

Final Thoughts: Is PGT Right for You? 

PGT isn’t for everyone. But for couples dealing with fertility challenges or carrying known genetic risks, it can offer peace of mind and improve the chances of a healthy pregnancy.
