What it means

PGT stands for Preimplantation Genetic Testing. It is a process used in IVF to check embryos for certain genetic or chromosome conditions before they are transferred into the uterus. This helps identify which embryos have a typical number of chromosomes and which may not.

When it’s used

It’s used after an embryo has developed, usually at the blastocyst stage. A small sample of cells is taken from the embryo and tested, while the embryo is usually frozen and kept for later use.

Why people get confused

Some people think PGT guarantees a successful pregnancy. But it only provides information about the embryo’s chromosomes. It does not ensure implantation or that pregnancy will happen.

Think of it this way

PGT is like checking the blueprint of an embryo before deciding to use it. It gives more information, but it doesn’t control what happens next.

What to expect

If PGT is done, there is usually a waiting period for results before deciding on transfer. Some embryos may be suitable for transfer, while others may not. Even with tested embryos, outcomes can still vary.
