Preimplantation Genetic Testing (PGT) is an advanced laboratory technique used during IVF to examine embryos for specific genetic or chromosomal findings before an embryo is transferred to the uterus. PGT may be considered when there is a known genetic risk, certain reproductive challenges, or a specific clinical reason to obtain additional information about embryos. However, PGT is not necessary for every IVF patient.
At Almond Blossoms Fertility & Wellbeing Centre in Dubai, PGT is considered as part of an individualized fertility treatment plan based on a couple's reproductive history, genetic background and treatment goals.
Key Takeaways
- PGT is performed on embryos created through IVF before embryo transfer.
- PGT-A, PGT-M and PGT-SR are designed to answer different genetic questions.
- PGT can provide valuable information but does not guarantee pregnancy or a healthy baby.
- Whether PGT is appropriate depends on your individual medical and genetic circumstances.
What Is Preimplantation Genetic Testing?
Preimplantation Genetic Testing is a laboratory-based procedure performed during an IVF cycle.
After eggs are fertilized and embryos develop in the laboratory, embryos can reach the blastocyst stage, usually around day 5 or 6. A small sample of cells may then be taken from the embryo and analyzed for the specific genetic or chromosomal condition being investigated.
The embryo is typically cryopreserved while testing is completed.
The results can then provide additional information to the fertility team when considering which embryos may be appropriate for transfer.
Importantly, PGT does not examine every possible genetic or medical condition. The information obtained depends on the specific type of PGT performed.
Why Is PGT Used During IVF?
One of the main reasons couples consider PGT is to obtain additional genetic information about embryos before transfer.
Depending on the circumstances, PGT may help:
- Identify certain chromosome abnormalities
- Test embryos for a known inherited genetic condition
- Identify certain structural chromosome abnormalities
- Reduce the risk of transferring an embryo affected by a specific genetic condition
- Support reproductive decision-making for couples with known genetic risks
However, PGT should be viewed as an additional testing option rather than a guarantee of IVF success.
Who Should Consider PGT Before IVF?
There is no universal rule that says every IVF patient should have PGT.
Your fertility specialist may discuss PGT when your medical or genetic history suggests that testing could provide useful information.
1. Couples With a Known Inherited Genetic Condition
PGT-M may be considered when one or both partners carry a known genetic condition.
Examples can include certain forms of:
- Thalassemia
- Cystic fibrosis
- Sickle cell disease
- Other single-gene disorders
In these situations, PGT-M can be designed to test embryos for the specific condition.
This can be particularly important for couples who want to understand their reproductive options before embryo transfer.
2. Couples With a Known Chromosomal Rearrangement
Some people carry structural chromosome changes such as translocations or inversions.
Although the person carrying the rearrangement may be healthy, the chromosome change can affect the genetic balance of embryos and may contribute to reproductive difficulties.
PGT-SR is specifically designed to assess embryos for certain structural chromosome abnormalities.
3. Couples With Previous Pregnancy Losses
Repeated pregnancy loss can have many possible causes.
Chromosomal abnormalities in embryos are one potential factor, although they are not the only explanation.
Depending on your medical history, your fertility specialist may discuss whether genetic evaluation or PGT could be appropriate.
It is important not to assume that PGT is automatically the solution for recurrent miscarriage. A detailed fertility assessment should come first.
4. Patients With Previous IVF Failures
If previous IVF cycles have not resulted in pregnancy, your fertility specialist may review multiple factors, including:
- Embryo development
- Egg and sperm factors
- Uterine factors
- Hormonal factors
- Embryo transfer
- Genetic or chromosomal considerations
In selected cases, PGT-A may be discussed as one part of the overall treatment strategy.
5. Couples Concerned About Chromosomal Abnormalities
PGT-A, or Preimplantation Genetic Testing for Aneuploidy, examines embryos for abnormalities in chromosome number.
Aneuploidy refers to an abnormal number of chromosomes.
PGT-A may provide additional information about embryo chromosome status, but it is important to understand that it is not recommended automatically for every IVF patient.
The potential value of PGT-A depends on factors such as reproductive history, age, embryo availability and the specific clinical situation.
What Are the Different Types of PGT?
Understanding the difference between PGT tests is important because each test has a different purpose.
PGT-A
PGT-A = Preimplantation Genetic Testing for Aneuploidy
It evaluates embryos for abnormalities involving chromosome number.
It may be discussed in selected IVF situations where information about embryo chromosome status could be clinically useful.
PGT-M
PGT-M = Preimplantation Genetic Testing for Monogenic Disorders
This test is designed to investigate a specific single-gene condition.
It may be considered when there is a known inherited genetic condition in the family or when one or both reproductive partners carry a particular genetic variant.
PGT-SR
PGT-SR = Preimplantation Genetic Testing for Structural Rearrangements
This testing is used when there is a known structural chromosome rearrangement, such as a translocation or inversion.
The goal is to identify embryos with relevant chromosome abnormalities associated with the known rearrangement.
How Does PGT Work With IVF?
PGT cannot be performed without creating embryos through IVF.
A simplified treatment pathway is:
Step 1: Fertility Assessment
Your fertility specialist reviews your reproductive and medical history and determines whether genetic testing may be appropriate.
Step 2: Ovarian Stimulation
Fertility medication is used to stimulate the ovaries to develop multiple eggs.
Step 3: Egg Collection
Mature eggs are collected during the IVF procedure.
Step 4: Fertilisation
Eggs are fertilized with sperm in the laboratory. Depending on the circumstances, IVF or ICSI may be used.
Step 5: Embryo Development
The embryos are monitored as they develop in the laboratory.
Step 6: Blastocyst Biopsy
When appropriate embryos reach the blastocyst stage, a small number of cells may be removed for genetic analysis.
Step 7: Genetic Testing
The biopsy sample is analyzed according to the selected PGT test.
Step 8: Embryo Transfer
Once results are available, the fertility team discusses which embryo may be appropriate for transfer based on the overall clinical situation.

Does PGT Guarantee IVF Success?
No. PGT does not guarantee pregnancy, implantation, live birth or a healthy baby.
This is one of the most important points patients should understand before undergoing genetic testing.
PGT examines a specific genetic or chromosomal feature depending on the test performed. It does not eliminate every possible genetic, developmental or medical risk.
Even when an embryo receives a favorable PGT result, pregnancy may still not occur.
Factors such as maternal age, embryo development, uterine health, sperm factors and other reproductive factors can influence IVF outcomes.
Is PGT-A Recommended for Everyone Over 35?
Not necessarily.
Maternal age is associated with an increased likelihood of embryo aneuploidy, but age alone does not mean that PGT-A is automatically the best option.
The decision should consider:
- Age
- Number of embryos available
- Previous IVF outcomes
- Pregnancy history
- Genetic background
- Reproductive goals
- Overall fertility diagnosis
A personalized consultation is therefore more useful than relying on a single age cut-off.
Can PGT Detect All Genetic Diseases?
No.
This is another common misconception.
PGT only provides information related to the specific testing performed.
For example:
PGT-A → chromosome numberPGT-M → specific single-gene conditionPGT-SR → certain structural chromosome abnormalities
PGT does not guarantee that an embryo is free from every possible genetic, developmental or medical condition.
Prenatal screening and/or diagnostic testing may still be recommended during pregnancy.
What Are the Benefits of PGT?
Depending on the patient's circumstances, PGT may offer several potential advantages.
Potential benefits include:
- Additional information about embryos
- Testing for certain inherited genetic conditions
- Supporting reproductive decision-making
- Helping reduce the chance of transferring an embryo affected by a known genetic condition
- Providing information that may be useful when selecting embryos for transfer
The value of PGT should always be weighed against its limitations, costs and the number of embryos available for testing.
What Are the Limitations of PGT?
PGT is an advanced reproductive technology, but it is not a perfect test.
Potential limitations include:
- Not every embryo may reach the blastocyst stage
- There may be no embryos suitable for testing
- Results can sometimes be complex
- Mosaic findings may require specialist interpretation
- PGT does not test for every genetic condition
- PGT does not guarantee pregnancy
- PGT does not eliminate the need for appropriate prenatal care
For these reasons, genetic counselling and fertility specialist guidance can be valuable.
