Is PGT Worth It? Benefits, Limitations and Costs of Genetic Testing in IVF

Preimplantation Genetic Testing (PGT) may be worth considering for some IVF patients, particularly when there is a known genetic condition or a specific reproductive reason for testing. However, PGT is not necessary for everyone and does not guarantee pregnancy or a healthy baby. Understanding its benefits, limitations, and costs can help you decide whether it fits your individual fertility treatment plan.

At Fertility & Wellbeing Centre in Dubai, patients can discuss PGT as part of an individualized IVF treatment approach.

Key Takeaways

  • PGT can provide additional genetic or chromosomal information about embryos.
  • PGT may be particularly valuable when there is a known genetic risk.
  • It has limitations and cannot guarantee IVF success.
  • Cost should be considered alongside the potential clinical value of the information obtained.
  • The decision should be personalized rather than based on age or internet recommendations alone.

What Is PGT?

Preimplantation Genetic Testing is a specialized laboratory procedure performed during IVF.

After eggs are fertilized and embryos develop in the laboratory, an embryo may undergo biopsy at the blastocyst stage. A small sample of cells is analyzed for the specific genetic or chromosomal characteristic being investigated.

There are several types of PGT, including:

PGT-A

Used to assess chromosome number, specifically aneuploidy.

PGT-M

Used to test for a specific monogenic or single-gene disorder.

PGT-SR

Used to assess certain structural chromosome rearrangements.

Each test has a different purpose, so the first question should not simply be “Should I have PGT?”

A better question is:

“Would PGT provide useful information for my particular IVF situation?”

Is PGT Worth It for Everyone?

No.

PGT is not a routine requirement for every IVF cycle.

The potential value of PGT depends on factors such as:

  • Your age
  • Previous fertility treatment
  • Previous pregnancy history
  • Number of embryos expected
  • Family genetic history
  • Known genetic conditions
  • Chromosomal findings
  • Your reproductive goals

For example, a couple carrying a known genetic condition may have a very different reason for considering PGT-M than an IVF patient considering PGT-A.

This is why PGT decisions should be individualized.

Potential Benefits of PGT

1. It Provides Additional Embryo Information

One of the biggest potential benefits of PGT is that it provides information that may not be available through routine embryo assessment alone.

Embryologists can assess embryo development and appearance, but genetic testing can provide additional information about the specific genetic or chromosomal feature being tested.

This can help inform discussions about embryo transfer.

2. PGT-M Can Help With Known Genetic Risks

For couples who have a known risk of passing on a particular single-gene condition, PGT-M can be an important reproductive option.

PGT-M is specifically designed around the genetic condition being investigated.

It may allow affected embryos to be identified before embryo transfer.

This can be particularly meaningful for couples who have previously experienced a pregnancy or child affected by a genetic disorder.

3. PGT-SR Can Help With Certain Chromosomal Rearrangements

Some individuals carry structural chromosome rearrangements without experiencing obvious health problems themselves.

However, these rearrangements can affect reproductive outcomes.

PGT-SR can be considered in selected circumstances to provide information about embryos in relation to the known structural chromosome rearrangement.

4. PGT-A Can Provide Chromosome Information

PGT-A examines embryos for abnormalities in chromosome number.

Chromosomal abnormalities are an important consideration in human reproduction, particularly because the likelihood of aneuploid embryos changes with maternal age.

However, this does not mean that every older IVF patient automatically needs PGT-A.

The American Society for Reproductive Medicine notes that PGT-A has not been established as a universal screening test for all IVF patients.

Does PGT Increase IVF Success Rates?

This is where patients need to be particularly careful.

It would be inaccurate to say:

“PGT guarantees a higher IVF success rate.”

It does not.

PGT provides specific genetic information, but pregnancy depends on many factors.

These can include:

  • Embryo characteristics
  • Uterine factors
  • Maternal age
  • Sperm factors
  • Endometrial conditions
  • Hormonal factors
  • Overall reproductive health

Therefore, PGT should not be marketed as a guarantee of IVF success.

What Are the Limitations of PGT?

Like every medical test, PGT has limitations.

PGT Does Not Test Everything

A PGT result relates to the specific testing performed.

For example, PGT-A does not mean that an embryo has been screened for every genetic disease.

Similarly, PGT-M is designed around a particular monogenic condition rather than every possible genetic disorder.

PGT Does Not Guarantee Implantation

Even an embryo with a favorable PGT result may not implant.

Embryo implantation involves complex biological processes that cannot be predicted by PGT alone.

PGT Does Not Guarantee a Healthy Baby

This is extremely important.

A favorable PGT result does not eliminate every possible genetic, developmental or medical risk.

Prenatal screening and, where appropriate, diagnostic testing may still be recommended during pregnancy.

Not Every IVF Cycle Produces Embryos for Testing

Patients sometimes assume that every egg collected during IVF will eventually become an embryo available for PGT.

That is not the case.

There may be attrition at multiple stages:

Eggs retrieved → mature eggs → fertilized eggs → developing embryos → blastocysts → biopsied embryos → testable embryos → embryos potentially suitable for transfer

Therefore, the number of eggs retrieved cannot be used to predict exactly how many embryos will ultimately be available for testing or transfer.

How Much Does PGT Cost in Dubai?

The cost of PGT in Dubai varies depending on several factors.

These may include:

  • Type of PGT
  • Number of embryos tested
  • Laboratory fees
  • Genetic testing requirements
  • Whether additional genetic work-up is required
  • IVF treatment costs
  • Medication
  • Embryo freezing and storage
  • Future frozen embryo transfer

For PGT-M, for example, additional laboratory preparation may sometimes be required because testing is designed around a specific genetic condition.

Therefore, patients should ask for a complete treatment estimate rather than looking only at the headline PGT price.

Important question to ask your clinic:

“Does the quoted PGT price include all laboratory and genetic-testing costs?”

This can help avoid unexpected expenses.

PGT Cost vs Potential Value

Instead of asking only:

“How much does PGT cost?”

consider asking:

“What clinical information will PGT provide, and how could that information affect my treatment decisions?”

For a couple with a known inherited condition, PGT-M may provide highly relevant reproductive information.

For another patient, the potential benefit may be less clear.

The value of testing therefore depends on the clinical context.

When Might PGT Be Particularly Relevant?

PGT may be discussed in situations such as:

Known inherited genetic condition

A couple has a known risk of passing a specific single-gene disorder to their child.

Known structural chromosome rearrangement

One partner carries a relevant chromosome rearrangement.

Specific reproductive history

A fertility specialist may discuss embryo genetic testing after considering previous reproductive outcomes and the patient’s overall situation.

Selected IVF cases

PGT-A may be considered when chromosome information could potentially help with embryo selection, after discussing its benefits and limitations.

When Might PGT Not Be the Best Choice?

There may be situations where PGT offers limited practical value.

For example:

  • Very few embryos are expected to be available
  • There is no clear indication for a particular PGT test
  • The patient has not yet completed an appropriate fertility assessment
  • The patient expects PGT to guarantee pregnancy
  • The patient believes PGT replaces prenatal testing

The decision should always be based on a realistic understanding of what the test can accomplish.

PGT and Embryo Selection

One reason patients consider PGT is to obtain additional information before embryo transfer.

However, genetic testing should be viewed as one part of embryo selection, not the only factor.

The fertility team may consider:

  • PGT results
  • Embryo development
  • Embryo morphology
  • Patient history
  • Uterine factors
  • Previous treatment outcomes

The final transfer strategy should therefore be individualized.

Should You Choose PGT-A Because of Your Age?

Age can be an important consideration, but it should not be the only factor.

The relationship between maternal age and embryo aneuploidy is well established, but the decision to perform PGT-A requires consideration of the complete clinical picture.

A fertility specialist may evaluate:

  • Your age
  • Ovarian reserve
  • Expected embryo number
  • Previous IVF cycles
  • Pregnancy history
  • Treatment goals

The question is not simply “Am I old enough for PGT-A?”

Instead:

“Would PGT-A provide meaningful information in my specific circumstances?”

Questions to Ask Before Choosing PGT

Before paying for PGT, consider asking your fertility specialist:

1. Why are you recommending PGT for me?

You should understand the specific clinical reason.

2. Which PGT test is appropriate?

PGT-A, PGT-M and PGT-SR are not the same.

3. What exactly can the test detect?

Ask your doctor to explain the scope of testing in simple terms.

4. How many embryos might be tested?

Your clinic can explain how embryo numbers may affect the treatment pathway.

5. What happens if all embryos are unsuitable?

Ask about alternative treatment options.

6. Are there additional costs?

Confirm laboratory, genetic counselling, testing, freezing and transfer costs.

7. Will I still need prenatal testing?

In many circumstances, appropriate prenatal screening or diagnostic testing remains important.

Final Verdict: Is PGT Worth It?

PGT can be worth considering when the information it provides has a clear clinical purpose.

For couples with a known inherited genetic condition, PGT-M may offer valuable reproductive information. For people with certain structural chromosome rearrangements, PGT-SR may be relevant. In selected IVF situations, PGT-A may provide additional information about embryo chromosome status.

But PGT is not a guarantee of IVF success, and it is not automatically necessary for every patient.

The best decision is one based on your individual fertility history, genetic circumstances, number of embryos, treatment goals and a clear understanding of the test’s benefits and limitations.

If you are considering PGT in Dubai, speak with a qualified fertility specialist to determine whether genetic testing could be appropriate for your IVF journey.

FAQs

Is PGT worth the extra cost?

It depends on the individual. PGT may provide valuable information in selected clinical situations, but the potential benefit should be weighed against its cost and limitations.

Does PGT guarantee pregnancy?

No. PGT cannot guarantee implantation, pregnancy or live birth.

Is PGT painful?

The genetic testing is performed on embryo biopsy samples in the laboratory. Patients do not undergo a separate painful procedure to have the embryo cells tested.

How many embryos are needed for PGT?

There is no universal minimum number, but the number of embryos available can affect how useful testing is and whether an embryo may ultimately be available for transfer.

Can PGT detect Down syndrome?

PGT-A can assess embryos for chromosome-number abnormalities involving chromosome 21, but it does not guarantee the absence of every genetic or medical condition. Prenatal testing remains important.

Is PGT-A better than regular IVF?

Not necessarily. PGT-A may be useful for selected patients, but it is not universally recommended for every IVF cycle.
