Is IVF More Successful With PGT?

If you’re wondering whether IVF is successful with PGT, the answer is not simply yes or no. PGT can help identify certain chromosome or genetic abnormalities in embryos before transfer, but it does not guarantee pregnancy or a live birth. Whether it improves your IVF outcome depends on your age, fertility history, embryo numbers, and the type of PGT being considered.

What Is PGT and How Does It Work With IVF?

Preimplantation Genetic Testing (PGT) is a group of laboratory tests used to examine embryos created through IVF before an embryo is transferred to the uterus.

During IVF, eggs are collected and fertilised in a laboratory. The resulting embryos are allowed to develop, usually to the blastocyst stage, which is around day 5 or 6. A small number of cells can then be removed from the embryo for genetic analysis.

At Almond Blossoms, PGT is part of an advanced reproductive genetics approach that can help couples make more informed decisions about embryo transfer.

What does PGT actually test for?

There are different types of PGT, and they answer different questions:

• PGT-A: Looks for abnormal numbers of chromosomes, known as aneuploidy.
• PGT-M: Tests for a specific inherited genetic condition when there is a known risk in the family.
• PGT-SR: Looks for certain structural chromosome rearrangements.

For people asking whether IVF is more successful with PGT, PGT-A is usually the type being discussed because it is intended to help identify embryos with the expected number of chromosomes.

However, PGT is not a general health check of an embryo. It cannot predict every aspect of a future pregnancy or a baby’s health.

Does PGT improve embryo quality?

Not exactly.

PGT does not make an embryo genetically healthier. Instead, it provides additional information about the cells tested from an embryo.

That distinction is important.

Think of PGT as an information tool, rather than a treatment that improves the embryo itself.

Is IVF Successful With PGT? What the Evidence Says

PGT may be useful for some IVF patients, but it has not been proven to increase live-birth rates for everyone undergoing IVF. This is one of the most important points to understand before paying for genetic testing.

So, if you’re searching “IVF successful with PGT,” it would be misleading to say that PGT automatically makes an IVF cycle more successful.

Why can PGT still be helpful?

Although PGT-A does not guarantee a higher cumulative live-birth rate, it can provide useful information about embryo chromosome status.

For selected patients, this may help with:

• Choosing between embryos available for transfer
• Avoiding transfer of embryos identified as aneuploid
• Planning treatment when age-related chromosome abnormalities are a concern
• Reducing the number of embryo transfers needed in some circumstances
• Supporting more informed discussions after previous IVF outcomes

This is why your fertility specialist should look at your individual circumstances rather than treating PGT as a standard add-on to every IVF cycle.

Who May Benefit From PGT-A During IVF?

There is no single age or diagnosis that automatically means you should have PGT-A.

Instead, your fertility specialist may consider factors such as your age, reproductive history, number of embryos expected, previous IVF outcomes, and whether there is a specific genetic concern.

1. Patients of advanced reproductive age

As egg age increases, the proportion of embryos with chromosome abnormalities generally increases.

This can make embryo chromosome screening a consideration for some patients in their late 30s or 40s.

However, older age alone does not mean PGT-A will definitely increase your chance of a live birth.

2. Couples with a known inherited genetic condition

If you or your partner carries a known genetic condition, PGT-M may be considered.

PGT-M is different from PGT-A.

Rather than looking generally at chromosome numbers, it is designed to test embryos for a particular inherited condition.

This can be an important option for couples who have a known risk of passing a genetic disorder to their child.

3. Couples with a history of genetic concerns

If previous pregnancies or genetic testing have raised concerns about a chromosomal or inherited condition, your specialist may discuss whether PGT could be relevant.

Genetic counselling can be particularly valuable here because the right test depends on the specific genetic situation.

4. Patients who have had previous IVF difficulties

After unsuccessful IVF, it can be tempting to add every available technology to the next cycle.

But more testing is not automatically better.

If you’ve experienced repeated implantation problems or miscarriage, your specialist should consider the whole picture, including embryo development, uterine factors, age, ovarian response, and other relevant findings.

Does PGT Increase IVF Success Rate or Just Help Select Embryos?

This is one of the most important distinctions.

PGT-A can help identify embryos with a chromosome result that may be more suitable for transfer, but it does not increase the biological quality of the embryos created during IVF.

Your IVF outcome still depends on several factors.

Factors that influence IVF success include:

• Age: Egg quality and chromosome abnormalities are strongly associated with reproductive age.
• Ovarian reserve: Tests such as AMH (Anti-Müllerian Hormone) and antral follicle count can help estimate ovarian reserve, although they do not directly predict whether an IVF cycle will produce a live birth.
• Number of eggs retrieved: More eggs may provide more opportunities to create embryos, although quantity does not guarantee quality.
• Embryo development: Not every fertilised egg reaches the blastocyst stage.
• Sperm factors: Sperm count, movement and shape can influence fertilisation and embryo development.
• Uterine health: The uterus and endometrial lining need to be appropriately assessed for embryo transfer.
• Underlying fertility diagnosis: Endometriosis, tubal problems, ovulation disorders and other conditions can affect treatment.
• Laboratory and clinical factors: Embryology practices and the overall IVF process also matter.

This is why comparing two patients and saying, “One had PGT and the other didn’t, so PGT caused the better result,” can be misleading.

PGT cannot guarantee pregnancy

Even an embryo reported as euploid– meaning it has the expected chromosome number based on the cells tested- does not guarantee implantation or a healthy live birth.

The test examines a small sample of cells from the embryo. It is valuable information, but it is not a crystal ball.

What Are the Possible Advantages and Limitations of PGT?

Before deciding whether PGT is right for you, it helps to consider both sides.

Potential advantages

PGT may:

• Provide additional genetic information about embryos
• Help identify embryos with chromosome abnormalities before transfer
• Be particularly relevant in selected patients with increased reproductive age
• Help couples at risk of specific inherited genetic conditions
• Support more informed embryo-transfer decisions
• Potentially reduce some unsuccessful embryo transfers in selected circumstances

Potential limitations

PGT may also:

• Add cost to an IVF treatment plan
• Require embryo biopsy
• Require embryos to reach the appropriate stage for testing
• Result in embryos being reported as aneuploid, mosaic or having no clear result
• Reduce the number of embryos available for transfer
• Delay transfer because embryos are generally frozen while genetic results are obtained
• Not improve cumulative live-birth rates for every patient

This balanced discussion is important because fertility treatment involves not only medical decisions but also financial and emotional investment.

Is PGT Worth It With IVF? Questions to Ask Your Fertility Specialist

Rather than asking only, “Will PGT make my IVF successful?”, consider asking questions that relate directly to your situation.

1. Why are you recommending PGT for me?

There should be a clear clinical reason for considering the test.

2. Which type of PGT do I need?

PGT-A, PGT-M and PGT-SR have different purposes.

3. How many embryos are we likely to have available for testing?

The potential value of PGT can depend partly on how many blastocysts are available.

4. What happens if the result is mosaic?

A mosaic embryo contains cells showing different chromosome results within the tested sample. These results can be complex and should be discussed carefully with your fertility and genetics team.

5. What happens if no embryo is suitable for transfer?

This is an emotionally difficult possibility that should be discussed before testing.

Understanding possible outcomes can help you prepare for treatment rather than being surprised by the results.

6. What will PGT change about my treatment plan?

The most useful question is not simply whether PGT is available, but whether the information it provides is likely to change a decision in your treatment.

At Almond Blossoms, fertility decisions can be discussed alongside psychological support when treatment uncertainty becomes emotionally difficult. The clinic’s integrated model combines fertility treatment with wellbeing services, including individual and couples therapy.
