Why is PGT Testing Recommended During IVF Treatment?

Advances in assisted reproductive technology have improved fertility treatment outcomes, offering new hope to couples experiencing infertility. One such innovation is Preimplantation Genetic Testing (PGT), which examines embryos for specific genetic or chromosomal abnormalities before embryo transfer during an IVF cycle. 

At Shivam IVF, treatment plans are personalized based on each patient's needs, and PGT may be recommended in selected cases. For couples searching for the Best IVF Hospital in Delhi, understanding PGT can help them make informed decisions about their IVF treatment with their fertility specialist

What Is PGT Testing?

Preimplantation Genetic Testing (PGT) is a laboratory procedure performed on embryos created through IVF. A few cells are carefully removed from a developing embryo and analyzed for specific chromosomal or genetic conditions, depending on the type of PGT being performed.

PGT may be recommended for selected patients based on their medical history and clinical needs. It is not necessary for every IVF cycle, and the decision should always be made in consultation with a qualified fertility specialist.

How Is PGT Performed?

PGT is carried out after embryos have developed in the laboratory.

The process generally includes:

• Egg retrieval and fertilization through IVF.

• Embryo development over several days.

• Embryo biopsy performed by experienced embryologists.

• Genetic analysis in a specialized laboratory.

• Review of results by the fertility team.

• Selection of suitable embryo(s) for transfer, when appropriate.

The embryo biopsy is performed using advanced laboratory techniques designed to preserve embryo viability.

1. Helps Identify Chromosomal Abnormalities

One of the primary reasons for recommending PGT is to identify embryos with chromosomal abnormalities.

Benefits include:

• Screening for abnormal chromosome numbers.

• Supporting informed embryo selection.

• Potentially reducing the chance of transferring embryos with certain chromosomal conditions.

2. May Improve Embryo Selection

Choosing an embryo involves evaluating several factors, including its development and, in selected cases, genetic testing results.

PGT can assist by:

• Providing additional information alongside embryo morphology.

• Supporting evidence-based clinical decision-making.

• Helping prioritize embryos for transfer when clinically appropriate.

3. May Reduce the Risk of Certain Genetic Disorders

For couples with a known inherited genetic condition, specific types of PGT may help identify embryos that do not carry the targeted condition.

This may be relevant for:

• Single-gene disorders.

• Certain inherited conditions identified through genetic counseling.

• Families with a documented genetic disease.

4. May Be Recommended After Recurrent Pregnancy Loss

• Repeated miscarriages can have multiple causes, including chromosomal abnormalities in embryos.

• In selected cases, fertility specialists may recommend PGT to provide additional information that could assist in planning future embryo transfers.

• A thorough evaluation is important, as recurrent pregnancy loss has many possible causes.

Couples seeking guidance from the Best IVF Hospital in Delhi often discuss PGT with their fertility specialist to determine whether this advanced testing is appropriate for their individual IVF journey.

5. May Benefit Couples with Previous IVF Failures

When previous IVF cycles have not resulted in pregnancy, doctors may review several contributing factors.

PGT may be considered as part of a broader evaluation that includes:

• Embryo quality.

• Uterine health.

• Hormonal factors.

• Genetic considerations.

The decision is individualized and based on the patient's overall fertility assessment.

6. May Be Considered for Advanced Maternal Age

• As maternal age increases, the likelihood of chromosomal abnormalities in eggs also rises.

• For some women, particularly those of advanced maternal age, PGT may provide additional information during embryo selection.

• The recommendation depends on individual medical history and should be made after consultation with a fertility specialist.

7. Supports Personalized Fertility Care

Every IVF journey is unique.

At Shivam IVF, treatment plans are designed according to factors such as:

• Age.

• Fertility history.

• Medical conditions.

• Previous treatment outcomes.

• Individual reproductive goals.

8. Provides Additional Information for Clinical Decision-Making

PGT offers genetic information that complements other clinical findings.

This may help the fertility team:

• Discuss treatment options.

• Plan embryo transfer timing.

• Consider embryo freezing strategies when appropriate.

• Counsel patients about available choices.

9. Encourages Informed Family Planning

• For couples with a known family history of inherited disorders, genetic counseling combined with PGT may provide valuable information before pregnancy.

When choosing the Best IVF Hospital in Delhi, many couples look for advanced genetic testing options, experienced fertility experts, and personalized care to make informed decisions throughout their parenthood journey.

10. Reflects the Use of Advanced Reproductive Technology

PGT represents one of several innovations available in modern IVF laboratories.

Clinics offering advanced fertility services may provide access to technologies such as:

• Time-lapse embryo monitoring.

• Embryo cryopreservation.

• ICSI (Intracytoplasmic Sperm Injection).

• Assisted hatching, where clinically indicated.

• Genetic testing options for selected patients.

Who May Be a Candidate for PGT?

Your fertility specialist may discuss PGT if you have:

• Advanced maternal age.

• A history of recurrent pregnancy loss.

• Multiple unsuccessful IVF cycles.

• A known inherited genetic condition in one or both partners.

• A previous pregnancy affected by a specific genetic disorder.

• Genetic test results suggesting an increased risk of transmitting certain conditions.

Questions to Ask Your Fertility Specialist About PGT

Before deciding on PGT, consider discussing:

• Is PGT recommended in my situation?

• Which type of PGT, if any, is appropriate?

• What conditions can the test identify?

• What are the limitations of the test?

• Will PGT change my treatment plan?

• What additional counseling may be needed?

Final Thoughts

Preimplantation Genetic Testing (PGT) is an advanced IVF technique that helps identify certain genetic or chromosomal abnormalities in embryos before transfer. Although PGT can benefit selected patients, it is recommended only after a thorough medical evaluation and appropriate genetic counseling. 

At Shivam IVF, treatment plans are personalized to each patient's needs, combining evidence-based care with compassionate support. If you're looking for the Best IVF Hospital in Delhi, consider factors such as experienced fertility specialists, advanced technology, transparent communication, and individualized treatment for a well-informed fertility journey.
