In the rapidly advancing field of reproductive medicine, one innovation stands out as a game-changer for couples undergoing IVF — Preimplantation Genetic Testing (PGT). This cutting-edge technology has transformed how fertility specialists approach embryo selection, significantly improving the chances of a healthy pregnancy and successful childbirth.
For couples facing repeated IVF failures, genetic disorders, or unexplained infertility, PGT offers a ray of hope. By enabling the selection of genetically healthy embryos before implantation, it minimizes risks and maximizes outcomes.
According to leading fertility expert Dr. Sweta Gupta, IVF Specialist in Noida,
“PGT is not just a diagnostic tool—it is a strategic advancement that empowers couples to achieve safer, healthier pregnancies with higher confidence.”
What is Preimplantation Genetic Testing (PGT)?
Preimplantation Genetic Testing (PGT) is a specialized laboratory procedure performed during an IVF cycle to analyze the genetic makeup of embryos before they are transferred into the uterus.
During IVF:
- Eggs are retrieved and fertilized in a lab
- Embryos are allowed to develop for 5–6 days (blastocyst stage)
- A few cells are carefully biopsied from each embryo
- These cells are tested for genetic abnormalities
Only embryos that are genetically normal are selected for transfer.
Types of PGT: Understanding the Categories
PGT is broadly categorized into three types:
1. PGT-A (Preimplantation Genetic Testing for Aneuploidy)
Detects abnormal chromosome numbers (extra or missing chromosomes).
👉 Helps prevent:
- Down syndrome
- Turner syndrome
- Edwards syndrome
2. PGT-M (Monogenic Disorders)
Used when one or both parents carry a known genetic mutation.
👉 Detects conditions like:
- Thalassemia
- Cystic fibrosis
- Sickle cell anemia
3. PGT-SR (Structural Rearrangements)
Identifies chromosomal structural abnormalities such as translocations.
👉 Recommended for:
- Couples with recurrent miscarriages
- Known chromosomal rearrangements
Why PGT is the Future of IVF
PGT represents a shift from trial-and-error IVF to precision reproductive medicine.
Key Reasons:
- Increases implantation success rates
- Reduces miscarriage risk
- Enables single embryo transfer
- Improves live birth outcomes
Who Should Consider PGT?
Dr. Sweta Gupta recommends PGT for:
- Women above 35 years
- Couples with recurrent IVF failures
- History of multiple miscarriages
- Known genetic disorders
- Male factor infertility
- Couples opting for IVF with donor eggs/sperm
Step-by-Step PGT Procedure
1. Ovarian Stimulation
Hormones are administered to produce multiple eggs.
2. Egg Retrieval
Mature eggs are collected from ovaries.
3. Fertilization (IVF/ICSI)
Eggs are fertilized in a lab.
4. Embryo Culture
Embryos grow to blastocyst stage (Day 5/6).
5. Embryo Biopsy
Few cells are extracted safely.
6. Genetic Testing
Cells are analyzed using advanced techniques.
7. Embryo Freezing
Embryos are frozen while results are processed.
8. Transfer (FET Cycle)
Genetically normal embryo is transferred.
Advanced Technology Behind PGT
Modern PGT uses sophisticated genetic tools:
- Next-Generation Sequencing (NGS)
- Array CGH (Comparative Genomic Hybridization)
- PCR-based testing
These ensure highly accurate and reliable results.
Benefits of PGT in IVF
1. Higher Success Rates
Selecting healthy embryos increases implantation chances.
2. Reduced Miscarriage Risk
Genetic abnormalities are a major cause of miscarriage.
3. Healthy Baby Outcome
Minimizes risk of inherited disorders.
4. Single Embryo Transfer
Avoids multiple pregnancies.
5. Emotional Relief
Reduces uncertainty and stress.
PGT vs Traditional IVF: Key Differences
| Factor | Traditional IVF | IVF with PGT |
|---|---|---|
| Embryo Selection | Visual grading | Genetic testing |
| Success Rate | Moderate | Higher |
| Miscarriage Risk | Higher | Lower |
| Genetic Screening | No | Yes |
Is PGT Safe?
Yes, PGT is considered safe when performed by experienced embryologists.
- Biopsy does not harm embryo development
- High survival rate after freezing
- Widely used globally
Limitations of PGT
- Additional cost
- Requires advanced lab facilities
- Not 100% guarantee
- May not detect all genetic issues
Cost of PGT in Noida
The cost varies depending on:
- Type of PGT
- Number of embryos tested
- Clinic expertise
However, considering improved success rates, it is often a cost-effective long-term investment.
