Recurrent miscarriage can be a heartbreaking and emotionally draining experience for couples trying to conceive. Thankfully, advancements in reproductive genetics like Preimplantation Genetic Testing for Aneuploidy (PGT-A) are helping identify underlying causes and improve the success of IVF. At MotherToBe Fertility Centre, our experts use PGT-A as a powerful tool to support healthy pregnancies and reduce the risk of miscarriage, especially for those with repeated pregnancy loss.
What Is PGT-A, and How Does It Work?
PGT-A (Preimplantation Genetic Testing for Aneuploidy) is a diagnostic procedure performed on embryos during an IVF cycle to identify chromosomal abnormalities before embryo transfer. Here’s how it works:
- IVF and Embryo Development: Eggs are fertilized in the lab and cultured to the blastocyst stage (day 5–6).
- Embryo Biopsy: A few cells are carefully removed from the embryo’s outer layer (trophectoderm).
- Genetic Testing: The sampled cells are analyzed using advanced technologies like NGS (Next-Generation Sequencing) to detect any extra or missing chromosomes.
- Selection for Transfer: Only chromosomally normal (euploid) embryos are selected for uterine transfer, increasing the chance of a successful, healthy pregnancy.
Who Can Benefit Most from PGT-A?
PGT-A is not recommended for every IVF cycle but is particularly beneficial for certain groups of patients, including:
- Couples with Recurrent Miscarriage
Many miscarriages occur due to chromosomal abnormalities. PGT-A helps identify and avoid transferring abnormal embryos, thus reducing miscarriage risk. - Women Over Age 35
The risk of producing aneuploid embryos increases with age. PGT-A allows for better embryo selection in older women. - Previous Failed IVF Cycles
Couples with multiple failed IVF attempts may benefit from PGT-A to improve implantation chances. - Severe Male Factor Infertility
Genetic issues from sperm may lead to embryo abnormalities. PGT-A can screen out affected embryos. - Unexplained Infertility
For patients with no identifiable infertility cause, PGT-A can offer insights and improve outcomes.
What Does PGT-A Test For?
PGT-A primarily screens for aneuploidies, which are numerical chromosomal abnormalities. This includes:
- Trisomy (e.g., Down syndrome – Trisomy 21)
- Monosomy (e.g., Turner syndrome – Missing X chromosome)
- Complex chromosomal rearrangements
- Sex chromosome abnormalities (XXY, XYY, etc.)
By identifying these issues in embryos, MotherToBe Fertility Centre ensures only genetically healthy embryos are transferred, reducing the likelihood of miscarriage or genetic disorders.
Does PGT-A Affect Embryo Viability?
When performed by experienced embryologists using modern techniques, PGT-A is safe and does not harm embryo viability. In fact, studies have shown that embryos biopsied and frozen after PGT-A maintain high implantation and pregnancy success rates.
At MotherToBe, one of the best IVF centres in Hyderabad, we use advanced, minimally invasive embryo biopsy and vitrification methods to ensure maximum embryo survival and optimal outcomes.
Alternatives to PGT-A
While PGT-A can be a valuable tool, it’s not suitable or necessary for every couple. Alternatives and complementary options include:
- Comprehensive Chromosomal Screening (CCS)
- PGT-M (for single-gene disorders)
- Preconception Genetic Counseling
- Hysteroscopy or Endometrial Receptivity Testing
- Lifestyle and nutritional support to reduce oxidative stress and egg/sperm quality issues
A detailed fertility assessment at MotherToBe Fertility Centre will help determine whether PGT-A or another approach is best for your unique case.
Conclusion
If you or your partner are dealing with recurrent miscarriage, PGT-A might be the key to unlocking a successful and healthy pregnancy. At MotherToBe Fertility Centre, our goal is to empower couples with advanced fertility solutions, led by the best fertility specialists in Hyderabad and supported by cutting-edge laboratory technology.
FAQs About PGT-A and Miscarriage
Q1. Can PGT-A guarantee a successful pregnancy?
No, but it significantly increases the chance of implantation and reduces the risk of miscarriage by selecting chromosomally normal embryos.
Q2. Is PGT-A painful or risky for the woman?
No. The embryo biopsy is done in the lab; the woman undergoes the standard IVF process without any additional procedures.
Q3. Does PGT-A reduce the number of embryos available?
It may reduce the number of embryos considered viable, but those selected are more likely to lead to a successful pregnancy.
Q4. Is PGT-A worth the cost?
For couples with recurrent miscarriage or multiple IVF failures, the benefits of PGT-A in terms of time, emotional energy, and outcome success often outweigh the cost.
Q5. Where can I get PGT-A in Hyderabad?
MotherToBe Fertility Centre is one of the few clinics offering accurate PGT-A testing with expert embryologists and state-of-the-art equipment.
