You’ve likely heard about IVF, but have you explored the advanced technologies that can significantly improve its success? One of the most powerful tools in modern fertility treatment is Preimplantation Genetic Testing (PGT).
Think of PGT as a way to gain deeper insight into the health of your embryos before a transfer. At Genesis IVF, we utilise this technology to help couples in Malaysia make more informed decisions and increase their chance of a successful, healthy pregnancy.
What is PGT, Really? A Simple Explanation
During an IVF cycle, multiple embryos may be created. Not all embryos are chromosomally healthy. In fact, chromosomal abnormalities are a leading cause of implantation failure and miscarriage.
PGT is a sophisticated technique that allows us to screen embryos for these chromosomal abnormalities before they are transferred to the womb. A few cells are gently biopsied from the outer layer of a 5-day-old embryo (a blastocyst), which later becomes the placenta. These cells are then sent to a specialised genetics lab for analysis, while the embryo is safely frozen.
The Different Types of PGT: Which One is Right for You?
PGT isn’t a one-size-fits-all test. There are different types designed for specific situations:
- PGT-A (Aneuploidy Screening):
- What it checks for: The correct number of chromosomes. A healthy embryo should have 46 chromosomes. PGT-A identifies embryos with extra or missing chromosomes (like Down syndrome – Trisomy 21).
- Who it’s for: This is the most common type of PGT. It’s especially beneficial for women over 35, couples with recurrent miscarriage, or those with multiple failed IVF cycles.
- PGT-M (Monogenic/Single Gene Disorders):
- What it checks for: Specific inherited genetic conditions caused by a single gene, such as Thalassaemia, Cystic Fibrosis, or Huntington’s disease.
- Who it’s for: Couples who are known carriers of a specific genetic disorder and want to avoid passing it on to their children.
- PGT-SR (Structural Rearrangements):
- What it checks for: Unbalanced chromosomal rearrangements, such as translocations.
- Who it’s for: Patients where one partner has a balanced chromosomal rearrangement, which can lead to recurrent pregnancy loss.
How PGT Can Increase Your IVF Success Rates
Integrating PGT into your IVF journey offers several powerful advantages:
- Higher Implantation Rate: By selecting a chromosomally normal (euploid) embryo for transfer, the likelihood of it successfully implanting in the uterine lining is significantly increased.
- Reduced Risk of Miscarriage: Since most first-trimester miscarriages are due to chromosomal abnormalities, transferring a tested embryo dramatically lowers this heartbreaking risk.
- Shorter Time to Pregnancy: PGT helps avoid transferring embryos that have little chance of success. This can prevent multiple failed cycles and get you to a successful pregnancy faster.
- Informed Family Planning: For patients using PGT-M, it provides the peace of mind of knowing you have significantly reduced the risk of passing on a known genetic condition.
- Single Embryo Transfer (SET): With the confidence of knowing an embryo is chromosomally healthy, your doctor can recommend transferring a single embryo. This drastically reduces the risks associated with multiple pregnancies (twins, triplets) for both the mother and babies.
Is PGT Right for You?
While powerful, PGT is not necessary for every IVF patient. You and your doctor at Genesis IVF might consider PGT if you:
- Are a woman aged 35 or older.
- Have a history of two or more miscarriages.
- Have experienced multiple failed IVF cycles.
- Are a known carrier of a genetic disorder (or have a family history of one).
- Have severe male factor infertility.
- Want to pursue the most efficient path to a single, healthy baby.
Your Journey, Informed by Science
PGT represents a significant step forward in personalised reproductive medicine. It empowers you and your doctor with valuable information, turning guesswork into a strategic plan.
At Genesis IVF Malaysia, we are committed to providing access to these advanced technologies. Our goal is not just to help you achieve a pregnancy, but to support you on the journey to a healthy baby.
