Advancements in reproductive technology have significantly improved the chances of successful pregnancies, especially through techniques like Preimplantation Genetic Testing (PGT). Thailand’s fertility clinics have increasingly adopted PGT as part of IVF treatment, helping individuals and couples reduce the risk of genetic disorders and improve overall IVF success rates.
But what exactly is PGT, and how do Fertility Treatment Clinics In Thailand apply it? This blog explores the process, benefits, and considerations of PGT in Thailand, especially for international patients considering treatment abroad.
What is PGT
Preimplantation Genetic Testing (PGT) is a technique used during IVF to screen embryos for genetic abnormalities before they are implanted in the uterus. It helps identify embryos with the correct number of chromosomes (euploid) and detect inherited genetic diseases.
There are three main types of PGT:
- PGT-A (for Aneuploidies): Checks for chromosome imbalances, such as Down syndrome or Turner syndrome.
- PGT-M (for Monogenic Disorders): Screens for specific inherited diseases like cystic fibrosis or sickle cell anemia.
- PGT-SR (for Structural Rearrangements): Detects chromosomal structural changes such as translocations.
How Thai Fertility Clinics Use PGT
Thailand is home to several well-equipped IVF centers offering PGT in conjunction with advanced embryology labs and experienced genetic counselors. Here’s how PGT typically fits into the IVF journey:
- Ovarian Stimulation and Egg Retrieval
Eggs are collected from the intended parent or donor after stimulation. - Fertilization and Embryo Culture
Fertilized eggs (embryos) are cultured in the lab for 5–6 days to reach the blastocyst stage. - Embryo Biopsy and Freezing
A few cells are carefully biopsied from each embryo. The embryos are then frozen while the cells are sent for genetic analysis. - Genetic Screening Results
Results indicate which embryos are genetically normal and suitable for transfer. - Embryo Transfer
A genetically healthy embryo is thawed and transferred to the uterus.
Who Should Consider PGT?
PGT is not necessary for all IVF patients, but it can be particularly helpful for:
- Women over age 35 (higher risk of chromosomal issues)
- Couples with a history of genetic diseases
- Recurrent IVF failure or pregnancy loss
- Male factor infertility with abnormal sperm DNA
- Carriers of chromosomal translocations
PGT improves the chance of implantation, reduces the likelihood of miscarriage, and helps avoid transferring embryos with serious genetic abnormalities.
What Makes Thailand an Attractive Option for PGT?
- Modern Technology and Trained Specialists
Clinics in Thailand use up-to-date technology, often comparable to top Western facilities. Many embryologists and fertility doctors are internationally trained and stay current with the latest protocols. - Affordability
While PGT is an added cost on top of IVF, the total treatment cost in Thailand is often more affordable than in countries like the U.S., Australia, or the U.K., making it appealing for medical tourists. - English-Speaking Staff and Patient Coordination
Top fertility centers in Thailand have multilingual staff and dedicated coordinators to help international patients navigate their treatment smoothly. - Regulation and Ethics
Thailand maintains strict regulations around embryo handling and genetic screening, ensuring that clinics follow internationally accepted ethical standards.
Moving Forward with Knowledge and Care
PGT is a powerful tool in modern fertility care, offering insight and assurance to patients with complex reproductive needs. Thailand’s fertility clinics combine technical excellence with compassionate care, making them a viable choice for those considering PGT as part of their IVF journey.
Thinking About Genetic Screening in Thailand?
- Ask clinics whether they offer PGT-A, PGT-M, or PGT-SR
- Request to speak with a genetic counselor before treatment
- Understand the additional costs and timelines involved
- Verify clinic accreditations and success rates with PGT
With the right information and a supportive medical team, PGT can bring clarity and confidence to your fertility journey.
