Question 1

Who should consider PGT-A genetic testing?

Accepted Answer

Patients over 35, those with recurrent miscarriages, or couples with multiple failed IVF cycles should consider PGT-A. This screening identifies embryos with 46 chromosomes to improve implantation success. Leading Thai specialists like Dr. Teraporn Vutyavanich use day 5 blastocyst biopsies to prioritize healthy embryos for transfer.

Advanced maternal age: Recommended for women 35+ due to 50–70% chromosomal abnormality rates.
Recurrent pregnancy loss: Essential for patients with 2 or more miscarriages to find viable embryos.
Previous aneuploidy: Advised for those with prior pregnancies affected by conditions like Down syndrome.
Single embryo transfer: Ideal for patients wanting to maximize success while avoiding multiple births.

Bookimed Expert Insight: Thailand is a global hub for genomic expertise, featuring specialists like Dr. Wasin Naknam who hold European Society of Human Reproduction and Embryology (ESHRE) certifications. While US clinics often charge per embryo, Thai facilities like Gift Fertility Clinic frequently offer bundled testing for up to 8 embryos. This approach provides better statistical odds for finding a healthy embryo in a single cycle.

Patient Consensus: Patients emphasize that while testing adds to the timeline, it significantly reduces the emotional toll of failed transfers. Many suggest discussing mosaic embryo findings carefully before making final disposal decisions.

Question 2

How accurate is the PGT-A genetic test in Thai clinics?

Accepted Answer

Genetic testing for aneuploidy (PGT-A) in Thai clinics reaches 97% to 99.9% accuracy using Next-Generation Sequencing (NGS) technology and Illumina platforms. This gold-standard approach screens all 24 chromosomes to identify healthy embryos, significantly increasing clinical pregnancy rates to 60–75% for patients under 35.

Screening technology: Clinics utilize Next-Generation Sequencing (NGS) for high-resolution chromosomal analysis.
Gender identification: Thai labs identify embryo sex with 99.9% accuracy for family balancing.
Success impact: PGT-A improves pregnancy rates by 10–20% compared to untested embryo transfers.
Clinical reliability: Research indicates a misdiagnosis rate of less than 1% after transfer.

Bookimed Expert Insight: Thai specialists like Professor Teraporn Vutyavanich are uniquely qualified with ESHRE senior embryologist certifications. This level of laboratory expertise is rare. It ensures that the delicate biopsy of 5–10 cells from the trophectoderm won't compromise embryo viability. High-volume centers in Bangkok maintain accuracy levels identical to top-tier US clinics using the same Illumina technology.

Patient Consensus: Patients value how PGT-A reduces miscarriage risks to under 5%. Some advise checking clinic policies on mosaic embryos, as conservative labs may discard potentially viable segments.

Question 3

Does embryo biopsy for PGT-A damage the embryos?

Accepted Answer

Embryo biopsy for PGT-A typically does not damage embryos when performed by skilled embryologists. The procedure carries a low risk of accidental damage, estimated at less than 1-2%. Targeted cells are removed only from the outer layer, leaving the future fetus untouched.

Targeted sampling: Surgeons remove 5–10 cells from the trophectoderm, preserving the inner cell mass.
Cell regeneration: Remaining cells in the 100-cell blastocyst divide rapidly to replenish the sampled area.
Experience factor: Safety depends on lab expertise, including ESHRE-certified senior embryologists like Dr. Teraporn Vutyavanich.
Non-invasive options: Some Thai clinics offer DNA-free media analysis to eliminate physical biopsy risks entirely.

Bookimed Expert Insight: While many focus on physical damage, the real differentiator in Thai clinics is the success of the subsequent freeze-thaw cycle. Data shows that even a perfect biopsy matters little if the lab lacks high-tech vitrification facilities, as weak embryos are more vulnerable during cooling than during the actual cell sampling.

Patient Consensus: Patients often report that the emotional stress of waiting two weeks for genetic results exceeds the physical risks of the biopsy itself. Many suggest having a backup plan, as testing eight embryos does not guarantee any chromosomal normalcy.

Question 4

How long does it take to receive PGT-A results?

Accepted Answer

Receiving PGT-A results in Thailand typically takes 7 to 14 days once the laboratory receives embryo biopsies. The total timeline from egg retrieval often spans 2 to 3 weeks. This includes 5 to 7 days for embryos to reach the blastocyst stage before testing begins.

Laboratory processing: Most Thai genetics labs complete chromosomal analysis within 7 to 10 days.
Shipping logistics: International lab transfers from Bangkok can add 2 to 3 days to timelines.
Clinic batching: Some facilities group biopsies from multiple patients, potentially delaying start dates by several days.
Administrative steps: Results release requires confirmed payments and signed consent forms from both partners.

Bookimed Expert Insight: Thai fertility specialists like Prof. Dr. Teraporn Vutyavanich often utilize high-tech local labs to bypass international shipping delays. Choosing a clinic with an on-site laboratory in Bangkok can shave 3 days off your wait time. This efficiency allows for faster planning of the frozen embryo transfer cycle.

Patient Consensus: Many patients find that digital portals updated by the clinic provide results faster than formal reports. Expect a total wait of 18 to 21 days if biopsies coincide with major public holidays.

Question 5

Does PGT-A provide information about embryo gender?

Accepted Answer

PGT-A analysis identifies embryo biological sex with over 98% accuracy by examining all 23 chromosome pairs. While primarily used to screen for chromosomal abnormalities like Down syndrome, the process inherently detects X and Y chromosomes. This allows specialists in Thailand to verify embryo gender before implantation.

Chromosomal screening: PGT-A evaluates XX (female) and XY (male) pairs alongside 22 autosomes.
Medical necessity: Testing identifies sex-linked conditions like Hemophilia or Duchenne muscular dystrophy.
Family balancing: Parents may use results to choose a specific sex for sibling variety.
Masking options: Patients can often opt out of seeing gender data on specific reports.

Bookimed Expert Insight: Thai clinics like Gift Fertility Clinic utilize high-tech labs where PGT-A is often bundled into IVF packages. Data shows that world-class experts like Prof. Dr. Teraporn Vutyavanich perform these biopsies on day 5-7 blastocysts. This timing ensures higher cell counts for more reliable gender and aneuploidy results compared to earlier testing.

Patient Consensus: Reports for up to 8 embryos typically show exact counts, such as three normal girls and one normal boy. Most patients find that gender results are automatically included in the full genetic health breakdown.
