PGT-A in Thailand for Women Under 35: What to Consider

What Is PGT-A and How Does It Relate to Women Under 35 in Thailand?

PGT-A (preimplantation genetic testing for aneuploidy) screens embryos for chromosomal abnormalities before transfer. For women under 35, the chance that a biopsied embryo is chromosomally normal (euploid) is generally higher than for older women. However, exact rates vary by individual and clinic. No specific euploidy rates for women under 35 in Thailand are available from approved sources. It is important to discuss your personal situation with your clinic.

PGT-A helps select which embryos to transfer first, but it does not guarantee pregnancy. Success depends on many factors including embryo quality, uterine health, and the transfer process.

General Euploidy Trends by Age

While exact rates differ between clinics and patient populations, published data show a clear decline in euploidy with advancing maternal age. For women under 35, the majority of embryos are expected to be euploid. However, no specific rates for Thai clinics are provided in approved sources. Your personal rate depends on ovarian reserve, response to stimulation, and embryo development. No clinic can guarantee a specific number of euploid embryos.

Key Uncertainties and Limitations

PGT-A is a screening test, not a diagnostic test. It involves removing a few cells from the trophectoderm (future placenta) of a blastocyst-stage embryo. Limitations include:

• Mosaicism: Some embryos have both normal and abnormal cells, which can lead to inconclusive results.
• Embryo biopsy risk: Although rare, biopsy may damage the embryo.
• No test for all conditions: PGT-A only screens for chromosome number abnormalities, not single-gene disorders or structural rearrangements.
• False positives/negatives: A small chance that a euploid embryo is actually abnormal, or vice versa.

Success also depends on the transfer of a single euploid embryo. Pregnancy and live birth rates per transfer are generally high for women under 35, but no outcome can be guaranteed.

Questions to Ask Clinics in Thailand

When considering PGT-A at a Thai fertility center, ask these questions directly:

• What is your laboratory’s euploidy rate for women under 35 in the last year? (Note: This data may not be publicly available; ask if they can provide it.)
• Do you use next-generation sequencing (NGS) for PGT-A? What is your reporting turnaround time?
• How do you handle mosaic embryos? Do you offer re-biopsy or additional testing?
• What is your embryo survival rate after biopsy and vitrification?
• What is your ongoing pregnancy rate per single euploid embryo transfer for women under 35?
• Are your embryologists certified by ESHRE or similar bodies?
• What is included in the PGT-A package? Are there additional costs for biopsy, freezing, or shipping?

Confirm current requirements and outcomes directly with the treating clinic.

Frequently asked questions

What is a good euploidy rate for PGT-A in women under 35?

Euploidy rates vary by individual and clinic. For women under 35, the majority of embryos are expected to be euploid, but no specific rate is guaranteed. Discuss your personal chances with your doctor.

Does PGT-A guarantee a successful pregnancy?

No. PGT-A helps select chromosomally normal embryos, which may reduce miscarriage risk, but pregnancy depends on many factors including uterine health, embryo quality, and implantation.

How long does PGT-A take in Thailand?

PGT-A results typically take 7–14 days after biopsy, depending on the laboratory and shipping logistics. Confirm turnaround time with your clinic.

Is PGT-A recommended for all women under 35?

PGT-A is often considered for women under 35 with recurrent miscarriage, previous aneuploidy, or severe male factor infertility. For others, the benefit may be smaller. Discuss with your doctor.
