A procedure that screens embryos for chromosomal abnormalities before implantation.
Chromosome testing examines embryos created through IVF or ICSI to confirm their genetic quality. Only embryos of sufficient quality are selected for transfer, meaningfully increasing the likelihood of a successful pregnancy.
PGT-A is most often paired with ICSI and a frozen embryo transfer for optimal results.
Gender selection & family balancing.
Complete chromosome information, including sex.
PGT-A screens all 24 chromosomes, which includes the X and Y sex chromosomes. So the same test that checks an embryo's chromosomal health also identifies its sex with high accuracy — information some couples use for family balancing.
Many international couples travel to Thailand for gender selection with IVF. During your consultation our specialists explain exactly how the process works, what PGT-A can and cannot tell you, and the guidelines that apply — with transparent, personalized pricing.
A precise, staged process.
Each step is performed by an experienced embryology and genetics team to safeguard embryo quality and result accuracy.
Obtain Embryos After Fertilisation
After IVF or ICSI, embryos are cultured in the laboratory until they reach the blastocyst stage — typically 5–6 days after fertilisation.
Embryo Cell Biopsy
A small number of cells from the part of the embryo that will develop into the placenta are gently removed for genetic testing.
Genetic Analysis (WGA)
Whole Genome Amplification increases the amount of genetic material available so it can be analysed for chromosomal abnormalities.
NGS Sequencing
Next Generation Sequencing reads the nucleotide sequences across all 24 chromosomes with high precision and accuracy.
Data Analysis
Results are interpreted by highly experienced specialists who focus exclusively on reproductive genetics.
Reporting Results
Clear, structured reports are returned within approximately 5–9 business days, ready to inform your transfer plan.

Common questions.
Is PGT-A safe for the embryo?
+
Yes. The biopsy is performed at the blastocyst stage on cells that will form the placenta, not the embryo itself, by experienced embryologists.
How accurate is PGT-A?
+
Our NGS-based screening offers an accuracy rate of greater than 98% across all 24 chromosomes.
How long does it take to get results?
+
Results are typically reported within 5–9 business days after the biopsy.
Does PGT-A guarantee pregnancy?
+
PGT-A significantly increases the chance of a successful, healthy pregnancy by selecting chromosomally normal embryos, but no fertility procedure can guarantee pregnancy.
Can PGT-A be combined with frozen embryo transfer?
+
Yes — PGT-A is most commonly paired with a frozen embryo transfer (FET) so screened, normal embryos can be transferred in an optimally prepared cycle.
Can PGT-A be used for gender selection or family balancing?
+
Yes. Because PGT-A screens all 24 chromosomes, including the X and Y sex chromosomes, it identifies each embryo's sex alongside its chromosomal health — which some couples use for family balancing. Our specialists talk you through the process and the applicable guidelines.
How much does gender selection with IVF cost in Thailand?
+
Gender selection is carried out through IVF/ICSI with PGT-A, so the cost depends on your overall treatment plan. Millennium IVF provides transparent, personalized pricing during your consultation.
