IVF Genetic Testing (PGT) in Bangkok, Thailand

Why Bangkok is the primary destination for PGT in Thailand

Bangkok accounts for the majority of PGT cycles performed in Thailand. The city's fertility centers have invested in dedicated molecular genetics divisions staffed by embryologists and geneticists who work on-site rather than relying on external reference labs. This matters for turnaround time and for complex cases like PGT-M that require direct coordination between the genetics team and the IVF cycle schedule.

PGT-SR, used for patients who carry chromosomal rearrangements such as translocations, is offered at a smaller number of Bangkok centers. If this is your situation, confirm during initial consultation whether the clinic has handled your specific type of rearrangement and ask about their lab's reporting process.

PGT-M in Bangkok: custom probe requirements

PGT-M is used to screen for single-gene disorders such as thalassemia, BRCA-linked conditions, cystic fibrosis, and spinal muscular atrophy. It requires a custom probe or linkage analysis designed specifically for your mutation before the IVF cycle can begin. This design phase takes four to six weeks and must be completed before stimulation starts.

Bangkok genetics teams see a high volume of thalassemia cases given regional prevalence. For conditions less common in Southeast Asia, verify the lab has managed your specific mutation or a closely related variant. Not all centers offering PGT-A also have the infrastructure for PGT-M probe preparation.

PGT-A in Bangkok: results timing and what to expect

PGT-A screens all embryos that reach blastocyst stage for chromosomal count abnormalities. Each embryo is biopsied on day five or day six. Biopsy samples are sent to the genetics lab and results are typically returned within seven to ten days for fresh cycles; some Bangkok clinics complete analysis within five days.

Results classify each embryo as euploid (normal chromosome count), aneuploid (abnormal), or mosaic (mixed cell lines). Mosaic embryos may still be transferred in certain clinical situations; ask your clinic for their written policy on mosaic transfers before your cycle begins, as practice varies between centers.

Gender selection through PGT-A in Bangkok

PGT-A reports sex chromosomes as part of the standard results. Under the Thai ART Act B.E. 2558 (2015), sex selection for non-medical reasons is prohibited. Elective gender selection or family balancing based on PGT-A findings is not a lawful indication for treatment in Bangkok or anywhere in Thailand.

PGT-A is permitted for medical indications: chromosomal screening, advanced maternal age, recurrent pregnancy loss, and prior IVF failure. If a clinic presents gender selection as an available add-on, that is outside the legal framework.

Two trips for PGT in Bangkok

PGT cycles in Bangkok follow a two-visit structure for most international patients. The first trip covers the stimulation monitoring and egg retrieval. Stimulation can be monitored remotely at a clinic near your home; you travel to Bangkok only for the retrieval, which is typically an eight to ten day stay depending on your response.

After retrieval, embryos are cultured, biopsied, and vitrified. Genetics results come back while you are home. The second trip for the embryo transfer is shorter, typically four to five days. The two visits are usually separated by one to two months, though timing depends on your uterine preparation protocol and test results.

Embryo storage and the export restriction in Bangkok

Thai law prohibits the export of frozen eggs and embryos. Embryos created during your Bangkok cycle cannot be transported to another country or to a clinic in a different Thai city. All embryos must be stored and transferred at the clinic where they were created.

Storage fees apply from the point of vitrification. Confirm the clinic's annual storage cost and what happens to stored embryos if you do not return within a specified period. If your Bangkok clinic closes or you need to change providers, embryos cannot move to a new Thai facility under current law.

PGT in Bangkok: common questions

Does PGT in Bangkok require legal marriage?

Yes. The Thai ART Act B.E. 2558 (2015) restricts ART treatment, including PGT cycles, to legally married heterosexual couples. Unmarried couples and single individuals are not eligible for IVF or PGT at licensed clinics in Bangkok.

Do I need to stay in Bangkok for the full treatment?

No. Ovarian stimulation can be monitored at a clinic near you. You travel to Bangkok for the egg retrieval and again for the embryo transfer, with a gap of one to two months between visits.

How long does IVF with PGT take in Bangkok?

Two trips. The retrieval stay is typically eight to ten days. The transfer visit is four to five days. PGT-M cases require an additional four to six weeks of probe preparation before the retrieval cycle can begin.

Can I take my frozen embryos out of Bangkok after treatment?

No. Thai law prohibits the export of frozen eggs and embryos. Embryos created in Bangkok must be transferred or stored in Thailand, with no exceptions.

What if no embryos pass PGT in Bangkok?

Your clinic will review the stimulation protocol and discuss next steps, which may include a second retrieval cycle. This outcome is more common in women over 40, where chromosomal abnormality rates rise significantly with age. Knowing before transfer is far more useful than an unexplained implantation failure.

Is Bangkok a good option for PGT-M?

Yes, particularly for conditions more prevalent in Southeast Asia such as thalassemia. Bangkok genetics teams manage a high volume of these cases and are experienced with the custom probe preparation process. For rarer conditions, ask your clinic directly whether they have handled your specific mutation before committing to treatment.
