Is PGT Legal in Thailand for International Patients?

Is PGT Available in Thailand?

Preimplantation genetic testing (PGT) is available in Thailand for international patients when used for medical purposes. Some Thai fertility centers offer PGT for aneuploidy screening (PGT-A) and for single-gene disorders (PGT-M). The practice is guided by professional bodies and hospital ethics committees, which generally allow genetic testing of embryos to identify chromosomal abnormalities or inherited conditions before transfer.

However, the legal landscape for non-medical trait selection—such as choosing an embryo for physical characteristics like eye color or sex for non-medical reasons—is less clear. Regulations can vary and may be subject to change. International patients should always verify the current legal status and clinic policies directly with their chosen provider.

Important Distinctions

Medical vs. Non-Medical PGT

PGT for medical indications (e.g., avoiding a genetic disease, improving IVF success rates by selecting euploid embryos) is widely accepted and practiced in Thailand. PGT for non-medical traits may be restricted or prohibited. Always ask your clinic whether the specific testing you need is permitted under Thai law.

Regulatory Uncertainty

Thailand does not have a single, publicly codified law that explicitly lists all permitted and prohibited uses of PGT. Instead, medical practice is guided by professional bodies and hospital ethics committees. This means that policies can differ between clinics. Some centers may have more conservative or more permissive approaches.

What to Ask Your Clinic

Before proceeding, we recommend asking your clinic these questions in writing:

• Is PGT for my specific medical indication (e.g., PGT-A, PGT-M for a particular condition) currently offered to international patients?
• Are there any restrictions on the number of embryos tested or transferred?
• Do you offer PGT for sex selection or other non-medical traits? If so, what are the legal and ethical guidelines?
• What documentation or consent forms are required for international patients undergoing PGT?
• How do you handle embryos that are not transferred (e.g., disposal, donation, or research)?
