In Thailand, preimplantation genetic testing (PGT) can reveal an embryo's sex, but using it for non-medical sex selection is restricted by law. This article explains the legal and ethical landscape, what PGT can and cannot do, and questions to ask your clinic.
Can you choose the sex of your baby with PGT in Thailand?
The short answer is: No, not for non-medical reasons. In Thailand, the use of preimplantation genetic testing (PGT) to select an embryo’s sex for family balancing or personal preference is not permitted by law. However, PGT can reveal the sex of embryos as part of medical testing, and in very limited medical circumstances, sex selection may be allowed to prevent serious sex-linked genetic disorders. This article explains the legal framework, ethical considerations, and what you need to know if you are considering PGT in Thailand.
What does Thai law say about sex selection?
Thailand’s Medical Council regulations and the Protection of the Embryo and Fetus for Medical Research Act (unofficial translation) prohibit the use of assisted reproductive technology (ART) for sex selection unless there is a clear medical indication. The law aims to prevent gender discrimination and uphold ethical standards in reproductive medicine. While the exact wording may vary, the consensus among Thai fertility specialists is that non-medical sex selection is not allowed.
This means that even if PGT can determine whether an embryo is XX (female) or XY (male), the clinic cannot use that information to choose which embryo to transfer based on sex alone. The decision to transfer embryos must be based on medical criteria, such as chromosomal normality or absence of a specific genetic disease.
What is PGT and how does it relate to sex?
Preimplantation genetic testing (PGT) is a technique used during IVF to screen embryos for genetic abnormalities before transfer. There are different types:
- PGT-A (aneuploidy screening): Checks for extra or missing chromosomes, which includes the sex chromosomes (X and Y). This test can reveal the sex of the embryo as a byproduct.
- PGT-M (monogenic disorders): Tests for specific single-gene diseases, such as cystic fibrosis or thalassemia. If the disease is sex-linked (e.g., Duchenne muscular dystrophy), the test may also identify the sex.
- PGT-SR (structural rearrangements): Detects chromosomal rearrangements like translocations, which may also involve sex chromosomes.
In all cases, the primary purpose is medical. The sex information is incidental, and clinics are legally bound not to use it for selection unless medically justified.
When might sex selection be medically allowed?
There are rare medical scenarios where selecting an embryo’s sex may be permitted:
- Prevention of sex-linked genetic disorders: For example, if a mother carries a mutation for hemophilia (which primarily affects males), the clinic may select female embryos to avoid the disease.
- Severe congenital conditions affecting one sex: In some cases, a condition may be so severe that it is considered a medical reason to select against that sex.
These exceptions require approval from the clinic’s ethics committee and possibly the Thai Medical Council. The decision is made on a case-by-case basis, and the couple must provide medical documentation.
Ethical considerations
The ban on non-medical sex selection reflects broader ethical concerns:
- Gender equality: Allowing sex selection could reinforce gender stereotypes and lead to imbalanced sex ratios.
- Embryo status: Selecting embryos based on sex treats them as commodities rather than potential life.
- Social impact: In some cultures, preference for one sex (often male) can lead to discrimination and demographic imbalances.
Thailand’s approach aligns with many countries, including the UK, Australia, and most of Europe, where non-medical sex selection is prohibited. However, it differs from countries like the United States, where sex selection is generally allowed.
What if you want to know the sex for family balancing?
Family balancing—the desire to have a child of a particular sex to achieve a more balanced family—is not considered a medical indication in Thailand. Therefore, it is not a legal basis for sex selection. Some patients may consider traveling to other countries where it is permitted, but that involves different legal and ethical frameworks.
Questions to ask your clinic
If you are considering PGT in Thailand and are curious about sex selection, here are important questions to discuss with your fertility clinic:
- Does your clinic offer PGT-A, PGT-M, or PGT-SR? What are the medical indications?
- Under what circumstances, if any, does your clinic allow sex selection?
- What is the process for obtaining ethics committee approval for medical sex selection?
- Can you tell me the sex of my embryos as part of PGT results? (Note: Some clinics may disclose this information, but they cannot use it for selection.)
- What are the legal consequences if a clinic is found to be performing non-medical sex selection?
It is also wise to consult with a legal expert familiar with Thai reproductive law, as regulations can change.
Alternatives and considerations
If sex selection is important to you, you may want to explore options in other countries where it is legal. However, be aware of the ethical, legal, and medical implications. Always verify the credentials of any clinic and ensure they follow local laws.
For patients in Thailand, the focus should remain on the medical benefits of PGT: reducing the risk of genetic disorders and improving the chances of a healthy pregnancy. The sex of the baby is a secondary consideration that, by law, cannot be the primary reason for embryo selection.
Summary
- Non-medical sex selection using PGT is illegal in Thailand.
- PGT can reveal embryo sex as a byproduct, but this information cannot be used for selection.
- Medical exceptions exist for preventing serious sex-linked genetic diseases, subject to ethics approval.
- Always confirm current regulations with your clinic and legal advisor.

Frequently asked questions
Is it legal to choose the sex of my baby with PGT in Thailand?
No, it is not legal for non-medical reasons. Thai law prohibits using PGT for sex selection unless there is a medical indication, such as preventing a serious sex-linked genetic disorder.
Can PGT tell me the sex of my embryos?
Yes, PGT-A and other forms of PGT can reveal the sex chromosomes, so the sex of each embryo can be known. However, clinics are not allowed to use this information to select embryos for transfer based on sex alone.
What are the medical exceptions for sex selection in Thailand?
Sex selection may be permitted to avoid passing on a severe sex-linked genetic disease (e.g., hemophilia, Duchenne muscular dystrophy). This requires approval from the clinic's ethics committee and possibly the Thai Medical Council.
Can I go to Thailand for IVF and then have sex selection in another country?
That would involve separate legal and medical processes. You would need to comply with the laws of both countries. It is important to consult with legal experts and clinics in each jurisdiction.
What should I ask my clinic about sex selection?
Ask whether they offer PGT, under what conditions they disclose embryo sex, and whether they have ever obtained ethics approval for medical sex selection. Also inquire about the legal framework they operate under.
