After a PGT IVF cycle in Thailand, you may have embryos that are not transferred immediately. You then face two linked decisions: where those embryos will be stored, and whether they will stay in Thailand or be shipped to another country. Storage and shipping are logistics questions, but they are also medical and legal ones. The safest approach is to treat every detail as something to confirm in writing with your treating clinic and, where relevant, with the receiving clinic and the authorities in both countries. This guide explains the categories you need to plan, the questions to ask, and the steps that usually sit on the critical path.
At a glance
- Embryo freezing and storage are usually arranged through the clinic that created the embryos, but the terms are clinic-specific.
- Cryostorage is normally time-limited and renewable; ask how renewal works and what happens if a payment is missed.
- Shipping embryos across borders involves the sending clinic, a receiving clinic, a transport provider and sometimes government authorities.
- No shipment should be booked until both clinics have confirmed they can receive, store and accept the embryos.
- Costs, documents and timelines vary by clinic and country, so treat any figure you see online as a prompt to ask, not a quote.
Why storage decisions matter after a PGT cycle
Preimplantation genetic testing (PGT) is often used to select embryos for transfer based on genetic information. Because a PGT cycle can produce more embryos than are transferred in one attempt, the remaining embryos may be frozen for future use. That creates a storage relationship with the clinic that lasts longer than the treatment cycle itself.
For international patients, this relationship has a practical complication: you may return home before you have decided what to do with the remaining embryos. The decisions you make before leaving Thailand — about consent, contact details, payment arrangements and who is authorised to act on your behalf — can shape how easy it is to manage storage later.
How embryo freezing and cryostorage usually work
Embryo freezing, also called cryopreservation, involves cooling embryos to very low temperatures so they can be stored for a period of time. The exact laboratory method, the storage conditions and the maximum storage period are determined by the clinic and by local rules. This guide cannot tell you what your clinic does; it can only tell you what to ask.
Storage is usually structured as an initial period followed by renewal. Some clinics include a short storage period in the cycle package; others charge separately. Renewal may be annual, or it may follow a different cycle. The important point is that storage is not automatically indefinite. It depends on the clinic’s terms, your instructions and, in some cases, local legal limits.
Questions to ask about freezing and storage terms
- How long is the initial storage period, and what happens at the end of it?
- How do I renew storage, and how will I be reminded?
- What happens if a renewal payment is late or missed?
- Can storage be transferred to another clinic in Thailand, and what would that involve?
- What are the clinic’s rules on consent, contact details and authorised representatives?
- What are the options if we decide not to continue storage?
Cryostorage fees: what the cost categories usually include
Storage fees are rarely a single number. They may include the freezing procedure itself, the initial storage period, renewal fees, administrative charges for changing instructions, and fees for preparing embryos for shipment. Because prices are clinic-specific and can change, this guide does not quote figures. Instead, use the categories below to build a complete picture before you commit.
| Cost category | What to confirm |
|---|---|
| Freezing procedure | Whether it is included in the cycle package or billed separately |
| Initial storage period | How long it covers and when it starts |
| Renewal fees | Frequency, amount, payment methods and grace periods |
| Administrative changes | Any charge for updating consent, contact details or instructions |
| Shipment preparation | Whether the clinic charges for documentation, packing or coordination |
| Transport and receiving clinic | Separate costs usually paid to the transport provider and the receiving clinic |
Ask for a written summary of what is included, what is optional and what is charged later. If you are comparing clinics, compare the same categories rather than headline prices.
Shipping embryos from Thailand: the moving parts
Cross-border embryo transport is a coordination problem. Several parties have to agree before anything moves:
- The sending clinic in Thailand must confirm it can release the embryos and prepare them for transport.
- The receiving clinic abroad must confirm it can accept, store and use embryos created elsewhere.
- A transport provider experienced in cryogenic shipment must be arranged.
- Documentation must satisfy the sending clinic, the receiving clinic and any relevant authorities.
- Timing must work for all parties, including customs and laboratory hours.
Each of these steps can fail or delay independently. That is why the practical rule is: do not book transport until both clinics have confirmed in writing that they are ready.
What the sending clinic may need to confirm
- That the embryos are eligible for release under the clinic’s own rules
- That consent from all relevant parties is documented
- That the clinic can prepare the embryos for shipment and hand them to a transport provider
- What notice period the clinic needs
- What documentation the clinic will provide
What the receiving clinic may need to confirm
- That it accepts embryos created in another country
- That it can store them and, if relevant, use them in treatment
- What records, test results or consent documents it requires
- Whether it has any restrictions related to PGT or the embryos’ history
- What its own storage terms and fees are
Legal and regulatory questions you should not assume
Rules about embryo storage, transport and use differ between countries. Some countries restrict what can be done with embryos created abroad, or require specific approvals before import. Others have limits on storage duration or on who can consent to future use.
This guide cannot tell you what is allowed in your situation. Instead, treat the following as questions for the relevant authority or a qualified professional in each country:
- Does the receiving country allow import of embryos created through PGT?
- Are there documentation, labelling or certification requirements for the shipment?
- Who is legally able to consent to storage, transport and future use?
- Are there limits on how long embryos can be stored, and what happens at the end of that period?
- What happens to the embryos if the receiving clinic closes or changes its services?
Because these answers can change, confirm them close to the time you plan to act rather than relying on older information.
A practical timeline for planning storage and shipping
The timeline below is a planning framework, not a schedule. Your clinic’s notice periods and the receiving country’s requirements will determine the actual dates.
- Before or during your Thai cycle: Ask how storage is handled, what the initial period covers and how renewal works.
- Before you leave Thailand: Confirm consent documents, contact details, payment arrangements and who can act on your behalf.
- After the cycle: Decide whether to keep storing in Thailand, transfer to another clinic in Thailand, or ship abroad.
- If shipping abroad: Confirm the receiving clinic will accept the embryos, then ask the sending clinic what it needs to release them.
- Arrange transport: Use a provider the clinics are willing to work with, and agree who is responsible at each stage.
- Confirm arrival: Ask the receiving clinic to confirm receipt and storage in writing.
- Set renewal reminders: Note storage renewal dates at both ends so nothing lapses.
Practical questions to ask your clinic
Bring these to your treating team, ideally in writing so you have a record:
- What are the storage terms, and how do I renew them?
- What happens if I lose contact or miss a renewal?
- Can I transfer storage to another clinic, and what would that involve?
- What do you need from me to prepare embryos for shipment?
- Which transport providers do you work with, and who coordinates the shipment?
- What documentation will you provide, and what do you need from the receiving clinic?
- What are the costs at each stage, and when are they payable?
Next-step checklist
- Request written storage terms, including renewal and end-of-storage options.
- Confirm consent and contact details before you leave Thailand.
- Identify a receiving clinic abroad and confirm it will accept your embryos.
- Ask both clinics what documentation and notice periods they require.
- Check the receiving country’s import rules with the relevant authority.
- Agree who is responsible for each stage of transport.
- Set reminders for storage renewal at both ends.

Frequently asked questions
Can I store embryos in Thailand after I return home?
Many clinics allow storage to continue after you leave, but the terms are clinic-specific. You will usually need to keep consent and contact details up to date, arrange payment, and understand what happens if a renewal is missed. Ask your clinic for its written storage terms before you travel home.
How long can embryos be stored?
Storage periods are set by the clinic and, in some cases, by local rules. There is no single answer that applies everywhere. Ask your clinic how long the initial period lasts, how renewal works, and whether there is a maximum storage limit in the relevant jurisdiction.
What is involved in shipping embryos from Thailand to another country?
Shipping usually requires a sending clinic willing to release the embryos, a receiving clinic willing to accept them, a transport provider experienced in cryogenic shipment, and documentation that satisfies both clinics and any relevant authorities. Because requirements differ by country, confirm the details with the clinics and the relevant authority before booking anything.
Do I need permission to import embryos into my home country?
Import rules vary. Some countries require specific approvals or documentation before embryos can enter. This is not something to assume either way. Check with the relevant authority in the receiving country, or with a qualified professional, before arranging transport.
What happens if I stop paying storage fees?
Clinics handle unpaid storage differently. Some provide a grace period and reminders; others have defined steps for embryos that are no longer covered by a storage agreement. Ask your clinic to explain its process in writing so you can plan accordingly.
