Overseas fertility treatment creates a specific and complex post-treatment situation that most patients do not anticipate at the booking stage: what happens to frozen embryos, eggs, or sperm held in another country? The contracts governing cryopreservation are among the most consequential documents a medical tourist will sign, and they are routinely signed without careful review.
What Cryopreservation Contracts Cover
A cryopreservation agreement is a contract between the patient and the clinic (or the clinic's storage facility) governing the storage of biological material. Standard terms include: the initial storage period covered by the treatment fee; the fee for ongoing annual storage beyond the initial period; conditions under which storage can be terminated by either party; the patient's obligations to maintain contact and confirm ongoing storage wishes; and what happens to stored material if the patient cannot be contacted for a defined period.
Less commonly addressed in the standard contract, but critically important to read: what happens to embryos on the death of one or both partners; the status of embryos in the event of separation or divorce; the conditions under which the clinic may use or destroy stored material; and the process for transferring material to another facility.
The Ongoing Storage Fee Problem
Many patients are surprised to find that annual storage fees for overseas clinics are not trivial. Depending on the country and clinic, annual cryopreservation fees range from a few hundred to over a thousand pounds per year. For patients who freeze embryos in their twenties with the intention of using them in their thirties, this amounts to a potentially significant ongoing cost billed by a foreign clinic in a foreign currency.
Check the contract for: the current annual fee, whether it is fixed or subject to annual increases, the payment method accepted (bank transfer, credit card), and what currency the fees are denominated in. Currency risk — the fee being denominated in Thai baht, Turkish lira, or another currency that fluctuates against sterling — can make future costs unpredictable.
What Happens If You Stop Paying
This is where the fine print matters most. Contracts almost universally specify that if a patient fails to pay storage fees and does not respond to contact attempts, the clinic may after a defined notice period either destroy the material or donate it to research. The notice period and the steps required before that outcome can occur vary significantly. Some contracts specify a notice period as short as 30 days from non-payment; others specify longer periods and require multiple contact attempts.
Understand this provision explicitly before signing. Ask the clinic: what is the process if I miss a payment? How many notices will I receive? What notice period applies before any irreversible action is taken?
Embryo Transport: The Logistics
Transporting cryopreserved embryos between countries is legally and logistically complex. It is not simply a matter of requesting a transfer — it involves regulatory compliance in both the exporting and importing country, certified transport by an approved carrier, and coordination between two clinical facilities with compatible storage protocols.
The key questions to establish before starting a transfer process:
What are the regulatory requirements in the country of storage for releasing biological material? Some countries require specific consents, government notifications, or licences for international transfer.
What are the import requirements in the receiving country? Many countries have specific regulations governing the import of human biological material, including requirements for documentation of donor screening, storage conditions, and chain of custody.
Is your receiving clinic in your home country equipped and willing to receive transferred embryos? Not all fertility clinics accept incoming transfers, and those that do have specific requirements for documentation and proof of storage conditions.
Who bears the cost and risk of transport? Embryo transport by an approved carrier uses specialised dry-shipper containers and typically costs between £500 and £2,000 per shipment, depending on distance. If material is damaged or lost in transit — an uncommon but possible outcome — the liability allocation in the contract determines what recourse you have.
Legal Status of Embryos in Different Jurisdictions
The legal status of frozen embryos differs significantly between countries. In some jurisdictions, embryos have no specific legal status separate from property; in others, they have a form of protected status. In the event of a dispute — between partners, with the clinic, or in the context of inheritance — the applicable law is that of the country where the embryos are stored, not the patient's home country.
For couples, this has particular implications in the event of relationship breakdown. Some countries' laws on consent to use of embryos after separation are more permissive than others; some require ongoing consent from both parties for any use. Understand the law of the country where your material is stored, not just the law of your home country.
Practical Steps Before Signing
Read the entire contract before signing, not just the summary provided by the clinic's patient coordinator. If the contract is not in your language, arrange a certified translation — see our guide on translating medical records at /guides/translating-medical-records for guidance on translation standards.
Ask the clinic specifically: what is the process for international transfer; what is the annual storage fee and when is it reviewed; what is the notice period before any irreversible action on unpaid storage; and what documentation will you receive confirming the storage arrangement.
Keep a copy of the signed contract, and keep the clinic's contact details permanently recorded. Patients who change email addresses or phone numbers and fail to update the clinic can find themselves unable to respond to notices sent to an old address — with the consequences described above.
