Quick answer
Yes, frozen embryos can be shipped internationally for surrogacy when three legal layers line up: written consent from everyone who controls the embryos, any export or import authorization the countries involved require, and a surrogacy plan that is lawful where the transfer happens. The clinics and an international embryo shipping provider then handle release, transport and customs.
Key takeaways
- No international treaty covers cross-border surrogacy or embryo transport. Each shipment follows the national (and sometimes state) rules at both ends.
- Embryos leave the clinic only when everyone with dispositional control, usually both intended parents, signs a release.
- Embryos made with donor eggs or sperm need donor-eligibility records; in the US these are set by FDA rules at 21 CFR Part 1271.
- Some destinations need an import authorization, and some require the surrogacy agreement or a court approval before embryo transfer.
- Most delays come from paperwork, not transport. Start the legal checklist before booking the shipment.
Important: this article is general information and is not legal advice. Laws differ by country and state and change over time. Confirm your situation with a licensed reproductive or surrogacy lawyer in each jurisdiction involved.
Can you transfer frozen embryos to another country?
In most cases, yes. Sending embryos abroad is a routine step in international surrogacy, but the law, not logistics, decides whether a specific shipment can go ahead. The sending clinic must be able to release the embryos, the receiving clinic must be allowed to accept them, and gestational surrogacy must be lawful where the embryo transfer takes place.
There is no global rulebook. The Hague Conference on Private International Law (HCCH) studied cross-border parentage and surrogacy for years, but in March 2026 its governing council decided not to proceed with drafting a convention at this stage and asked its Permanent Bureau to keep monitoring developments. For now, intended parents, clinics and couriers work with a patchwork of national rules.
If you are simply moving embryos between clinics without a surrogacy program, see our guide on how to move embryos from one clinic to another.
Who has the legal right to move the embryos?
Ownership vs. dispositional control
Clinics and courts rarely treat embryos as simple "property". What matters in practice is dispositional control: the right to decide whether embryos are stored, transferred, donated or discarded. It is defined by the consent and storage agreements signed when the embryos were created.
The American Society for Reproductive Medicine (ASRM) Ethics Committee states that programs must require people storing embryos to give written directives about their disposition, covering death, divorce or separation, unpaid storage fees and future disagreement. Those instructions can be changed at any time by new written instructions.
Consent from both partners
If a couple created the embryos, the originating clinic will normally require both people named in the storage agreement to sign a release or transfer authorization, often with notarized signatures and copies of photo ID. If the partners have separated and disagree, a clinic is unlikely to release embryos without both signatures or a court order. Check your original consent forms early: some limit where, or to whom, embryos may be released.
Donor eggs, donor sperm and donated embryos
In the US, reproductive cells and tissue are HCT/Ps (human cells, tissues and cellular and tissue-based products) under FDA rules at 21 CFR Part 1271:
- Partner embryos. Reproductive cells donated by a sexually intimate partner of the recipient are exempt from the donor-eligibility determination (§ 1271.90).
- Donor-derived embryos. Where a determination is required, the embryos must travel with a distinct identification code, a statement of donor eligibility and a summary of the records used (§ 1271.55).
- Redirected embryos. An embryo originally created for a couple and later intended for donation is permitted under § 1271.90, with the required labeling.
Destination countries may add their own rules. In the UK, for example, the donor of imported sperm, eggs or embryos must also have consented to storage. Programs built on donor eggs have extra steps, covered in our article on worldwide cryoshipping of eggs and embryos for surrogacy.
Legal documents checklist for an international embryo shipment
| Document | Issued or signed by | Why it matters |
|---|---|---|
| Embryo release / transfer authorization | All persons with dispositional control, on the clinic's form | The clinic cannot release embryos without it |
| Copy of the original consent and storage agreement | Originating clinic | Shows who controls the embryos and any conditions |
| Acceptance letter | Receiving clinic or lab | Confirms a licensed facility will receive and store the embryos |
| Embryology records (number, stage, freezing method, device labels) | Originating lab | The receiving lab must match every device and thaw correctly |
| Donor-eligibility records (donor gametes or embryos) | Egg or sperm bank, clinic | Required under 21 CFR 1271.55 in the US; others may ask for equivalents |
| Import / export authorization (where required) | Health authority or licensed clinic | Some jurisdictions accept or release embryos only with prior approval |
| Surrogacy agreement or court approval (where required) | Lawyers for each party; court | Some jurisdictions require it before any embryo transfer |
| Transport and customs documents, chain-of-custody record, temperature log | Cryo courier and both clinics | Customs clearance without opening the shipper; proof of handling |
Export and import rules by jurisdiction
United States
Under 21 CFR 1271.420, importers of HCT/Ps must notify FDA and hold the product until FDA makes an admissibility decision. That section does not apply to reproductive HCT/Ps donated by a sexually intimate partner of the recipient. In practice, embryos created from the intended parents' own eggs and sperm usually fall within this exception, while donor-derived embryos fall outside it.
Surrogacy is regulated by the states. California's Family Code section 7962, for example, requires separate independent lawyers for the surrogate and the intended parents, a notarized or witnessed agreement, and bars embryo transfer, or injectable medication in preparation for it, until the agreement is fully executed. The contract timeline and the shipping timeline must be planned together.
United Kingdom
According to the HFEA, imports and exports of eggs, sperm and embryos are arranged through a UK-licensed clinic, which checks that the overseas facility is licensed or accredited. If a move does not meet the standard requirements, the clinic can apply to the HFEA for special permission. Under HFEA General Direction 0006, embryos should not be exported if they could not lawfully be used in UK-licensed treatment in the way the receiving clinic proposes.
European Union
Regulation (EU) 2024/1938 on substances of human origin (SoHO) replaces the tissues and cells directive and explicitly covers sperm, oocytes and embryos. According to ESHRE's summary, most rules apply from 7 August 2027, and entities importing from outside the EU/EEA will need a specific authorization and written agreements with suppliers. Until then, national rules apply.
Other surrogacy destinations
Surrogacy laws by country differ widely: some countries allow only altruistic surrogacy, some require court or ethics committee approval before transfer, and some prohibit it. Because rules change, confirm three things with a local lawyer and the receiving clinic before you commit:
- Can the clinic legally accept imported embryos, and which documents does it need?
- Is gestational surrogacy lawful for your family situation?
- How will legal parentage be established there and recognized in your home country?
Surrogacy contracts, parentage and shipment timing
An embryo shipment plan cannot be separated from the surrogacy legal strategy:
- Involve lawyers in every jurisdiction: where the embryos are stored, where the surrogate lives, and the intended parents' home country. An experienced international surrogacy lawyer can coordinate the others.
- Confirm parentage recognition early. It can affect which records must travel with the embryos.
- Do not ship too early. Where a contract or court approval must precede transfer, shipping first only adds storage time and cost.
Intended fathers can also turn to Men Having Babies, a nonprofit offering surrogacy education, conferences and financial assistance to gay intended parents. ARK.CRYO is a partner and sponsored its New York 2025 conference.
Customs and air transport compliance
- A validated liquid nitrogen dry shipper, handled in line with IATA requirements (see how a dry shipper maintains −196°C).
- An accurate description of contents on customs documents, together with clinic paperwork, so the container is not opened.
- No X-ray screening of reproductive cells, agreed with carriers in advance.
- A continuous chain of custody and temperature log, so frozen embryo transport can be documented from lab to lab.
Common legal reasons embryo shipments are delayed
- One partner has not signed the release, or signatures were not notarized as required.
- The receiving clinic has not issued an acceptance letter or import approval.
- Donor-eligibility records are missing for donor-derived embryos.
- Names or embryo counts differ between consent forms, embryology report and transport documents.
- The surrogacy agreement or court approval required at the destination is not final.

FAQ
Can you transfer embryos to another country for surrogacy?
Yes, in most cases. The originating clinic must be able to release the embryos, the receiving clinic must be allowed to accept them, and surrogacy must be lawful for you at the destination. Everyone with dispositional control must sign, and any import or export authorization must be in place before a cryo courier moves the embryos in a dry shipper.
Do both partners need to consent to shipping embryos abroad?
Usually yes. Clinics release embryos according to the consent and storage agreement signed when the embryos were created. If two people share dispositional control, both typically must sign the release, often with notarized signatures. If partners disagree, clinics generally wait for a joint instruction or a court order.
Do I need an FDA import permit to bring frozen embryos into the US?
FDA does not issue a separate permit. Under 21 CFR 1271.420, importers of HCT/Ps must notify FDA and hold the product until FDA decides it is admissible. The rule does not apply to reproductive HCT/Ps from a sexually intimate partner of the recipient, so it mainly affects donor-derived embryos. Confirm specifics with the receiving clinic.
Are embryos created with donor eggs or sperm treated differently?
Yes. In the US, donor gametes and donor-derived embryos need a donor-eligibility determination under 21 CFR Part 1271, and the records summary, eligibility statement and identification code must accompany them. Destination countries may have their own rules on donor consent, anonymity or compensation, so check them before shipping.
Can embryos be shipped before the surrogacy contract is signed?
Sometimes, but it is often not advisable. Where the law requires a signed agreement or court approval before embryo transfer, as in California, the embryos cannot be used until that step is complete. Shipping early only adds storage time at the destination, so most intended parents align shipping with contract execution.
How much does it cost to ship embryos internationally?
Cost depends on the route and distance, the number of devices, customs and permit requirements at both ends, and the delivery timeline. Because each surrogacy route is different, shipments are quoted individually. See our pricing and delivery terms or request a quote.
Who handles customs paperwork for an embryo shipment?
The clinics provide the medical and consent documents; the cryo courier prepares transport and customs documents and coordinates clearance. ARK.CRYO offers 24/7 legal and customs support to help intended parents and clinics assemble a complete document set before the dry shipper leaves the lab.
