This guide is informational and educational only, and is not legal or medical advice. Requirements change and clinic policies differ, so confirm the details for your own transfer with your clinic and the receiving clinic in Spain.
Moving Embryos from the UK to Spain
Spain is one of the most established fertility destinations for UK patients, and moving embryos there is a route we handle often. What makes it different from many other corridors is that it sits on the other side of a genuinely new administrative layer — Brexit — which changed what has to happen before a UK-created embryo can leave the country for an EU clinic. The rest of the process, clinic to clinic, follows the same clear path we use everywhere.
The Post-Brexit Export Licence
UK-created embryos exported to an EU clinic, including one in Spain, now require an HFEA export licence — a process that typically takes several weeks. We coordinate closely with your clinic's regulatory team throughout, but it's strongly recommended to start this conversation early rather than a few weeks before your treatment date.
This licence sits alongside the export and import paperwork that any international transfer needs, not in place of it. Your UK clinic applies for the licence naming Embryo Links as the courier, and the receiving Spanish clinic confirms it separately with its own agreement to accept the material.
Before your UK clinic can apply for the export licence, they need to check your original storage consent forms. If those consents are out of date, incorrectly signed, or missing, the clinic is legally required to refuse to release the tissue. It's worth asking your clinic to verify your consents before the export process is launched, so this doesn't become the thing that holds up your timeline.
The Documents You Need
Beyond the HFEA export licence, the sending clinic prepares an agreement confirming Embryo Links is acting on your behalf, and the receiving clinic in Spain provides its own agreement to accept the material. No X-ray letters are arranged for both airports so the tank is inspected by hand, and a customs release letter is prepared so it can be cleared on arrival in Spain. We coordinate the full pack with both clinics so nothing is left for you to chase.
Airline Approval
The cryogenic tank travels as cabin baggage with the courier at all times. It is never checked in or sent as cargo, which keeps it under the courier's eye and off the hold's X-ray screening throughout. Written approval for the tank as cabin baggage is arranged directly with the carrier's cargo or dangerous goods division ahead of the flight.
The Journey, Step by Step
- A qualified courier collects your embryos in a cryogenic tank holding minus 196 degrees. The embryologist verifies them against your records before loading.
- At the airport, the courier presents the prepared documentation so the tank is inspected by hand rather than passed through a scanner.
- The courier carries the tank in the cabin throughout the flight to Spain, never in cargo.
- On arrival, the receiving clinic clears the tank using the customs documentation prepared in advance.
- The embryologist verifies the embryos and vessel before storage. You are kept updated throughout, from collection to confirmed receipt.
How Long It Takes
Plan for several weeks, mainly to allow time for the HFEA export licence rather than the transport itself, which is quick once the paperwork is in place. Starting early, before your treatment dates are fixed, lets the documentation be completed without pressure on either side.
Frequently Asked Questions
Can frozen embryos be transported to Spain from the UK?
Yes, with the right documentation: an HFEA export licence, an import agreement from the receiving clinic, customs release for the destination airport, and airline approval for the tank as cabin baggage.
Does Brexit affect embryo transport to Spain?
Yes. UK-created embryos now need an HFEA export licence before leaving for an EU clinic, which takes several weeks to arrange and sits alongside the usual clinic-to-clinic paperwork.
Will the embryos be safe on the journey?
Yes. They travel in a cryogenic tank holding minus 196 degrees for far longer than the journey, carried in the cabin by a qualified courier who stays with it the entire way. The receiving clinic verifies them on arrival.
How long should I allow?
Several weeks, mainly for the export licence. Begin before your treatment dates are fixed so the paperwork isn't rushed.
