Frozen embryos can be moved from the UK or Europe to a clinic in Bangladesh, and the journey itself is the straightforward part. The material travels at −196°C in a vapour-phase dry shipper that holds temperature for up to 21 days, hand-carried in the aircraft cabin by one courier who never hands it to anyone else. What sets the timeline is paperwork, not flying time. Both clinics have to agree in writing, the sending clinic has its own authorisation to complete, and a long routing with a connection needs every transit point covered before anyone books a seat.
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 Bangladesh.
The Bangladesh Route
Moving your frozen embryos to a clinic in Bangladesh is rarely a simple decision. Families make this move to be closer to home, to change treatment centres, or to return to a clinic they trust. Whatever the reason, the journey itself follows the same process we use everywhere: documentation first, then a single, carefully carried flight.
We do not hold an exclusive arrangement with any clinic in Bangladesh. The clinic is your choice. We coordinate with whoever you have chosen, confirming they are ready to receive your embryos before anything is booked.
The Documents You Need
Bangladesh sits outside the EU regulatory framework that shapes many of our European routes. That means the paperwork rests more on the receiving clinic's own import procedures and the country's customs requirements. We speak to the clinic directly to confirm exactly what they need, rather than assume.
Your sending clinic in the UK or Europe applies for an export licence naming the courier by name. The clinic in Bangladesh provides a one-page agreement confirming it is licensed and ready to accept the embryos. No X-ray letters go to airport security at both ends of the journey, so the tank is checked by hand and never passed through a scanner. A customs release letter is prepared for the destination airport, so the tank clears without delay. If your route includes a stopover, that transit point gets its own documentation too. We assemble the full pack and keep both clinics in step, so nothing is missing on the day you travel.
The tank travels in the cabin, not the hold. It is never checked in, never sent as cargo. It stays within reach of the courier for the entire route.
What Happens If the Tank Is Checked at Security
The no X-ray letters mean the tank is never scanned, at either airport. A security officer inspects it by hand instead, checking it against the documentation that names it. The tank is sealed at the sending clinic before the courier leaves, and that seal is tamper-evident, so anyone checking it along the way can see immediately whether it has been touched.
The seal stays in place until the receiving clinic takes delivery, where its embryologist checks it against the paperwork before opening the tank. That chain of custody, not just the courier's word, is what confirms nothing has changed along the way.
The Journey Itself
A qualified courier collects your embryos in a cryogenic tank holding minus 196 degrees. The embryologist at your sending clinic verifies them against your records before they are loaded. From there, the courier carries the tank through every leg and every connection, on board, at all times. When you land, the receiving clinic clears the tank using the customs documents prepared in advance, and its own embryologist verifies the embryos and the vessel before storage. You hear from us at each stage, so you know exactly where things stand.
What Happens If There's a Delay or a Missed Connection
The tank the courier carries has a validated hold time of up to 21 days, tested by the manufacturer. Even a long journey with a connection uses only a small part of that. The margin is built in deliberately, so a late departure or a missed connection does not put the embryos at risk on its own.
What matters is temperature, not time by itself. Above roughly minus 130 degrees, the glass transition point of the cryoprotected embryos, ice can begin to form inside the cells. A sealed, upright tank stays well clear of that within its hold time. If a flight is disrupted, the courier is rebooked onto the next available option, and the tank stays sealed throughout.
How Long It Takes
Plan for several weeks. The flight is the short part. It is the export licence and the destination clinic's own import paperwork that set the pace. Start before your treatment dates are fixed, and there is time to get the documentation right rather than rushed.
What to Know Before You Start
Confirm Bangladesh's import requirements directly with your chosen clinic, since these are set by the clinic and by national procedure rather than a single fixed rule. Make sure your storage consent with your current clinic is current, because nothing can be released until that is in order. And come to us early. The documentation and the travel arrangements come together far better when we start from day one.
Frequently Asked Questions
Can frozen embryos be transported to Bangladesh from the UK or Europe?
Yes, with the right paperwork in place: an export licence naming the courier, an import agreement from the receiving clinic, customs release for the destination airport, and airline approval for the tank as cabin baggage.
Is there a confirmed clinic partner in Bangladesh?
No. We work with whichever clinic you have chosen, confirming their readiness before anything is arranged. We hold no exclusive relationship with any single clinic on this route.
Will the embryos be safe on the journey?
Yes. They travel at minus 196 degrees, a temperature the tank holds for far longer than any journey requires. A qualified courier stays with the tank the entire way, and the receiving clinic verifies the embryos on arrival.
How long should I allow?
Several weeks. The flight is quick. The export licence and the destination clinic's import paperwork are what set the timeline. Begin before your treatment dates are fixed.
What happens if the tank is checked at security or customs?
It's inspected by hand, not scanned. The seal placed at the sending clinic stays intact and is only broken by the receiving clinic's embryologist once it arrives.
What if my courier misses a connecting flight?
The tank's validated hold time is up to 21 days, well beyond the extra hours a missed connection adds. The courier is rebooked onto the next available flight and the tank stays sealed and upright.
Without a confirmed clinic partner, how do you know the receiving clinic is ready?
We contact the clinic you have chosen directly and confirm, in writing, that it is licensed and ready to accept your embryos before anything is booked. Not having an established relationship doesn't change how carefully that step is done.
