Embryo, Sperm & Egg Courier — Frequently Asked Questions
Straight answers on embryo shipping, IVF courier logistics, embryo transport containers and transporting frozen embryos, sperm and eggs internationally — from a specialist biological courier, not a general parcel service.
What You Need to Transport Frozen Embryos Internationally
International embryo transport involves more than packing a dry shipper and booking a flight. The exact requirements vary by origin country, destination country and specific clinic policy, so treat the list below as a general guide, not a checklist that applies identically everywhere — it is strongly recommended to verify the specifics with your clinic's own legal and regulatory team before a transport date is fixed. In general, a complete international embryo shipment involves:
Formal written consent confirming who is authorising the transfer and to which receiving clinic.
Confirms the courier is acting on the patient's behalf, plus a letter addressed to origin airport security requesting manual inspection.
Confirms the receiving clinic's willingness to accept the material, plus the equivalent No X-Ray letter for the destination airport.
Many countries require the sending clinic to apply for an export licence through their Ministry of Health, specifically naming the courier who will carry the material. This process and its timeline vary significantly by country.
Prepared in advance so the receiving clinic can clear the shipment through destination customs without delay on arrival.
The embryo transport container itself — a cryogenic dry shipper charged and validated before collection, packaged to UN3373 dangerous-goods standards.
Arranged directly with the airline's cargo or dangerous-goods division ahead of each specific booking — not a blanket, one-time approval.
Someone trained and certified to handle and hand-carry biological substances, travelling with the container for the entire journey.
Is Transporting Frozen Embryos Safe?
Is it safe to transport frozen embryos, sperm, or eggs?
Yes, when handled by a specialist biological courier. Frozen embryos, sperm and eggs travel in validated cryogenic dry shippers maintained at −196°C, with dual-witness verification at collection and delivery and full chain-of-custody documentation throughout. Our quality management system is ISO 9001 certified. Whether a specific sample is a good candidate for transport at a given time is a clinical question for your embryologist — we are a logistics provider, not a medical practitioner, and don't advise on clinical suitability.
How long can sperm and eggs survive during transport?
A validated cryogenic dry shipper, such as the MVE SC 4/3 we use, holds −196°C for well beyond any realistic transport window — typically in excess of ten days without needing external power. In practice, transit time is not the limiting factor when a correctly charged, validated dry shipper is used throughout. For guidance specific to your samples' storage history, that's a question for your treating embryologist rather than for us.
How is the temperature maintained during transport?
We use vapour-phase liquid nitrogen dry shippers, charged with liquid nitrogen before collection and holding a stable −196°C passively — no batteries, no external power, no active refrigeration to fail mid-journey. The vessel travels as cabin baggage with the courier at all times, so temperature and custody are never out of sight.
What's the difference between fresh and frozen embryo transport?
Frozen (vitrified) embryos are stable inside a validated dry shipper for the entire journey, so logistics can be planned around clinic availability and documentation rather than the clock. Fresh embryo or sample transport is time-critical — it must reach the receiving clinic within a narrow window, which means different equipment, different routing decisions, and far less flexibility on timing. We handle both, but they are logistically very different services.
Embryo Shipping & IVF Courier Logistics
Embryo international transport involves more coordination than a standard parcel shipment — here's what's actually involved.
Can you ship frozen embryos, sperm, or eggs internationally?
Yes. International embryo shipping is our core service — we coordinate embryo, sperm and egg transport between clinics across the UK, Europe, the Middle East, Asia and beyond, to over 30 countries to date. Every international transfer is supported by export and import clinic agreements, customs documentation, and UN3373-compliant packaging specific to the origin and destination involved.
Can I hand-carry embryos or sperm on a plane?
Our couriers hand-carry the cryogenic dry shipper as cabin baggage on every journey — it is never checked in and never sent as cargo. This isn't something a patient typically does themselves: it requires a UN3373-qualified courier, airline carry-on approval arranged in advance for that specific booking, and full documentation for security and customs at both ends. That coordination is what we provide.
What embryo transport container do you use?
We use the MVE SC 4/3, a vapour-phase liquid nitrogen dry shipper. It's DGR-exempt but still requires airline approval for every individual booking, and it is carried as cabin baggage at all times — never checked in, never sent as cargo. This is the same embryo transport container used across every route we run, so the equipment and protocol stay consistent regardless of origin or destination.
Are there couriers that accept biological samples like embryos and sperm, and can deliver them internationally?
Yes — Embryo Links is exactly this: a courier who can deliver biological samples internationally, including embryos, sperm, eggs, and stem cells, between clinics. Our staff hold UN3373 qualification for biological substance transport, and our quality management system is ISO 9001 certified. Not every general courier is set up for this — cryogenic biological samples need specific equipment, training and documentation that standard parcel couriers don't carry.
Cost, Delays & What If Something Goes Wrong
How much does it cost to ship frozen embryos or sperm?
There is no single fixed price — cost depends on the service type, the country of origin and destination, and the specific documentation each route requires. Rather than publish a generic figure that wouldn't reflect your actual journey, we ask for a few details about your route and provide a specific quotation.
What happens if the shipment is delayed or lost?
The dry shipper's extended hold time is deliberately built in as a margin, so a reasonable delay — a missed connection, a documentation hold-up — does not put the sample at risk on its own. If a delay does occur, our couriers coordinate directly and proactively with both the sending and receiving clinic rather than leaving you to chase updates. Liability and insurance terms for your specific transfer are set out in the signed service agreement, and we recommend independent legal advice and your own specialist insurance if you want that additional layer of cover.
Staying Informed During Transport
Can I track my sperm or embryo shipment in real time?
You receive a WhatsApp message at each key stage of the journey — collection confirmed, en route, arrived, and delivered — so you always know where things stand. This is stage-based status messaging rather than continuous live GPS tracking, which reflects how the transfer actually happens: your courier is travelling with the sample in the aircraft cabin, not a parcel moving through an automated depot network.
Country & Region-Specific Questions
Can I transport embryos or sperm in or out of the UK?
Yes — UK import and export transport is a core part of what we do, including UK-to-Europe and UK-to-Middle East routes. UK-origin exports typically involve an HFEA-related export licence coordinated through your clinic; HFEA licensing applies to the clinics themselves, not to us as the courier, and we recommend confirming the specific requirements with your clinic's regulatory team ahead of a planned transfer.
Can I ship embryos, egg cells, and sperm to or from Africa?
We coordinate biological sample transport to clinics across 30+ countries worldwide to date, including facilitating routes to and from fertility clinics on the African continent. Requirements vary significantly by country, so get in touch with your specific origin and destination and we'll confirm what documentation that route needs.
Beyond Embryo Transport
Do you also handle stem cell transport or cord blood transportation?
Yes. Alongside embryo, egg and sperm courier services, we provide stem cell transport and cord blood transportation — cryopreserved HSC and cord blood units at −196°C, fresh apheresis products and bone marrow harvests at +2–8°C, and cell therapy products including CAR-T cells, with 24/7 operational availability. See our full stem cell and cord blood transport service for detail.
Can you help with embryo import into a receiving clinic?
Yes. Embryo import coordination is part of every international transfer we run — a one-page agreement confirming the receiving clinic's willingness to accept the material, a No X-Ray letter addressed to the destination airport, and customs release documentation prepared in advance so the receiving clinic can clear the shipment without delay on arrival.
