Quick answer
Yes, frozen eggs (vitrified oocytes) can be shipped internationally for surrogacy or IVF abroad. They travel in a liquid-nitrogen dry shipper that keeps them at cryogenic temperature, accompanied by a specialized courier, with release and acceptance paperwork from both clinics, donor screening records and any import permits the destination country requires.
Key takeaways
- Vitrified eggs can travel between countries safely when the cold chain is never broken; published data show comparable survival before and after international shipment.
- The riskiest moments are handling steps (loading, unloading, transfer to storage), not the flight itself.
- Paperwork starts with both clinics: a release from the sending clinic or egg bank and written acceptance from the receiving clinic, plus donor screening and, where required, import or export permits.
- Cost depends on route, delivery type and timing, shipment volume and optional insurance — ask for a quote rather than relying on averages.
- Choose a courier that hand-carries the dewar, uses temperature loggers, avoids X-ray screening and handles customs.
Many surrogacy journeys cross at least one border: donor eggs from a bank in one country, a clinic in another, a gestational carrier in a third. In each case, the eggs have to move — and they are among the most delicate cargo in reproductive medicine. This guide explains how international frozen egg and oocyte shipping works: why vitrified eggs need special handling, which documents clinics and border authorities ask for, what drives the cost, and how to choose a carrier. If your program involves embryos rather than eggs, see our separate guides linked below; for other materials, see our IVF shipping services.
When do eggs need to be shipped internationally?
Most international egg shipments for surrogacy and IVF fall into three situations:
- Frozen donor eggs from an egg bank. Donor egg banks vitrify and store oocytes, then ship a cohort (a "lot") to the recipient's clinic, which may be in another country. We work with donor egg banks and fertility clinics worldwide — among the partners listed on our website is Ovogene, a donor egg bank.
- Your own frozen eggs. If you froze eggs at home and your surrogacy or IVF program is now abroad, the eggs must travel to the clinic that will fertilize them and create embryos for transfer to the gestational carrier.
- Changing clinics or countries mid-program. Moving stored eggs to a new clinic across a border follows the same process as a planned shipment.
In surrogacy programs, eggs are usually fertilized at the destination clinic, and the resulting embryos are transferred to the carrier. Once embryos exist, they are often what gets shipped next — that process is covered in our embryo shipping service overview and in the guides on moving embryos from one clinic to another and the legal aspects of transporting embryos for surrogacy. This article focuses on eggs.
Why frozen eggs need extra care in transit
Vitrification changed what is possible
An unfertilized egg is a single, large, water-rich cell, which made it notoriously difficult to freeze with older slow-cooling methods: ice crystals could damage it. Modern labs use vitrification — ultra-rapid cooling that turns the cell into a glass-like state without ice formation. According to a 2021 guideline from the American Society for Reproductive Medicine (ASRM), pooled data show higher oocyte survival after vitrification (about 85%) than after slow cooling (about 65%), and previously cryopreserved donor eggs are a reasonable option compared with fresh donor eggs, with no significant difference in per-transfer pregnancy rates.
What the evidence says about shipping
Shipping itself does not have to reduce egg quality. In a sibling-oocyte study presented at ESHRE 2022, 1,030 vitrified donor eggs from the same cohorts were split between the clinic of origin in Argentina and clinics in Brazil that received them by shipment in nitrogen vapor. Survival was 92.7% at the origin and 96.6% at the destination, with similar fertilization and embryo utilization rates; the authors concluded that international transport of vitrified oocytes is a safe procedure (Basile et al., Human Reproduction, 2022).
The same literature also points to where things can go wrong. An earlier report in Fertility and Sterility urged "extra caution" for vitrified oocytes, "especially when handling and transferring between shipping and long-term cryopreservation storage containers" (McDonald et al., 2011). In practice, eggs must stay at cryogenic temperature from storage tank to storage tank, and every transfer between containers must be quick, planned and done by trained staff, with temperature logged throughout.
How shipping frozen eggs internationally works, step by step
- Confirm the destination. The receiving clinic confirms it can accept frozen oocytes from the sending clinic or egg bank, and that its lab can warm eggs vitrified with the sending lab's method and device.
- Collect documents. Patients or the egg bank sign release forms, the receiving clinic issues an acceptance letter, and screening records and any permits are prepared (see the table below).
- Plan the route. The courier books transport, checks customs requirements and agrees pickup and delivery times with both labs.
- Prepare the dry shipper. A liquid nitrogen dry shipper is charged in advance so that the nitrogen is absorbed into its inner lining and there is no free liquid; a temperature data logger is attached.
- Pickup at the lab. Embryologists verify patient or donor identifiers and the number of straws or devices, then load them into the dry shipper. Both sides sign the chain-of-custody documents.
- Transit and customs. The container travels with the courier, stays upright and bypasses X-ray screening; customs declarations are handled en route.
- Delivery and handover. The receiving embryologist checks identifiers and counts, moves the eggs to long-term storage and reviews the temperature log.
Documents for shipping frozen eggs across borders
Exact requirements depend on the countries involved, so always confirm the list with both clinics before booking. A typical international egg shipment involves:
| Document | Who provides it | Why it is needed |
|---|---|---|
| Release request / consent to transfer | Patient or egg bank, via the sending clinic | Authorizes the clinic to release the eggs and transport them to the named clinic |
| Acceptance letter | Receiving clinic | Confirms the clinic is ready to receive and store the shipment |
| Courier authorization | Patient or egg bank | Grants the courier permission to carry the biological material |
| Infectious disease screening results | Donor or patient's clinic | Typically HIV 1 and 2, hepatitis B, hepatitis C and syphilis; many clinics will not accept material without them |
| Donor eligibility records (donor eggs) | Egg bank | Required by regulators in many countries, including the US |
| Import or export permit, where required | National authority or licensed clinic | Some countries regulate cross-border movement of gametes |
| Customs and air waybill documentation | Courier | Declares the contents and the shipping container correctly |
United States. Reproductive cells and tissue are regulated as HCT/Ps under FDA 21 CFR Part 1271, which requires a donor-eligibility determination based on screening and testing for relevant communicable diseases. The rules include an exception for reproductive cells donated by a sexually intimate partner of the recipient (§1271.90). Because a gestational carrier is the recipient in a surrogacy program, ask your US clinic early how donor-eligibility testing applies to your eggs.
United Kingdom. Exports of eggs and embryos by licensed clinics are overseen by the Human Fertilisation and Embryology Authority, which in 2020 clarified its guidance on exporting gametes or embryos for patients seeking surrogacy abroad.
Air transport. A correctly prepared dry shipper — one that cannot build up pressure or release liquid nitrogen in any orientation — can be described on the air waybill as "Not restricted, as per Special Provision A152" under IATA Dangerous Goods Regulations (University of Nebraska Medical Center fact sheet).
Surrogacy and gamete laws differ widely and change over time. For the legal side of surrogacy programs, see our guide to the legal aspects of transporting embryos for surrogacy, and check current rules with your clinic and a lawyer in each country.
How much does it cost to ship frozen eggs internationally?
There is no single price for shipping frozen eggs internationally, because every shipment is built around a specific route and schedule. The main cost factors are:
- Route: origin and destination cities and countries — for example, a shipment from India to the USA is priced differently from one within Europe.
- Delivery type and timing: standard or express delivery, and the shipping date.
- Volume: the amount of material and the container required.
- Optional insurance: additional cover for the shipment.
- Third-party fees: clinics or egg banks may charge their own release, handling or storage fees, and some countries require permits.
Current route ranges are listed on our pricing and delivery terms page. For an exact quote, submit a delivery request with the origin, destination and preferred dates.
Frozen eggs vs. embryos: what is different in shipping?
The equipment and cold chain are the same. The differences are paperwork and legal status: embryos usually require consent from both gamete providers, and some countries regulate them more strictly than eggs. Whether to ship eggs or embryos is a decision to make with both clinics. For embryos, start with our embryo shipping page.
How to choose a courier for international egg shipping
Before you book, ask any carrier these questions:
- Is the dewar accompanied by a staff member for the whole journey, or handed over to cargo?
- Does every container have a temperature data logger, and will you share the log with both clinics?
- How do you avoid X-ray screening at airports?
- Do you comply with IATA requirements for dry shippers?
- Who handles customs and import documents in both countries, and is support available around the clock?
- Have you shipped to or from these specific countries and clinics before?

FAQ
Can frozen eggs be shipped to another country?
Yes. Vitrified eggs can be transferred to a clinic in another country as long as the receiving clinic agrees to accept them, the required consents and screening records are in place, and the destination country allows the import. They travel in a dry shipper with a specialized courier. Rules vary by country, so confirm them with both clinics first.
Do frozen eggs survive international shipping?
Published data suggest they can. In a 2022 sibling study of 1,030 vitrified donor eggs shipped from Argentina to Brazil, survival was 92.7% at the origin clinic and 96.6% at the destination, with similar fertilization rates. Survival after warming depends mainly on the lab and egg quality; the shipment's job is to keep the cold chain unbroken.
How much does it cost to ship frozen eggs internationally?
The price depends on the route, delivery type and date, the volume of material, optional insurance and any clinic or permit fees. Because these vary so much, averages are not very useful. Check the route ranges on our pricing page and request a quote for your exact origin, destination and dates.
Can I transfer my frozen eggs to a clinic abroad for surrogacy?
In most cases, yes. Your current clinic releases the eggs on your written request, the new clinic confirms it will accept them, and a courier transports them. In a surrogacy program, the destination clinic fertilizes the eggs and transfers embryos to the gestational carrier, so check that clinic's screening requirements early.
Are frozen eggs X-rayed at the airport?
They should not be. Specialized cryo couriers arrange for reproductive material to bypass X-ray screening and keep the dewar with a staff member throughout the trip. At ARK.CRYO, reproductive cells never undergo X-rays. Ask any carrier how they handle airport security before you book.
What documents are needed to ship donor eggs internationally?
Usually a release from the egg bank or sending clinic, an acceptance letter from the receiving clinic, courier authorization, infectious disease screening results and donor eligibility records. Some countries also require import or export permits. Your clinics and courier will confirm the exact list for your route.
