Frozen embryos can fly, packed in a liquid nitrogen dry shipper. The fertility field generally avoids putting them through airport X-ray as a precaution. A hand-carry courier keeps the shipper in the cabin and arranges for it to be screened without going through the X-ray machine.
Can embryos go on a plane?
Yes. Embryos travel in a dry shipper, an insulated container in which the liquid nitrogen is absorbed into a lining. Because there's no free liquid, a correctly prepared dry shipper isn't classed as dangerous goods for air travel. It can be carried in the cabin by a courier, or shipped by air cargo.
Why avoid X-ray?
Embryos are frozen and stable at cryogenic temperatures, and there isn't firm evidence about the effect of a single airport scan. But embryos are precious and irreplaceable, and there's no benefit to exposing them to radiation if it can be avoided. That's why clinics, embryologists and specialist couriers generally treat "no X-ray" as best practice.
Checked baggage and cargo are screened as a matter of routine, and the owner has no say in how. That's one reason many families prefer a courier who keeps the shipper with them.
How a hand-carry courier handles security
- The shipper stays with the courier at all times, as cabin baggage.
- It isn't put on the X-ray belt. Screening is handled by other means, with the shipper never leaving the courier's care.
- The courier carries the paperwork that explains what the shipper is and why it's travelling.
- The shipper is kept upright and steady throughout, which helps it hold temperature.
At Vessel, this is standard on every journey: your embryos are never checked as baggage and never go through airport X-ray screening.
What if I travel with them myself?
Some clinics let patients collect embryos themselves, though many require a professional courier. If you're considering it, check your clinic's rules, your airline's policy on dry shippers and the security procedures at each airport on your route, including any connections. It's very doable, but it's a lot to manage on a day that already matters.
International flights and customs
Customs checks add another stage on international journeys. A specialist courier carries the documents customs expects to see and stays with the shipper throughout. See international embryo shipping for the full picture.
Frequently asked questions
Can airport X-ray damage frozen embryos?
There isn't firm evidence either way about a single airport scan. Because embryos are irreplaceable, the fertility field generally avoids X-ray as a precaution, and hand-carry couriers keep them out of the scanner.
Can I put embryos in checked luggage?
It isn't recommended. Checked bags are screened routinely and handled out of your sight, and a dry shipper needs to stay upright. Embryos should travel with a person, in the cabin.
Is a dry shipper allowed on a plane?
Yes. A correctly prepared dry shipper contains no free liquid nitrogen, so it isn't classed as dangerous goods for air travel.
