Yes, you can ship frozen embryos to another country, and the flight is the easy part. The sending clinic has to agree to release them, the receiving clinic has to accept them and, in many countries, hold an import permit, and a courier carries them in a dry shipper the whole way. This guide walks through each step in order. If you only need the short answer, see can frozen embryos be shipped internationally. Moving embryos between two US clinics is simpler; that is our embryo shipping service within the US.
Why Do People Ship Embryos Internationally?
There are several common reasons families ship embryos across borders:
- Treatment abroad: IVF treatment in countries like Mexico, Czech Republic, or Spain can be significantly more affordable
- Surrogacy arrangements: Working with gestational carriers in other countries
- Relocation: Moving to a new country and bringing your frozen embryos
- Donor programs: Receiving donor embryos from international sources
- Legal requirements: Some countries have laws that affect where you can use embryos
Step-by-Step International Embryo Shipping Process
Step 1: Choose a Reputable Courier Service
Not all shipping services are equal. For international embryo transport, look for:
- IATA DGR Certification: Essential for transporting dangerous goods (liquid nitrogen)
- Hand-carry protocol: Your embryos should travel in the aircraft cabin, not cargo
- Documentation expertise: International shipping requires extensive paperwork
- Track record: Ask about their success rate and years of experience
- Temperature monitoring: Real-time tracking and temperature logging
Step 2: Coordinate with Both Clinics
Before shipping begins, your courier should contact:
- Sending clinic: To understand their release protocols and documentation
- Receiving clinic: To confirm acceptance procedures and timing
At GuardianCryo, we coordinate with both embryology labs before you sign any contract.
Step 3: Gather Required Documentation
International embryo shipping typically requires:
- Clinic release authorization: From your current fertility clinic
- Patient consent forms: Your written permission for transport
- Chain of custody documents: Tracking the embryos' journey
- Import permits: Required by the destination country (e.g., HFEA for UK)
- Customs declarations: For border crossing
- Health certificates: Some countries require these
Step 4: Prepare for Pickup
On pickup day:
- The courier meets your embryologist at the clinic
- Patient identity and specimen details are verified
- Embryos are loaded into the cryogenic dewar
- Tamper-evident seals are applied
- Chain of custody documentation begins
Step 5: Transit and Delivery
During transit:
- Embryos remain in the aircraft cabin (not cargo hold)
- Courier requests hand-inspection at all security checkpoints (no X-rays)
- Courier check-ins and temperature monitoring throughout
- Direct delivery to receiving embryologist
- Final verification and transfer of custody
International Embryo Shipping Costs
The price depends mostly on the route and how many flights the courier takes, not on how many embryos travel. Our embryo shipping cost guide lists the current ranges by route, and a written quote for your route comes within 24 hours. Clinic release fees, import permits and duties are set by the clinics and authorities and are not part of the courier price.
Country-Specific Requirements
United Kingdom (HFEA)
The UK requires a Special Direction from the Human Fertilisation and Embryology Authority (HFEA) before importing embryos. This process takes 4-6 weeks, so plan ahead.
European Union
EU countries follow the Tissue and Cells Directive. Requirements vary by country, but generally include health screening documentation and import permits.
Mexico
Mexico has relatively straightforward requirements for embryo import. Customs documentation and clinic authorization are typically sufficient.
Canada
Health Canada requires certain documentation, and provincial health authorities may have additional requirements.
Tips for Smooth International Embryo Shipping
1. Start early: Begin the process 6-8 weeks before your desired shipping date
2. Verify clinic compatibility: Ensure both clinics can handle the transfer
3. Understand costs upfront: Get all-inclusive quotes with no hidden fees
4. Keep copies of everything: Documentation is critical for international shipping
5. Stay in communication: Your courier should provide regular updates
6. Have a backup plan: Know what happens if flights are delayed
Common Questions
How long can embryos safely travel?
With proper cryogenic equipment, embryos can safely travel well beyond any normal transit window. Most international shipments complete within 2-5 days.
Will my embryos go through X-ray machines?
Not with a reputable hand-carry service. Couriers carry official documentation requesting manual inspection.
What if my flight is delayed?
Our dewars have extended holding capacity, and we have contingency plans for rerouting if needed.
Can I ship embryos anywhere in the world?
Most countries accept embryo imports, but some have restrictions. We can advise on specific routes.

Lo que la gente hace mal al enviar embriones al extranjero, según los relatos de pacientes
En las rutas internacionales, el tanque rara vez es el problema. La clínica receptora, las reglas sobre donantes y los permisos sí lo son, y estos relatos muestran dónde falló cada uno.
La primera pregunta es si alguna clínica los va a aceptar
El error: Contratar un mensajero antes de que una clínica receptora hubiera aceptado por escrito. Importar embriones es menos común de lo que los pacientes esperan, sobre todo a Estados Unidos.
“The first question we were asked was 'have you found a clinic willing to accept them?'”Reddit r/Surrogate (UK and Australia to US): leer la fuente (en inglés)
Cómo evitarlo: La aceptación por escrito de la clínica receptora es el primer paso. No damos una fecha sin eso.
Transporte internacional en mano, de clínica a clínica →¿Se pueden enviar embriones del Reino Unido a Estados Unidos? El material de donante a menudo no se puede
El error: Meses buscando rutas hacia Estados Unidos antes de enterarse de que la evaluación de elegibilidad de donantes de la FDA excluye a donantes con antecedentes de residencia en el Reino Unido.
“USA was similar but they do not accept British embryos due to mad cow disease so i was not allowed”Reddit r/IVF: leer la fuente (en inglés)
Cómo evitarlo: Para cualquier ruta de entrada a Estados Unidos con gametos de donante, haga la verificación de elegibilidad de donantes de la FDA en el expediente antes de reservar cualquier cosa. Los embriones de sus propios gametos se tratan de manera diferente.
Reglas de la FDA para material reproductivo importado →El transportista canceló tres semanas antes porque la aduana era demasiado lenta
El error: Depender de una red de carga cuyo tanque aguanta unos siete días cuando la aduana despacha solo en días hábiles y un cierre de gobierno retrasó el procesamiento.
“they are cancelling our service due to recent troubles with US customs being too slow. Our embryos need to arrive at the clinic in the US in approximately 3 weeks”Reddit r/IVF (Canada to US): leer la fuente (en inglés)
Cómo evitarlo: Transporte en mano con documentación preaprobada y un tanque cuyo tiempo de conservación cubra el peor escenario de despacho. Sin fechas de ciclo hasta que el cruce esté confirmado.
Entrada a la aduana de Estados Unidos para embriones, explicada →Dos mensajeros rechazaron Ciudad de México por el permiso de COFEPRIS
El error: Suponer que cualquier mensajero puede hacer México. El permiso de importación es el obstáculo más largo y algunos transportistas no toman la ruta.
“We were actually turned down by both BioCouriers and IVF Couriers because of challenges with Mexico City customs/COFEPRIS requirements.”Reddit r/IVF (San Diego to Mexico City): leer la fuente (en inglés)
Cómo evitarlo: Presente primero el permiso de COFEPRIS y reserve los vuelos después. Pregunte al mensajero quién es dueño del permiso y cuál es el plazo indicado.
Cotice una ruta a México con el permiso incluido →Un mes de correos antes de que el tanque se moviera
El error: Esperar que el tiempo de tránsito sea el plazo total. La conversación a tres bandas entre dos clínicas y el mensajero es lo que toma el mes.
“We did our IVF in San Francisco and shipped our embryos to Asia early this year. Allot at least a month of back and forth emails.”Reddit r/IVF (21 points): leer la fuente (en inglés)
Cómo evitarlo: Un solo coordinador debería manejar la conversación para que usted no sea el gerente del proyecto. Otra paciente en un traslado del Reino Unido a Australia escribió que ella misma tuvo que mantener hablando a ambas clínicas y al transportista.
