Embryo Courier to Iran & Tehran:
What the Route Actually Looks Like

Iran and IVF: A Story Most People Don't Know

When people think of Iran, assisted reproduction is rarely the first thing that comes to mind. And yet Iran is home to one of the most active and well-developed IVF industries in the Muslim world. Tehran alone has dozens of fertility clinics — several of which are internationally recognised for the quality of their embryologists and laboratory standards.

The reasons are rooted in history, religion, and economics. Under Shia Islamic jurisprudence, certain forms of assisted reproduction — including IVF using the couple's own gametes, and in many rulings, egg donation — have been permissible since the 1990s. This religious clarity, combined with the relatively low cost of treatment and the high standard of clinics, means that thousands of families use Iranian fertility services every year.

Many of those families are not in Iran. Across Europe, there are substantial Iranian diaspora communities — in Germany, the Netherlands, France, Sweden, and beyond — many of whom maintain strong ties to Iranian clinics for language, family proximity, and cost reasons. When treatment works, they are left with a practical question they may not have fully planned for: the specimens need to move. That is where a courier comes in.

The Tehran Route: What It Actually Involves

There are no direct commercial flights between Europe and Iran. Connections through cities like Istanbul, Dubai, or Doha mean that a typical journey from Europe to Tehran runs 8 to 12 hours, depending on the departure point and routing. That is well within the operating window of a high-quality cryogenic dry shipper — a container that maintains liquid nitrogen temperatures of −196 °C without needing to be actively powered, and holds well in excess of the duration of any Europe–Tehran journey.

The route begins with collection from the sending clinic — full dual-witness handover, temperature verification, documentation signed and sealed before the courier leaves. At the departure airport, biological specimens have specific handling procedures, as they do at Tehran Imam Khomeini International Airport on arrival. Iranian customs requires precise documentation prepared in advance for biological material crossing the border in either direction. At the receiving clinic, handover is direct, witnessed, and recorded by the receiving embryologist. For shipments moving in the opposite direction — collection in Tehran, delivery to a European clinic — the same rigour applies in reverse, with full regulatory documentation for the destination country.

The courier travels with the specimens in the aircraft cabin — never in the hold, never out of sight. When the preparation is right, the physical transit is uneventful. Every complication we have seen on this route began on paper, not in the air.

What Makes This Route Different

Many international biological specimen couriers work the well-worn European routes — between major clinic cities where documentation is familiar, airports are predictable, and procedures are established.

The Tehran route is different in several ways that make experience on it genuinely important:

Documentation across two regulatory systems

Clinics across Europe each operate under their own national regulatory framework — HFEA in the UK, equivalent authorities in Germany, France, the Netherlands, and elsewhere. Iranian clinics operate under Iranian Ministry of Health protocols. A courier transporting specimens between a European clinic and an Iranian one needs documentation that satisfies both systems — and needs to know which documents each side requires, in what format, and with what signatures.

Iranian customs for biological material

Biological specimens — embryos, eggs, sperm — are classified in a specific category for Iranian customs. From the runs we have done on this route, we know that arriving with the wrong documentation, or documentation that has not been prepared in the correct format, risks delays. Delays on a cryo-shipment are not acceptable. What happens at the border is almost entirely determined by what was prepared before the courier left.

Language

At Tehran IKA, at the receiving clinic, in correspondence with Iranian embryologists — Farsi is the working language. A courier who does not have Farsi-language capability in their team is operating with a significant limitation on this route that cannot be papered over.

فارسی — Farsi on This Route

On the Tehran route, Farsi is not a nice-to-have — it is the working language of the receiving clinic, the customs process, and the airport handover. Our team includes Farsi speakers, which means the coordination that needs to happen on this route happens in the right language.

In practice, pre-journey correspondence with the Tehran clinic — documentation requests, handover arrangements, import coordination — is conducted in Farsi. Customs and import documentation is prepared in Farsi where the Iranian authorities require it. At the Tehran-side handover and airport process, a Farsi-capable team member leads the coordination. Where the receiving clinic or airport contact needs to work in Farsi, that is how we work.

This is not a translation layer added on top of a standard service — it is simply how this route is run. هماهنگی این مسیر به زبان فارسی انجام می‌شود.

The Possibilities

Every family's situation is different, and we make no assumptions about yours. The scenarios below are examples of situations we have encountered on this route — not suggestions, not recommendations, just illustrations of what has been possible for others.

A Note on Documentation

Documentation is where most problems on international routes originate. Not at airport security. Not in the air. On paper — or rather, the absence of the right paper at the right moment.

For the Tehran route, the documentation we prepare and carry includes:

• The sending clinic's export authorisation and specimen manifest, in the format required by their national regulatory authority
• The receiving clinic's import acceptance letter, in Farsi and where required in English
• Biological material declaration for Iranian customs, in the required format
• Temperature log from the cryogenic container's data logger, confirming maintained conditions throughout transit
• Chain-of-custody records signed at collection, at each handover point, and at delivery
• Courier identification and authorisation letters from both sending and receiving clinics

Every document is prepared before the courier travels. Nothing is improvised at the airport. From what we have seen on this route, a customs or airport official who can verify exactly what is being carried, by whom, and on whose authorisation will wave a well-prepared shipment through without difficulty. The transit itself is the easy part — if the paperwork is right.

Get in Touch

If you have specimens that need to move between Europe and Iran — or if you are a clinic coordinating a shipment on a patient's behalf — contact us directly. Tell us where the specimens are, where they need to go, and what stage the clinic documentation is at. We will tell you exactly what the process involves, what we need from the sending and receiving clinics, and how long it takes to put in place.

We are available in English and Farsi. If the route is possible, we will tell you so plainly. If there is something that needs to be resolved before it can proceed, we will tell you that too.
