Ask the CryoStork®: Is it really safe to transport something as fragile as embryos?
Many intended parents navigating the IVF journey may need to ship their frozen embryos between fertility clinics or storage facilities. This could be for access to a different physician, geographic relocation, changing treatment plans, or the use of a gestational carrier. Whatever the reason, it’s natural for stressors to appear during this step in your journey, considering what this irreplaceable shipment represents and the time and financial investment it may have taken to get to this point. When you ship your frozen embryos, you deserve the reassurance that they’re being handled with care and deep consideration for the story behind them. When Cryoport Systems coordinates a frozen embryo transit, every step of the process is designed to protect these irreplaceable materials.
How cryogenic transport safeguards frozen embryos
To sum it up quickly, your frozen embryos must be cold enough to stay protected during the entire time it takes to move them. We’ll break that down with some more specifics. A cryogenic transport refers to the movement of biological and live cell materials at cryogenic temperatures (below -150°C) to maintain cellular integrity. This low temperature range is necessary to safely and successfully ship frozen embryos and other temperature-sensitive materials. We use validated, custom-engineered shipping equipment that can maintain cryogenic temperatures for the time needed to transport sensitive materials, with plenty of wiggle room in case of unpredictable travel delays.
Making sure shipping systems meet cleanliness and performance standards
The safety of frozen embryos relies not only on maintaining the correct temperature, but also on the shipping system’s condition. Before one of our shipping systems is used to ship frozen embryos, it will undergo a rigorous set of tests and cleaning to ensure it is safe to use. Each shipper gets fully requalified, which means our trusted teams check its performance, temperature stability, and structural integrity. This step ensures that the shipper is in top performing shape for your shipment. It’s also understandable to worry about the cleanliness of the shipping system your frozen embryos will be placed in. To help keep these precious materials safe, we also follow a strict cleaning protocol. Our Veri-Clean® decontamination process eliminates 99.9999% of contaminants like bacteria, viruses, and fungi—and it’s done by a real person. With this thorough cleaning step, our equipment keeps your frozen embryos protected from cross-contamination. Firm decontamination and requalification procedures help ensure that each shipping system meets high standards for performance and cleanliness. To protect frozen embryos, it’s important for this part of your journey to be handled with thoughtful intention.
Keeping track of your frozen embryos
One of the most stressful parts of transporting frozen embryos to a new location is not knowing what’s happening during the move, and many intended parents feel uncertainty during this step. Continuous monitoring technology shares real-time data on location, temperature, and status of sensitive materials 24/7. If any of these parameters deviate from what they should be, rest assured that a team member is aware and handling it. You can trust that our skilled staff are keeping a watchful eye on your frozen embryos, because we know how important they are to your family.
Establishing standards for safe transport
When shipping frozen embryos, it’s important to follow specific procedures designed to keep sensitive materials safe. Providers can demonstrate their reliability by complying with internationally recognized quality standards. Cryoport Systems was the first supply chain company to become certified in ISO 21973, a global standard for the transportation of human cells for therapeutic use. This certification ensures that our methods are safe, with risk mitigation and high-quality operations. For intended parents, that means you can count on the fact that our behind-the-scenes processes follow the highest standards, and that applies to your most precious shipment as well. We want to make sure that every time we ship something as meaningful as frozen embryos, our processes are consistent and predictable.
