When you’re entrusting your previous cargo to a transport service, one question overshadows all others: Will they arrive safe and viable? These aren’t just samples—they’re your hopes for a future family, carrying years of emotional and financial investment.
At LifeParcel, we understand this weight, which is why our embryologist-led team uses state-of-the-art dry shippers to protect your fertility materials at -196°C, achieving a 100% success rate across 2,500+ missions.
In this guide, we’ll break down how these fertility material shipping containers work, address your fears of damage or loss, and show how LifeParcel’s hand-carry approach ensures peace of mind. Let’s dive into the science and care that safeguard your dreams.
The container that protects your future family
The specialized containers used for IVF material transport are called dry shippers. They’re precision-engineered medical devices designed for one critical job: maintaining your genetic material at exactly -196°C throughout the entire journey.
How these fertility material shipping containers work:
- Absorbed liquid nitrogen: The containers are pre-charged with liquid nitrogen that gets absorbed into specialized porous materials lining the inner walls
- Vapor-phase environment: As the absorbed nitrogen slowly evaporates, it creates a controlled cold vapor that surrounds your materials without direct liquid contact
- Vacuum-sealed insulation: Multiple layers of insulation and vacuum barriers prevent external heat from penetrating the container
- Pressure regulation: Built-in venting systems safely release vapor pressure while maintaining temperature stability
Why your materials need this level of protection
Your frozen eggs, sperm, or embryos exist in a state of biological suspension at -196°C. At this temperature:
Cellular activity completely stops: Your materials are essentially paused in time, maintaining their current state indefinitely
Ice crystal formation is prevented: The rapid freezing process (called vitrification) creates a glass-like state without damaging ice crystals
Biological processes halt: No aging, no degradation, no cellular damage occurs when temperature is maintained properly
What happens if temperature rises:
- Minor fluctuations (-190°C to -185°C): Potentially manageable but should trigger monitoring alerts
- Moderate increases (-180°C to -150°C): Risk of cellular stress begins; ice crystal formation may start
- Significant warming (-100°C to -80°C): High risk of cellular damage within hours
- Severe temperature loss (above -80°C): Rapid degradation and likely complete loss of viability
Important note: These are general estimates based on cryopreservation principles. Actual tolerance varies by material type, duration of exposure, and individual sample characteristics. Any temperature deviation should be addressed immediately by trained professionals.
This is why the container protecting your fertility materials must be absolutely reliable—there’s no room for error when dealing with temperatures this extreme.
Inside the container: how protection works
The absorption system
Instead of liquid nitrogen sloshing around loose, the container uses specially designed absorbent materials that soak up the liquid nitrogen like a sponge. This creates several advantages:
- No spill risk: Even if the container is dropped or turned upside down, nothing leaks out
- Stable temperature: The absorbed nitrogen releases vapor consistently, maintaining steady conditions
- Safety compliance: Airlines and shipping companies approve these containers because there’s no free liquid
Temperature monitoring technology
The most cutting-edge fertility material shipping containers, such as the ones we use at LifeParcel, include:
- Digital temperature loggers: Continuous monitoring throughout the journey
- Real-time alerts: Immediate notification if temperature begins to drift
- Data recording: Complete temperature history for verification at delivery
- Battery backup: Monitoring continues even during power disruptions
Multi-layer protection
The container walls typically include:
- Vacuum insulation: Similar to a thermos but much more advanced
- Reflective barriers: Bounce heat away from the inner chamber
- Shock absorption: Protect contents from drops and impacts during handling
- Pressure regulation: Prevent dangerous pressure buildup
How long do these containers work?
Standard capacity: Most fertility material shipping containers maintain proper temperature for 7-14 days, depending on:
- Container size and design
- How well it was initially charged with liquid nitrogen
- Environmental conditions during transport
- How often it’s opened (each opening releases cold vapor)
Typical transport needs: Since most international fertility material transport takes 2-5 days, standard containers usually provide substantial safety margin for short delays.
Extended capacity options: At LifeParcel, we use the most advanced fertility material shipping containers, which can maintain -196°C for up to 21 days, offering unmatched reliability for complex international routes, such as surrogacy across 32+ countries. This extended capacity ensures your eggs, sperm, or embryos remain protected even during unforeseen delays, giving you peace of mind for your fertility journey.
What happens during transport
The process varies by provider, but top-tier services like LifeParcel have strict protocols in place for safety and a gold standard of care, ensuring your fertility material shipping container protects your eggs, sperm, or embryos at every step.
At pickup
Your transport provider should:
- Verify the container was properly charged within 24 hours
- Check temperature readings before loading your materials
- Document the transfer from clinic storage to transport container
- Seal and label the container according to international shipping regulations
During transit
Throughout the journey:
- Temperature monitoring continues automatically
- GPS tracking shows container location at all times
- Alerts trigger if any parameters go outside safe ranges
- Professional couriers maintain custody without handoffs
At delivery
Upon arrival:
- Temperature logs are verified to confirm conditions remained stable
- Materials are transferred quickly to permanent clinic storage
- Documentation is completed for chain of custody
- Any issues are immediately reported and addressed
What could go wrong (and how it’s prevented)
Container failure
Risk: Insulation failure or nitrogen depletion
Prevention: Pre-transport testing, backup monitoring, emergency protocols
Physical damage
Risk: Drops, impacts, or rough handling
Prevention: Shock-resistant construction, protective outer cases, trained handlers
Temperature deviation
Risk: Heat exposure or insulation problems
Prevention: Real-time monitoring, immediate alerts, emergency response plans
Transport delays
Risk: Extended transport beyond container capacity
Prevention: Multiple-day safety margins, emergency recharging capabilities
Questions to ask your transport provider
“What type of containers do you use and what’s their capacity?” Know the specific model and how long it can maintain temperature.
“How do you monitor temperature during transport?” Ensure real-time monitoring, not just data logging.
“What happens if the container approaches its capacity limit?” Understand emergency protocols for extended delays.
“Can I see the temperature data during transport?” Verify you’ll have access to monitoring information.
“What backup plans exist if the container fails?” Know what emergency options are available.
