“How long can my frozen eggs actually be stored?” is one of the most practical questions asked before egg freezing. This guide answers it directly — along with what happens to egg quality over time and what costs to expect.
The Technology: Why Vitrification Changed Everything
Modern egg freezing uses Vitrification — ultra-rapid freezing — rather than the slow-freeze methods used decades ago.
Why Vitrification matters:
- Freezes cells so rapidly that ice crystals cannot form
- Dramatically higher survival rates after thawing
- Post-thaw egg quality closely matches pre-freeze quality
After Vitrification, eggs are stored in liquid nitrogen at -196°C.
How Long Can Frozen Eggs Be Stored?
In theory — eggs stored in liquid nitrogen at -196°C are in a state of complete biological suspension. Degradation processes stop entirely.
In practice — there is no clearly defined maximum safe storage period in current medical guidelines. Successful pregnancies have been reported from eggs stored for more than 10 years.
Does Quality Decline Over Time?
No. This is one of the most important things to understand about egg freezing.
Egg quality is determined at the point of freezing — not by how long the eggs are stored. Eggs frozen at age 30 and used at age 38 retain the quality of a 30-year-old’s eggs.
This is precisely why freezing earlier, when egg quality is higher, gives better long-term outcomes.
What Does Affect Quality
While storage duration doesn’t affect quality, other factors do:
1. Egg quality at the time of freezing — the most important variable
2. Lab technique during freezing — quality of Vitrification protocol and embryologist expertise
3. Thawing process — proper execution of the thaw is equally critical
4. Consistency of storage temperature — any temperature fluctuation in the storage system can affect outcomes
Annual Storage Fees After Year One
GFC’s Egg Freezing Promo package includes 1 year of storage within the 159,000 THB price. After that, annual storage fees apply.

FAQ
Are eggs frozen for 5 years still usable?
Yes. Storage duration does not degrade eggs stored in liquid nitrogen. Successful pregnancies have been reported from eggs stored significantly longer than 5 years.
Can I store eggs for 10+ years?
In principle, yes. Contact GFC to discuss long-term storage planning and associated costs.
If I move abroad, can my eggs be transferred to another clinic?
International transfer of frozen biological material involves complex legal and logistical requirements. Contact GFC directly to discuss your situation.
How do I know my eggs are being stored safely?
GFC maintains continuous temperature monitoring and regular system checks. You can contact GFC at any time to confirm the status of your stored eggs.
What if I decide I no longer want to use my eggs?
Please consult with your doctor at GFC to discuss the available options.
What is the survival rate of eggs after thawing?
With standard Vitrification technique, post-thaw survival rates are high. Your doctor will provide specific figures relevant to your case at consultation.
How do I check on my stored eggs?
Contact GFC via Line @gfcclinic or call 097-484-5335.
Summary
Frozen eggs stored in liquid nitrogen via Vitrification do not degrade over time. Quality is set at the point of freezing — which is why freezing earlier produces better long-term outcomes.
Annual storage fees apply after the first year included in GFC’s packages.
