Egg freezing is the process of storing eggs for long-term preservation. When this process is done correctly, the eggs are stored for many years in stable conditions. This egg storage for fertility preservation may cause doubt about what happens to these eggs over time, especially after 5, 10, or 15 years. We explain how these eggs are stored, what happens to them over time, their success rate, and further processing.

Pregatips
Egg storage gives you time, freedom and flexibility over your plans to get pregnant. This egg storage can be done by freezing eggs. You may wonder about changes in stored eggs from year to year, such as loss of integrity or quality, or becoming nonfunctional after a certain time.
In this article:
The reason for egg freezing is that this process ensures the long-term preservation of eggs.

What Does Egg Freezing Actually Preserve?


Egg freezing preserves:

Freezing eggs is done through a process called vitrification, which prevents the formation of ice crystals. The egg cells are damaged when ice crystals form and may lose their potential to fertilise in the future. To avoid this ice crystal formation, vitrification is preferred for modern egg freezing.

How Are Frozen Eggs Stored for Many Years?


For the eggs to be stored with good potential and structural integrity, certain conditions must be maintained. This egg storage requires liquid nitrogen tanks maintained at 196°C. This temperature is crucial for cell stability, inactivating the metabolic processes during storage and preventing cell damage over time.



The tanks are monitored regularly with utmost care. The well-equipped fertility labs use:


Safety Systems Used in Fertility Clinics



  • Monitoring systems to record temperature
  • Backup tanks
  • Changes signalled by alarms
  • Safety protocols
  • Embryology teams to monitor the cells

What Happens to Eggs Stored for 5 Years?


Utmost care and the methods used for storing eggs in a frozen state enable them to remain in the same state and good condition even after 5 years.

What stays the same?

The eggs remain stable, with the same genetic content and egg quality, and their age remains the same inside the storage tanks.

Why Age at Freezing Matters More


The concern regarding egg storage is your age at the time of egg freezing, not how long the eggs are stored in the frozen tanks. As pregnancy is better at ages 25-32 than at nearly 40, eggs frozen at 25-32 years of age yield better results than those frozen at 38-40 years of age.

What Happens to Eggs Stored for 10 Years?

If the eggs are frozen in your twenties or early thirties, then they are supposed to be used after 10 years. These frozen eggs are stable even after 10 years.

What can change after 10 years?


Although the frozen eggs remain stable after 10 years, there may be changes in your relationship, pregnancy chances, and your health, as well as your pregnancy policies, terms and conditions, and document requirements in the legal context.
Do success rates fall after 10 years?
Frozen eggs remain stable for up to 10 years when stored under appropriate conditions. Egg potential depends on egg survival after thawing and the techniques used.
It also depends on lab expertise. Above all, it depends mostly on the quality of vitrification and the maturity of the frozen egg.

What Happens to Eggs Stored for 15 Years?


The eggs remain stable for 5 years and 10 years. If the situation is for 15 years, you may wonder what the case is. Under the lab-provided conditions and proper storage, the eggs are frozen and stored for an extended period without losing their potential.

Are 15-year storage eggs still usable?

Based on lab maintenance, frozen eggs for 15 years can also be thawed and used for pregnancy. Most cases resulted in positive outcomes for pregnancies.

What becomes more important at 15 years?

At long-term storage for 15 years, the concerned factors are:

  • Standards of storage clinic
  • Document and consent for the clinic terms
  • Renewal policy
  • Current health condition
  • Pregnancy chances
Apart from healthy eggs, there are many other challenges to cross at an older age. These challenges may be your:

  • Increasing blood pressure
  • Diabetic prone during the gestation period
  • Preeclampsia
  • Chances of C-section

Do Frozen Eggs “Expire” Like Food or Medicine?

Frozen eggs are living cells and not manufactured products that degrade gradually and expire. As they are living cells, you should monitor storage conditions from time to time to ensure their preservation.

Apart from storage duration, consistent monitoring of storage conditions, equipment conditions, and lab handling procedures with adequate protocols is crucial for storing frozen eggs.


Does Egg Quality Change While Frozen?

Generally, egg quality remains stable under frozen conditions. If they are of good quality and potential, their quality is sustained even after freezing. If at all there are any issues at the time of freezing, they may not be of high quality.

The egg quality depends upon two situations:
Quality at the Time of Freezing: Quality of the egg at the time of freezing, such as egg age and the response to stimuli.

Egg Survival After Thawing: The quality of the egg after thawing, as some eggs may not survive thawing. This depends on the labs and their standard thawing techniques, along with lab expertise.


What Should You Consider Before Using Long-Stored Eggs?

There are certain considerations when using long-stored eggs, such as those stored for 5, 10, or 15 years. The concerns are:

Reproductive health at the time of using a stored egg.

Your current health matters more than the health condition at the time of freezing.

Your health checklist may include:

  • Uterus condition
  • Presence of polyps or fibroids, if any
  • Levels of hormones
  • Thyroid issues
  • Glucose levels
  • Emotional strength and readiness for pregnancy
An emotional blend may cause you to feel fear and stress, as well as excitement, if you are about to use the stored eggs. You may hope for a successful outcome, ignoring the unpredictable fertility concerns.

Despite these uncountable queries and emotional distractions, you may feel reassured by your partner's support during these appointments, decision-making and waiting periods, and medication intake.


Checklist Before Using Frozen Eggs

A clear checklist can help you with your frozen eggs for years if you are unsure how to use them.

  • Check with your renewal policy
  • Confirm storage contract
  • Update your contact information with the storage clinic
  • Clarify the monitoring system of the tank
  • Take a count of mature eggs stored by requesting them
  • Discuss the success chances based on your age
  • Prepare a timeline for your fertility journey
  • Plan the finances required for IVF treatment
  • Consult your doctor for your pregnancy health
  • If you are anxious, you are advised to take counselling


If the eggs are frozen under appropriate lab conditions in liquid nitrogen tanks, they can be stored for 5, 10, or even 15 years and remain stable, with good potential. The duration of egg storage does not affect their age or potential. The factors that impact it are your age at the time of egg freezing, lab quality, and your health condition when you are ready to use them. This egg freezing is a secure and valuable option for future family planning, provided it is supported by the right guidance and emotional well-being.
