5 Key Questions About Freezing Eggs for Future Pregnancy

Egg freezing, also known as oocyte cryopreservation, is a medical procedure that allows women to preserve their eggs for future use. Egg freezing offers a way for women to delay pregnancy while maintaining the option of having a biological child in the future. This can be particularly beneficial for women pursuing higher education, advancing in their careers, or those who have not yet found the right partner. It also provides a solution for women facing medical treatments, such as chemotherapy, that may affect their fertility.


The purpose of this article is to answer 10 key questions about egg freezing that you need to ask your IVF specialist or gynaecologist. By addressing these questions, we aim to provide clear and detailed insights into the process, helping you navigate your fertility preservation journey with confidence.


1. What is the Ideal Age to Freeze My Eggs? When is it Too Late?

The ideal age limit for egg freezing range to freeze eggs is typically between 32 and 36 years old. During this period, a woman’s eggs are still relatively healthy and abundant, making it an optimal time to preserve fertility for future use. Freezing eggs at a younger age generally results in higher success rates when attempting pregnancy later.


For women aged 30-40, there are additional considerations. While age 32-36 is considered ideal, women in their early 30s may still benefit significantly from egg freezing if they plan to delay pregnancy. Conversely, those approaching or in their 40s can also consider egg freezing, though success rates tend to decrease as egg quality and quantity diminish with age. It’s important to remember that age is just one factor in determining the best time to freeze eggs, and individual health conditions and fertility levels play crucial roles as well.


Factors influencing the decision based on age include:


  • Egg Quality and Quantity: Younger women typically have higher-quality eggs and more of them, which increases the chances of successful fertilization and pregnancy later.
  • Health and Hormone Levels: Healthy women with normal hormone levels are better candidates for egg freezing, regardless of age.
  • Lifestyle and Personal Goals: Professional aspirations, educational pursuits, or not having found the right partner can all influence the timing of egg freezing.
  • Medical Considerations: Women facing medical treatments, like chemotherapy, which may impact fertility, might consider egg freezing earlier.


Ultimately, while the ideal age range is 32-36, women in their 30s and early 40s should discuss their individual circumstances with a fertility specialist to make an informed decision about the best time to freeze their eggs.


2. How Do I Know That I Am a Good Candidate for Egg Freezing?

Determining whether you are a suitable candidate for egg freezing involves several criteria that your fertility specialist will assess. These criteria include:


  • Age: Generally, women under 40 years old are better candidates due to higher egg quality and quantity.
  • Hormone Levels: Normal levels of reproductive hormones, such as AMH (anti-Müllerian hormone) and FSH (follicle-stimulating hormone), indicate healthier ovarian function and better egg quality.
  • Overall Health: Good overall health, including a healthy BMI (body mass index) and no significant medical conditions affecting fertility, is important.
  • Personal Circumstances: Factors such as career goals, educational pursuits, or not currently having a partner may influence the decision to freeze eggs.
  • Medical Considerations: Women undergoing treatments that may impact fertility, such as chemotherapy or radiation therapy, may benefit from egg freezing.


Assessing these factors helps determine the likelihood of successful egg retrieval and storage. It’s important to consult with a fertility specialist who can evaluate your specific situation and provide personalized guidance on whether egg freezing is a suitable option for you. This consultation will include blood tests, and ultrasound tests to assess your ovarian reserve and hormone levels, ensuring you receive the most accurate advice based on your individual health and reproductive goals.


3. What is the Egg Freezing Procedure?

Egg freezing, also known as oocyte cryopreservation, involves a series of steps designed to preserve a woman’s fertility for future use. Here is a step-by-step outline of the egg retrieval and freezing process:

  • Ovarian Stimulation: The process begins with hormone injections, typically over a period of 10-14 days. These hormones stimulate the ovaries to produce multiple eggs, instead of the single egg that usually matures each month.
  • Monitoring: Throughout the stimulation phase, your fertility specialist will monitor your ovaries using ultrasound and blood tests to track the development of follicles (fluid-filled sacs where eggs mature).
  • Egg Retrieval: Once the follicles have reached optimal maturity, the eggs are retrieved in a minor surgical procedure called transvaginal ultrasound aspiration. This procedure is performed under sedation to minimize discomfort.
  • Fertilization (Optional): After retrieval, the eggs can be fertilized with sperm in a laboratory through a process called in vitro fertilization (IVF). This step is typically done if the eggs will be used for future pregnancy.
  • Vitrification: The retrieved eggs are then carefully frozen using a technique called vitrification. This rapid freezing process prevents ice crystals from forming inside the eggs, which could damage them. Vitrification has significantly improved egg survival rates compared to older slow-freezing methods.
  • Storage: The frozen eggs are stored in liquid nitrogen at a temperature of around -196°C (-321°F). Eggs can remain frozen indefinitely without deterioration, although regulatory guidelines may vary by country regarding storage duration.

4. What is the Egg Freezing Success Rate?

Generally, younger women have higher success rates due to the better quality and quantity of their eggs. Eggs frozen before age 30 typically exhibit higher survival rates and a greater likelihood of resulting in a successful pregnancy compared to those frozen later in life. Success rates also depend on the number of eggs frozen, with larger numbers typically improving the odds of achieving a live birth. 

On average, about 6 to 8 eggs out of 10 survive the freezing and thawing process. Success rates for achieving a live birth from these frozen eggs can range from 32% to 18%, depending on the woman’s age at the time of egg retrieval. These statistics underscore the importance of considering age and consulting with a fertility specialist to make informed decisions about egg freezing.


5. How Long Can Eggs Be Stored?

Eggs frozen for fertility preservation can typically be stored for up to 10 years in many countries, like India. Some jurisdictions allow for longer storage periods, extending up to 15 or even 20 years under certain circumstances. Current research and practice indicate that properly stored eggs can remain viable for extended periods, offering women flexibility in their reproductive choices over time. 


6. What Costs Are Involved and Does Insurance Cover the Cycle?

The costs associated with egg freezing can vary widely depending on several factors, including geographic location, clinic reputation, and specific medical needs of the individual. Typically, the process involves several expenses, such as:

  1. Consultation and Evaluation: Initial appointments to assess fertility status and suitability for egg freezing.
  2. Medication: Hormonal medications used to stimulate egg production before retrieval.
  3. Monitoring: Regular ultrasound scans and blood tests to monitor egg development.
  4. Egg Retrieval Procedure: Surgical procedure to extract eggs from the ovaries.
  5. Laboratory Fees: Costs for egg freezing, including cryopreservation and storage.
  6. Additional Costs: Potential costs for anesthesia, facility fees, and follow-up appointments.

Insurance coverage for egg freezing varies widely and may not be fully covered by all plans. It’s essential to contact your insurance provider to understand the specifics of your coverage, including:

  • Coverage Details: What aspects of the egg freezing process are covered (e.g., medications, procedures, storage).
  • Financial Responsibilities: Your out-of-pocket expenses, deductibles, and co-pays.
  • Pre-Authorization: Whether pre-authorization is required before proceeding with egg freezing.

When discussing coverage with your insurance provider, consider asking:

  • Policy Limitations: Are there any age restrictions or medical criteria that affect coverage eligibility?
  • Network Providers: Are there preferred clinics or specialists within your insurance network?
  • Appeals Process: How to appeal if certain aspects of egg freezing are not initially covered.

Understanding the costs and insurance coverage associated with egg freezing is crucial for making informed decisions about fertility preservation options.


7. What are the Risks and Side Effects Associated with Egg Freezing?

Egg freezing, a procedure used for fertility preservation, carries potential risks and side effects that individuals should consider.


Egg freezing carries risks such as ovarian hyperstimulation syndrome (OHSS), infection, and potential minor bleeding or injury during retrieval. In OHSS, the ovaries become swollen and painful due to hormonal stimulation. 


Side effects of egg freezing include mild discomfort, temporary bloating, mood swings, temporary weight gain, and rare allergic reactions to medications used during the process.


8. How Do I Prepare for the Egg Freezing Process?

Preparing for the egg freezing process involves several important steps and considerations to optimize your experience and outcomes. Before starting the procedure, your healthcare provider will typically recommend the following preparations:

  1. Medical Evaluation: Undergo a comprehensive medical evaluation to assess your reproductive health, hormone levels, and overall suitability for egg freezing.
  2. Consultation: Schedule a consultation with a fertility specialist to discuss the procedure, potential risks, expected outcomes, and any concerns you may have.
  3. Lifestyle Adjustments: Adopt a healthy lifestyle by maintaining a balanced diet, regular exercise routine, and adequate hydration to support your overall health and optimize egg quality.
  4. Medication Protocol: Understand the medication protocol prescribed for ovarian stimulation. This typically involves hormonal medications to stimulate egg production, and your healthcare provider will provide detailed instructions on their administration.
  5. Financial Planning: Review the costs associated with egg freezing, including consultations, medications, procedure fees, and storage costs, to ensure you are financially prepared.
  6. Emotional Support: Consider seeking emotional support through counseling or support groups, as the egg freezing process can be emotionally challenging.

By following these preparations, you can enhance your readiness for the egg freezing process and increase the likelihood of a successful outcome while prioritizing your health and well-being.

9. How Many Eggs Do I Need to Freeze to Increase My Chances of Future Pregnancy?

For women aged 35 and younger, it is generally recommended to freeze approximately 12 eggs to increase the chances of achieving a future pregnancy. At this age, women typically have a higher ovarian reserve and better egg quality, which can lead to a higher success rate from a smaller number of frozen eggs.


Women aged 36 to 40 are advised to freeze approximately 15 eggs to enhance their prospects of a successful pregnancy in the future. As women enter their late 30s and early 40s, ovarian reserve begins to decline, and the quality of eggs may diminish. 


For women aged 41 and older, it is generally recommended to freeze approximately 20 eggs to maximize the chances of achieving a future pregnancy. At this age, ovarian reserve is significantly reduced, and the quality of eggs may be lower, making it more challenging to achieve successful fertilization and pregnancy. 


10. What Happens When I Am Ready to Get Pregnant?

When you are ready to use your frozen eggs for pregnancy, the process typically involves several key steps to prepare the eggs for fertilization and embryo transfer:

  1. Thawing Process: The frozen eggs are carefully thawed in a controlled laboratory environment. This process requires precision to ensure the eggs remain viable for fertilization.
  2. Fertilization: Once thawed, the eggs are fertilized with sperm either through conventional in vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI). This step aims to achieve fertilization and the formation of embryos.
  3. Embryo Culture: The embryos are cultured in the laboratory for several days to monitor their development. This allows embryologists to assess their quality and viability before transfer.
  4. Embryo Transfer: High-quality embryos are selected for transfer into the uterus. This procedure is typically performed under ultrasound guidance and does not require anesthesia in most cases.
  5. Pregnancy Test: Approximately 10-14 days after embryo transfer, a blood test is conducted to determine if the embryo has successfully implanted and pregnancy has occurred.

Throughout this process, your healthcare team will provide guidance and support, ensuring that each step is carefully managed to optimize your chances of achieving a successful pregnancy. 



In conclusion, understanding the process and considerations of egg freezing is crucial for anyone considering fertility preservation. Key points to remember include the optimal age for egg freezing, which varies but generally falls between 30 and 40 years old, depending on individual circumstances. It’s important to consult with a fertility specialist to determine candidacy, undergo necessary evaluations, and discuss personalized treatment plans tailored to individual needs and goals.
