Egg Freezing Success: Why Egg Quality Actually Matters

Egg freezing can be a great option if you're unsure about having kids, undecided on timing, or just want a backup option, since life can be so unpredictable. But here's what fertility clinics don't always tell you upfront: Freezing your eggs isn't a guarantee.

What does this mean, exactly? You might assume that freezing more eggs is a better insurance policy. But whether those eggs actually work when you decide to use them depends on the quality. Essentially, not all eggs can become viable embryos that result in successful pregnancies.

Egg freezing is often sold as a hedge against age. But if you're freezing poor-quality eggs, are you really buying the peace of mind you're paying for? Ideally, you’d have insight into the quality of your eggs so you can feel like the investment is worthwhile. The good news: AI-powered technology, like Future Fertility's VIOLET™ report, is now making it possible to assess egg quality at the time of retrieval — so you're not just counting eggs, you're understanding them. This is about making an informed decision with as much information as possible, not just half of it.

Here's why quality matters for egg freezing success, what affects the quality, and how recent innovations may be able to tell you more about the potential of your eggs.

Does egg quality matter for egg freezing?

The short answer: Yes, absolutely. Quality matters for egg freezing just as much (if not more) than quantity.

Frozen eggs maintain the quality they had at the time of freezing. Think of frozen blueberries you might buy at the grocery store. They're ideally frozen at peak ripeness, any bad ones are discarded before freezing, and the quality of the frozen berries doesn't improve or decline in storage.

The age factor

Higher maternal age is associated with lower egg quality and a reduced chance of those eggs becoming viable embryos. So, if you freeze your eggs when you're 35, those eggs will remain "35-year-old quality," even if you use them at 42.

The math problem

Retrieving 20 eggs during a freezing cycle might seem pretty good. But if only two or three are high enough quality to develop into a healthy embryo, your odds of a successful pregnancy aren't as high as you may have thought. 

When fertility specialists talk about egg quality, they're talking about how capable the egg is of developing into a healthy embryo and pregnancy. The egg has two main parts: the nucleus, which contains the chromosomes that make up half of the baby's genetic material, and the surrounding cytoplasm, which acts as the egg's "support system," providing the energy and tools the embryo needs to grow and develop in the early stages. Both matter.

This isn't meant to be discouraging — egg freezing can absolutely be a worthwhile endeavor. It's meant to be informative. Knowing your egg quality can help you make better decisions about fertility.

So, how do you know what egg quality you're working with? We'll get to this ahead.

How egg quality impacts your egg freezing outcomes

Better egg quality is associated with higher fertilization rates and a greater chance of successful embryo implantation, resulting in more live births.

A 2025 review of research published in the International Journal of Women's Health found that women under 35 produce not only substantially more eggs than those over 35 during a hormone-stimulated retrieval process but also eggs with a higher chance of surviving the thawing stage and successfully fertilizing.

According to the 2025 review, age is the biggest predictor of egg quality, but it's not the only factor. In other words, two 38-year-olds can have very different egg quality.

Egg attrition ("drop-off") rate

It’s also important to understand that not every egg retrieved will make it through each stage of development to result in a live birth. As your eggs progress to the embryo stage (and beyond), fewer continue at each step.

A 2023 study published in the Journal of Clinical Medicine looked at 167 women who froze their eggs between January 2016 and March 2022. The average age of the women was 37.1, and an average of 9.5 eggs were retrieved each cycle. Of the eggs that ended up being taken out of cryopreservation, 74% survived the thawing process, 67% were fertilized, 48% of the transferred embryos resulted in pregnancy, and 35% resulted in a live birth.

This means there could be a big discrepancy between the egg count you're freezing and how many actually have a shot at a successful pregnancy.

How to know your egg quality before you freeze

Common tests that are run before egg freezing, like ovarian reserve that checks for AMH (anti-müllerian hormone), FSH (follicle-stimulating hormone), and AFC (antral follicle count), measure egg quantity, not quality.

You have to go through the egg retrieval to gain insights into your egg quality. That’s because each egg is different and needs to be assessed individually, so it is not possible to know the quality before you begin the egg-freezing process. 

The new option: AI-powered egg quality assessment

The exciting news is that technology is improving. For example, Future Fertility partners with fertility clinics to offer AI-powered egg quality assessments at the time of retrieval.

Their VIOLET™ technology uses AI to analyze images of your eggs after retrieval and generate a personal prediction of each egg's likelihood of developing into a blastocyst, the day-5 or day-6 embryo stage required for transfer. VIOLET™ even provides a personalized prediction of your chances of having a baby.

What makes this different from anything that existed before is that it's per egg, not per patient. The standard of care has always relied on age-based statistics, which assume everyone in the same age group has roughly the same egg quality. That’s not how biology works. VIOLET™, developed using a dataset of over 650,000 egg images and their outcomes, can detect patterns invisible to the human eye, including features that even experienced embryologists can't reliably assess on visual inspection alone.

Without this technology, you may be told how many eggs were retrieved — or given general expectations based on your age. This can leave you wondering if your eggs are good quality, whether you have as many as you need, or why your IVF cycle didn't work as expected.

But with this innovation, you can make more informed decisions when freezing your eggs and how many cycles to plan for. After all, you're making a major investment in your future. Shouldn't you know what you're investing in?

How do I get one of these reports?

AI-powered egg quality reports may be offered through your fertility clinic as part of your treatment.

Future Fertility’s software is integrated into the clinic’s lab workflow. After your eggs are retrieved, images are taken in the lab as part of routine care and securely analyzed to generate a personalized report for your care team.

Your provider will then share and review the report with you, helping you understand what the results may mean for your treatment and next steps.

Can you improve egg quality before egg freezing?

You might be able to optimize your egg quality with some lifestyle tweaks, but you can't reverse age-related decline.

Here are a few evidence-based things you might consider trying:

• Omega-3 fatty acids, such as fish oil pills

• CoQ10 (coenzyme Q10) or ubiquinol

• Vitamin D supplementation

• The Mediterranean diet

• Sleep and stress management

• Avoiding environmental toxins, like pollution

• Reducing alcohol consumption or quitting smoking

Eggs take about three months to mature. So, some healthcare providers might suggest making these changes at least 90 days or so before your egg retrieval.

Having realistic expectations

The science of egg freezing and IVF gets better every year. Still, it's good to have realistic expectations. Healthy habits can support egg health in a general sense, but they won't make 40-year-old eggs perform like 30-year-old eggs.

Ask your provider if they recommend supplements or lifestyle changes for egg freezing prep and when they suggest starting.

Is it worth freezing eggs at 39?

It depends on your individual situation. But for many people in their late 30s, yes, it can be worth freezing eggs — with realistic expectations.

What the data says

With the 2023 study mentioned earlier, women in their late 30s retrieved 9.5 eggs per cycle. Since quality can decline with age, more are needed for favorable odds.

A 2017 study published in the journal Human Reproduction used a mathematical model to predict how many frozen eggs women at different ages would need to have a 75% chance of a live birth. It found that 37-year-olds would need 20 eggs, and women at 42 would need 61 eggs. So, if you're approaching 40, you may need to do multiple cycles to get enough eggs.

Factors to consider

Your ovarian reserve can give you a rough idea of how many eggs you might be able to retrieve in a cycle (this can be checked with an ultrasound or blood test). When deciding whether to freeze your eggs in your late 30s, you'll also want to consider your financial resources, family-building goals, and personal timeline.

Why knowing your egg quality matters

It’s not currently possible to directly measure the quality of your eggs before freezing, beyond general age-related trends. However, understanding how egg quality typically changes with age can still help you make informed decisions about when to freeze and what to expect.

Once you’ve frozen your eggs, using VIOLET™ to analyze their unique characteristics can provide more personalized insight. This information can help you decide whether to pursue additional freezing cycles or consider alternative paths, depending on your goals and timeline.

For those who complete multiple cycles, a VIOLET™ summary report can offer a more comprehensive view of your overall chances for success across all of your frozen eggs.

That said, if you're sure you want to freeze your eggs, timing still matters. Egg quality tends to decline more rapidly in the early 40s and beyond, so delaying can reduce the likelihood of success.

Some people choose to freeze their eggs around age 39, recognizing they may ultimately need donor eggs, but wanting to try with their own first. The goal is to support informed, personalized decision-making at every step.

Making the decision: Quality + quantity = your full picture

Egg quantity and quality both matter, but quality often gets overlooked. In the end, the choice to freeze should be a holistic decision based on:

• Your age and ovarian reserve

• Your timeline (how soon you might want to use the eggs)

• Your financial resources and whether you can do multiple cycles if needed

• Your backup plans

• Whether AI-powered quality assessment is available at your clinic

Ask your clinic about egg quality insights to see if this is something that can be assessed with your retrieval. Understanding quality helps you set realistic expectations rather than creating false hope or unnecessary anxiety.

Future Fertility's VIOLET™ report gives you info on how many eggs you've frozen, each egg's likelihood of becoming a blastocyst (the stage it would be transferred as an embryo), and a prediction of your personal chances of a live birth based on your egg quality.

It’s not just when you freeze, it’s what you freeze

Egg freezing is a powerful tool and an empowering choice. But quality ultimately determines whether it works. While age matters, it's not destiny. Quality varies from person to person.

Having information about your egg quality, rather than just your age-based statistical chances, can help you make informed choices about your fertility and family planning.

So, if you're considering freezing, don't just focus on how many eggs you might get per cycle. Ask about quality, too.

Egg freezing shouldn't be a "hope for the best" scenario. You deserve data-driven clarity. Whether you freeze at 30, 35, or 40, knowing what you're working with helps you plan, prepare, and feel confident in your decisions.
