When Should You Freeze Your Eggs?

There is no single "perfect" age to freeze your eggs. The right time depends on your age, ovarian reserve, personal circumstances, and family-building goals.

However, one factor matters more than any other: **the age of your eggs**.

While many women focus on the number of eggs they have left, fertility specialists know that **egg quality declines with age**, and this has the greatest impact on the chances of achieving a healthy pregnancy.

The goal of egg freezing is to preserve your eggs **before this natural decline becomes significant**.

Why Does Age Matter So Much?

Women are born with all the eggs they will ever have.

Over time:

• The number of remaining eggs gradually decreases.
• The quality of those eggs also declines.
• Eggs become more likely to contain the wrong number of chromosomes.

Chromosomes carry our genetic information. A healthy human egg should contain **23 chromosomes**. After fertilization, the embryo should have **46 chromosomes**—23 from the egg and 23 from the sperm.

Sometimes, however, an egg contains too many or too few chromosomes. This is called **aneuploidy**.

Most aneuploid embryos do not implant successfully, result in miscarriage, or are affected by serious genetic conditions. Fortunately, the body naturally prevents many of these embryos from developing.

As women get older, the likelihood that an egg will be chromosomally normal decreases.

This is the main biological reason fertility declines with age.

How Does Egg Quality Change With Age?

Research from large IVF studies has shown that the proportion of chromosomally normal embryos decreases gradually with maternal age.

These figures represent average outcomes from IVF cycles and illustrate the natural effect of aging on egg quality.

These are population averages. Every woman is different, and egg quality cannot be predicted by age alone.

Importantly, **the age that matters is the age when your eggs are frozen—not when you use them**.

For example, eggs frozen at age 33 generally retain the quality of a 33-year-old's eggs, even if they are used ten years later.

What Is the Best Age to Freeze Your Eggs?

There is no universal answer, but fertility specialists generally consider the following:

The best time to freeze your eggs is usually **before you need them**, rather than waiting until pregnancy becomes urgent.

It's Not Just About Age

Age is the strongest predictor of egg quality, but it is not the only factor.

Your fertility specialist will also consider:

AMH (Anti-Müllerian Hormone)

AMH is a blood test that estimates your ovarian reserve—the number of eggs remaining in your ovaries.

A higher AMH often means you may respond well to ovarian stimulation, but it **does not measure egg quality** or predict your ability to conceive naturally.

Antral Follicle Count (AFC)

An ultrasound performed at the beginning of your menstrual cycle can count the small follicles developing in your ovaries.

Together, AMH and AFC help estimate how many eggs may be collected during an egg freezing cycle.

Your Personal Situation

Other important factors include:

• Whether you hope to have one child or several
• Whether you have a partner
• Your career or education plans
• A family history of early menopause
• Endometriosis or previous ovarian surgery
• Cancer treatment or other medical conditions affecting fertility

Egg freezing is not simply a medical decision—it is also a personal and life-planning decision.

Questions to Ask Yourself

If you're considering egg freezing, it may help to ask yourself:

• How old am I today?
• When would I realistically like to have children?
• Do I hope to have one child or more?
• What does my AMH test show?
• What is my antral follicle count (AFC)?
• Would I regret not preserving my fertility if pregnancy takes longer than expected?

A fertility consultation can help answer these questions and provide personalized guidance.

Common Misconceptions

"My AMH is normal, so I can wait."

Not necessarily.

AMH tells you approximately **how many eggs remain**, but **not how healthy those eggs are**. Egg quality continues to decline naturally with age, even if AMH remains reassuring.

"I'm only 36—I'm still young."

Many women conceive naturally after 35, but fertility gradually becomes less predictable from the mid-30s onward.

Freezing eggs earlier generally means a higher proportion of healthy eggs and may reduce the number of stimulation cycles needed.

"If I freeze my eggs, I can delay pregnancy indefinitely."

Egg freezing preserves the age of your eggs—not the age of your body.

Although younger eggs improve the chances of creating healthy embryos, pregnancy later in life is also influenced by your overall health and pregnancy-related risks associated with maternal age.

Bboom Tip

Egg freezing is not about guaranteeing a future pregnancy—it's about preserving your options while egg quality is still favorable.

If you're unsure whether now is the right time, don't think of the decision as a simple "yes" or "no." Instead, start with a fertility assessment. Your age, AMH, ultrasound, and family-building goals together provide a much clearer picture than any single test.

The best decision is an informed one—and understanding your fertility today gives you the greatest number of options for tomorrow.
