Can a Woman Run Out of Eggs?

Short answer: yes, at some point. All of a woman’s eggs are established during fetal life, and the number naturally declines over time. But that’s only half the story. Fertility isn’t just about how many eggs you have—it’s very much about the quality of the eggs that mature. And you can support that in everyday life, without control and without perfection.

This guide gives you a down-to-earth overview of the ovarian reserve, when and how it declines, what we can (and can’t) measure, and how to give your body the best possible conditions. We’ll also look at myths, timing, and practical steps you can take at a gentle pace.

The Ovarian Reserve—what does it actually mean?

You’re born with a large reserve of tiny primordial follicles in your ovaries. By puberty the reserve is lower, and during the fertile years a small group of follicles matures each cycle while the rest naturally degenerate. So it’s completely normal for the number to fall—that’s how biology is set up.

“Running out” happens gradually and culminates in menopause, when the ovaries no longer release eggs. The run-up can be long and individual. Two people the same age can have very different reserves and still have good chances of pregnancy. That’s why it makes more sense to talk about trends than a single magic number.

Quantity vs. quality

Quantity (how many eggs) influences how often the body can produce an ovulation. Quality influences the potential of a mature egg. Both matter. If you want to dig deeper into the nuances, read our pieces on eggs and fertility: quality vs. quantity and the perspective in a woman’s clever egg cell.

How does the ovarian reserve decline with age?

The decline starts early in life and continues throughout it. In your twenties it’s often slow and steady; in your thirties it gradually accelerates; in the early forties many experience a quicker pace. These are averages—not destiny. Lifestyle, genetics, and health all play a role.

The important thing is that quality doesn’t necessarily follow a straight line for everyone. Some have strong chances in the early thirties, others for longer. That’s why it makes sense to get to know your cycle better and keep an eye on your most fertile days if pregnancy is the goal.

Can you measure the ovarian reserve?

Yes—but with caveats. Two common methods are used in clinic:

• AMH (Anti-Müllerian Hormone): A blood value that reflects the number of small follicles. It’s a reference point, not a verdict. Hormones, age, and contraception can influence the value.
• AFC (antral follicle count): An ultrasound scan early in the cycle that counts small follicles. It gives a snapshot—nothing certain about the quality of future eggs.

In short: the numbers help with planning (especially in connection with fertility treatment), but they don’t single-handedly predict how quickly you’ll conceive. They provide context, not a judgment.

“Can I top up the reserve again?”

No, not with the knowledge we have today. The number of eggs cannot be increased. But you can support the environment around the eggs and the processes that are active each month: hormonal rhythm, energy metabolism, circulation, and the cells’ own protection. That’s where everyday life makes a real difference.

What you can influence: everyday building blocks

The cells’ own defense

The body has an internal defense against everyday stressors. It’s relevant here that vitamin C, vitamin E, zinc, selenium, and riboflavin help protect cells from oxidative stress. Translate that to the kitchen: colorful vegetables and berries, whole grains, eggs and fish—plus a handful of nuts/seeds. Small choices, often. That’s the way.

Hormones and circadian rhythm

Regular sleep, steady blood sugar, and consistent movement support the fine-tuning of hormones. And it’s worth noting that vitamin B6 contributes to the regulation of hormonal activity. Think meals with whole grains, chicken/fish/eggs, potatoes, and legumes—and a daily rhythm you can repeat.

The heart as a foundation

A calm circulatory system benefits energy and recovery. Omega-3 (EPA/DHA) contributes to normal heart function. Practically, that means fatty fish 1–2 times a week (salmon, mackerel, herring)—and otherwise plant fats from olive oil, nuts, and seeds. See our green smoothie and colorful salad for easy everyday ideas.

When does it make sense to get an overview?

It’s about peace of mind. If you’re planning pregnancy within 6–12 months, it’s reasonable to have a chat with your GP or gynecologist—especially if your cycle is irregular, if you’re 35+, or if you’ve had challenges in the past. An AMH value and an early-cycle scan can be useful puzzle pieces. Not to create pressure, but to lay a kind plan.

Egg quality in everyday life—what can I do this week?

• Sleep first: Screens off for the last half hour, a consistent bedtime when possible.
• Meal rhythm: Protein + fiber + healthy fats in most meals. Steady blood sugar calms hormones.
• Movement: 20–30 minutes most days. Walks count. Training can be gentle, but consistent.
• Veggies and fish: Color on the plate and fish 1–2 times a week for EPA/DHA.
• Stress hygiene: Small breathing spaces—5 minutes of stretching, breathing, or fertility yoga.

Timing: learn your fertile window

The number of eggs is one track. Timing is another. The fertile window is typically the five days leading up to ovulation plus the day itself. If you want to work with your cycle, use the body’s own signals as a compass:

• Cervical mucus: Becomes smooth and stretchy near ovulation.
• LH tests: A positive test points to ovulation within 24–36 hours.
• Basal temperature: Rises slightly after ovulation and can confirm the pattern.

Technology can help—the body has the final say. A cycle computer can bring the data together, but practice most of all tuning into the signals. That creates calm.

Myths about eggs and age—gently debunked

• “I’m 30/32—so the train is leaving the station.” No. For most, the thirties hold good possibilities. Age is one factor among many.
• “Low AMH = no chance.” AMH says something about quantity—not directly about quality. Many conceive with lower AMH.
• “A perfect diet can increase the number of eggs.” No. But a steady, nutrient-dense diet can support the environment and energy around maturation.
• “You’re only fertile on day 14.” Not necessarily. Ovulation can shift from month to month.

What if your partner wants to contribute too?

Fertility is shared. For men, there are well-documented, approved relationships: selenium contributes to normal sperm formation, and zinc contributes to normal fertility and reproduction as well as to the maintenance of normal testosterone levels in the blood. In addition, for both of you, vitamin C, vitamin E, zinc, selenium, and riboflavin help protect cells from oxidative stress. In everyday terms: shared meals, some movement, and prioritized sleep.

Folate—think ahead

If you’re planning pregnancy, it’s relevant to think ahead: folate supports tissue growth during pregnancy. It’s not a promise of pregnancy, but part of preparation around conception. You can read more in our guide (where the anchor uses “folate,” even if the URL contains an older term): four things about folate.

When uncertainty looms—when should I seek help?

Talk to your doctor/gynecologist if your cycle is very irregular, if you can’t recognize ovulation signs over several months, if you have severe pain, or if you’ve tried for 12 months without pregnancy (6 months if you’re 35+). Information brings calm—and calm itself helps everyday life.

Mini guide: three concrete steps today

1. Build a simple meal rhythm: protein + fiber + healthy fats at most meals. See ideas in our green smoothie and salads with fruit.
2. A 20-minute walk: at least every other day. Movement supports circulation, and circulation supports energy.
3. Sleep hygiene tonight: turn off screens 30 minutes earlier and do 5 minutes of stretching or fertility yoga.

Can a woman run out of eggs? Yes—but it happens over many years, and it doesn’t mean the possibilities for pregnancy disappear overnight. Use knowledge as a framework and everyday life as your tool. Support your body with rhythm in sleep, food, and movement; protect your cells; and get to know your cycle. That builds calm, agency, and hope—in a realistic, caring way.
