how many eggs do women have
Women don’t make new eggs during their lifetime; they are born with a large “stock,” and that number steadily falls with age.
Quick Scoop: How many eggs do women have?
- Around 6–7 million immature eggs (oocytes) in the ovaries at about 20 weeks of fetal life (while still in the womb).
- About 1–2 million eggs at birth.
- Roughly 300,000–400,000 left by puberty.
- Over the entire reproductive lifetime, only 300–400 eggs are actually ovulated ; the rest naturally die off.
- By the late 30s, many women are down to tens of thousands of eggs, and by around menopause (average early 50s), the usable number is very low (around 1,000 or fewer and not functioning well).
So the simple answer is:
A woman is born with about 1–2 million eggs, but only a few hundred will ever be released, and the rest gradually disappear over time.
Mini sections
1. Why the numbers drop
- Eggs are lost every day through a natural process called atresia (they break down and are reabsorbed), not just during periods.
- In the teens and 20s, dozens of eggs start to mature each month, but usually only one is released; the others are lost.
- As age increases, both egg count and egg quality decline, which is why fertility generally gets lower after the mid‑30s.
2. A rough age-by-age picture
- Fetal life (20 weeks): ~6–7 million eggs.
- Birth: ~1–2 million eggs.
- Puberty: ~300,000–400,000 eggs.
- Around 30: often estimated at roughly 100,000–150,000 on average (big individual variation).
- Around 40: often around 5,000–10,000 remaining.
- Menopause: around 1,000 eggs left, but they are no longer capable of supporting regular cycles or pregnancy.
These are averages. Some people have more, some fewer, and conditions like endometriosis, chemotherapy, or smoking can speed up the loss.
3. Can you measure “how many eggs” you have?
Doctors cannot count every egg, but they can estimate “ovarian reserve” using:
- AMH blood test (anti‑Müllerian hormone): higher AMH usually suggests more remaining follicles; lower AMH suggests fewer.
- FSH and estradiol blood tests: high FSH on day 3 of the cycle can signal lower reserve.
- Transvaginal ultrasound to count small follicles (antral follicle count), another indicator of egg pool size.
These tests do not guarantee whether you can or can’t get pregnant, but they give a rough idea of remaining egg quantity.
4. Story-style example
Imagine someone named Sara:
- Before she was born, her ovaries held millions of tiny egg cells.
- At birth, that was down to about 2 million. By the time she got her first period, maybe 300,000–400,000 were left.
- Through her 20s, each month her body chose one egg to ovulate and quietly let many others fade away.
- By her late 30s, the pool shrank fast; both the number and quality of her eggs dropped.
- By her early 50s, her egg reserve was so low and inactive that she reached menopause.
This is the typical pattern, though real life varies a lot from person to person.
5. “Latest news” + forum-style angle
In recent years, there’s been a lot of online discussion and “latest news” about:
- Egg freezing becoming more common, with many people in their late 20s to mid‑30s considering it to preserve fertility as egg count and quality decline.
- Apps and at‑home tests that estimate ovarian reserve using AMH and cycle tracking, which often show up in forum threads where people compare results and timelines.
- Conversations in fertility forums where users share numbers like “my AMH is X” or “my antral follicle count is Y” and ask what that means for their egg supply and chances of pregnancy, highlighting how confusing these numbers can feel.
In forum discussions, people often say “I only have X eggs left,” but in reality, medicine can only estimate reserve, not count every egg one by one.
TL;DR:
Women are born with about 1–2 million eggs, have roughly 300,000–400,000 at
puberty, and only 300–400 are ever ovulated; the rest naturally disappear as
they age until menopause.
