Females are born with roughly 1–2 million eggs in their ovaries, and no new eggs are made after birth.

Quick Scoop: Key Facts

  • Around 6–7 million eggs (oocytes) are present in a female fetus at about 20 weeks of pregnancy.
  • By birth , this number has naturally dropped to about 1–2 million eggs.
  • By puberty , only about 300,000–500,000 remain in the ovaries.
  • Over a lifetime, only about 300–400 of these eggs are actually ovulated; the rest gradually die off through a natural process called atresia.
  • By menopause , there are usually fewer than 1,000 eggs left.

Mini Breakdown: Before Birth to Menopause

Before birth

  • A female fetus reaches peak egg count (about 6–7 million) around mid-pregnancy (20 weeks gestation).
  • From that point on, egg numbers start to decline even before she is born.

At birth and puberty

  • At birth : about 1–2 million eggs.
  • At puberty : about 300,000–500,000 eggs remain in the ovarian “reserve.”

Adult life and menopause

  • During the reproductive years, roughly 1,000 eggs are recruited each month, but typically only one fully matures and is released during ovulation.
  • Across a lifetime, only about 300–400 eggs are actually released; the others quietly break down and are reabsorbed by the body.
  • Menopause usually occurs when the reserve has fallen to under 1,000 eggs.

Is There Variation Between Females?

  • There is natural variation: some sources estimate birth counts can range widely, with some individuals having significantly more or fewer eggs than the typical 1–2 million.
  • Genetics, smoking, certain medical treatments (like chemotherapy), and some health conditions can accelerate egg loss or affect egg quality.

Simple Illustration

If you imagine all the eggs you are born with as a huge library, birth is like starting with 1–2 million “books.” Over the years, most books quietly disappear from the shelves, and only a few hundred are ever actually “checked out” (ovulated).

TL;DR: When people search “how many eggs are females born with,” the most widely cited medical estimate is about 1–2 million eggs at birth , out of a peak of 6–7 million during fetal life.
