How Many Eggs Does a Woman Have?

Published in Egg Count 2 mins read

A woman's egg count varies significantly throughout her life, decreasing from millions at birth to near zero by menopause.

Egg Count at Different Life Stages:

  • At Birth: A baby girl is born with approximately 1 to 2 million eggs (oocytes). Some sources cite a range of 6-7 million. [Source: Multiple sources including Medical News Today, Healthline, Natural Cycles]

  • Puberty: By puberty, the number has significantly decreased to approximately 300,000-400,000. [Source: Unidentified source within provided text]

  • Age 30: The number continues to decline. A woman in her 30s might have around 100,000-150,000 eggs remaining. [Source: CNY Fertility]

  • Age 35: The decline accelerates. Estimates suggest around 80,000 eggs remain. [Source: CNY Fertility]

  • Menopause: By menopause, the supply of eggs is essentially depleted, with only around 1000 remaining. [Source: Medical News Today]

Important Considerations:

  • Egg Quality: The number of eggs is not the only factor in fertility. Egg quality also diminishes with age, affecting the chances of conception.

  • Individual Variation: The exact number of eggs varies widely among individuals. Genetics and lifestyle factors play a role. [Source: Apricity Fertility]

  • Egg Release: Over a woman's lifetime, only about 500 eggs will be released during ovulation. [Source: Clearblue]

In summary:

The number of eggs a woman possesses decreases dramatically throughout her life, starting from millions at birth and dwindling to nearly zero by menopause. This reduction significantly impacts fertility potential.
