How Many Eggs Does a Woman Have? At Birth, Age 30, 40, More

Published in Reproductive Biology 1 min read

The number of eggs a woman has decreases significantly with age. At birth, a female typically has around 1-2 million eggs. By age 30, that number drops to approximately 100,000-150,000. By 35, it's estimated to be around 80,000, and by 40, the number of eggs left could be as low as 5,000 to 10,000. This decline in egg count is a natural part of the aging process and is a primary factor in decreasing fertility as women age.

Here's a general overview of the egg count at different ages:

  • Birth: 1-2 million eggs
  • Puberty: 300,000 to 500,000 eggs
  • Age 30: 100,000-150,000 eggs
  • Age 35: 80,000 eggs
  • Age 40: 5,000 to 10,000 eggs
  • Menopause: Egg count is depleted

Important Note: These are general estimations, and the actual number of eggs a woman has can vary significantly based on individual factors such as genetics, lifestyle, and health conditions.
