The Basics
Before diving into the details of egg development, let’s review some basics. When a baby girl is born, she has all the eggs she will ever have in her lifetime. These eggs are stored in her ovaries and are released one by one during ovulation.
Now, let’s talk about how and when these eggs develop.
The Journey of an Egg
Believe it or not, the development of a baby girl’s eggs actually starts while she is still in her mother’s womb. At around 12 weeks of gestation, the ovaries of a female fetus contain around six to seven million eggs.
However, by the time she is born, this number has dropped to around one to two million eggs. As the baby girl grows and reaches puberty, only about 300,000 of these eggs will remain.
At the onset of puberty, a girl’s ovaries will begin to release eggs each month. This process will continue until menopause, when the ovaries stop releasing eggs altogether.
What Affects Egg Development?
Several factors can affect a baby girl’s egg development. One of the most significant is her mother’s age. Women are born with a set number of eggs, and as they age, the quality and quantity of these eggs can decline.
Other factors that can affect egg development include environmental toxins, certain medical conditions, and lifestyle habits such as smoking and drinking alcohol.
Conclusion
In summary, babies develop eggs in utero starting at around 12 weeks of gestation. By the time they are born, they have around one to two million eggs, which will continue to decrease until puberty. From that point on, a girl’s ovaries will release eggs each month until menopause.
