Infertility FAQs - How Many Eggs are Women Born With?

At birth, most women had around 2 million ooctyes or eggs contained within immature folliciles.

According to a recent article in "Sexuality, Reproduction and Menopause":

At 28 weeks' gestation, a developing female fetus has a maximum of 6 to 7 million immature eggs
At birth, around 2 million eggs remain within immature follicles
At puberty, there are about 500,000 follicles remaining
At 38 years of age, around 25,000 follicles remain
From 38 to about 51 years of age, follicle loss accelerates until the ovaries stop working
