Women only have 300-400 eggs that get released roughly 8-12 times a year so this means by the time a women is 35, they will lose roughly 264 eggs assuming that they are 35 at worst (and assuming puberty hits at 13) and at best they will lose 176 eggs.
During fetal life, there are about 6 million to 7 million eggs. From this time, no new eggs are produced. At birth, there are approximately 1 million eggs; and by the time of puberty, only about 300,000 remain. Of these, only 300 to 400 will be ovulated during a woman's reproductive lifetime.
