eli5: how are human girls already born with all the eggs they’ll ever have?

552 views

I’ve seen videos showing the scale of a human egg and it’s visible to the naked eye- it’s definitely not as small as i thought it would be. So how are girls born with millions of eggs already? Im thinking that large of an amount would take up a considerable amount of space. And how do girls lose eggs from birth if they dont have their first period til adolescence? Since im assuming eggs are mainly lost through periods, excluding trauma or ovarian disorders.

Eggs are constantly deteriorating. The vast, vast majority of eggs never ovulate, they just degrade and die. Periods are the body disposing of an egg after it was primed for conception. Unused eggs die far more often and without all the uncomfortable cramps and stuff
