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 aren’t lost through periods, the period is the result of a lost egg.
eggs are stored in the ovaries. Once a month one (or sometimes more) eggs are released into the uterus.
the uterus wall is lined with nutrient-rich tissue, when an egg is fertilized it attaches itself to uterus wall and uses said lining as a nutrient source to “feed” the egg and aid in development.
When an egg isn’t fertilized it simply shrivels up and dies and that lining is then shed. The shed is what the “period” is made of. the “cramps” girls complain of is literally the uterine muscles contracting to shed the lining.
but eggs can die prematurely too, before they are released from the ovaries. just like any cell they go through stages of development and aren’t full-sized in the ovaries. only when they reach full maturity are they released, and many will die well before that.
