Menopause might be delayed indefinitely, suggests new Utah research
At birth, ovaries in girls can contain about a million tiny structures called primordial follicles, each of which contains an egg cell.

At birth, ovaries in girls can contain about a million tiny structures called primordial follicles, each of which contains an egg cell. As girls grow and experience adulthood, most of these follicles will die while only one follicle will survive each month to ovulate a mature egg.
