This is what happens to the one that start maturing before puberty, for example, so they undergo atresia, a kind of programmed self- destruction.

例如，青春期前开始成熟卵泡会发生这种情况，所们会经历锁，一种程自我毁灭。

Now, sometimes secondary amenorrhea can occur because of premature ovarian failure - which is when the ovarian follicles undergo accelerated atresia and get depleted before the age of 40, resulting in early menopause.

有时，继发性经原因是卵巢早衰，即当卵巢滤泡加速锁，在40岁前消耗殆尽，造成提前绝经。
