Why does follicular atresia occur more frequently in smaller ovarian follicles during the luteal phase?

💡 Explanation

Follicular atresia, the degeneration of ovarian follicles, occurs because smaller follicles have fewer LH receptors, therefore they are less responsive to the low LH levels present during the luteal phase, rather than high FSH rescuing them. Consequently, they undergo apoptosis.
