Histological view of an ovarian follicle. The egg is located within the smaller ring.
Follicular atresia refers to the process in which a follicle fails to develop, thus preventing it from ovulating and releasing an egg.[1] It is a normal, naturally occurring progression that occurs as mammalian ovaries age. Approximately 1% of mammalian follicles in ovaries undergo ovulation and the remaining 99% of follicles go through follicular atresia as they cycle through the growth phases. In summary, follicular atresia is a process that leads to the follicular loss and loss of oocytes, and any disturbance or loss of functionality of this process can lead to many other conditions.[2]
