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.
Atresia folikuler adalah pecahnya folikel ovarian, yang terdiri dari oosit yang dikelilingi oleh sel granulosa dan sel-sel teka internal dan eksternal. Kejadian tersebut terjadi secara berkelanjutan sepanjang kehidupan wanita, saat mereka lahir dengan jutaan folikel namun hanya akan berovulasi sebanyak sekitar 400 kali pada masa hidup mereka ...
If a follicle is not recruited, it goes through a process called atresia, during which the oocyte and granulosa cells within the basal lamina die and are replaced by fibrous tissue.

Atresia is a normal process in the ovary that occurs at all stages of follicular development throughout female reproductive life (Gosden and Spears 1997). When a primordial follicle is activated, it is destined to enter the growing follicle pool or to undergo atresia.
The normal, common fate of a follicle or female germ cell is known as atresia - ovulation represents an exceptional destiny. The above plot shows clearly how the number of germ cells decreases from the 20th week in order that they are all gone by about 50 years of age.
Introduction. Throughout ovarian development and function in mammals, a highly orchestrated, periodic process known as follicular atresia occurs that destroys and eliminates follicles and oocytes from the ovary. Follicular atresia is pervasive.
