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 ...
As follicles develop into the early antral phase and require gonadotropin support for growth, an increase in follicular atresia can occur in this pool of follicles secondary to hormonal disturbances as well as direct effects.
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.
Atretic Follicle. Degeneration of follicle (atresia) can occur at any stage of development. The granulosa cells undergo apoptosis and consequently, the oocyte degenerates. The basement that separated the oocyte from granulosa cells often thickens to become the glassy membrane.

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.
