1 Δεκ 1994 · GREATER THAN 99% of ovarian follicles undergo a degenerative process called atresia during reproductive life. Extending earlier morphological analysis, recent studies have demonstrated that apoptotic cell death is the molecular mechanism underlying follicle atresia.
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.
Follicular atresia occurs on a monthly basis, as a cohort of up to 50 follicles may be recruited, resulting in one dominant follicle proceeding to ovulation while the others are absorbed. However, 80% of follicular atresia may be due to a gonadotropin-independent process.
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 ...
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.
1. 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.
28 Νοε 2023 · In the present study, we established classification criteria for human small antral follicle atresia based on their morphological and molecular characteristics. During the early stages of atresia (type 1), the mural granulosa cells bordering the antral cavity become loose and pyknotic (antral atresia).
