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 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.
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.
Ovary follicle atresia refers to a complex hormonally driven process in the mammalian ovary that involves the degeneration and loss of ovarian follicles. AI generated definition based on: Knobil and Neill's Physiology of Reproduction (Fourth Edition), 2015
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 ...

The majority of ovarian follicles undergo atresia, a hormonally controlled apoptotic process. Monitoring apoptotic DNA fragmentation provides a quantitative and sensitive endpoint to study the hormonal regulation of atresia in ovarian follicles.
