The mature follicle is at least 10 mm in diameter, typically elevating the surface of the ovary (Graafian follicle). During the ovulation, the thin wall of the follicle facing the ovarian surface ruptures and the pressurizedliquor folliculi expels the oocyte with the corona radiata.

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.
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.
Most ovarian follicles never complete their maturation and degenerate by a process called atresia during fetal development, early postnatal life, and prior to the onset of puberty. Atresia is mediated by apoptosis of the follicular/granulosa cells.
In this review, we discuss the factors that govern follicular growth and atresia, with a special focus on their regulation by granulosa cells. First, ovarian folliculogenesis in adult life is outlined.
Ovarian follicle atresia is a normal physiological phenomenon that eliminates unnecessary ovarian follicles by a noninflammatory process and can occur at any stage of follicular development, from primordial to ovulatory.
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
