Follicle Selection And Growth In The Domestic Hen Ovary
, 2015 Ovarian follicle selection and development in domestic hens is highly regulated. A single small follicle (approximately 6-8 mm in diameter) is selected daily and enters the pre-ovulatory hierarchy, continuing to grow until ovulation occurs.

The Journal of Reproduction and Development, 2020 Magang geese exhibit a unique characteristic of follicular development, with eight largest orderly arranged pre-ovulatory follicles in the abdominal cavity. However, little is known about the mechanisms underlying this follicular development.

Computer-Generated Ovaries to Assist Follicle Counting Experiments [PDF]
, 2015 Precise estimation of the number of follicles in ovaries is of key importance in the field of reproductive biology, both from a developmental point of view, where follicle numbers are determined at specific time points, as well as from a therapeutic ...

FSHR-mTOR-HIF1 signaling alleviates mouse follicles from AMPK-induced atresia
Cell Reports, 2023 Summary: The majority of activated ovarian follicles undergo atresia during reproductive life in mammals, and only a small number of follicles are ovulated.

Follicle Selection in the Avian Ovary [PDF]
Reproduction in Domestic Animals, 2012 ContentsFollicle development in the highly efficient laying hen is characterized by a well‐organized follicular hierarchy. This is not the case in other chickens such as the broiler breeder hen that has excessive follicle development and lower reproductive efficiency.

Theory of Follicle Selection: I. Hypotheses and Examples [PDF]
Biology of Reproduction, 1987 A theory of follicle selection is developed in which all follicles, ovulatory and atretic, inherit the same developmental plan for responding to circulating concentrations of estradiol and gonadotropins. In the model, this plan is represented by a maturation surface that determines the rate of follicle growth as a function of follicle maturity and ...
