Reproductive Medicine and Biology, 2021 Background The process of follicle development is tightly regulated by pituitary gonadotropins (follicle-stimulating hormone [FSH] and luteinizing hormone [LH]) and intraovarian regulators (eg, steroids, growth factors, and cytokines).

Le follicule est la structure organisée qui permet la croissance de l’ovocyte et qui amène celui-ci jusqu’à l’ovulation. Dans la majorité des cas, un follicule abrite un seul ovocyte, mais parfois, il peut en contenir plusieurs. Ce type de follicule polyovocytaire est observé chez de très nombreuses espèces de mammifères et leur fréquence est ...

Activation of follicle development: the primordial follicle
Theriogenology, 2001Investigations of primordial follicle formation and growth are fundamental to our understanding of female gamete production. In all mammalian females the full complement of oocytes is established during fetal development. This store of primordial follicles is not renewable and serves the entire reproductive life span of the adult.

Follicle-Stimulating Hormone and Advanced Follicle Development in the Human
Archives of Medical Research, 2001The great majority of human oocytes is destined to undergo atresia. Only follicles able to respond to stimulation by follicle-stimulating hormone (FSH) will enter the final stage of development and ovulate. While the role of FSH in early follicle development is unclear, late follicular development is FSH-dependent.

Norepinephrine in Graafian Follicles Is Depleted by Follicle-Stimulating Hormone*
Endocrinology, 1982The purpose of the present study was to measure norepinephrine (NE) in Graafian follicles and correlate changes in its concentration with circulating gonadotropins secreted endogenously or administered exogenously. Graafian follicles were removed from the ovaries of adult cycling rats. The follicles were pooled in groups of 10-13, and NE was determined

Fertility and Sterility, 1986
Four patients who had no oocytes retrieved during an IVF cycle were studied in an attempt to identify predictors of such an occurrence and suggestions for its cause. All 30 follicles aspirated in five cycles in these four women yielded no oocytes. One patient had two cycles that produced no eggs. The empty follicle syndrome may represent a new syndrome

Archives of Dermatology, 1973
To the Editor.— In theArchives(104:431-433, 1971) Drs. D. J. Pirozzi and P. R. Gross refer to the perifollicular disposition of xanthomas in a patient affected with type IV hyperlipoproteinemia as an entity not previously reported. In our department we have observed three patients with similar lesions and the same metabolic disorder of lipids and ...

Hair follicle predetermination
Journal of Cell Science, 2001Recent genetic and molecular studies of hair follicle (HF) biology have provided substantial insight; however, the molecular data, including expression patterns, cannot be properly appreciated without an understanding of the basic cellular rearrangements and interactions that underpin HF cyclic transformations.

Biology of reproduction, 2001
Follicle selection occurs throughout an adult female's reproductive life, with selected, dominant follicle(s) developing to the preovulatory stage whereas the remaining, subordinate follicles within the growing cohort instead undergo atresia and die. To date, most research into follicle dominance has concentrated on its endocrine regulation, although ...
