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

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

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.

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 ...

Embryology of the hair follicle
Early Human Development, 1991A study of hair follicle development has enabled us to differentiate four stages by relating them to corresponding gestation ages. Stage I of the hair bud is characterized by an epiblastic proliferation penetrating the subjacent mesenchyma at the extremity of which mesenchymal cells accumulate.

Hair has many useful biologic functions, including protection from the elements and dispersion of sweat-gland products (e.g., pheromones). It also has psychosocial importance in our society, and patients with hair loss (alopecia) (Table 1) or excessive hair growth often suffer tremendously.

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.

Influence of the dominant follicle on oocytes from subordinate follicles
Theriogenology, 1999As the oocyte grows within the follicle, a number of factors influence its health and developmental competence. These factors include follicle size, day of estrous cycle, level of atresia and influence of other follicles such as the dominant follicle. Follicles were dissected from ovaries of synchronized dairy cows on four days during the estrous cycle,

Acne is a dermatosis that is strictly confined to hair follicles. It cannot be understood without a detailed knowledge of the structure of the pilosebaceous unit.

The American Journal of Dermatopathology, 1984
A case of a 5-year-old child with a rare nevus of a hair follicle is reported. Histologically it was characterized by many hair follicles within the dermis at the same level of maturation. This nevus must be differentiated from other hamartomas of hair follicles and from Becker's nevus.
