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.

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 ...

This chapter presents a very succinct overview of the cyclic biology of the hair follicle as it transitions from the quiescent telogen stage to the anagen stage in which hairs are actively produced before regressing through the catagen stage to telogen.

Lateralization of Ovarian Follicles
Gynecologic and Obstetric Investigation, 2014<b><i>Background/Aim:</i></b> To evaluate a possible lateralization of antral follicle count (AFC) based on the finding that endometriosis, if present, is more commonly found in the left hemipelvis. <b><i>Methods:</i></b> We evaluated the records of 6,617 baseline ultrasounds conducted at our Reproductive
