Clinical and Experimental Reproductive Medicine, 2012 Empty follicle syndrome (EFS) is a condition in which no oocytes are retrieved after an apparently adequate ovarian response to stimulation and meticulous follicular aspiration. EFS can be classified into 'genuine' and 'false' types according to hCG levels. It is a rare condition of obscure etiology. The existence of genuine EFS has been questioned and

Regulation of follicle waves to maximize fertility in cattle.
Journal of reproduction and fertility. Supplement, 2019 Cattle have recurrent follicular waves every 7-10 days in most physiological situations; an FSH increase is associated with emergence of the wave and LH pulse frequency determines the fate of the dominant follicle.

Granulosa Cell Apoptosis in the Ovarian Follicle—A Changing View
Frontiers in Endocrinology, 2018 Recent studies challenge the previous view that apoptosis within the granulosa cells of the maturing ovarian follicle is a reflection of aging and consequently a marker for poor quality of the contained oocyte.

Gonadotrophic control of follicle growth in the ewe.
Journal of reproduction and fertility. Supplement, 2019 Preovulatory follicle growth in the ewe is dependent on FSH although no precise relationship appears to exist between plasma concentrations of FSH and the number of preovulatory follicles which develop or ovulation rate. This may be related to a hitherto

Bioengineering the Hair Follicle [PDF]
Organogenesis, 2007 The hair follicle develops from the primitive embryonic epidermis as a result of complex epithelial-mesenchymal interactions. The full follicle, consisting of epithelial cylinders under control of a proximal lying mesenchymal papilla, grows in cycles giving rise to a new hair shaft during each cycle.
