Hyaluronan and proteoglycans in ovarian follicles [PDF]
Human Reproduction Update, 1999 Proteoglycans are macromolecules formed by a protein backbone to which one or more glycosaminoglycan side chains are co-valently attached. They can be secreted by the cells, retained at the cell surface, or stored in intracellular vacuoles. Hyaluronan is an extremely long glycosaminoglycan which, at variance with other glycosaminoglycans, is released ...

Preantral follicle population and distribution in the horse ovary
Reproduction and Fertility, 2022 Characterization of the ovarian preantral follicle population is a necessary step to improve understanding of folliculogenesis and ovarian physiology. Therefore, in the present study, the preantral follicle population in the equine ovary in young and old

In vitro ovarian follicle growth: a comprehensive analysis of key protocol variables†
Biology of Reproduction, 2020 Folliculogenesis is a complex process that requires integration of autocrine, paracrine, and endocrine factors together with tightly regulated interactions between granulosa cells and oocytes for the growth and survival of healthy follicles.

Inhibitory actions of Anti-Müllerian Hormone (AMH) on ovarian primordial follicle assembly. [PDF]
PLoS ONE, 2011 The current study was designed to investigate the actions of Anti-Müllerian Hormone (AMH) on primordial follicle assembly. Ovarian primordial follicles develop from the breakdown of oocyte nests during fetal development for the human and immediately ...

Germ–Somatic Cell Interactions Are Involved in Establishing the Follicle Reserve in Mammals
Frontiers in Cell and Developmental Biology, 2021 Mammalian females are born with a finite reserve of ovarian follicles, the functional units of the ovary. Building an ovarian follicle involves a complex interaction between multiple cell types, of which the oocyte germ cell and the somatic granulosa ...

Predictive factors for ovarian response in a corifollitropin alfa/GnRH antagonist protocol for controlled ovarian stimulation in IVF/ICSI cycles [PDF]
, 2015 Background This secondary analysis aimed to identify predictors of low (<6 oocytes retrieved) and high ovarian response (>18 oocytes retrieved) in IVF patients undergoing controlled ovarian stimulation with corifollitropin alfa in a gonadotropin-

Advances in human primordial follicle activation and premature ovarian insufficiency.
Reproduction, 2020 In women, the non-growing population of follicles that comprise the ovarian reserve is determined at birth and serves as the reservoir for future fertility.
