Ovarian Follicle Development in Ascidians

Zoological Science, 2023
Ovarian follicle development is an essential process for continuation of sexually reproductive animals, and is controlled by a wide variety of regulatory factors such as neuropeptides and peptide hormones in the endocrine, neuroendocrine, and nervous systems.

Tracking Follicle Cell Development

2023
Somatic follicle cells are critical support cells for Drosophila oogenesis, as they provide signals and molecules needed to produce a mature egg. Throughout this process, the follicle cells differentiate into multiple subpopulations and transition between three different cell cycle programs to support nurse cell and oocyte development.

Follicle Development in Mares

Reproduction in Domestic Animals, 2008
ContentsThe mare provides a unique experimental model for studying follicle development in monovular species. Development of antral follicles in horses is characterized by the periodic growth of follicular waves which often involve the selection of a single dominant follicle.

Ovarian control of follicle development

American Journal of Obstetrics and Gynecology, 1995
A variety of ovarian autocrine and paracrine factors may modulate folliculogenesis and steroid production. The developmental program that leads to the production of a dominant follicle involves a precise quantitative and temporal pattern of expression of a large number of genes.

Obesity accelerates ovarian follicle development and follicle loss in rats

Metabolism, 2014
Studies have shown that excess body fat negatively affects reproductive functions in females. However, whether obesity affects the ovarian follicle development and ovarian lifespan and the underlying mechanism has not been well elucidated. The aim of the present study was to investigate the association between obesity and ovarian follicle development ...

Follicle-Stimulating Hormone and Advanced Follicle Development in the Human

Archives of Medical Research, 2001
The 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.

In Vitro Development of Ovarian Follicles

Seminars in Reproductive Medicine, 2011
Tissue banking of ovarian material is being increasingly offered to a variety of patients as a means of fertility preservation. This tissue comprises thin cortical surface biopsies that contain predominantly primordial follicles, and currently the only option to restore fertility is by transplantation.

Gonadotropin requirements of the developing follicle

Fertility and Sterility, 1995
To evaluate follicular FSH and LH requirements during suppression of endogenous gonadotropins with the GnRH antagonist Nal-Glu and whether LH-like activity could be supplied by administering subcutaneous hCG.Randomized clinical trial.Thirty-two normally cycling females in the late follicular phase (dominant follicle mean diameter > or = 14 mm).Twelve ...
