The role of estrogen in folliculogenesis
Molecular and Cellular Endocrinology, 1999Gonadotrophins are fundamental to the mechanisms regulating follicle status and development. Follicles in the ovary are either quiescent or committed to one of two pathways: growth or atresia. The requirement for gonadotrophins by the follicles varies with development: committed follicles grow independently of gonadotrophins (primarily FSH) until the ...

Genetics of early mammalian folliculogenesis
Cellular and Molecular Life Sciences, 2006Early ovarian folliculogenesis begins with the breakdown of germ cell clusters and formation of primordial follicles. Primordial follicles are the smallest ovarian follicle units continuously recruited to grow into primary and more advanced ovarian follicles.

International Journal of Molecular Sciences, 2021 The complex nature of folliculogenesis regulation accounts for its susceptibility to maternal physiological fitness. In obese mothers, progressive expansion of adipose tissue culminates with severe hyperestrogenism and hyperleptinemia with detrimental ...

Growth factors and folliculogenesis in polycystic ovary patients
Expert Review of Endocrinology and Metabolism, 2007 Ovarian folliculogenesis is regulated by a fine balance between endocrine and intraovarian factors. In this review, we focus on the role of growth factors in physiological folliculogenesis and in polycystic ovaries.

Newly Identified Regulators of Ovarian Folliculogenesis and Ovulation
International Journal of Molecular Sciences, 2020 Each follicle represents the basic functional unit of the ovary. From its very initial stage of development, the follicle consists of an oocyte surrounded by somatic cells.

The ovary, the female gonad, serves as the source for the germ cells as well as the major supplier of steroid sex hormones. During embryonic development, the primordial germ cells (PGCs) are specified, migrate to the site of the future gonad, and proliferate, forming structures of germ cells nests, which will eventually break down to generate the ...

The Role of the Oocyte in Folliculogenesis
Trends in Endocrinology & Metabolism, 2000Novel regulatory proteins have been identified within oocytes that are crucially involved in folliculogenesis. One of the most exciting oocyte signaling molecules is a novel member of the transforming growth factor beta (TGF-beta) superfamily, growth differentiation factor 9 (GDF-9).

Folliculogenesis ‐ The Natural Way
Australian and New Zealand Journal of Obstetrics and Gynaecology, 1994Summary: Natural cycle IVF (NIVF) arose from a wish to understand intrafollicular events in couples with unexplained infertility. Single follicle aspiration required unusual technical skill and a precise understanding of the endocrinology in the ostensibly normal cycle.

Anti-Müllerian hormone and folliculogenesis
Molecular and Cellular Endocrinology, 2005This paper reviews the role of anti-Müllerian hormone, a member of the TGF(beta) family signaling through a BMP-like pathway, in the ovary. In vivo and in vitro studies showed that AMH has an inhibitory effect on primordial follicle recruitment and it decreases the sensitivity of follicles for the FSH-dependent selection for dominance.
