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.

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.

Folliculogenesis ‐ The Stimulated Way
Australian and New Zealand Journal of Obstetrics and Gynaecology, 1994Summary: The initial techniques of stimulating follicular development in the anovulatory woman involved the use of human pituitary gonadotropin (hPG) and thus replaced the function of the pituitary gland. Despite extreme care with administration of hPG and extensive monitoring to assess the ovarian response, ovarian hyperstimulation and multiple ...

The IGF family and folliculogenesis
Journal of Reproductive Immunology, 1998The process of ovarian follicular development is a long and arduous one, marked by dramatic proliferation and differentiation of both the somatic and germ cell elements. To a large extent, this explosive agenda is under the control of conventional endocrine principles, involving hormones such as pituitary gonadotropins and ovarian steroids. Importantly,

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 ...

Folliculogenesis in Polycystic Ovaries
2008Polycystic ovary syndrome (PCOS) is the commonest cause of anovulatory infertility. Anovulation in PCOS is characterized by arrested growth of antral follicles. Although arrested antral follicle growth probably reflects the abnormal endocrine environment in PCOS (and, particularly the effect of hyperinsulinemia), there is increasing evidence of ...

Folliculogenesis in the Primate Ovarian Cycle
Endocrine Reviews, 1981MUCH MORE is known about ovarian function in small mammals, especially laboratory rodents, than about the factors regulating cyclic ovarian function in primates. However, recent results, including our own, have enhanced the understanding of ovarian function in primates, bringing new and significant findings that now justify an assembly of knowledge on ...

[Folliculogenesis and regulating factors].
Nihon rinsho. Japanese journal of clinical medicine, 1998Folliculogenesis and steroid production are the bases of fertility in the female mammal. Follicle stimulating hormones (FSH) plays an essential role in this process. It is clear that a variety of ovarian autocrine and paracrine factors can regulate this FSH receptor signal. In the past decade, it is established that growth factors, particularly insulin

[Intraovarian regulators of folliculogenesis].
Uspekhi fiziologicheskikh nauk, 2010The review summarizes information about the intraovarian modulators of folliculogenesis. Consistently described auto-and paracrine factors and mechanisms involved in the regulation of follicular development from the entry in the growth of primordial follicles before ovulation of the dominant follicle.
