The role of zinc in follicular development

Molecular Biology Reports, 2023
Follicles consist of specialized somatic cells that encase a single oocyte. Follicle development is a process regulated by a variety of endocrine, paracrine, and secretory factors that work together to select follicles for ovulation. Zinc is an essential nutrient for the human body and is involved in many physiological processes, such as follicle ...

Diet and follicular development

The American Journal of Clinical Nutrition, 1984
In Caucasian women, the length of the menstrual cycle is 28 days with a SD of 3.9 days. Many factors including diet modify menstrual periodicity. We have determined the effect of a meatless vegetarian diet in Caucasian women on the length of the menstrual cycle and the episodic and luteinizing releasing hormone-stimulated release of luteinizing hormone.

Follicular Development In Vitro

Seminars in Reproductive Medicine, 2000
There has been tremendous interest in recent years in the culture of oocytes and follicles. Although much of the research using follicle culture aims to increase understanding of the regulation of follicle development, an important goal has been to develop a method that will eventually allow maturation of human oocytes from the primordial follicle to ...

GONADOTROPHIN CONTROL OF FOLLICULAR DEVELOPMENT

Clinical Endocrinology, 1985
SUMMARYIn order to investigate the endocrine requirements for induction of follicle maturation, ovulation and luteal function we have measured plasma LH and FSH concentrations in 109 cycles induced by treatment with LHRH in 25 women with amenorrhoea of diverse aetiology. The major clinical and endocrine subgroupings were polycystic ovarian disease (PCO)

Follicular Development and Apoptosis

2002
More than 99.9% of the ovarian follicles present at birth never reach ovulation. The most common fate of follicles is instead to undergo atresia, which has been shown to be mediated by a highly organised type of cell death called apoptosis or programmed cell death (Hsueh et al. 1994; Billig et al. 1996; Kaipia and Hsueh 1997).

Development of the ovarian follicular epithelium

Molecular and Cellular Endocrinology, 1999
A lot is known about the endocrine control of the development of ovarian follicles, but a key question now facing researchers is which molecular and cellular processes take part in control of follicular growth and development. The growth and development of ovarian follicles occurs postnatally and throughout adult life.

Follicular development: the role of the follicular microenvironment in selection of the dominant follicle

Animal Reproduction Science, 2004
The importance of endocrine signals in the regulation of follicular development has long been recognized. However, the follicular microenvironment also plays a critical role in determining follicular fate. This review summarizes our studies on the role of the intrafollicular IGF system in selection of the dominant follicle (DF) in cattle.

Role of autophagy in follicular development and maintenance of primordial follicular pool in the ovary

Journal of Cellular Physiology, 2021
AbstractThe reproductive life span of the organism mainly depends on follicular development that maintains the primordial follicle pool in the cohort of follicles within the ovary. The total count of primordial follicles decreases with age due to ovulation and follicular atresia.

Induction of multiple follicular development for IVF

British Medical Bulletin, 1990
It is now accepted, almost universally, that multiple follicular development is a pre-requisite for a successful assisted conception programme. The reasons for this are based on abundant clinical evidence from the major IVF and GIFT centres of the world indicating the benefits of having multiple gametes available for transfer.

Role of Macrophages in Ovarian Follicular Development

Hormone Research, 2008
The effects of macrophages on granulosa cell proliferation were examined using gonadotropin-primed immature female rats and osteopetrotic (op/op) mice, a model defective in monocyte-macrophage lineage cells. Macrophages were found in the follicles at various developmental stages in rats and mice.
