The Effect of Radiation Emitted by Cell Phone on The Gelatinolytic Activity of Matrix Metalloproteinase-2 and -9 of Mouse Pre-Antral Follicles during In Vitro Culture [PDF]
Cell Journal, 2019 Objective: The unfavorable effects of electromagnetic radiation (EMR) emitted by the cell phone on reproduction health are controversial. Metalloproteinases play a vital role in ovarian follicle development.

Spontaneous luteinization of antral marmoset follicles in vitro [PDF]
Molecular Human Reproduction, 2000 Large non-luteinized follicles of the marmoset monkey were cultured for up to 96 h in the presence of substances that are known to induce luteinization, i.e. LH, transforming growth factor (TGF)-beta and cyclic AMP. The state of the basal lamina, and the expression of connexin-43, alpha(2) integrin subunit and TGF-beta receptor type II (TbetaR-II) were

Biology, 2023 In Phodopus sungorus, the relationship between pituitary adenylate cyclase-activating polypeptide (PACAP) and its receptor (PAC1R), follicle-stimulating hormone (FSH), and follicle development remains unclear. In this study, we found that the development

Frontiers in Endocrinology, 2018 Androgen production by the ovary is an essential requirement for normal cyclical secretion of estradiol but its physiological role extends to important actions on both preantral and antral follicle development, including promotion of granulosa cell ...

Follicle Structure Influences the Availability of Oxygen to the Oocyte in Antral Follicles [PDF]
Computational and Mathematical Methods in Medicine, 2011 The ability of an oocyte to successfully mature is highly dependent on intrafollicular conditions, including the size and structure of the follicle. Here we present a mathematical model of oxygen transport in the antral follicle. We relate mean oxygen concentration in follicular fluid of bovine follicles to the concentration in the immediate vicinity ...

Reproductive Medicine and Biology, 2021 Background The process of follicle development is tightly regulated by pituitary gonadotropins (follicle‐stimulating hormone [FSH] and luteinizing hormone [LH]) and intraovarian regulators (eg, steroids, growth factors, and cytokines).

Model of antral follicle dynamics during the 5-day cycle in rats based on measurement of antral follicle inflow [PDF]
Reproduction, 1993 Antral follicles were counted in ovaries from young adult Wistar rats, collected on the 5 days of the ovarian cycle. Follicles were classified as healthy, early atretic or late atretic and divided into five volume classes. From these data, a model was developed in which the inflow of healthy follicles into the various size classes was quantified.

Animal, 2015 The follicle destiny towards ovulation or atresia is multi-factorial in nature and involves outcries, paracrine and endocrine factors that promote cell proliferation and survival (development) or unchain apoptosis as part of the atresia process.
