Effect of high dose gonadotropin stimulation on follicular atresia through light chain 3B and voltage dependent anion channel 2

Journal of Human Reproductive Sciences, 2022
Background: Follicle development takes place under the control of hormonal and environmental stimuli. It suggested that to improve in vitro fertilisation outcomes in poor responders increasing gonadotropin doses be used.

Dynamic Expression and Regulation of Urotensin I and Corticotropin-Releasing Hormone Receptors in Ovary of Olive Flounder Paralichthys olivaceus

Frontiers in Physiology, 2019
Urotensin I (UI), a fish corticotropin-releasing hormone (CRH) like peptide, has been found throughout vertebrate species that has great effects on adaptive physiology comprising stress-related responses, and osmotic regulation by binding with CRH type I

Association between Diethylhexyl Phthalate Exposure with Folliculogenesis and Ovarian Steroidogenesis: A Systematic Review and Meta-Analysis

Clinical and Experimental Obstetrics & Gynecology, 2023
Background: Environmental endocrine disruptor-diethylhexyl phthalate (DEHP) or its active metabolites-mono(2-ethylhexyl) phthalate (MEHP) has the greatest endocrine disrupting potency.

Unraveling ovarian histology: The key morphological aspects that spur the development of the Fossa ovarii in equine

The Anatomical Record, EarlyView.
Abstract The equine ovary exhibits unique structural and developmental features that distinguish it from those of other domestic species, including the presence of an ovulation fossa and an inversion of cortical and medullary layers. This study aimed to investigate the morphostructural development of the equine fetal ovary, with particular emphasis on ...

Follicle Stimulating Hormone in Cattle Breeding: Fundamentals, Innovations, and Scope

Animal Research and One Health, EarlyView.
FSH is crucial in cattle reproduction, with exogenous administration enhancing breeding and embryo production. Recombinant FSH offers advantages over pituitary‐extracted variants, including fewer injections, reduced stress, and safer production. These innovations improve breeding efficiency, optimize reproductive outcomes, and contribute to sustainable

Intraovarian Control of Early Folliculogenesis [PDF]

Endocrine Reviews, 2015
Although hormonal regulation of ovarian follicle development has been extensively investigated, most studies concentrate on the development of early antral follicles to the preovulatory stage, leading to the successful use of exogenous FSH for infertility treatment.

Ovarian stimulation by promoting basal follicular growth

Reproductive Biology and Endocrinology
Background Most methods of ovarian stimulation rely on gonadotropin modulation. However, abnormal anti-Müllerian hormone concentrations are frequent in infertility, suggesting that defects in the gonadotropin-independent period of folliculogenesis ...

Extracellular vesicles from endothelial progenitor cells promote thyroid follicle formation

Journal of Extracellular Vesicles, 2018
Organogenesis is a complex and dynamic process requiring reciprocal communication between different cell types. In the thyroid, thyrocyte progenitors secrete the angiocrine factor, VEGFA, to recruit endothelial cells. In return, endothelial cells promote

Duck Orbivirus and Egg Production: A Newly Identified Duck Orbivirus Is the Etiological Agent of Egg Production Decline in Chinese Breeder Ducks

Animal Research and One Health, EarlyView.
Field samples from breeder duck farms with egg‐production decline were subjected to viral detection, genome sequencing, and virus isolation. Experimental infection demonstrated that duck orbivirus (DORV) causes a significant and persistent reduction in egg production in breeder ducks.
