Female reproductive decline is determined by remaining ovarian reserve and age. [PDF]

PLoS ONE, 2014
The early decline and loss of female fertility in humans and other species represents an evolutionary paradox. Despite being born with a vast stock of oocytes, females encounter an exhaustion of ovarian reserve and sterility half way through their ...

Dynamic genome-scale cell-specific metabolic models reveal novel inter-cellular and intra-cellular metabolic communications during ovarian follicle development

BMC Bioinformatics, 2019
Background The maturation of the female germ cell, the oocyte, requires the synthesis and storing of all the necessary metabolites to support multiple divisions after fertilization.

Lipid Identification and Transcriptional Analysis of Controlling Enzymes in Bovine Ovarian Follicle

International Journal of Molecular Sciences, 2018
Ovarian follicle provides a favorable environment for enclosed oocytes, which acquire their competence in supporting embryo development in tight communications with somatic follicular cells and follicular fluid (FF). Although steroidogenesis in theca (TH)

Ovarian antral follicle number and the amount of gonadotropin used in ovarian stimulation in polycystic ovarian patients.

مجلة كلية الطب, 2011
Background: Polycystic ovary syndrome is the most common cause of anovulation, and the number of antral follicles is of great importance in determining ovarian reserve, so identification of patients with diminished ovarian reserve help in choosing ...

Fractionation of Ovarian Follicles and in vitro Oocyte Maturation and Ovulation Assay of Ciona intestinalis Type A

Bio-Protocol, 2020
Ascidians are the closest living relatives of vertebrates (Delsuc et al., 2006; Satoh et al., 2014) and are important for the evolutionary study of the ovarian follicle development including oocyte maturation and ovulation.

CCDC41 Drives Oocyte Meiotic Progression by Promoting Rab11a/Rab7‐Positive Vesicle Fusion with Target Membranes

Advanced Science, EarlyView.
CCDC41 is essential for meiotic maturation in mouse oocytes through regulating Rab7‐positive endosomes fusion with lysosomes and Rab11a‐positive vesicle fusion with the plasma membrane. Abstract Coiled‐coil domain‐containing protein 41 (CCDC41), a core component of centriolar distal appendages involved in centriole assembly and ciliary vesicle docking,
