Oxidative stress in oocyte aging and female reproduction

Journal of Cellular Physiology, 2021
In a healthy body, reactive oxygen species (ROS) and antioxidants remain balanced. When the balance is broken toward an overabundance of ROS, oxidative stress appears and may lead to oocyte aging.

Metabolic co-dependence of the oocyte and cumulus cells: essential role in determining oocyte developmental competence.

Human Reproduction Update, 2020
BACKGROUND Within the antral follicle, the oocyte is reliant on metabolic support from its surrounding somatic cells. Metabolism plays a critical role in oocyte developmental competence (oocyte quality).

Melatonin supplementation during in vitro maturation of oocyte enhances subsequent development of bovine cloned embryos

Journal of Cellular Physiology, 2019
Oocyte quality, which is directly related to reprogramming competence, is a major important limiting factor in animal cloning efficiency. Compared with oocytes matured in vivo, in vitro matured oocytes exhibit lower oocyte quality and reprogramming ...

Follicular fluid exosomes act on the bovine oocyte to improve oocyte competence to support development and survival to heat shock.

Reproduction, Fertility and Development, 2019
Addition of follicular fluid to oocyte maturation medium can affect cumulus cell function, increase competence of the oocytes to be fertilised and develop to the blastocyst stage and protect the oocyte from heat shock.
