Metabolism and ATP levels within the oocyte and adjacent cumulus cells are associated
with quality of oocyte and optimal development of a healthy embryo. Lipid metabolism …

In vitro follicle growth and oocyte maturation still has a series of limitations, since not all
oocytes matured in vitro have the potential to develop in viable embryos. One of the factors …

Vitrification of oocytes has been shown to be closely associated with increased levels of
reactive oxygen species (ROS) and apoptotic events. However, little information is available …

The purpose of this study was to investigate the changes in mitochondria in porcine MII-
stage oocytes after open pulled straw (OPS) vitrification and to determine their roles in …

Poor oocyte quality is responsible for female infertility. Multiple studies have been carried
out to find supplements to enhance oocyte quality and mitigate infertility problems. l …

Fatty acid b-oxidation (FAO) is essential for oocyte maturation in mice. The objective of this
study was to determine the effect of etomoxir (a FAO inhibitor; 100 mM), carnitine (1 mM) …

STUDY QUESTION Does the use of a new cryoprotectant agent (CPA) exchange protocol
designed to minimize osmotic stress improve oocyte or zygote vitrification by reducing …

Cryopreservation techniques for mammalian oocytes and embryos have rapidly progressed
during the past two decades, emphasizing their importance in various assisted reproductive …

Oocyte vitrification is crucial for livestock reproduction, germplasm conservation, and human-
assisted reproduction, but the overabundance of lipids is highly detrimental to oocyte …

STUDY QUESTION How does l-carnitine (LC) supplementation during vitrification and in
vitro maturation (IVM) of germinal vesicle stage (GV)–oocytes improve the developmental …
