Despite previous research demonstrating the benefits of including growth factors and
antioxidants to maturation medium to support embryo production, to date the effect of …

To evaluate the potential effects of melatonin on the kinetics of embryo development and
quality of blastocyst during the process of in vitro bovine embryo culture. Bovine cumulus …

Objective We increased the nuclear maturation rate of antral follicle derived oocytes by
using a pre-in vitro maturation (IVM) culture system and improved the developmental …

Simple Summary Exogenous melatonin has beneficial effects on improving cumulus
oophorus expansion; mitochondrial distribution; intracellular level of glutathione; and first …

Porcine in vitro fertilization often results in low embryo development rates compared to other
livestock species, which is often associated with either a low fertilization rate or high …

Melatonin is a universal antioxidant that improves in vitro embryo production in several
species. The aims of this study were to determine the melatonin concentration in the ovarian …

Context Heat stress has been related to reduced fertility in cattle, which may reflect damage
to developing oocytes. The deleterious effects of heat stress on oocytes may involve an …

Bovine oocytes from prepubertal donors have been used for in vitro embryo production to
decrease the generation interval. However, reduced cumulus-oocyte competence, mainly …

After reaching the metaphase II (MII) stage, unfertilised oocytes undergo a time-dependent
process of quality deterioration referred to as oocyte aging. The associated morphological …

This study evaluated the effect of epidermal growth factor (EGF) supplementation during in
vitro maturation on the meiotic status and the expression of EGF receptor (EGFr), luteinizing …
