In brief Reactive oxygen species are generated throughout the pre-implantation period and
are necessary for normal embryo formation. However, at pathological levels, they result in …

The process of embryonic development is crucial and radically influences preimplantation
embryo competence. It involves oocyte maturation, fertilization, cell division and blastulation …

Oxidative stress is involved in the aetiology of defective embryo development. Reactive
oxygen species (ROS) may originate from embryo metabolism and/or embryo surroundings …

Significance: To improve the outcomes of in vitro culture of human oocytes and embryos, the
dynamic balance and roles of reactive oxygen species (ROS) in folliculogenesis and embryo …

Reactive oxygen species (ROS) are generated as by-products of aerobic respiration and
metabolism. Mammalian cells have evolved a variety of enzymatic mechanisms to control …

Oocytes and preimplantation embryos require careful regulation of the redox environment
for optimal development both in vivo and in vitro. Reactive oxygen species (ROS) are …

Reactive oxygen species (ROS) are oxygen-containing molecules which are reactive in
nature and are capable of independent existence in the body. ROS comprise mostly of free …

The cellular components of the human reproductive system are as vulnerable as other cells
to the potential detrimental effects of reactive oxygen species (ROS). Antioxidant protection …

Oxidative stress (OS) due to an imbalance between reactive oxygen species (ROS) and
antioxidants has been established as an important factor that can negatively affect the …

Free radicals, once the preserve of chemists, are now recognized as playing a central role in
many biological systems. They are formed as an inevitable by-product of aerobic respiration …
