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 …

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 …

Lipids are a potential reservoir of energy for initial embryonic development before activation
of the embryonic genome and are involved in plasma membrane biosynthesis. Excessive …

Background Dynamic changes of histone posttranslational modifications are important
contexts of epigenetic reprograming after fertilization in pre-implantation embryos. Recently …

Simple Summary Early embryo development is a dynamic and orchestrated event. Oxygen
plays a fundamental role in several key biological processes necessary to sustain and …

Previous studies have discussed the importance of an optimal range of metabolic activity
during preimplantation development. To avoid factors than can trigger an undesirable …

Female infertility and pregnancy maintenance are associate with various factors, including
quantity and quality of oocytes, genital inflammation, endometriosis, and other diseases …

Development of the preimplantation embryo is reliant on nutrients present in the milieu of the
reproductive tract. While carbohydrates, amino acids, lipids, and micronutrients are often …

Understanding preimplantation embryonic development is crucial for the improvement of
assisted reproductive technologies and animal production. To achieve this goal, it is …

Incubation gas atmosphere affects the development of in vitro produced embryos. In this
study, there was examination of effects of two different oxygen (O 2) tensions (5% and 21%) …
