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

The preimplantation mammalian embryo from different species appears sensitive to the
environment in which it develops, either in vitro or in vivo, for example, in response to culture …

Porcine in vitro production (IVP) systems, including in vitro maturation (IVM) and in vitro

In the first of two experiments investigating the effect of dietary urea on the survival and
metabolism of ovine embryos, 30 Border Leicester× Scottish Blackface ewes received a …

Up to 40% of cattle embryos die within 3 weeks of fertilization while they are nutritionally
dependent on the maternal environment provided by the oviduct and uterine fluids for their …

Amino acids are essential components of media utilized to culture fertilized human eggs to
the blastocyst stage in vitro. Use of such media has led to a significant increase in the …
