To determine effects of maternal diet on in vitro fertilization (IVF) and early embryonic
development, ewes (n= 48) were divided into control, overfed (ad libitum feeding), and …

Medically assisted reproductive technologies, such as in vitro embryo production, are
increasingly being used to palliate infertility. Eggs are produced following a hormonal …

This study investigated effects of hexoses, fetal calf serum (FCS), and phenazine ethosulfate
(PES) during the culture of bovine embryos on blastocyst development and survival after …

Using complex media containing serum and somatic cells, pregnancy rates following
transfer of single, day 7 advanced-stage blastocysts approached 60%, while pregnancy …

The nutrient requirements and metabolic pathways used by the developing embryo
transition from predominantly pyruvate during early cleavage stages to glucose at the …

Protein content was measured in zona‐free bovine oocytes and pre‐elongation stage
embryos, following in vitro maturation, fertilisation, and then culture in Synthetic Oviduct …

Despite recent progress, we are still far from understanding how, when and where
environmental stressors disturb key epigenetic mechanisms. Thus, identifying the original …

In vitro production of embryos from domestic animals is used to augment conventional
genetic improvement programmes in agriculture and to facilitate advances in gene transfer …

Although the potential use of reproductive biotechnologies for safeguarding endangered
wildlife species is undoubted, practical efforts have met with limited success to date. In those …

This review examines current understanding of mammalian mitochondria and mitochondrial
DNA in the light of new reproductive technologies. Mitochondria are central to ageing …
