OBJECTIVE: The manipulation of gametes and embryos in an in vitro environment when
performing assisted reproductive techniques (ART) carries the risk of exposure of these cells …

Many factors affect development of mammalian preimplantation embryos in vitro. It is well
known that in vitro development of bovine embryos is highly affected by culture condition …

OBJECTIVE: To evaluate, using time-lapse monitoring, the temporal influence of culture in
5% O2 or 20% O2 on human embryonic development. DESIGN: Retrospective cohort study …

Gametes and embryos are natural sources of free radicals. When manipulated in vitro during
assisted reproductive techniques, these cells run the risk of generating and being exposed …

BACKGROUND The potentially damaging effect of free O2 radicals to cultured embryos may
be reduced by adding scavengers to the culture media or by reducing the incubator O2 …

Contents Recent advances in new technologies to produce cloned and genetically modified
pigs involve manipulating oocytes and/or embryos in vitro. Although a great deal of progress …

OBJECTIVE: To investigate birth rates with two oxygen (O2) concentrations in blastocyst
culture. DESIGN: Randomized trial. SETTING: Private in vitro fertilization (IVF) clinic …

The optimum oxygen tension for culturing mammalian embryos has been widely debated by
the scientific community. While several laboratories have moved to using 5% as the value for …

To realize the full potential of human embryonic stem cells (hESCs), it is important to
develop culture conditions that maintain hESCs in a pluripotent, undifferentiated state. A low …

Simple Summary In vitro embryo production (IVEP) is a technology that is widely used in the
field of reproductive biology. The first and most important step of IVEP is termed in vitro …
