Quality control of embryo development

Molecular Aspects of Medicine, 2013
Although in recent years we have seen an undeniable improvement in the field of reproductive biology and medicine, the efficiency of in vitro fertilization (IVF) procedures remains relatively low, ranging from 4% to 40% depending on the patient's age. It is believed that this is in a large part caused by inaccurate assessment of embryo quality prior to

Quantification of embryo quality by respirometry

Theriogenology, 2007
It is generally accepted that assessment of embryo metabolism, in particular oxygen consumption, may improve embryo selection by identifying the embryos with higher developmental competence. Several methods have been employed to measure embryonic oxygen consumption, but most of them were detrimental to subsequent embryo development.

Contribution of the oocyte to embryo quality

Theriogenology, 2006
The ability of a bovine embryo to develop to the blastocyst stage, to implant and to generate a healthy offspring is not a simple process. To clarify the importance of the contribution of the oocyte to the embryo quality, it is important to define more precisely the different types of competence expressed by oocytes.

Production and Quality of Bovine Oocytes and Embryos

Veterinary Research Communications, 2004
Many factors influence the efficiency of the in vitro embryo production technology in cattle but the most important are the physiological conditions of the donor and the culture protocols for oocyte maturation and fertilization and for embryo culture from zygote to blastocyst.
