Ovarian Stimulation and Embryo Quality
Reproductive BioMedicine Online, 2009 To study the effects of different ovarian stimulation approaches on oocyte and embryo quality, it is imperative to assess embryo quality with a reliable and objective method. Embryos rated as high quality by standardized morphological assessment are associated with higher implantation and pregnancy rates.

Effects of Ovarian Endometrioma on Embryo Quality
Fertility and Sterility, 2011The proportions of good, fair, and poor embryos in 13 women with bilateral endometriomas were compared with those of 39 women without endometriomas and were found to be similar (47.2% vs. 41.1%, 28.3% vs. 32.8%, and 24.3% vs. 26.0%, respectively). Therefore, it appears that the presence of bilateral endometriomas during IVF treatment is not associated ...

Quality control of embryo development
Molecular Aspects of Medicine, 2013Although 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, 2007It 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, 2006The 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, 2004Many 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.

Abstract Multiple pregnancy is a common complication of in vitro fertilization (IVF). Embryo quality assessment may allow us to reduce significantly the risk of multiple births by transferring two instead of three pre-embryos per cycle of IVF. So far, the assessment of embryo quality has been mainly morphological, which correlates with the chances of ...
