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 ...

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.

Pregnancy sickness and embryo quality
Trends in Ecology & Evolution, 2002Nausea and vomiting are routine features of early pregnancy in humans. But are they adaptive or pathological? Several lines of evidence suggest that they protect mothers and developing embryos from dietary mutagens and pathogens. Nausea and vomiting in pregnancy (NVP) coincide with the vulnerable period of embryogenesis, are associated with food ...

[Embryo quality and selection].
Journal de gynecologie, obstetrique et biologie de la reproduction, 2008Embryo quality is routinely evaluated based on morphological and kinematic criteria, but it should also be founded on clinical and biological data from the ovulation induction treatments and the data from the SPZ test, with, if necessary, their genetic analysis. Zygote quality evaluation is based on the zygote score or the P0 profiles.

Influence of the male on embryo quality
Theriogenology, 2007Early pregnancy failure or loss (EPL) represents a major source of wastage and inefficiency in livestock production systems. Although successful embryo development is dependent upon genetic and epigenetic contributions from both the male and female, potential adverse male affects on embryo quality and development are probably often underestimated.
