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 ...

Embryo Quality and Freezing Tolerance: Cryopreservation of Human Embryos
2002Freezing of mammalian embryos has become part of cryobiology around 30 years ago when the embryologist-cryobiologist team of Whittingham, (1972f>) published for the first time the successful freezing of the mouse embryo leading to the birth of living young.

Noninvasive methods to assess embryo quality
Current Opinion in Obstetrics & Gynecology, 2005The present review examines recent publications concerned with the issue of the number of embryos to replace in an in-vitro fertilization cycle and in doing so concentrates on the proposed selection methods that may allow us to transfer one or two embryos.A number of techniques that will allow us to ascertain the health and viability of the embryo are ...

Embryo growth ratein vitro as an indicator of embryo quality in IVF cycles
Journal of Assisted Reproduction and Genetics, 1994The role of embryo growth rate in vitro as an isolated indicator of embryo quality in IVF was evaluated retrospectively.Comparison was made between 98 cycles (group 1), in which only embryos at a cleavage stage of two to three blastomers were transferred, and 99 cycles (group 2), in which all embryos were transferred at a cleavage stage of four or more

Characterization of a top quality embryo, a step towards single-embryo transfer
Human Reproduction, 1999In most in-vitro fertilization (IVF)/intracytoplasmic sperm injection (ICSI) programmes approximately one ongoing pregnancy in three is multiple. The need to characterize embryos with optimal implantation potential is obvious. We retrospectively examined all of 23 double transfers resulting in ongoing twins, occurring between January 1, 1996 and May 19,

ARTE: An Embryo Quality Assessment Tool
2014This paper proposes an assessment model of putative embryos for in vitro fertilization (IVF) based on a triangular norm. One of the most common difficulties of IVF treatments is multiple pregnancy. Therefore the number of embryos for transfer is of paramount importance considering the need to reduce the incidence of multiple births without compromising

[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.

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 ...
