Embryo growth ratein vitro as an indicator of embryo quality in IVF cycles

Journal of Assisted Reproduction and Genetics, 1994
The 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, 1999
In 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

2014
This 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, 2008
Embryo 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.

Genetic control of embryo production and embryo quality in anther culture of Petunia

Theoretical and Applied Genetics, 1982
Anther cultures of Petunia lines and hybrids at different levels of heterozygosity were tested under similar conditions with the following results: the yield of androgenetic plants is conditionned in Petunia by two important distinct factors, i.e., yield of embryos and quality of these same embryos.
