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 ...

Cumulus mass maintains embryo quality
Fertility and Sterility, 1994To determine if co-culture of early stage embryos with their own cumulus mass improves embryo quality.Before insemination, cumulus masses along with cumulus matrices were separated from the oocytes surrounded by a few remaining cumulus cells. Fourteen hours after insemination, fertilized oocytes were each placed onto the cumulus cells, and matrix and ...

Ovarian stimulation and embryo quality
Reproductive BioMedicine Online, 2009To 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.

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.

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 ...

Human reproduction (Oxford, England), 1995
To determine the effect of cryopreservation on embryo quality and the pregnancy potential of embryos, donated oocytes from the same donor (n = 24) were randomly allocated, with subsequent transfer to two or more different ovum recipients resulting in at least one fresh and one frozen embryo transfer cycle from the same cohort of oocytes.
