Multiple pregnancies lead to complications and induce high costs. The most successful way to decrease multiple pregnancies in IVF is to transfer only one embryo, which might reduce the efficacy of treatment. The objective of this review is to determine which embryo-transfer policy is most cost-effective: elective single-embryo transfer (eSET) or double-embryo transfer (DET). Several databases w...

BACKGROUND IVF is limited by low success rates and an unacceptably high multiple pregnancy rate. These outcomes would be improved significantly if a single embryo of high viability could be replaced in each treatment cycle, but widespread acceptance of such a policy is hindered by the lack of predictive factors for embryo selection. We have conducted a retrospective clinical study of a novel no...

The recent development of genomic selection induces dramatic changes in the way genetic selection schemes are to be conducted. This review describes the new context and corresponding needs for genomic based selection schemes and how reproductive technologies can be used to meet those needs. Information brought by reproductive physiology will provide new markers and new improved phenotypes that ...

Although progress was made in in vitro fertilization (IVF) techniques, the majority of embryos transferred fail to implant. Morphology embryo scoring is the standard procedure for most of IVF centres for choosing the best embryo, but remains limited since even the embryos classified as "top quality" may not implant. As it has been shown that i) CD146 is involved in embryo implantation and ii) m...

Failure to select a viable embryo in a given fertility treatment cycle limits the success rates of current procedures. Fertility clinics rely on a morphological assessment of embryo appearance at a few distinct timepoints during development to pick a viable embryo for transfer. However, embryo development is a very dynamic process and critical stages between observations go unnoticed. This docu...

Assisted reproductive technology (ART) has been recognized for its success in treating infertility, a condition that affects 15 percent of couples in the United States. The most popular option is in vitro fertilization (IVF), which relies on embryo culture, selection, and transfer for implantation, with the ultimate aim of pregnancy. Previous embryo selection methods relied on morphological fac...

Wheat is one of the Neolithic founder crops domesticated ~10 500 years ago. Following the domestication episode, its evolution under domestication has resulted in various genetic modifications. Grain weight, embryo weight, and the interaction between those factors were examined among domesticated durum wheat and its direct progenitor, wild emmer wheat. Experimental data show that grain weight h...

Assisted human reproduction is characterized by a high variability in results regarding pregnancy and birth rates. In fact, in a cohort of fertilized oocytes from the same stimulation cycle, the development rate varies drastically, even though produced at the same time and under similar conditions. This variability results in large differences in implantation potential of human embryos develope...

This review addresses issues regarding the need in the in vitro fertilization (IVF) field for further predictive markers enhancing the standing embryo selection criteria. It aims to serve as a source of defining information for an audience interested in factors related to the wide range of multiple roles played by cell adhesion molecules (CAMs) in several aspects of IVF ultimately associated wi...
