High multiple pregnancy rates after double embryo transfers in human: a retrospective cohort study

Reproduction and Fertility
To improve clinical outcomes of human medically assisted reproduction, the transfer of multiple embryos is frequently performed. This leads to high rates of multiple pregnancies.

DNA fragmentation index (DFI) as a measure of sperm quality and fertility in mice. [PDF]

, 2020
Although thousands of genetically modified mouse strains have been cryopreserved by sperm freezing, the likelihood of cryorecovery success cannot be accurately predicted using conventional sperm parameters.

Embryo Aggregation in Pig Improves Cloning Efficiency and Embryo Quality

PLOS ONE, 2016
Dans cette étude, nous avons analysé les effets de l'agrégation d'embryons clonés sur le développement embryonnaire in vitro et la qualité de l'embryon en mesurant le diamètre et le nombre de cellules du blastocyste, les niveaux de fragmentation de l'ADN et l'expression des gènes associés à la pluripotence, à l'apoptose, au trophoblaste et à la ...

Undernutrition affects embryo quality of superovulated ewes [PDF]

Zygote, 2013
SummaryTo determine the effect of undernutrition on embryo production and quality in superovulated sheep, 45 ewes were allocated into two groups to be fed diets that provided 1.5 (control, C; n = 20) or 0.5 (low nutrition, L; n = 25) times daily requirements for maintenance, from oestrous synchronization with intravaginal sponges to embryo collection ...

Cellular Fragments in the Perivitelline Space Are Not a Predictor of Expanded Blastocyst Quality

Frontiers in Cell and Developmental Biology, 2021
The presence of cellular fragments in the perivitelline space is a commonly used parameter to determine quality before transfer of in vitro produced (IVP) embryos. However, this parameter is difficult to assess after blastocyst expansion.

Embryo culture in presence of oviductal fluid induces DNA methylation changes in bovine blastocysts [PDF]

, 2017
During the transit through the oviduct, the early embryo initiates an extensive DNA methylation reprogramming of its genome. Given that these epigenetic modifications are susceptible to environmental factors, components present in the oviductal milieu ...

Efficient Bayesian-based Multi-View Deconvolution

, 2014
Light sheet fluorescence microscopy is able to image large specimen with high resolution by imaging the sam- ples from multiple angles. Multi-view deconvolution can significantly improve the resolution and contrast of the images, but its application has ...

Effect of endometrial thickness and embryo quality on live-birth rate of fresh IVF/ICSI cycles: a retrospective cohort study

Reproductive Biology and Endocrinology, 2020
Background Successful implantation and delivery require both the functional embryo and receptive endometrium in assisted reproductive technology (ART) cycles. However, little is known about embryo-endometrial interaction on live-birth.
