Hyaluronan and Hyaluronidase, which is better for embryo development? [PDF]

open access: yes, 2016
Our aim was to examine size-specific effects of Hyaluronan (HA) on preimplantation embryo development. We investigated the effects of Hyalovet (HA, 500–750 kDa; the size produced by HA synthase-3, which is abundant in the oviduct), or HA treated with ...

Correlated response in early embryonic development in rabbits selected for litter size variability

open access: yesWorld Rabbit Science, 2017
A divergent selection experiment for litter size variability was carried out in rabbits. The litter size variability was estimated as the phenotypic variance of litter size within female.

microRNAs as A Biomarker to Predict Embryo Quality Assessment in In Vitro Fertilization [PDF]

open access: yesInternational Journal of Fertility and Sterility, 2023
Embryo selection for in vitro fertilization (IVF) is an effort to increase the success rate of embryo implantation. Factors influencing the success of embryo implantation include embryo quality, endometrial receptivity, embryo characteristics, and ...

Incidence, Clinical Risk Factors, and Pregnancy Outcomes of Trophectoderm- and Inner Cell Mass-Poor-Quality Blastocysts in Single Blastocyst Transfer Cycles: A Retrospective Cohort Study. [PDF]

open access: yesReprod Med Biol
ABSTRACT Purpose To study incidence, clinical risk factors, and pregnancy outcomes of trophectoderm‐ and inner cell mass–poor‐quality blastocysts in single blastocyst transfer cycles. Design A retrospective cohort study included patients who underwent their first single blastocyst transfer cycle.

Development, Live Birth and Fertility in Mouse Oocytes Penetrated by Spermatids Exposed to the HDAC Inhibitor Scriptaid. [PDF]

open access: yesReprod Med Biol
ABSTRACT Purpose In mouse embryos derived from round spermatid injection (ROSI), low developmental potential due to abnormal histone modification is improved by histone deacetylase (HDAC) inhibitors. However, some studies suggest that the use of such inhibitors leads to the birth of hypomorphic offspring.

#225 : miR-135b Expression Correlated with Aneuploidy in Trophectoderm from IVF Patients: An Approach to NIR-Invasive Screening for Embryo Quality Assessment

open access: yesFertility & Reproduction, 2023
Background and Aims: MicroRNAs (miRNAs) are abundantly expressed in rapidly growing and undifferentiated cells, for example, embryonic stem cells. This led to the discovery that miRNAs are significantly expressed in human embryos and that intracellular ...

The Effect of Prolonged Culture of Chromosomally Abnormal Human Embryos on The Rate of Diploid Cells [PDF]

open access: yesInternational Journal of Fertility and Sterility, 2016
Background A decrease in aneuploidy rate following a prolonged co-culture of human blastocysts has been reported. As co-culture is not routinely used in assisted reproductive technology, the present study aimed to evaluate the effect of the prolonged ...
