Comparison of clinical outcomes following vitrified warmed day 5/6 blastocyst transfers using solid surface methodology with fresh blastocyst transfers

Journal of Human Reproductive Sciences, 2013
Objectives: The literature regarding clinical outcomes following day 5/6 vitrified warmed blastocysts transfer has been conflicting. We decided to evaluate and compare the clinical outcomes following vitrified warmed day 5/6 blastocyst transfer using a ...

The Open Cryotop System Is Effective for the Simultaneous Vitrification of a Large Number of Porcine Embryos at Different Developmental Stages

Frontiers in Veterinary Science, 2022
The Superfine Open Pulled Straw (SOPS) system is the most commonly used method for vitrification of pig embryos. However, this system only allows the vitrification of four to seven embryos per straw.

Prostaglandins in Swine Blastocysts [PDF]

Biology of Reproduction, 1983
The activity of phospholipase A2 (PLA2) and the content of prostaglandins (PGF and PGE-A) in swine blastocysts were determined on Days 7 through 14 of gestation by using radioenzymatic and radioimmunoassay techniques. Both PLA2 activity and PG content increased in the blastocyst with age.

Modeling human trophoblast, the placental epithelium at the maternal fetal interface. [PDF]

, 2020
Appropriate human trophoblast lineage specification and differentiation is crucial for the establishment of normal placentation and maintenance of pregnancy. However, due to the lack of proper modeling systems, the molecular mechanisms of these processes

Embryo Mosaicism Rate in National Referral Hospital of Indonesia Detected Using Next-Generation Sequencing: A Retrospective Study [PDF]

International Journal of Fertility and Sterility
Background: Chromosomal mosaicism, a phenomenon observed in a minority of embryos, showcases its prevalenceand inherent unpredictability, leading to variations in embryo mosaic rates across different centers.

Survival of bovine blastocysts produced in vitro and vitrified in vitri-tip and vitri-top devices. [PDF]

SPERMOVA, 2019
Vitrification is a new technique that has many potential advantages in mammalian oocytes and embryos. In the present work, the objective was to compare of post thawing survival rate by of blastocysts vitrified in vitro in two devices.

Aneuploidy in the Human Blastocyst

Cytogenetic and Genome Research, 2011
Studies of human cleavage stage embryos, 3 days after fertilization of the oocyte, have revealed remarkably high levels of chromosome abnormality. In addition to meiotic errors derived from the gametes, principally the oocyte, mitotic errors occurring after fertilization are also common, leading to widespread chromosomal mosaicism.

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 ...

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

World 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.
