Comparative Embryo Development Outcomes following Extending Embryo Culture to Day 6: A Retrospective Cohort Study [PDF]

International Journal of Fertility and Sterility, 2023
Background: Past studies have shown that culturing slow-growing embryos from day 5 to day 6 may increase vitrification yield. This study aims to evaluate if the proportion of embryos eligible for vitrification increases by growing embryos not vitrified ...

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.

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.

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

Fertility & 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 ...

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

International 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 ...

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

International 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 ...

Correlation of the position and status of the polar body from the fertilized oocyte to the euploid status of blastocysts

Frontiers in Genetics, 2022
Polar bodies are tiny cells that are extruded during oocyte meiosis and are generally considered not essential for embryonic development. Therefore, polar bodies have been widely used as important materials for the preimplantation genetic diagnosis of ...

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.

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.
