A novel isolator-based system promotes viability of human embryos during laboratory processing [PDF]

, 2012
In vitro fertilisation (IVF) and related technologies are arguably the most challenging of all cell culture applications. The starting material is a single cell from which one aims to produce an embryo capable of establishing a pregnancy eventually ...

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 ...

Endometrial stromal cells of women with recurrent miscarriage fail to discriminate between high- and low-quality human embryos [PDF]

, 2012
Background The aetiology of recurrent miscarriage (RM) remains largely unexplained. Women with RM have a shorter time to pregnancy interval than normally fertile women, which may be due to more frequent implantation of non-viable embryos.

#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 ...

Effect of blastocyst morphology on the incidence of monozygotic twinning pregnancy after single blastocyst transfer

, 2023
Aims: To explore whether blastocyst morphology [blastocyst stage, inner cell mass (ICM), and trophectoderm (TE) grading] impacts the occurrence of monozygotic twinning (MZT) after single blastocyst transfer (SBT).Materials and methods: A single-center ...
