BACKGROUND Single embryo transfer (SET) after IVF/ICSI has been shown to result in an acceptable pregnancy rate in selected subjects. In our unit, SET is routinely carried out among women under the age of 36 in the first or second treatment cycle when a top-quality embryo is available. In order to define further the selection criteria for SET, we have analysed the outcome of elective SET (eSET)...

Since it appeared that plaque formation in monolayers of primary chick embryo cells might provide a simple technique for the typing of Herpesvirus hominis strains, 100 isolates were tested for their efficiency of plating (EOP) on chick embryo cells versus plating on human embryonic fibroblasts. EOP values varied from 10(0) to 10(-6): 88% of the strains of genital origin had an EOP equal to or g...

Background: During ICSI, motile sperm with normal morphology are selected and injected into oocyte. But integrity of chromatin is not observable. Therefore, researchers are trying for to present novel method of sperm selection with high percentage of normal chromatin. HOST test is a useful assay of functional integrity of the human sperm membrane. We decide to use HOST test after DGC for infert...

The promise of medical innovation has long evoked social commentary, particularly when personal reproductiveautonomy may be impacted. Development of the oral contraceptive, effective and safe surgical sterilization, and later IVF and ICSI are among the revolutionary developments where initial reaction was dubious, but eventually, each was accorded mainstream status as clinical experience accumu...

background: successful embryo transfer (et) technique is a fateful step of all efforts to achieve live births from in vitro produced embryos in assisted reproductive techniques or in knockout, transgenic or cloned animal projects. small reproductive tract of mice and limitation of current techniques may not well satisfy the requirements for mass production of genetically modified mice. genetic ...

Embryo transfer in swine (ETS) has been used for commercial and breeding application only to a limited extent. However this technique is an essential prerequisite for the application of new reproductive techniques in pigs. This paper will give an overview on steps of pig embryo transfer including selection and stimulation of donor sows, recovery of embryos, embryo handling and the transfer of r...

BACKGROUND An increased incidence of aneuploid embryos has been recently described from azoospermic men. The aim of this study was to assess if embryo selection on day 5, based on morphological criteria, would be different from the selection based on PGD for aneuploidy screening (AS) in couples undergoing ICSI for male azoospermia. METHODS Sixty-two cycles of testicular sperm extraction (TESE...

A critical factor that influences the success of an in-vitro fertilization (IVF) treatment cycle is quality transferred embryo. Embryo morphology assessments, conventionally performed through manual microscopic analysis suffer from disparities in practice, selection criteria, and subjectivity due to experience embryologist. Convolutional neural networks (CNNs) are powerful, promising algorithms...

BACKGROUND In human reproduction, embryo implantation is complex and poorly understood. At present, no single markers are used in routine treatment to assay biochemical functions of the human embryo. Soluble human leukocyte antigen-G (sHLA-G) could be considered a possible marker of embryo developmental potential. It is localized primarily on the extravillous trophoblast, making this antigen a ...
