Fertilization signatures as biomarkers of embryo quality

Human Reproduction, 2022
Abstract Fertilization underpins the vital transition from gametic meiosis to embryonic mitosis. For decades, in human IVF, microscopic observation at a single time point has limited our appreciation of the morphokinetic complexity of this process. More recently, the introduction of time lapse technology—also enhanced by combination with

Morphometric analysis of gametes and embryos is crucial for optimizing Intracytoplasmic Sperm Injection outcomes [PDF]

Cellular, Molecular and Biomedical Reports
Morphometric analysis of gametes and embryos is crucial for optimizing Intracytoplasmic Sperm Injection (ICSI) outcomes. This study aimed to evaluate the importance of morphometric parameters at oocyte, zygote, and embryo stages, focusing on their ...

Association between Number of Formed Embryos, Embryo Morphology and Clinical Pregnancy Rate after Intracytoplasmic Sperm Injection [PDF]

Revista Brasileira de Ginecologia e Obstetrícia, 2016
Introduction Infertility has a high prevalence in the general population, affecting 5 to 15% of couples in reproductive age. The assisted reproduction techniques ( ART ) include in vitro manipulation of gametes and embryos and are an important treatment

Comparative study of obstetric and neonatal outcomes of live births between poor‐ and good‐quality embryo transfers

Reproductive Medicine and Biology, 2018
Purpose To evaluate the effect of embryo quality on pregnancy outcomes. Methods This retrospective analysis included 80 live singleton births, resulting from morphologically good‐quality embryo transfers, and 25 live singleton births that resulted from ...

#153 : Sperm Motility: Effect on Fertilization Rate and Embryo Quality in Patients Undergo Intracytoplasmic Sperm Injection in Indonesia

Fertility & Reproduction, 2023
Background and Aims: Progressive motility may be an indicator of adequate metabolic activity of the sperm; it is important in ICSI as it helps embryologists in picking a viable and best spermatozoa for injection.

Time-lapse technology for embryo culture and selection

Upsala Journal of Medical Sciences, 2020
Culturing of human embryos in optimal conditions is crucial for a successful in vitro fertilisation (IVF) programme. In addition, the capacity to assess and rank embryos correctly for quality will allow for transfer of the potentially ‘best’ embryo first,

Elevated basal FSH and embryo quality: lessons from extended culture embryos [PDF]

Journal of Assisted Reproduction and Genetics, 2009
The relationship between elevated basal FSH and embryo quality remains a topic of heated discussion among practitioners of ART. Some authors suggest a negative effect of raised FSH on the quality of embryos and therefore on IVF treatment outcome. We postulate that women with elevated FSH who respond well to ovarian stimulation and have embryos to ...

Morphological assessment of preimplantation embryo quality in cattle.

Reproduction (Cambridge, England) Supplement, 2019
The extensive use of embryo technologies has emphasized the need for assessing embryo quality by morphological techniques, such as transmission electron microscopy, immunocytochemistry for confocal laser scanning microscopy and fluorescence in situ ...

Relationship between embryo quality and aneuploidies

Reproductive BioMedicine Online, 2006
Many high-grade embryos selected for transfer according to their morphological evaluation were detected to have chromosomal abnormalities after aneuploidy screening for infertility by preimplantation genetic diagnosis (PGD). The aim of this study was to detect if there is any correlation between embryo quality and genetic status. The chromosomal status

Effect of Melatonin Supplementation on In Vitro Developmental Competence of Bovine Oocyte: A Systematic Review and Meta-Analysis

Veterinary Medicine International
Melatonin application in in vitro embryo production (IVEP) constitutes a promising research focus. Nevertheless, there remains a lack of comprehensive meta-analytical evidence assessing its effects in the bovine species. The present systematic review and
