The importance of cytoplasmic strings during early human embryonic development
Frontiers in Cell and Developmental Biology, 2023 Objectives: During human in vitro fertilisation (IVF) treatments, embryologists attempt to select the most viable embryos for embryo transfer (ET). Previously, embryos were evaluated based on light microscopic morphological parameters.

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.

Anti-Mullerian hormone: a marker for oocyte quantity, oocyte quality and embryo quality?
, 2008 Serum anti-Mullerian hormone (AMH) concentrations decline with increasing age and constitute a Sensitive marker for ovarian ageing. In addition, basal serum AMH concentrations predict ovarian response during IVF cycles. Concomitantly, oocyte quantity and

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

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,
