the success rate of embryo production critically depends on several factors. one of the pivotal factors is a technique used for the whole procedure of in vitro fertilization (ivf) and in vitro embryo culture (ivc) (1, 2). besides the technique selected for ivf / in vitro embryo production (ivep), there is an important consideration called ivf/ivep culture dishes disinfection (3). for many years...
BACKGROUND The majority of research aimed at improving embryo development in vitro has focused on manipulation of the chemical environment, examining details such as energy substrate composition and impact of various growth factors or other supplements. In comparison, relatively little work has been done examining the physical requirements of preimplantation embryos and the role culture platfor...
Most of the systematic studies used in the development of human embryo culture media have been done first on mouse embryos. The general use of NMRI outbred mice is a model for toxicology, teratology and pharmacology. NMRI mouse embryo exhibit the two-cell block in vitro. The objective of this study was to evaluate and compare the effects of four kinds of culture media on the development of zygo...
Purpose: The aim of this study was to evaluate the effect of different modifications of sequential synthetic oviductal_fluid (SOF) culture system on developmental competence of in vitro matured/fertilized cattle embryos. Materials and Methods: Bovine oocytes were matured and fertilized in vitro and then presumptive zygotes were randomly cultured for up to 9 days in different modifications of SO...
Background: In embryological culture dishes, there is a temperature decline when they are removed outside incubators. This study aimed at investigating the effects of this temperature decline within a certain time frame, the type of culture dish with or without the use of laminar air flow and whether it is possible to achieve a sufficient thermal control with the use of a heating stage. Materia...
abstract in this experiment the effects of two type of medium cultures, gibberellic acid and dark/cold and light/warm culture conditions on mature embryos germination of a local cultivar of walnut were investigated. the mature fruits were collected at 22 weeks postanthesis and after disinfection the mature embryo along with cotyledon pieces were excised and then were cultured on mt and modified...
Background: This study was carried out to evaluate the pattern of reactive oxygen species (ROS) variations during in vitro oocyte maturation and embryo development in sheep, and to investigate whether embryo culture condition and the presence of cell-permeable superoxide dismutase mimetic [Manganese (III) meso-tetrakis (4-benzoic acid) porphyrin (MnTBAP)] can influence ROS pattern. Materials an...
Both cleavage-stage and blastocyst-stage embryo transfer policieshave advantages and drawbacks.Potential advantages of blastocyst culture and transfer in human IVF include: i. synchronization of the embryo with the female tract leading to increasedimplantation rates; thereby, reducing the need for multipleembryo transfers, ii. assessment of viability of an embryobefore transfer. This can be ach...
