Artificial insemination or vitro embryo is one of the Medical Scientifics’ achievements be used for helping the modern human being. This matter would governed by particular ethical and law rules that would be distinguished from rules governing on the other product of the human bodies. Although vitro embryo can be changed to the human and obtained personality, but before it becomes to fetu...

 Developments research have made culturing human embryos beyond the 14-day limit seem technologically feasible. In article “Emerging Human Embryo Research Technologies, Rule, and Special Status of Embryo,” authors examine a proposal for new embryo embryoid guidelines by reviewing history emerging areas that are impacted these...
background: it has been demonstrated that performing a mock embryo transfer (et) significantly improves the pregnancy rate in ivf cycles. the mock et could be performed prior to the stimulation cycle or immediately before real et. the problem of the first procedure is the possibility of variation in the uterine position and or cervico�uterine angle. objective: the purpose of this study was to d...
background: natural endometrium in frozen-thawed embryo transfer (fet) may have some benefits upon implantation in patients with repeated implantation failure (rif). it might be due to possible differences between natural and stimulated endometrial growth factors and cytokins secretions. objective: the objective of this study was to compare the pregnancy rate of fet on modified natural cycle ve...
Background: Mice are the most commonly used animal in reproductive research and following the urgent need for these type of studies and also due to the increased interest in the ethical principle of animal rights, four various inbred and outbred strains of the laboratory mouse were evaluated to select the more efficient one for reproductive research. Materials and methods: 60 female and 16 mal...
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...
The objective of this paper is to stimulate academic debate on embryo and fetal research from the perspective of the drafting of a protocol to the European Convention on Biomedicine. The Steering Committee on Bioethics of the Council of Europe was mandated to draw up such a protocol and for this purpose organised an important symposium on reproductive technologies and embryo research, in Strasb...
