Zebrafish is a model organism that has become increasingly popular in recent years due to some of the advantages it when compared traditional organisms. Its genetic similarity with humans contributed significantly elucidation molecular mechanisms underlying diseases. Moreover, external fertilization and rapid embryonic development zebrafish embryos have made attractive many research areas. The ...

Various assisted reproductive techniques have been developed and refined to obtain a large number of offspring from genetically superior animals or obtain offspring from infertile (or subfertile) animals. The embryo transfer is one assisted reproductive technique developed well, aimed at increased productivity of selected females, disease control, importation and exportation of livestock, rapid...

Research suggests that cloning is incapable of producing a viable embryo when it is used on primate eggs. In fact, the entity created may not qualify as an embryo at all. If the results stand, cloning avoids the moral objections typically lodged against it, and cloning is itself an "alternative source" of stem cells.

Most couples enrolled in Assisted Reproductive Technologies' (ART) treatments need to make decisions regarding embryo disposition, as they are asked to sign a consent form about embryo donation for research. Beyond the current assessment of patients' individual experiences and levels of satisfaction with care delivery, we argue that it is crucial to provide stakeholders in health systems with f...

promise of research involving human embryos and fetuses for the advancement of basic science as well as for the development of lifesaving vaccines and therapies. Such research continues to this day as scientists seek new treatments for a variety of diseases, such as Alzheimer’s disease, Parkinson’s disease, diabetes, heart disease and kidney failure. But government funding for human embryo and ...

Harris begins his provocative paper in this way: I make two appeals to consistency, or to “parity of reasoning,” that I believe show that no one who either has used or intends to use sexual reproduction as their means of procreation, nor indeed anyone who has unprotected heterosexual intercourse, nor anyone who finds in vitro fertilization (IVF) acceptable, nor anyone who believes that abortion...
