The intense and extensive debate over human embryonic stem cell research has focused primarily on the moral status of the human embryo. Some commentators assign full moral status of normal adult human beings to the embryo from the moment of its conception. At the other extreme are those who believe that a human embryo has no significant moral status at the time it is used and destroyed in stem cell research. And in between are many intermediate positions that assign an (...) |

The publication of the first study to use gene editing techniques in human embryos (Liang et al., 2015) has drawn outrage from many in the scientific community. The prestigious scientific journals Nature and Science have published commentaries which call for this research to be strongly discouraged or halted all together (Lanphier et al., 2015; Baltimore et al., 2015). We believe this should be questioned. There is a moral imperative to continue this research. |

In this paper I explore some of the moral issues that could emerge from the creation of human–nonhuman chimeras capable of human gamete production and human pregnancy. First I explore whether there is a cogent argument against the creation of HNH-chimeras that could produce human gametes. I conclude that so far there is none, and that in fact there is at least one good moral reason for producing such types of creatures. Afterwards I explore some of the moral problems that (...) |

Nurses and midwives are part of health care in all the stages of our lives from preconception to death. Recent scientific advances have introduced new techniques of screening and diagnosis linked to stem cell isolation and therapies. These could affect us at any age and therefore nurses will be involved as carers and patients advocates for these techniques. In this article stem cell techniques and therapies are outlined, as well as some of the ethical challenges faced by various nursing groups, (...) |

We argue in this essay that (1) the embryo is an irredeemably ambiguous entity and its ambiguity casts serious doubt on the arguments claiming its full protection or, at least, its protection against its use as a means fo research, (2) those who claim the embryo should be protected as "one of us" are committed to a position even they do not uphold in their practices, (3) views that defend the protection of the embryo in virtue of its potentiality to (...) |

A lot of interest has been generated by the possibility of deriving gametes from embryonic stem cells and bone marrow stem cells. These stem cell derived gametes may become useful for research and for the treatment of infertility. In this article we consider prospectively the ethical issues that will arise if stem cell derived gametes are used in the clinic, making a distinction between concerns that only apply to embryonic stem cell derived gametes and concerns that are also relevant for (...) |

Many countries or jurisdictions have legally banned human cloning or are in the process of doing so. In some countries, including France and Singapore, reproductive cloning of humans is a criminal offence. In 2005, the United Nations adopted a ‘Declaration on Human Cloning’, which calls for a universal ban on human cloning. The debate on human reproductive cloning seems to have drawn to a close. However, since reproductive cloning of mammals has become routine in several countries, there is reason to (...) |

Somatic cell nuclear transfer (SCNT) remains a controversial technique, one that has elicited a variety of regulatory responses throughout the world. On March 29, 2005, Canada's Assisted Human Reproduction Act came into force. This law prohibits a number of research activities, including SCNT. Given the pluralistic nature of Canadian society, the creation of this law stands as an interesting case study of the policy-making process and how and why a liberal democracy ends up making the relatively rare decision to use (...) |

One of the goals of medicine is to improve well-being, in line with the principle of beneficence. Likewise, scientists claim that the goal of human embryonic stem cell research is to find treatments for diseases. In hESC research, stem cells are harvested from a 5-day-old embryo. Surplus embryos from infertility treatments or embryos created for the sole purpose of harvesting stem cells are used in the research, and in the process the embryos get destroyed. The use of human embryos for (...) |

This paper discusses two proposals to the US President’s Council on Bioethics that try to overcome the issue of killing embryos in embryonic stem cell research and argues that neither of them can hold good as a compromise solution. The author argues that the groups of people for which the compromises are intended neither need nor want the two compromises, the US government and other governments of countries with restrictive regulation on ES cell research have not provided a clear and (...) |

We discuss in this essay the alternative techniques proposed for the isolation of human embryonic stem cells (hESCs) that attempt to satisfy moral issues surrounding killing embryos but show that these techniques are either redundant or do not achieve their intended aim. We discuss the difficulties associated with defining a human embryo and how the lack of clarity on this issue antagonises the ethical debate and impedes hESC research. We present scientific evidence showing that isolation of hESCs does not necessarily (...) |

Some commentators argue that conception signals the onset of human personhood and that moral responsibilities toward zygotic or embryonic persons begin at this point, not the least of which is to protect them from exposure to death. Critics of the conception threshold of personhood ask how it can be morally consistent to object to the embryo loss that occurs in fertility medicine and research but not object to the significant embryo loss that occurs through conception in vivo. Using that apparent (...) |

The majority of embryos created in natural reproduction die spontaneously within a few weeks of conception. Some have argued that, therefore, if one believes the embryo is a person (in the normative sense) one should find ‘natural’ reproduction morally problematic. An extension of this argument holds that, if one accepts embryo deaths in natural reproduction, consistency requires that one also accepts embryo deaths that occur in (i) assisted reproduction via in vitro fertilisation (IVF) and (ii) embryo research. In a recent (...) |
