Human germline genome editing is increasingly being seen as acceptable provided certain conditions are satisfied. Accordingly, genetic modifications would take place on eggs or sperm (or their prec...

Following the debate in the UK House of Lords, in December 2012, uncertainty remains as to the manner in which human and non-human interspecies embryos are differentiated in law.

The advantages and risks of a number of new genome modifying procedures seeking to create healthy or enhanced individuals, such as Maternal Spindle Transfer, Pronuclear Transfer, Cytoplasmic Transfer and Genome Editing, are currently being assessed from an ethical perspective, by national and international policy organizations. One important aspect being examined concerns the effects of these procedures on different kinds of identity. In other words, whether or not a procedure only modifies the qualities or properties of an existing human being, meaning (...) that merely the qualitative identity of this single individual is affected, or whether a procedure results in the creation of a new individual, meaning that a numerically distinct human being would have come into existence. In this article, the different identity arguments proposed, so far, are presented with respect to these novel reproductive procedures. An alternative view is then developed using the Origin Essentialism argument to indicate that any cha... (shrink)

With the development of new procedures in the production of synthetic human gametes it has become important to re-examine the manner in which reproductive cells, taking part in the generation of children, can be understood. Though this can be attempted from many different perspectives, the present study will examine the possibility of considering gametes as representing the persons from whom they originated. From this perspective, it is possible to suggest that, in procreation, the entirety of each human sperm cell may (...) represent and reveal the man from whom it was produced and the entirety of each human egg cell may represent and reveal the woman from whom it was produced. The possible ethical consequences of using synthetic gametes for those who hold this perspective together with their understanding of relational identity will also be examined. (shrink)
