Gene editing of the human embryo: tensions and controversies among scientists

Abstract

Objective This study analyzed the relation between the position of scientists on embryo editing and the different types of knowledge involved. Method A lexical analysis of 151 scientific articles in the PubMed and Web of Science databases was conducted using the IRAMUTEQ software. Results The results showed that gene editing in embryos is presented in two argumentative branches: the first refers to the editing technique and its possibilities; the second discusses the impacts of these techniques on the public arena. The results demonstrate a consensus regarding the potential of editing; however, dilemmas about its effectiveness were also highlighted. Conclusion The presence of ethical conflicts with embryo editing among the specialists was evidenced especially regarding the birth of genetically modified babies. Therefore, gene editing is marked by conflicts that are not limited only to biological contexts, but that encompasses different aspects of social life.
