Origin of the terms embryo, gamete and zygote

Abstract

The scope of this article is to answer two questions: first, when were the terms embryo (E), gamete (G) and zygote (Z) coined, and second, who were the scientists who put them in circulation? In order to clarify and document the origin of these three words, a vast amount of biomedical literature, particularly from the late 19th and early 20th centuries, has been reviewed; an undertaking made possible by the free access to the massive repository of available scientific literature on the Internet. Furthermore, as a result of this analysis, I would like to raise some ethical aspects of scientific publication, in particular the obligation of scientists to personally assess the quality and source of data they take from the literature and use in their publications.
