Gendercide is a neologism that refers to the systematic killing of members of a specific sex, either males or females, coined by Mary Anne Warren in her 1985 book Gendercide: The Implications of Sex Selection http://www.gendercide.org/what_is_gendercide.html. The term is intended to be sex-neutral, but it is mostly used in feminism to refer to female victims (feminicide or femicide) but it has also been used to refer to male victims (viricide), e.g. in Jones (1999).
