95% of those self-selected respondents said that life began at fertilization, when a sperm and egg merge to form a single-celled zygote. (dailymaverick.co.za)

Indeed, the penetrated oocyte and the ootid, along with the zygote, constitute Stage One of human embryonic development. (lifeissues.net)
Scientifically something very radical occurs between the processes of gametogenesis and fertilization-the change from a simple part of one human being (i.e., a sperm) and a simple part of another human being (i.e., an oocyte-usually referred to as an 'ovum' or 'egg'), which simply possess 'human life,' to a new, genetically unique, newly existing, individual, whole living human being (an embryonic single-cell human zygote).
