Human Life and Health Care Ethics, vol. 2: Conception Is the Beginning of Life

“The first cell of a new and unique human life begins existence at the moment of conception (fertilization) when one living sperm from the father joins with one living ovum from the mother. It is in this manner that human life passes from one generation to another. Given the appropriate environment and genetic composition, the single cell subsequently gives rise to trillions of specialized and integrated cells that compose the structures and functions of each individual human body. Every human being alive today and, as far as is known scientifically, every human being that ever existed, began his or her unique existence in this manner, i.e., as one cell. If this first cell or any subsequent configuration of cells perishes, the individual dies, ceasing to exist in matter as a living being. There are no known exceptions to this rule in the field of human biology.”

Dr. George W Corner On Fertilization

Dr. George W Corner, the endocrinologist and research scientist who first isolated and identified the female hormone progesterone, said in the 1940s:

“The fertilization of an egg by the sperm is one of the greatest wonders of nature, an event in which magnificently small fragments of…life are driven by cosmic forces to their appointed end, the growth of a living human being. As a spectacle, it can be compared only with an eclipse of the sun, or the eruption of a volcano. It is in fact the most common and nearest to us of nature’s cataclysms, and yet is very seldom observed because it occurs in a row most people never see – the region of microscopic things.”

Quoted in Nathanson, Bernard N, M.D The Hand of God: a Journey from Death to Life by the Abortion Doctor Who Changed His Mind (Washington DC: Regnery Publishing Inc, 1996) 129 – 130
