40 quotes from medical experts and textbooks that prove human life begins at conception
“Fertilization is the process by which male and female haploid gametes (sperm and egg) unite to produce a genetically distinct individual.”
Signorelli et al., Kinases, phosphatases and proteases during sperm capacitation, CELL TISSUE RES. 349(3):765 (Mar. 20, 2012)
“The government’s own definition attests to the fact that life begins at fertilization. According to the National Institutes of Health, ‘fertilization’ is the process of union of two gametes (i.e., ovum and sperm) ‘whereby the somatic chromosome number is restored and the development of a new individual is initiated.'”
Steven Ertelt”Undisputed Scientific Fact: Human Life Begins at Conception, or Fertilization” LifeNews.com11/18/13
“Human life begins at fertilization, the process during which a male gamete or sperm (spermatozoo developmentn) unites with a female gamete or oocyte (ovum) to form a single cell called a zygote. This highly specialized, totipotent cell marked the beginning of each of us as a unique individual.” “A zygote is the beginning of a new human being (i.e., an embryo).”
Keith L. Moore, The Developing Human: Clinically Oriented Embryology, 7th edition. Philadelphia, PA: Saunders, 2003. pp. 16, 2.
“In that fraction of a second when the chromosomes form pairs, the sex of the new child will be determined, hereditary characteristics received from each parent will be set, and a new life will have begun.”
Clark Edward and Corliss Patten’s Human Embryology, McGraw – Hill Inc., 30
“Your baby starts out as a fertilized egg… For the first six weeks, the baby is called an embryo.”
Prenatal Care, US Department Of Health And Human Services, Maternal and Child Health Division, 1990
“The zygote and early embryo are living human organisms.”
Keith L. Moore & T.V.N. Persaud Before We Are Born – Essentials of Embryology and Birth Defects (W.B. Saunders Company, 1998. Fifth edition.) Page 500
“Thus a new cell is formed from the union of a male and a female gamete. [sperm and egg cells] The cell, referred to as the zygote, contains a new combination of genetic material, resulting in an individual different from either parent and from anyone else in the world.”
Sally B Olds, et al., Obstetric Nursing (Menlo Park, California: Addison – Wesley publishing, 1980) P 136
“Development begins with fertilization, the process by which the male gamete, the sperm, and the femal gamete, the oocyte, unite to give rise to a zygote.”
T.W. Sadler, Langman’s Medical Embryology, 10th edition. Philadelphia, PA: Lippincott Williams & Wilkins, 2006. p. 11.
“[The zygote], formed by the union of an oocyte and a sperm, is the beginning of a new human being.”
Keith L. Moore, Before We Are Born: Essentials of Embryology, 7th edition. Philadelphia, PA: Saunders, 2008. p. 2.
“[All] organisms, however large and complex they might be as full grown, begin life as a single cell. This is true for the human being, for instance, who begins life as a fertilized ovum.”
Dr. Morris Krieger “The Human Reproductive System” p 88 (1969) Sterling Pub. Co
“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."
James Bopp, ed., Human Life and Health Care Ethics, vol. 2 (Frederick, MD: University Publications of America, 1985)
Science confirms that human life begins at fertilization
"The scientific community continues to prove that human life begins at conception (fertilization)."
“Human development begins at fertilization when a sperm fuses with an oocyte to form a single cell, the zygote.”
“All major external and internal structures are established during the fourth to eighth weeks.”
“Embryos in the sixth week show spontaneous movements, such as twitching of the trunk and developing limbs.”
