This was a compilation I put together in 2012 for our homeschooling group.

At the moment when a human sperm penetrates a human ovum, or egg, generally in the upper portion of the Fallopian Tube, a new entity comes into existence. “Zygote” is the name of the first cell formed at conception, the earliest developmental stage of the human embryo, followed by the “Morula” and “Blastocyst” stages. – Marjorie A. England, “What Is An Embryo?” in Life Before Birth, Marjorie A. England (London:Mosby-Wolfe, 1996
The new human zygote has a genetic composition that is absolutely unique to itself, different from any other human that has ever existed, including that of its mother (thus disproving the claim that what is involved in abortion is merely “a woman and her body”). This DNA includes a complete “design,” guiding not only early development but even hereditary attributes that will appear in childhood and adulthood, from hair and eye color to personality traits. – Keith L. Moore and T.V.N. Persaud, The Developing Human: Clinically Oriented Embryology(Philadelphia: W.B. Saunders Co., 1998): 77, 350.
As a general proposition, every human being comes into existence by the fusion of a human egg with a human sperm, but twinning can result in multiple children from one human egg, and there is the potential for cloning of a human embryo. – Judith G. Hall, “Twinning,” The Lancet, 362 (August 20, 2003): 735-43.
The cardiovascular system is the first major system to function. At about 22 days after conception the child’s heart begins to circulate his own blood, unique to that of his mother’s, and his heartbeat can be detected on ultrasound. – Moore and Persaud, The Developing Human: 350-358.
“Human development 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).”

“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.”

The Case Against Abortion: Medical Testimony
How “The Pill” Works As An Abortifacient:
Mechanism of Actions of Birth Control Pills:
//12.1 Mechanism of Action
COCs lower the risk of becoming pregnant primarily by suppressing ovulation. Other possible mechanisms may include
cervical mucus changes that inhibit sperm penetration and the endometrial changes that reduce the likelihood of
implantation.//
