The Mysteries Of Human Reproduction

Scientific evidence that a higher partheno-genetic method of human fertilization exists by which a super race may be created. a method distinct from and superior to the animal method, by which 19 virgin mothers in England produced children as confirmed b.

Despite the widespread belief that natural is better when it comes to sex, pregnancy, and parenting, most of us have no idea what "natural" really means; the origins of our reproductive lives remain a mystery. Why are a quarter of a billion sperm cells needed to fertilize one egg? Are women really fertile for only a few days each month? How long should babies be breast-fed? In How We Do It, primatologist Robert Martin draws on forty years of research to locate the roots of everything from our sex cells to the way we care for newborns. He examines the procreative history of humans as well as that of our primate kin to reveal what's really natural when it comes to making and raising babies, and distinguish which behaviors we ought to continue -- and which we should not. Although it's not realistic to raise our children like our ancestors did, Martin's investigation reveals surprising consequences of -- and suggests ways to improve upon -- the way we do things now. For instance, he explains why choosing a midwife rather than an obstetrician may have a greater impact than we think on our birthing experience, examines the advantages of breast-feeding for both mothers and babies, and suggests why babies may be ready for toilet training far earlier than is commonly practiced. How We Do It offers much-needed context for our reproductive and child-rearing practices, and shows that once we understand our evolutionary past, we can consider what worked, what didn't't, and what it all means for the future of our species.

This is a large-format colour-illustrated guide to human reproduction, best described by the authors themselves: "This book offers accessible information about the anatomy of men and women, the physiological steps that lead to conception and gestation and birth, and the means we have to control these events. We hope that high school and college students, young adults, men and women facing decisions about fertility, and the clinicians who care for them will use this book's illustrations and text to pierce the mystery and misinformation that sometimes surrounds these issues. By taking readers step-by-step through the development of egg and sperm, fertilization, implantation, embryonic and fetal growth, and birth as well as methods of birth control, termination of pregnancy, treatment for infertile couples, and menopause, this book hopes to contribute to both the knowledge and the awe that surround human reproduction."
