Features: The birth of every life is a small miracle. Gazing at the tender infant in our arms, we can't help but wonder: What journey did they go through to reach this world? Starting from the race of 200 million sperm, the of the embryo gradually takes shape. How does the fetus arrange its own nest within the mother's womb to meet survival needs? And how does it evade the mother's immune system to avoid rejection? The book also provides an in-depth analysis of scientific topics such as cord blood and in vitro fertilization. In the pursuit of scientific understanding, we not only learn how we were born but also discover the biological significance behind reproductive mechanisms. Pregnancy is a unique and intimate relationship that occurs between two people. We have all experienced this bond, and half of us are fortunate enough to experience it again. No matter how hard we try, nothing except pregnancy can connect us to another person as closely as this. This squalling, slippery pink little baby—what journey did it go through to reach this world? How can we create something from nothing, nurturing these miraculous little ones? From the moment of conception to feeding the infant in our arms, reproductive biologist David Barrowclough reveals the actual process of pregnancy—the biological mechanisms of embryonic development, not just general "pregnancy tips." He poses many ancient medical questions: Why can women only provide a limited number of eggs? How does the embryo pause the mother's menstrual cycle? How does the mother "know" she is pregnant? What is the evolutionary significance of morning sickness? How are babies put together? Why can the mother accept this "foreign" baby? Why are identical twins never exactly the same? Is it the mother or the baby that determines when labor begins? In terms of comedy, pregnancy has all the qualities: sibling rivalry, gender wars, and crises of gender identity. The author presents new scientific discoveries to refute ancient assumptions and misconceptions. He explores the influence of the mother on the fetus both physiologically and psychologically, some of which extend into adulthood and even affect gender orientation. This is a popular science book that explains the truth about human pregnancy. From an anthropological perspective, studying the human pregnancy process can help us understand where we come from and why we exhibit certain behaviors.
