Exploring what shapes human development in early pregnancy
This detailed study examines how changes to the chorion and implantation can affect a developing embryo, including the rare cases that produce monstrous outcomes. It presents observed evidence and argues for environmental factors over germinal origins in many cases.
This edition compiles pathological and normal embryos to illuminate the early stages of pregnancy, showing how irregular nutrition and tissue changes can steer development. It combines case observations with plates and drawings to help readers understand how early events influence later outcomes.
- How early implantation and chorion changes can affect embryo growth
- Differences between normal and pathological embryos across several weeks of development
- Evidence from tubal pregnancies and abortion cases to illustrate developmental processes
- Illustrations and plates that compare normal structures with affected ones
Ideal for readers of medical history, embryology, and teratology, who want concrete cases and careful analysis of early developmental biology.
