The Science of Pregnancy 
The Complete Illustrated Guide from Conception to Birth

‘Beautifully illustrated, detailed and clear, this is a wonderful introduction to human reproduction’ — Professor Alice Roberts
Follow the amazing transformation that occurs as a baby develops from a single cell into a fully formed human body. Hundreds of spectacular images show you the progress of human pregnancy in unprecedented detail. The computer generated imagery, illustrations, scans, and photographs show exactly how a baby changes and grows during pregnancy, and how the female body adapts to carry it. A chapter on labour and birth explains these processes with step-by-step illustrations and easy-to-grasp text.
The Science of Pregnancy also looks at the nature of human pregnancy, including how it evolved, and explores the anatomy and physiology of both the male and female reproductive systems. The mysteries of DNA and genetics are unravelled and explained in clear, illustrated detail, including patterns of inheritance and the interplay of genes and environment. The book also provides straightforward, illustrated information on possible problems before, during, and after birth.
Fascinating, clear, and authoritative, this new and updated edition of The Science of Pregnancy is the ideal visual guide for prospective parents and medical and midwifery students
