First published in 1965, A Child Is Born offered an unprecedented glimpse of life inside the womb. This fourth edition brings improved photographic technology and a revised text to this awe-inspiring journey from fertilization to birth. Lennart Nilsson uses a new high-definition ultrasound technique, scanning electron and light microscopes, and advanced fibre optics to make an unparalleled record of the unseen world within our bodies. Here, in a series of close-up images, the miracle of human reproduction unfolds: the egg travelling down the fallopian tube; the sperm racing to meet it; the moment of fertilization; the very first cell division; the tiny embryo attaching to the uterine wall; the growth of eyes, ears, fingers and toes; and finally the moment of delivery itself - give an astonishing glimpse of the first moments of life. The updated text also features authoritative advice for new parents, plus information on recent advances in fertility treatments, state-of-the-art testing, genetics, environmental factors and pregnancy health.
