In this latest edition of a classic originally published almost 40 years ago, photographer Nilsson and obstetrician Hamberger explore the miracle of birth, from attraction between a man and a woman to fertilization, pregnancy, labor and delivery; they also discuss infertility and developments in IVF and other treatments. Over 350 new photographs have been added to the fourth edition, including in utero pictures captured with endoscopy and three-dimensional ultrasound technology. Nilsson zooms in on sperm racing towards the egg, the brand-new zygote, the embryo clinging to the lining of the uterus, a tadpole-like fetus and the remarkably developed ear of a 18-week old fetus, among other moments in the process of human reproduction. With Hamberger's updated text on guidance for new parents, progress in fertility treatments, genetics and pregnancy health, the volume should continue to be a vivid reference for the whole family. -- Publishers Weekly
