Book excerpt: Providing information from the cutting edge of reproductive technology, this full-color atlas vividly illustrates the typical and atypical morphology of human blastocysts collected and cultured during the course of in vitro fertilization treatments. The narrative and the illustrations detail a variety of new reproductive technologies. All photographs are supported by detailed legends and a glossary of terms is included. This atlas is edited by two world-class embryologists both of whom work at the Center for Reproductive Medicine and Infertility at the Weill Medical College of Cornell University.
