The method of vitrification of oocytes and embryos is fundamental for the outcome of IVF. This atlas presents data on both closed system and open vitrification techniques, and the consequences of each method for survival rates, aiding the comparison of vitrification methods. Structured on a patient-by-patient basis, the atlas describes 100 clinically documented case studies that follow the evolution of cryopreserved blastocysts between warming and blastocyst transfer. It relates fresh to post-warming blastocyst morphology and to response to controlled ovarian hyperstimulation. For each case, pronuclear morphology and synchrony, as well as embryo morphology, are reported and described. Data on indications for treatment, stimulation type and duration, are accompanied by over 400 high-quality images of vitrified blastocysts. Covering the state-of-the-art techniques, this atlas is an essential aid in selecting the vitrification method for clinical embryologists and physicians in reproductive medicine.

The assessment and selection of oocytes and embryos is fundamental to the live birth rate data of all IVF units, the parameter that is used to gauge a clinic's success and credibility. This new atlas contains over 1000 high-quality images of oocytes, zygotes and embryos, presented with accompanying data on indications for treatment, stimulation type and duration, as well as short medical histories of each couple and final outcome of treatment. All images in the book can be downloaded from the accompanying CD-ROM. Structured on a patient-by-patient basis, the atlas describes 100 clinically documented case studies that follow the evolution of oocytes and zygotes between day two and day five. Pronuclear morphology and synchrony as well as embryo morphology are reported and described for each case. Written and produced by experienced embryologists, this practical atlas is an important resource for clinical embryologists and physicians in reproductive medicine.
