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.
