An Atlas Of Human Blastocysts

If you had a dependable method for determining the healthiest and most viable conceptus from a cohort of growing preembryos, replacing more than a single one in order to achieve good pregnancy rates would be moot. Sometime in the not-so-distant future, this may be a reality. Taking a step towards that future, An Atlas of Human Blastocysts vividly i

With hundreds of original photographs, optical micrographs and scanning electron micrographs, this atlas describes the progress of the embryo throughout its development, highlighting the formation and differentiation of organ structures. From the preembryonic and embryo stages to the development of the skeleton and striated muscle, organogenesis of the heart, and development of external genitalia, it provides authoritative answers to the most frequently asked question about the human embryo. With its plethora of outstanding photographs and images, experienced embryologists as well as clinicians and students can compare historical ideas with photographic reality.

Featuring more than 300 full-color photographs, this atlas is a comprehensive guide to the complex procedures used in assisted reproduction. It shows readers how to utilize the latest technologies and correlates the laboratory and clinical components of assisted reproduction. The book depicts oocytes, embryos, and blastocysts at various stages of division and offers guidelines for assessing oocytes and embryos. The authors give detailed instructions on ovarian stimulation, intracytoplasmic sperm injection, assisted hatching, cryopreservation, extended in vitro culturing, preimplantation genetic diagnosis, and embryo transfer techniques. Close attention is also given to assessment of oocytes and embryos from patients with endometriosis and other pathologies.

Presents invaluable data on both open and closed vitrification techniques, and the consequences of either method for survival rates.

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.

The most profound dilemma in assisted reproduction to date is the inability to recognize potentially viable embryos before their replacement into the reproductive tract. Application of increasingly advanced new technology has allowed the field of embryo evaluation to evolve rapidly and dramatically over the past five years.Human Preimplantation Emb

Among the many recent advances in assisted reproduction therapies (ART), improved technologies for identifying viable oocytes, sperm, and embryos are of primary importance. Paradoxically, the latest advances presented at conferences and symposia are often slow to become part of the daily routine in IVF laboratories. Detailing established and develo
