From Egg to Embryo


Book Description

This book is about the development of the animal embryo starting from the fertilised egg. The emphasis is on the problem of pattern formation: how cells in different regions of the embryo become programmed to form the various structures of the body in the correct relative positions.




How to Prepare the Egg and Embryo to Maximize IVF Success


Book Description

This comprehensive review of the factors that affect the harvesting and preparation of oocytes and the management of embryos will allow practitioners to make evidence-based decisions for successful IVF. The book reviews and re-considers the value of strategies and outcomes in the management of fertility and conception rates, centred on the production of oocytes, and successful development of the embryo. Authored by leading experts in the field, chapters engage with treatments and strategies that affect the production of oocytes and embryos, optimizing outcomes in the management of female fertility, conception rates, and live births. This vital guide covers controlled ovarian hyperstimulation, the role of AMH in determining ovarian reserve, and primary stimulation agents and the use of adjuncts. Integral for all clinicians and embryologists working in reproductive medicine units, readers are provided with evidence-based, comprehensive advice and review of all factors affecting the management of oocytes and the embryo that are vital for successful IVF cycles.




Freezing Fertility


Book Description

Welcomed as liberation and dismissed as exploitation, egg freezing (oocyte cryopreservation) has rapidly become one of the most widely-discussed and influential new reproductive technologies of this century. In Freezing Fertility, Lucy van de Wiel takes us inside the world of fertility preservation—with its egg freezing parties, contested age limits, proactive anticipations and equity investments—and shows how the popularization of egg freezing has profound consequences for the way in which female fertility and reproductive aging are understood, commercialized and politicized. Beyond an individual reproductive choice for people who may want to have children later in life, Freezing Fertility explores how the rise of egg freezing also reveals broader cultural, political and economic negotiations about reproductive politics, gender inequities, age normativities and the financialization of healthcare. Van de Wiel investigates these issues by analyzing a wide range of sources—varying from sparkly online platforms to heart-breaking court cases and intimate autobiographical accounts—that are emblematic of each stage of the egg freezing procedure. By following the egg’s journey, Freezing Fertility examines how contemporary egg freezing practices both reflect broader social, regulatory and economic power asymmetries and repoliticize fertility and aging in ways that affect the public at large. In doing so, the book explores how the possibility of egg freezing shifts our relation to the beginning and end of life.




Maternal Control of Development in Vertebrates


Book Description

Eggs of all animals contain mRNAs and proteins that are supplied to or deposited in the egg as it develops during oogenesis. These maternal gene products regulate all aspects of oocyte development, and an embryo fully relies on these maternal gene products for all aspects of its early development, including fertilization, transitions between meiotic and mitotic cell cycles, and activation of its own genome. Given the diverse processes required to produce a developmentally competent egg and embryo, it is not surprising that maternal gene products are not only essential for normal embryonic development but also for fertility. This review provides an overview of fundamental aspects of oocyte and early embryonic development and the interference and genetic approaches that have provided access to maternally regulated aspects of vertebrate development. Some of the pathways and molecules highlighted in this review, in particular, Bmps, Wnts, small GTPases, cytoskeletal components, and cell cycle regulators, are well known and are essential regulators of multiple aspects of animal development, including oogenesis, early embryogenesis, organogenesis, and reproductive fitness of the adult animal. Specific examples of developmental processes under maternal control and the essential proteins will be explored in each chapter, and where known conserved aspects or divergent roles for these maternal regulators of early vertebrate development will be discussed throughout this review.

Assisted Reproductive Technology Surveillance


Book Description

Offers a comprehensive guide to assisted reproductive technology surveillance, describing its history, global variations, and best practices.




Atlas of Chick Development


Book Description

This outstanding work is the only modern book devoted to the chick embryo and has been an essential resource for geneticists, molecular and developmental biologists, and other life scientists who use the chick embryo as their research model. This new enlarged and updated second edition is published in response to continuing demand. The text provides a detailed description of development, from fertilization to hatching, with emphasis on the earlier stages though also covering individual organ systems in detail. There are reviews of the more recent molecular research and a new section highlighting the important landmarks in the history of chick embryology which have had an impact on our understanding of developmental processes. The book is beautifully illustrated with 74 text-figures and over 500 photographs, including nearly 200 new scanning electron micrographs. - Updated and expanded text to accompany diagrams - More than 200 new labelled scanning electron micrographs showing individual tissues in great detail - Reviews of recent molecular research - Discusses the roles of genes such as Hox genes, BMPs, and sonic hedgehog during early development - New sections on genetical anomalies, techniques, and the poultry industry




Comprehensive Gynecology


Book Description

In the 25 years since the first edition of Comprehensive Gynecology, many scientific advances have occurred in medical practice. The first four editions were largely the work of the original four editors: Drs. William Droegemueller, Arthur L. Herbst, Daniel R. Mishell, Jr., and Morton A. Stenchever...With the staggering volume of medical literature published and the complexities of the gynecologic subspecialties, we have collaborated with additional experts for the sixth edition. We've "examined disease" and added a new chapter on the interaction of medical diseases and female physiology. We've "investigated discord" with new authors to completely rewrite the emotional and psychological issues in gynecology and the legal issues for obstetrician-gynecologists. Other chapters have delved into the controversies in breast cancer screening, vitamin D use, the ongoing debates in hormone therapy, and vaginal mesh use for pelvic organ prolapse surgery.
