This book combines the most recent knowledge on the maternal, i.e. oocyte/egg-specific, molecules and processes. The volume covers the most recent advances in a plethora of subjects such as: maternal transfer of immunity, localized RNAs functions and mechanisms of RNA localization, transcriptional repression of maternal messages, maternal inheritance and maternal role of CRISPR/Cas9-based genome editing, chromatin remodeling and epigenetic modifications, maternal function of nucleosomes, maternal mitochondria and energy supply, role of bacterial symbionts and their maternal transmission, acquisition of oocyte polarity and evolution of maternal effect genes, germ plasm and oosome origin and functions, mechanisms of oocyte activation and soma germ cells communication. Currently, no other book on the market combines such a comprehensive list of subjects in one volume. Moreover, the information provided is a cross-section through oocytes from various invertebrate and vertebrate species, which is another unique feature of this book. The readers, therefore, get a completely new and invaluable perspective on all covered subjects.

In recent years increasing numbers of women from wealthy countries have turned to egg donation, egg freezing, and in vitro fertilization to become pregnant, especially later in life. This trend has created new ways of using, exchanging, and understanding oocytes—the reproductive cells specific to women. In The Oocyte Economy Catherine Waldby draws on 130 interviews---with scientists, clinicians, and women who have either donated or frozen their oocytes or received those of another woman---to trace how the history of human oocytes' perceived value intersects with the biological and social life of women. Demonstrating how oocytes have come to be understood as discrete and scarce biomedical objects open to valuation, management, and exchange, Waldby examines the global market for oocytes and the power dynamics between recipients and the often younger and poorer donors. With this exploration of the oocyte economy and its contemporary biopolitical significance, Waldby rethinks the relationship between fertility, gendered experience, and biomedical innovation.

The last decade has seen remarkable advances in human ge netics. Once the correct chromosome number of the human genome was ascertained, a wide variety of diseases was rec ognized as due to numerical chromosome anomalies. There followed the discovery that spontaneous abortions are the result of chromosome errors, and specific band patterns of chromosomes allowed identification of minute lesions. The techniques of cell hybridization now allow specific gene assign ment to chromosomes and even to distinct loci on their arms. All this was possible because of the ease with which metaphase chromosomes can be obtained and manipulated. The much older technique of analysis of meiotic chromosomes has taken a back seat in this exciting era. Being much less readily accessi ble, spermatogonial analysis is much less frequently under taken and is less successful. Even more difficult for study is the female meiotic process. Not only is meiosis extraordinar ily long, spanning from before birth to ovulation, the tech niques for its study and the patience required for detailed inquiry have been significant obstacles. At the same time, the suspicion that female meiotic analysis should not only be rewarding but that it may be mandatory has been with us ever since it was recognized that a positive correlation exists between chromosomal nondisjunction and maternal age. Before the intricacies of chromosomal behavior that are re sponsible for nondisjunction are understood, however, it is necessary that we comprehend the normalcy of the process.

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 human oocyte or egg is the rarest and most rapidly ageing cell in the body, and yet one that is essential for fertility. This book is about the development, biology and pathology of the oocyte, and new technologies to manipulate, enhance, and control fertility. These technologies are paving the way for overcoming infertility, avoiding inherited diseases, and creating genetically engineered animals from embryo stem cells and cloning. This progress would have been impossible without the myriad of scientific and technical developments covered in this book, including the ability to manipulate and fertilize oocytes in vitro. World-leading experts have contributed to the first book for many years on basic and applied science of the egg, its clinical manipulation, and its pivotal role in reproductive medicine and biology. It will be an essential reference for scientists and clinicians in reproductive medicine and animal breeding technology, and everyone involved in treating infertility.

Studies of oogenesis occupy an important place in current in vestigations in developmental biology. Today no one has any doubt whatsoever that oogenesis is not just the prelude to development, but is development itself, and a very essential part of it. These words of an eminent Soviet scientist, B. L. As taurov , taken by T. B. Aizenshtadt as an epigraph to her chapter in this book, make a good epigraph for the entire book. It is now clear that during oogenesis not only vast reserves of ribosomes and mitochondria, of yolk, carbohydrates, and lipids, and of enzymes for protein and nucleic acid synthesis and for carbohydrate and fat metabolism (which ensures the energy supply and metabolism of the oocyte and the developing embryo) are formed, but also long-lived mRNA and proteins are synthesized, which determine both the completion of oocyte maturation and the initial stages of embryonic development. In the last 15-20 years, the use of molecular biology methods, electron microscopy, autoradiography, and microsurgical methods of experimental embryology in studying the pre-embryonic development of animals has greatly increased our knowledge of oogenesis. This has led to the need to systematize the data obtained, to reinter pret old ideas, and to review the results obtained by new research trends which have emerged in the last few years and which are of general biological interest. Such a task was undertaken in the book Sovremennye Problemy Oogeneza (Current Problems of Oogenesis), published in 1977 (in Russian).

This volume covers the current knowledge base on the role of signaling and environmental pathways that control the normal development of germline stem cells, meiotic progression of oocytes, events of oocyte maturation and fertilization, and the birth of an embryo. Germ cells are uniquely poised to sustain life across generations through the fusion of oocyte and sperm. Because of the central importance of germ cells to life, much work has been dedicated to obtaining a clear understanding of the molecular and signaling events that control their formation and maintenance. Germ cells are set aside from somatic cells in the embryo and go through specialized meiotic cell cycles as the animal matures. These cell cycles are interspersed with long periods of arrest. In human females, meiosis I is initiated in the fetus. At birth, oocytes are arrested in meiosis I; after puberty, every month an oocyte initiates meiosis II – ovulation. Upon sperm availability these cells are fertilized, generate an embryo, and the cycle-of-life continues. During meiotic I progression and arrest, the fitness of oocytes and their progeny are likely influenced by environmental cues and signaling pathways. A lot of recent work has focused on understanding the mechanisms that regulate oocyte fitness and quality in humans and vertebrates. Much of our understanding on the events of meiosis I and germline stem cell populations comes from work in invertebrates, wherein the germline stem cells produce oocytes continuously through adult development. In both inverbrates and vertebrates nutritional and signaling pathways control the regulation of stem cells in such a manner so as to couple production of gametes with the nutritional availability. Additionally, mature oocytes arrest both in meiosis I and meiosis II, and signaling and nutritional pathways have been shown to regulate their formation, and maintenance, such that despite long periods of arrest, the oocyte quality is assured and errors in chromosome segregation and varied cytoplasmic events are minimal.

This book addresses the growing needs in deciphering the biological processes associated with fish reproduction, in view of the growth of aquaculture and the dwindling natural stocks of commercially important fish. It presents a comprehensive overview on egg production in fish, from the standpoint of the oocyte. With this view in mind, the book includes chapters on oocyte development (oogenesis), hormonal regulation and hormone receptors, formation of the egg envelopes, growth, accumulation of nutrients and maternal transcripts, maturation, hydration, ovulation and fertilization. A special emphasis is placed on using state-of-the-art tools including electron microscopy for discerning the ultra-structure of the follicle and genomic/proteomic tools to fully understand biological basis of fish reproduction. Studies on promoting oocyte maturation, ovulation and spawning in farmed fish and preservation of fish oocytes at low temperatures are also included. The book will appeal to University lecturers, students, research scientists and those associated with culture of fish in freshwater or marine aquaculture.
