Oocyte Biology In Fertility Preservation

Oocyte cryopreservation entails important potential advantages for humanIVF, offering a less ethically disputable alternative to embryo cryopreservation,simplifying and making safer oocyte donation, and giving an opportunity forfertility preservation to women at risk of premature ovarian failure as an effectof genetic factors or chemo- or radiother

The human egg - the rarest and most rapidly aging cell in the body - is a topic of intense scientific study. Assisted reproduction clinics are constantly vying to improve success rates - choosing the best gametes is a key step in this process. This new edition of what one reviewer of the first edition described as 'possibly the definitive work on the oocyte' covers the development, biology and pathology of the oocyte, and technologies to manipulate, enhance and control fertility. These technologies are used to overcome infertility, avoid inherited diseases, and create genetically engineered embryos from stem cells and cloning. This progress would have been impossible without the myriad of scientific and technical developments covered in this book. The new edition is thoroughly updated and includes major new research on reprogramming, oocyte molecular development, cryopreservation and viability. We are in exciting times for the egg.

A growing majority of women in the western hemisphere have been delaying initiation of childbearing to later in life. Consequently, more women in their late 30s to early 40s are attempting to get pregnant for the first time than ever before. Since the incidence of most cancers increases with age, delayed childbearing results in more female cancer survivors interested in fertility preservation. In this book, the editors provide strategies for fertility preservation in women and men who require gonadotoxic treatment. In addition, epidemiologic, ethical, medico-legal, psychologic, and social aspects of fertility preservation are discussed. Using a format that combines concise scientific background with practical methodological information and easy-to-grasp algorithms, the chapters all conform to a uniform structure, including a brief abstract, keyword glossary, step by step protocol of laboratory procedures, key issues in commentary and a list of references. The result is a unique, practical reference guide for reproductive endocrinologists, urologists, embryologists, reproductive scientists, and oncologists.

Advances in technology now offer promising solutions to deal with the chronological aging of the cell, tissue or organ to synchronize its existence and its use. This book covers the developments in and benefits of the latest vitrification technology and its extensive applications in reproductive medicine. Protocols of gametes (oocyte and sperm), embryos, blastocysts and ovarian tissue cryopreservation have been reviewed by leaders in the field. In order to address the escalation in cross-border reproductive tourism entailing the transfer of reproductive cells and tissues rather than the patient, the challenges, caution and emerging possibilities of nitrogen vapor shipment of vitrified cells have been discussed. Current perspectives on oocyte banking present the reader with options and solutions to effectively utilize these gametes despite the physiological deterrents.The versatile applications and potential of vitrification of human embryonic stem cells, discussed in the concluding chapter, is an exciting reality offered by vitrification to help overcome numerous stumbling blocks in the management of various disorders.

The specialty of fertility preservation offers patients with cancer, who are rendered infertile by chemo- and radiotherapy, the opportunity to realize their reproductive potential. This gold-standard publication defines the specialty. The full range of techniques and scientific concepts is covered in detail, and the author team includes many of the world's leading experts in the field. The book opens with introductions to fertility preservation in both cancer and non-cancer patients, followed by cancer biology, epidemiology and treatment, and reproductive biology and cryobiology. Subsequent sections cover fertility preservation strategies in males and females, including medical/surgical procedures, ART, cryopreservation and transplantation of both ovarian tissue and the whole ovary, and in-vitro follicle growth and maturation. Concluding chapters address future technologies, as well as ethical, legal and religious issues. Richly illustrated throughout, this is a key resource for all clinicians specializing in reproductive medicine, gynecology, oncology, hematology, endocrinology and infertility.

This book comprehensively addresses female and male fertility preservation. It discusses in detail all major aspects of fertility preservation in both sexes, explains the basis of fertility preservation, and highlights the currently available techniques; further chapters are dedicated to specific diseases. The book offers an essential reference guide for all physicians, specialists or not, seeking to improve their grasp of female and male fertility preservation.

Fertility Preservation: Advances and Controversies is a practical guide to fertility preservation techniques in patients undergoing therapy that may damage reproductive organs, such as chemotherapy and radiation therapy. Divided into two sections, the first part provides in depth discussion on different fertility preservation approaches in females, and the second part examines male fertility preservation. Written by an extensive author and editor team from Canada, the USA and Europe, this concise guide includes detailed algorithms, and numerous images, illustrations and tables. Key points Practical guide to fertility preservation in patients undergoing therapy affecting reproductive organs Examines techniques for both female and male fertility preservation Extensive, internationally recognised author and editor team Includes numerous algorithms, images, diagrams and tables
