Selecting the best embryo to transfer to the uterus is key to successful in vitro fertilization (IVF). A huge amount of research has been devoted to this topic and there are numerous methods used, from simple morphological assessment to molecular biological techniques to assess the genome and metabolism of the newly fertilized embryo. For many of these techniques, an adequate evidence base is lacking, and expert opinion is valuable. Clinical imperatives require ranking all embryos in a cohort according to their viability, thereby enabling the selection of the best embryo to optimize live birth outcome: a key indicator used to measure and rate IVF Clinics worldwide. This clear and informative manual will provide embryologists and clinicians with an overview of the tools now available to assist in embryo selection, as well as evidence for their efficacy and safety and the broader considerations that must underlie these important clinical decisions.
Manual of Assisted Reproductive Technologies and Clinical Embryology aims to discuss the relevance of science of reproductive biology in modern-day Assisted Reproductive Technologies and their practical applications. The readers can learn and master the large number of sophisticated techniques which form the backbone of the fascinating and growing field of human assisted reproduction. The subject is vast and has been covered over 83 chapters. All the chapters are dealt by the experts of concerned fields. Principles and protocols pertaining to laboratory maintenance, culture media, cryofreezing of gametes, embryos, and genital tissues have been dealt with at length. This book is an invaluable reference book for the clinicians, reproductive biologists and embryologists.
Whilst assisted reproduction techniques (ART) have become increasingly successful and largely standardized, there is still only a partial understanding of what constitutes a 'true' embryo environment. Replicating the varying physiological conditions of the in-vivo environment that the embryo travels through in the in-vitro culture is still a major challenge in ART. This practical volume details how to organize and operate an IVF laboratory in order to mimic these conditions for successful embryo culture. Environments and equipment that are essential for running safe and efficient facilities such as maintaining good air quality and hygiene protocols, and utilizing an effective layout are covered in detail. Other chapters discuss the different consumables needed, optimal handling techniques and parameter monitoring systems, as well as recent advances in the area including artificial intelligence and automation. This is an indispensable guide to understanding the background science of culturing embryos, crucial to successful outcomes in ART.
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
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.
"Not everything in medical science has a clear beginning. The first realization of infertility and putative remedies remain shrouded in contextual history, but likely goes back to the dawn of our species, well before there was a written record. Childlessness was, and is still, considered a burden in some communities"--
Our knowledge of reproductive medicine has expanded rapidly since the birth of Louise Brown, the first baby to be conceived by in vitro fertilization, which was performed by Professors Patrick Steptoe and Bob Edwards in Oldham, Eng land, in 1978. Hardly a year goes by without the development of a new or a modification of an existing method of assisted reproduction. Within a relatively short period, in vitro fertilization has been introduced into the treatment of female infertility. Intracytoplasmic sperm injection has also created new opportunities for the treatment of male infertility. The first edition of this book was published in 1996. In the second edition most of the chapters have been updated and additional interest is focused on intracytoplasmic sperm injection (ICSI) in view of the risk of malformations in newborns. This manual addresses the techniques of assisted reproduction that are avail able today. Competent authors from various centers present, in a concise way, their tried-and-tested procedures, so that the latter can be readily implemented. Due to different legal regulations, the scope of assisted reproduction is much more limited in Germany than in many other countries. For example, whereas only three embryos may be created and transferred in Germany, such restric tions do not exist in several other European countries and the United States. Furthermore, heterologous fertilization, oocyte donation, and surrogate mother hood are banned in Germany.
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
The Practical Manual of In Vitro Fertilization: Advanced Methods and Novel Devices is a unique, accessible title that provides a complete review of the most well-established and current diagnostic and treatment techniques comprising in vitro fertilization. Throughout the chapters, a uniform structure is employed, including a brief abstract, a keyword glossary, a step-by-step protocol of the laboratory procedures, several pages of expert commentary, key issues of clinical concern, and a list of references. The result is a readily accessible, high quality reference guide for reproductive endocrinologists, urologists, embryologists, biologists and research scientists. The Manual also offers an excellent description of novel procedures that will likely be employed in the near future. An indispensable resource for physicians and basic scientists, the Practical Manual of In Vitro Fertilization: Advanced Methods and Novel Devices is an invaluable reference and addition to the literature.
This book provides the Assisted Reproduction Technologies (ART) community an update of the fast approaching novel technologies that may allow improved assessment of the reproductive potential of sperm, oocytes and embryos. The reader has access to concise updates on the rapidly developing diagnostic technologies (genomics, transcriptomics, proteomics and metabolomics) and morphological methods which may help us better assess the gametes and embryos. Methodologies are described which enable selection of the best gamete or embryo by invasive and non-invasive diagnostics, as well as the clinical validity of these techniques.
