The majority of scientists interested in fertilization and early developmental processes will undoubtably have encountered the works of Alberto Monroy at some time in their careers. Alberto's contribution to this field spans oogenesis to embryogenesis, where he used physiological, biochemical and morphological tools to answer a number of basic problems in cell biology. This multi-disciplinary approach, together with his remarkable intellectual flexibility and humour has had an enormous impact on this field and all those fortunate enough to have worked with him. The chapters in this book have been divided into four sections. The initial presentations revolve around late events of gameteogenesis, that lead to a physiologically mature gamete. Probably the most exciting area for research at the moment is the identification of the cytoplasmic mechanisms responsible for the meiotic arrest of oocytes and the factors responsible for initiating their maturation (Chapters 3 and 4). Less is known about the physiological changes in the male gamete in preparation for fertilization and this may be identified as a major area for future research. Although comparable data for the plant kingdom is presently restricted to studies on marine algae, new techniques for isolating angiosperm gametes (Chapters 1 and 17) promise rapid advances in this field. The second section looks at the events and molecules involved in gamete recognition, binding and fusion. One of the most controversial topics is when does sperm-egg fusion actually occur (Chapter 14).

This extensively updated new edition provides an indispensable account of modern in-vitro fertilization practice, building upon the popularity of previous editions. The authors initially give a comprehensive review of the biology of human gametes and embryos, before outlining basic to advanced IVF techniques. New developments in practical techniques and understanding are discussed, including in-vitro maturation, vitrification, preservation of fertility for cancer patients, stem cell technology, preimplantation genetic testing, and the role of epigenetics and imprinting. The revised introduction also incorporates a 'refresher' study review of fundamental principles of cell and molecular biology, now updated with current knowledge of meiosis in human oocytes, embryo metabolism and basic principles of genome editing. With high-quality illustrations and extensive, up-to-date reading lists, it is a must-have textbook for trainee and practising embryologists, as well as clinicians who are interested in the scientific principles that underpin successful IVF.

This book introduces readers to the fascinating interaction of specialized gamete cells, forming the early embryo and a blueprint of new life. Readers will gain a thorough understanding of the complex physiological events and mechanical processes - such as ionic regulation, metabolism and intracellular signalling - to decipher cause and effect in fertilization. Wide-ranging in its approach, this book describes fertilization as a highly conserved mechanism throughout the animal kingdom, taking case studies from echinoderms, ascidians, amphibians and mammals through to other phyla. An excellent companion to undergraduate and postgraduate students of medicine, veterinary and biological sciences, this text provides an underpinning of the mechanisms of fertilization that inform assisted reproduction practice and research in medicine and agriculture. It explores the detailed phases before fertilization: the oocyte as a quiescent cell, attracting its partner gamete, followed by a cascade of pre-determined physiological events, to form the dynamic zygote cell; setting the scene for the early embryo, and beyond.
