Available in PDF, EPUB and Kindle. Book excerpt: This valuable reference work provides a synthesis of the latest knowledge about the acrosomatic reaction of human sperm. The acrosomatic reaction, which is a fundamental step in the process of fertilisation, is examined on both the fundamental and clinical levels. Three very recent aspects are also dealt with: what happens to the acrosome during intracytoplasmic microinjections, the usefulness of screening spermatozoa that have completed their acrosomatic reaction, and the development of contraception by a vaccine that targets one of the proteins of the acrosome. International Symposium, Collioure, France, September 1995.

This book was released on 2016-05-19 with total page 176 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the last decades, acrosomal exocytosis (also called the “acrosome reaction”) has been recognized as playing an essential role in fertilization. Secretion of this granule is an absolute requirement for physiological fertilization. In recent years, the study of mammalian acrosomal exocytosis has yielded some major advances that challenge the long-held, general paradigms in the field. Principally, the idea that sperm must be acrosome-intact to bind to the zona pellucida of unfertilized eggs, based largely on in vitro fertilization studies of mouse oocytes denuded of the cumulus oophorus, has been overturned by experiments using state-of-the-art imaging of cumulus-intact oocytes and fertilization experiments where eggs were reinseminated by acrosome-reacted sperm recovered from the perivitelline space of zygotes. From a molecular point of view, acrosome exocytosis is a synchronized and tightly regulated process mediated by molecular mechanisms that are homologous to those reported in neuroendocrinal cell secretions. The authors provide a broader perspective, focusing on a limited number of important topics that are essential for understanding the molecular mechanisms governing this step in the fertilization process. They also discuss molecular aspects such as the signaling pathways leading to exocytosis, including the participation of ion channels, lipids, the fusion machinery proteins and the actin cytoskeleton as well as cellular aspects such as the site of acrosomal exocytosis and the use of gene-manipulated animals to study this process.

Download or read book Controls of Serm Motility written by Claude Gagnon and published by CRC Press. This book was released on 2020-04-23 with total page 592 pages. Available in PDF, EPUB and Kindle. Book excerpt: First published in 1990, this timely book provides the first comprehensive state-of-the-art updates on various aspects of sperm motility. The first section describes in detail the structures, molecules and regulatory mechanisms involved in sperm movement. Also reported are the effects of external milieu and egg factors on the initiation and types of sperm motility. The second section covers how to measure sperm motility in human semen and in capacitating media. The book addresses the prognostic value of motility parameters in cases of infertility. It covers the clinical significance of various drugs and toxins on sperm motility and the clinical management of infertile males with sperm motility defects. This volume is indispensable to biochemists, cell biologists and andrologists interested in cell motility, and to urologists, obstetricians, gynecologists, and endocrinologists involved in the management of infertility. It is of value to those in reproduction, animal science, veterinary science, and vertebrate zoology. The book contains basic and clinically relevant information for graduate students, researchers and clinicians.

Download or read book Human Spermatozoa written by Thomas Lejeune and published by Nova Biomedical. This book was released on 2010-01-01 with total page 545 pages. Available in PDF, EPUB and Kindle. Book excerpt: Spermatozoa is the basic human male germ cell. This gametocyte plays an important role in fertilisation. In the past five years, new improvements in diagnosis have allowed us to assess male fertility potential with a new perspective studying with demonstrated role in sperm physiology. Furthermore, it is demonstrated that infertile men have high levels of sperm DNA damages and a small percentage of spermatozoa from fertile men also possess detectable levels of DNA damage. This book examines several of the factors that may be involved in sperm chromatin and DNA anomalies, including intra and extra testicular factors. Furthermore, sperm capacitation is a complex physiological process that involves biochemical, biophysical, molecular and metabolic modifications of all sperm domains. Some important events related to the capacitation process of sperm is examined as well. The biological role of the proteasome during sperm capacitation and the acrosome reaction and its relationship with protein phosphorylation and dephosphorylation during these processes is explored as well. Other chapters in this book highlight the pivotal role of transmission electron microscopy (TEM) analysis in the diagnosis of human sperm pathologies, the barrier methods currently available to men for regulating their fertility, a discussion of the current understanding of gene transfer to the testis, a new perspectives for the study of mycoplasmal and chlamydial infections of human spermatozoa and a discussion of the present current knowledge on the mechanisms, molecules and cell signalling involved in sperm activating ability.

Download or read book Sexual Reproduction in Animals and Plants written by Hitoshi Sawada and published by Springer. This book was released on 2014-02-07 with total page 463 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book contains the proceedings of the International Symposium on the Mechanisms of Sexual Reproduction in Animals and Plants, where many plant and animal reproductive biologists gathered to discuss their recent progress in investigating the shared mechanisms and factors involved in sexual reproduction. This now is the first book that reviews recent progress in almost all fields of plant and animal fertilization. It was recently reported that the self-sterile mechanism of a hermaphroditic marine invertebrate (ascidian) is very similar to the self-incompatibility system in flowering plants. It was also found that a male factor expressed in the sperm cells of flowering plants is involved in gamete fusion not only of plants but also of animals and parasites. These discoveries have led to the consideration that the core mechanisms or factors involved in sexual reproduction may be shared by animals, plants and unicellular organisms. This valuable book is highly useful for reproductive biologists as well as for biological scientists outside this field in understanding the current progress of reproductive biology.
