Book Description
Highlighting caecilians, salamanders, and frogs and toads, this book synthesizes current literature and original research and describes the anatomy, histology, cytology, and molecular mechanisms that regulate reproductive cycles. Devoting separate chapters to males and females, it discusses gonad structure and development, gametogenesis, urogenital connections, and reproductive tracts. Heavily illustrated with original schemes and photographs, the text investigates somatic and germ cell origin during formation of undifferentiated gonads as well as embryonic and post-embryonic development, direct development, neoteny, and modifications in gametogenesis and meiosis in hybrids and polyploids.

Book Description
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.

Book Description
Sperm Biology represents the first analysis of the evolutionary significance of sperm phenotypes and derived sperm traits and the possible selection pressures responsible for sperm-egg coevolution. An understanding of sperm evolution is fast developing and promises to shed light on many topics from basic reproductive biology to the evolutionary process itself as well as the sperm proteome, the sperm genome and the quantitative genetics of sperm. The Editors have identified 15 topics of current interest and biological significance to cover all aspects of this bizarre, fascinating and important subject. It comprises the most comprehensive and up-to-date review of the evolution of sperm and pointers for future research, written by experts in both sperm biology and evolutionary biology. The combination of evolution and sperm is a potent mix, and this is the definitive account. - The first review survey of this emerging field - Written by experts from a broad array of disciplines from the physiological and biomedical to the ecological and evolutionary - Sheds light on the intricacies of reproduction and the coevolution of sperm, egg and reproductive behavior

Book Description
The Functional Anatomy of the Spermatozoon is the 23rd volume of the series Wenner-Gren Center International Symposium Series, documenting the proceedings of the Second International Symposium on Comparative Spermatology, held in August 1973. This volume mainly focuses on the understanding of the early events at fertilization and the preliminaries of this biological process. This text specifically tackles the sperm at fertilization of lower animals and mammals, sperm motility and diversity, and spermatogenesis. This book concludes with discussions on capacitation and maturation of mammalian spermatozoa. This compendium will be valuable to morphologists, physiologists, immunologists, and biochemists, as well as to academicians interested in the study of functional anatomy of the spermatozoon.
