Book Description
This atlas provides ultrastructural morphological images of human spermatozoa. Sperm morphology plays an essential role in sperm-oocyte interactions and early embryonic development, and human sperm ultrastructural morphology offers a valuable reference tool for assessing certain etiologies of male infertility and reproductive failure. However, the ultrastructural morphology of human sperm has not been systematically evaluated or thoroughly described in the literature. Using 470 original and unpublished images, the book shows various ultrastructural morphological phenotypes; defects of the sperm head, neck, middle piece, principal piece, and terminal piece; as well as artefacts of sperm ultrastructural morphology and phenomena related to inadequate preparation, demonstrating many sperm phenotypes and surface structural appearances for the first time. As such, it helps researchers and practitioners in andrology, reproductive medicine, and reproductive pathology gain a better understanding of human sperm ultrastructural morphology.

Book Description
This atlas provides valuable information on crucial aspects of sperm examination as well numerous meaningful color illustrations. It discusses successful evaluation of the sperm morphology and the cellular elements other than spermatozoa, enabling readers to unambiguously interpret seminal cytologic images and compare reports for diagnostic, therapeutic and prognostic purposes. With its extensive collection of colored images, the book is intended as a reference resource for students and technicians in the field of andrology as well as practitioners and clinicians in andrology, urology, pathology, IVF and other ART programs

If you had a dependable method for determining the healthiest and most viable conceptus from a cohort of growing preembryos, replacing more than a single one in order to achieve good pregnancy rates would be moot. Sometime in the not-so-distant future, this may be a reality. Taking a step towards that future, An Atlas of Human Blastocysts vividly i

Book Description
In 1964, the Fertilization and Gamete Physiology Research Training Program (FERGAP) was established at the Marine Biological Laboratories, Woods Hole, Massachusetts. Over the course of the next 12 years, under the directorship of Dr. Charles B. Metz, FERGAP brought together, trained, and inspired a generation of students in reproductive biology from all over the world. As students of C. B. Metz and as FERGAP trainees, we would like to dedicate this collected work on comparative mammalian fertilization to our teacher and mentor, Dr. Charles B. Metz. Like a number of authors contributing to this volume, we have been struck by the significant impact that C. B. Metz and FERGAP had on the development of students of reproductive biology. Applying both the classical and molecular techniques of cell biology and immunology to problems of gamete biology, Dr. Metz emphasized a comparative and analytical approach that was reflected in his own research on fertilization in Paramecia, sea urchins, frogs, and mammals. It is hoped that this volume will serve to stimulate students to discover the myriad of fascinating research problems in gamete and reproductive biology. Bonnie S. Dunbar Michael G.

Book Description
This Epub incorporates 37 years of embodied research at Monash & La Trobe Universities, Melbourne, by the author with his colleagues in Australia and overseas (England, Singapore, India, Sri Lanka, Italy & Japan).It is a multi-author, visual presentation of the microscopic structure of human oocytes, sperm and embryos in conjunction with clinical IVF and ART and includes embryonic stem cells, a logical extension of ART.Most of the images were taken with electron microscopes (TEM & SEM), light and phase microscopes (LM) and fluorescent microscopes (FM) with diagrams.Both published micrographs (from our atlases and journals) and also original unpublished micrographs are presented. The printed atlases were scanned and new material was provided on PPT, PDF & YouTube for EPub.The aim of this EPub is to make our research available online for clinicians, scientists & students and posterity.

Book Description
Developmental biology has been transformed recently by discoveries in the fields of molecular biology, cell biology, and immunology. New ways of manip ulating mammalian development are uncovering control mechanisms and ena bling us to apply them in solving practical problems in animal production and human health. This book outlines some of these new manipulations and how they have contributed to the present state of developmental biology. Chapter 1 describes gene transfer by micro injection of cloned recombinant DNA into zygotes. Although the factors that affect transformation frequencies and integration sites are still unknown, such techniques offer a number of exciting prospects. Research models for human disease coula be artificially created and desirable characteristics in agricultural animals could be - hanced. . The theme of cell-to-cell transfer is continued in Chapters 2 and 3. Chapter 2 describes pronuclear transplantation by Sendai virus-induced fusion of the karyoplast with the enucleated embryo. Using this procedure, it has been dem onstrated that both male and female genomes are essential for normal develop ment, although the reason for this is not yet understood. Chapter 3 describes studies on the fusion of whole oocytes. .

Book Description
The analysis of ejaculate, known as the spermiogram, is the crucial investigative technique in the andrological check-up for childlessness. Althoug other impor tant factors such as medical history, physical examination, hormone analysis and tests, biochemical, microbiological, immunological, and genetic tests, and histological and histochemical investigations must all be considered before a final assessment can be made of male fertility, the spermiogram is the guiding factor in estimating the prospects of fertility. Furthermore, the improvement in insemination techniques in recent years and the development of in vitro fertilization have enhanced the importance of the accurate analysis of sperm morphology and function. In view of the multiplicity of andrological investigative techniques listed above, urologists, gynecologists, physicians specializing in endocrinology and immunology, general practitioners, pathologists, and dermatologists are routin ely involved in semen analysis today. We hope in this book to address people working in all these different medical specialities. Having regard for the requirements of daily practice, we will intentionally restrict ourselves to the spermiogram, which we hope to present step by step by means of a large number of illustrations. A substantial part of the book is devoted to the morphological assessment of normal and pathological forms of spermatozoa and other cellular elements, in the form of generously illustrat ed atlas. Dr. Rovan has given us outstanding assistance in preparing the majori ty of photomicrographs.
